Description METHOD AND SYSTEM FOR CONVERTING TRANSACTION

INFORMATION INTO MUSIC FILE AND READABLE RECORDING MEDIA USING COMPUTER RECORDING

THEREOF Technical Field

[1] The present invention relates to a method and system for converting information on stock price and trading volume provided by a security company via, for example, the Internet, into user-desired music in real time or in a user-desired period, in which the music is synchronized to music that a user desires to listen to so that the user listens to both the information and the music ("amusement music corresponding to the transaction") and to a recording medium having a conversion program stored thereon.

[2] The present invention can apply to all kinds of transactions including future transactions and auctions without particular knowledge and can represent such transactions in the form of music without departing from the technical spirit of the present invention.

Background Art

[4] In general, stock investment is the most representative example of direct investment. In Korea, stock investors have increased nearly two times around 2000. The Korea Exchange(KRX) issued that, as of 2004, stock investors number about 3.8 million, which corresponds to 16.1% of economically active population and 7.7% of total population. Although the stock investors occupied 8 to 9% of the economically active population in the 1990's, it dropped to 6% in 1997 when IMF control began and has increased to 16% since 1999. Maximum transaction money of a day amounts to 3 to 4 trillion Won and total transaction money in 2004 amounted to 560 trillion Won. It is known that an average age of stock investors is about 45, stock investors aged 20 or older occupying upwards of 99%.

[5] For stock investment, a user needs to continuously monitor stock transaction inf ormation to make a trade decision and should not lose a state of balance by overly concentrating the transaction information. Many investors fail to make trading decisions because they have low information analysis capability, cannot continuously monitor the transaction information and thereby lose important trade timing and more importantly, lose a state of balance and make an unreasonable decision at an important trade time. The present invention enables an investor to maintain a state of balance by

listening to music and assists in taking important trade timing by including transaction information in the music.

[6] In general, as a security term, a chart shows a motion of stock price, bond price and the like in the form of a graph. Examples of the chart include a Japanese candle chart, an American bar chart and a line chart. The chart is a basic tool for technical stock analysis. The candle chart is plotted using opening price, high price, low price and closing price. The candle charts may be classified as daily candle charts, weekly candle charts, monthly candle charts, tick candle charts, second candle charts, minute candle charts and hour candle charts depending on a temporal resolution.

[7] The most important elements for confirming a type of candle chart representing stock transaction include a trading frequency, a trading price and a trading volume. Technical analysis provides a buying time or a selling time by predicting a change in a stock market or price of individual stocks to maximize a capital gain.

[8] Consequently, investors must analyze the candle charts. On a basic premise that a pattern of past stock price is applied to future pattern of stock price, average stock price over one month, three months and six months is calculated and a fluctuations in the average stock price is used to predict a flow of stock price through moving average and divergence. This chart analysis is shown in FIG. 1.

[9] A conventional technique for converting transaction information into sound is disclosed in Japanese Patent Laid-open Publication No. 2002-133111, in which when stock price is changed to above or below a predetermined price, then sound an alarm, or when a customer accesses an web-site providing a transaction information to selelct a specific stock, a name of the proper item, a corporate name and current price are converted into simple sound.

[10] A system for converting security information into sound is disclosed in Korea

Patent Publication No. 2002-0015198 (February 27, 2002), in which the system comprises a plurality of sites providing security information; a plurality of web-sites providing news; a security information and news service server for collecting client- requested security information and/or related news from the plurality of security information providing sites and the plurality of news providing sites and sending the same to the client; and the client for setting a type and a display form of the security information and the news and receiving the security information and the news in the form of the set type and display form from the security information and news service server. Here, a method for providing real-time security information and/or news service includes the steps of receiving client-set stock name, a rise/fall flag and current price from the security information providing site; segmenting a phoneme of the stock name, extracting a speech segment and a rhythm from a database in an order and synthesizing the stock name with sound using the extracted speech segment and rhythm;

decomposing the current price into figures; decimally extracting a rhythm and a speech segment from a database and synthesizing the current price figures with sound; synthesizing a complete sound stream through a combination of the step of synthesizing the stock name with sound and the step of synthesizing the figures with sound; transmitting the stream to a sound output device; and outputting the stock information in the form of sound.

[11] All of the conventional techniques only convert transaction information into simple sound or synthesize the transaction information with sound and do not convert the transaction information into music. Some of the conventional techniques may represent the transaction information in the form of musical sound, such as a bell chime. However, these do not perform a conversion into music reflecting the transaction information. A technique of converting transaction information into music is disclosed in our Patent Application No. 2005-0032309 filed April 19, 2005 and Patent Application No. 2005-0099850 filed on October 21, 2005. These inventions disclose a concept for converting trading price, trading volume and trading frequency in transaction information into a pitch, an intensity and a tempo of sound that are three elements of music. However, these are directed to a technique of converting transaction information to music and do not use or utilize existing music. To increase musical listening, the present invention enables a user to select desired amusement music, recognize features of the music and correspond or convert transaction information to or into the features of the music so that the transaction information is synchronized to the amusement music and played. This allows the user to obtain the transaction information while listening to the music.

[12] However, a conversion of user-desired letters, such as directory information, into sound, as well as provision of current stock transaction status, stock information and the like as audible synthesized sound as described above, is known. In particular, the conventional techniques of providing transaction information or the techniques of providing stock information as described above are an advanced version of a method for obtaining stock information based on visual information, in which specific selected elements in the stock information are converted into audible sound. This method assists the disabled in audibly recognizing a current stock status from visual information while visually performing other tasks. However, they are allowed to listen to simple current information, i.e., a desired trading item and current price of a selected stock only in the form of synthesized sound.

[13] Also, the conventional method merely provides audible instantaneous information such as trading volume, trading money and the like at a selected time and cannot provide audible information required for recognizing continue information or flow for decision making. Besides, the method merely provides an arrangement of numerical

information obtained through, for example, voice synthesis, or alarm and requires a customer who must make a decision in a complex and confused environment to listen to input audible information with minute attention and to analyze the information.

[14] These acts could be heavy stress to the customer who does not give attention to the audible information and loses transaction timing.

[15] Moreover, it is impossible for customer to check security transaction information while performing the other tasks, since the customer needs to view a monitor providing visual transaction information or visit a security company in order to recognize the current transaction status of a specific stock in real time while performing other tasks.

[16] The conventional technique merely represents a fluctuation in stock price by music and does not provide a detailed transaction status of specific trading item desired by the customer.

[17] Also, musical representation of transaction information has been primarily limited to signal sound containing information and there has been a limitation on musical representation. Therefore, A conventional conversion of transaction information into music is merely a combination of phonemes corresponding to transaction information irrespective of user's taste or preferred music to reproduce music, which acts as noise to the customer when extreme concentration is required and tension is caused, thus obstructing comfortable decision making.

Disclosure of Invention

Technical Problem

[19] An object of the present invention is to provide a method and system that enables a user to listen to music to maximize a state of balance, which greatly affects successful investment in stock transaction requiring extreme concentration and causing tension, in which key variables such as trading price, trading volume, trading frequency and trading item are extracted from transaction information and converted into music corresponding to the transaction in association with a chord of existing amusement music preferred by a user, such that the music corresponding to the transaction is played by a user-selected instrument and to provide a recording medium therefor.

[20] Another object of the present invention is to provide a method and system for converting transaction information into corresponding amusement music, in which the transaction information is converted into amusement music corresponding to the transaction and transaction information of interest is provided as the amusement music corresponding to the transaction, so that a user("customer") such as a fund manager or an investor trades for a long time in a stable and comfortable atmosphere and to provide a recording medium therefor.

[21] Still another object of the present invention is to provide a method and system which are capable of properly representing core elements of transaction such as trading price, trading frequency, trading volume and trading item as corresponding amusement music to well represent transaction aspects and converting the transaction information into corresponding amusement music to increase successful transaction by using both the amusement music and existing visual information and to provide a recording medium therefor.

[22] Yet another object of the present invention is to assist a blind person in recognizing transaction information through music.

[23] Still yet another object of the present invention is to assist a customer such as a homemaker or a doctor who cannot monitor visual information continuously due to housework and medical treatment in recognizing transaction information while listening to music and immediately trading in case of occurring a key transaction in fluctuations. Technical Solution

[24] It is necessary to understand meanings of music corresponding to transaction and amusement music corresponding to transaction, which are key terms used herein. Music to be listened to (i.e., amusement music) is selected by a customer, key information such as a chord, time of chaning chord and the like is extracted from the amusement music by a configuration of the present invention and then the extracted information is combined with transaction information to make new music, which is the music corresponding to the transaction. The customer listens to the amusement music as well as the music corresponding to the transaction and simultaneous playing of the music corresponding to the transaction and the amusement music is referred to as the amusement music corresponding to transaction. As a result, an object of the present invention is to make the music corresponding to transaction and synchronize a playing time of the music corresponding to the transaction to a playing time of the amusement music so that the two synchronized musics are harmoniously played. In the present invention, the music corresponding to the transaction is made and then synchronized to the amusement music, thus making the amusement music corresponding to the transaction. Thus, the present invention is to making amusement music corresponding to the transaction. A customer obtains a state of balance from the amusement music and the transaction information from the music corresponding to the transaction. A customer desiring amusement may increase output volume of the amusement music and a customer desiring the information may freely adjust an output pattern of the amusement music corresponding to the transaction in a manner that increases the output of the music corresponding to the transaction. To accomplish the two purposes,

the present invention uses a music chord so that the music corresponding to the transaction is synchronized to and played with the amusement music. That is, when the chord of the amusement music and the chord of the music corresponding to the transaction are changed at the same time, the music corresponding to the transaction is synchronized to and played with the amusement music.

[25] According to a first aspect of the present invention, there is a method for converting transaction information into audible amusement music corresponding to the transaction, the method comprising the steps of: receiving the transaction information; and converting the transaction information into the amusement music corresponding to the transaction. The transaction information includes trading frequency, trading price, trading volume and trading item. The step of converting the transaction information into a music file includes converting elements of the transaction information into sound elements and combining the converted sound elements to sound. The trading frequency is converted into a tempo of sound, the trading price into a pitch of a chord of the amusement music, the trading volume into an intensity of the sound and the trading item into a tone of an instrument.

[26] In the method, the step of converting the transaction information into an amusement music file corresponding to the transaction further includes converting a pitch of a chord and a sound intensity of the amusement music and converting the same into amusement music corresponding to the transaction in each transaction time slot.

[27] In the method, the transaction information is real-time transaction information.

[28] In the step of converting the transaction information into the amusement music file corresponding to the transaction, a trading frequency in a resolution of 1/100 seconds is 32nd-note quantized. A conversion of the trading price into a chord pitch of the amusement music uses average price over a transaction period, closing price of a previous day, opening price of today and opening price every hour as a reference sound pitch (if the chord of the amusement music is the highest sound, it is changed into the lowest sound when transaction money increases). A conversion of the trading volume into an intensity of sound uses a division of a trading volume between a maximum trading volume and a minimum trading volume in the transaction period into eight or a division of the trading volume into eight using an average trading volume of a previous day as a center.

[29] In the method, the conversion of the trading frequency into a sound tempo is made by repeatedly performing a step of conferming whether there is transaction information within a specific time from a reference time, a first confirmation step of confirming a length of a first musical note of the chord of the amusement music when there is transaction information, a first transaction information confirming step of confirming a second musical note length of the chord of the amusement music to confirm whether

there is transaction information in a specific period of time, a second transaction information confirming step of confirming a third musical note length of the chord of the amusement music to confirm whether there is transaction information in a specific period of time and a third transaction information confirming step for confirming a fourth musical note length of the chord of the amusement music to determine whether there is transaction information in a specific period of time (In this case, the repetition may be changed depending on a number of musical notes of the chord of the amusement music).

[30] According to a second aspect of the present invention, there is a system for converting transaction information into audible music corresponding to the transaction, the system comprising: a receiver for receiving the transaction information, and a transaction information processor for extracting transaction information corresponding to a phoneme from the received transaction information and processing the input transaction information, and a chord extractor for extracting a chord from the amusement music, and a music file converter for converting the transaction information into music corresponding to the transaction and, a conversion data table for converting the extracted transaction information into amusement music and, a storage unit for storing customer information and the received transaction information or the amusement music corresponding to the transaction, and a transmission and reception controller for controlling communication with a security company, a customer, a certification authority, or a financial institution via a wired/wireless communication network including the Internet, and a controller of a server for controlling components of the server including the transmission and reception controller and the music file converter, wherein: the transaction information includes trading frequency, trading price, trading volume, and trading item, and the trading frequency is converted into a tempo of sound, the trading price into a pitch of a chord of the amusement music, the trading volume into an intensity of the sound, and the trading item into a tone of an instrument.

[31] According to a third aspect of the present invention, there is a recording medium having a program recorded thereon for converting transaction information into audible amusement music corresponding to the transaction, the program comprising: a process of receiving the transaction information and a process of converting the transaction information into the amusement music corresponding to the transaction, wherein: the transaction information includes trading frequency, trading price, trading volume and trading item, the process of converting the transaction information into the amusement music corresponding to the transaction comprises a process of converting elements of the transaction information into a chord, an intensity and a sound tempo of the amusement music ("elements of the amusement music"); and a process of combining

the converted elements of the music and the trading frequency is converted into the sound tempo, the trading price into a pitch of the chord of the amusement music, the trading volume into the sound intensity and the trading item into a tone of an instrument.

Advantageous Effects

[32] As described above, in the method and system for converting transaction information into corresponding amusement music, and a recording medium therefor according to the present invention, a security information and/or news service method and system that enables a customer such as a fund manager to view security information and/or news information in the form of characters and/or sound is capable of providing audible stock transaction information so that the customer recognizes current stock transaction status of a desired stock while performing other tasks and listening to preferred amusement music. Thus, the customer can recognize the transaction information and make a decision while performing other tasks, thus leading to high task efficiency.

[33] According to the invention, a transaction change pattern can be more accurately recognized by music or felt in other aspects, a customer can simultaneously listen to a plurality of current transaction statuses through desired sound, and a musical atmosphere for maximizing task efficiency is introduced to a transaction task so that the customer performs efficient transaction in a comfortable atmosphere for a long time.

Mode for the Invention

[57] Hereinafter, exemplary embodiments of the present invention will be described in detail. However, the present invention is not limited to the exemplary embodiments disclosed below, but can be implemented in various types. Therefore, the present exemplary embodiments are provided for complete disclosure of the present invention and to fully inform the scope of the present invention to those ordinarily skilled in the art.

[58] FIG. 2 is a block diagram illustrating a transaction information and news service system according to the present invention.

[59] Referring to FIG. 2, a security information providing site 120 is a security company, the Korea Exchange, the KOSCOM, or the like that is providing security information via the Internet, a security certification authority is the National Information Society Agency, and a financial institution includes a commercial bank or a special bank.

[60] A server 110 searches for and stores transaction information including stock price in real time from the security information providing site 400, e.g., the KOSCOM, and sends real-time data or past data to a customer 100 via a wired/wireless communication network, such as the Internet, a private communication network, or the like.

[61] A configuration of the server 110 will now be described in detail. The server 110 includes a transaction information processor 310 for processing transaction information received from the transaction information providing site 120 such as a security company (hereinafter "security company"), extracting transaction elements or

performing computation under a server operator-set condition, and extracting transaction information required for forming music data from the received transaction information; a customer manager 340 associated with a security agency or a financial institution for performing customer identification or billing; a transaction-music converter 350 for converting the processed transaction information into corresponding music; a storage unit 360 for storing a transaction-music conversion data table for converting the extracted transaction information into phoneme, customer information, the received transaction information, and music corresponding to the transaction; a player 370 for playing the music from the transaction-music converter 350; a music storage unit 380 for storing amusement music; a transaction-music conversion data table 390; a chord extractor 400 for extracting a musical score chord from the amusement music; a transmission and reception controller 330 for controlling communication with a security company, a customer, a certification authority, and a financial institution via a wired/wireless communication network such as the Internet; and a controller 320 for controlling all components of the server including the player 370, the transaction-music converter 350, the chord extractor 400, and the music storage unit. Other components required for E-commerce will not be described. However, the server includes components for E-commerce, such as a data storage device; communication software; an input/output device for processing, editing, searching, displaying, and outputting data; and a device for converting musical score data into a MIDI file and playing the MIDI file through an acoustic player.

[62] A process for converting transaction information into a music file will now be described with reference to flowcharts shown in the drawings. In the flowchart of the present invention, a certification process for customer identification, a process of checking an ID for member management, and a billing process for use of service of the present invention are the same as or similar to those in a known E-commerce system and method. Accordingly, a detailed description of the above processes will be omitted.

[63] First, it is necessary to extract variables, i.e., a stock price change, a trading frequency, a trading volume, and a trading item from the transaction information in order to represent the transaction information as music. The transaction information must correspond to "elements of amusement music", such as a pitch of a chord of amusement music, sound tempo, sound intensity, a tone of instrument, and the like. Furthermore, the elements of the music, the chord pitch of amusement music, sound intensity of a chord, the sound tempo as an inter-chord interval, and the instrument tone are required to represent the transaction music as the amusemnet music corresponding to the transaction. Accordingly, trading price, trading volume, trading frequency, and trading item in the transaction information at a certain instant must

correspond to the elements of the music to represent as the music corresponding to the transaction.

[64] Usually, the trading frequency indicates how often transactions occur. In real-time transaction information, tick data is indicated in a resolution of 1/100 seconds, and corresponds to sound generation frequency, i.e., a sound tempo.

[65] However, since the tempo in music is relative, the number of sounds ringing for one second is of importance. When four transactions occur for one second, 4/4 time representation in MMJ =60 results in .

[66] Provided a person can listen to 20 sounds for one second, about 64th-note representation is possible. However, because 10 actual transactions or greater rarely occur in one second, the real-time transaction information, when represented by the tempo, is likely to be converted musically. One problem is that when tick data in a resolution of 1/100 seconds is represented by a musical score, time is too complicated and a resulting sound is not musical. Hence, 32nd-note quantization by MIDI functionality is proper.

[67] This may be used to convert a musical note of the amusement music according to the trading frequency, but the conversion is impossible in the case of chord. Accordingly, in the present invention, the trading frequency corresponds to an inter-chord interval to play.

[68] FIG. 3 illustrates an example of future transaction. In FIG. 3, 09035790 on a time item indicates 9:3:57:90 in a resolution of 1/100 seconds, and 6 transactions occur in a period of 58 seconds. For reference, 32nd-note quantization may result in a musical score as shown in FIG. 4, which corresponds to a musical note of the amusement music for conversion.

[69] For reference, when trading price is represented by music, a rise in the trading price may increase a sound size and a fall in the trading price may decrease the sound size. There is a difference in a trading price and a rise/fall width between trading items, but it is possible to know a highest price and a lowest price in an analysis range. Accordingly, a price range may be scaled into 128 levels and caused to correspond to MIDI.

[70] In the present invention, the trading price is represented by a change in the pitch of the chord, i.e., the pitch of the chord of the amusement music, which is described in association with a change in capo's location of a guitar.

[71] However, when the chord of the amusement music is set to the highest sound referenced to change the pitch of sound, the lowest sound is returned to indicate an increase. When the chord is set to the lowest sound referenced to change the pitch of sound, the highest sound is returned to indicate a decrease.

[72] For the trading volume, when the transactions do not occur frequently and many

transactions occur abruptly, investors are strained. The trading volume may be represented by the sound intensity. In the simplest example, a trading volume of the future in a range of 1 to 200 may be represented in 8 levels, as shown in FIG. 6.

[73] However, a great interval between the highest value and the lowest value of the trading volume makes it difficult to recognize a change in sound intensity. This issue may be solved by the following two methods:

[74] First, a tone change may be used together to use dark and thick sound at low sound and light and sharp sound at high sound. Second, an exponential function may be introduced to cause the sound size to more greatly change in a sensitive price range. However, fine adjustment may be required to cause a musically proper change in the sound size instead of representing strong sound at an abrupt change in the sound intensity, so that a customer obtains information while listening to the music.

[75] According to the present invention as described above, when past transaction or a frequency of real-time transaction is represented as corresponding music, it corresponds to an inter-chord interval of the selected amusement music. This may be changed by the customer.

[76] [77] Table 1

[78] [79] An example of correspondence between trading price (e.g., an opening price, a low price, a high price, and a closing price) and the pitch of the sound is shown in Table 2.

[80] In general amusement music, a chord of a musical score C- is indicated by Do, Mi, and Sol, Cm- is indicated by Do, Mib, and Sol, C#m- is indicated by Do#, Mi, and Sol#, C7- is indicated by Do, Mi, Sol, and Sib, Dm- is indicated by Re, Fa, and La, and C maj7- is indicated by Do, Mi, Sol, and Si.

[81] The pitch of the chord of the amusement music may be represented by 12 levels as

shown in Table 2 (when a guitar capo's location is changed).

[82] Accordingly, the present invention enables the chord of the amusement music to be extracted and played with sound pitch varying with the trading price. A user sets a reference pitch depending on a closing price of a previous day and an opening price, and a sound pitch varies with a change width of a trading price to convert the amusement music into the music corresponding to the transaction. In Table 2, any price is set as a reference value (105.8=level 6) by a user, and the sound pitch of the chord of the amusement music is determined depending on a difference with the reference value.

[83] [84] Table 2

[85] [86] A trading volume (i.e., stock number) on a left column may correspond to the sound size of the chord on a right column, as shown in Table 3.

[87] [88] Table 3

[89] [90] The above conditions are only set by the present inventor to represent real-time transaction information (e.g., future data provided in real time by the KOSCOM or a

security company) in the form of corresponding music, and may be changed selectively by the user without departing from the technical scope of the present invention.

[91] Variables in the transaction information associated with the elements of the amusement music are combined and converted to music corresponding to the transaction, which is formed as a music file and played by any known music-file playing software and system.

[92] The music may be formed as the music file through a process in which a known synthesizer generates a specific digital signal and converts the same into a MIDI file for playing. That is, a user of the above transaction information organizes signals corresponding to the transaction information such as the above condition into a table or a database, and inputs a digital signal corresponding to a musical note formed according to transaction variables to the synthesizer in order to convert the same to a MIDI file. An example of software of converting a digital signal to music data, MIDI data includes "MAX" (available from the France media information association, Cycling 74).

[93] Various modifications may be made to the exemplary embodiment of the present invention.

[94] For example, the amusement music may be output from one of left and right speakers and the music corresponding to the transaction may be output from the other. The amusement music and the music corresponding to the transaction may be both output from the respective speakers.

[95] A tone indicating the transaction information, i.e., a type of an instrument, an instrument indicating real-time transaction information, an instrument indicating the same period of a previous day, or types of services or instruments to be listened simultaneously may be selected.

[96] A method for converting transaction information into corresponding music in order to provide the transaction information in the form of music by using an information communication network, such as the Internet, or a system according to an exemplary embodiment of the present invention will be described with reference to FIG. 7.

[97] In FIG. 7, a server for converting transaction information into corresponding music in order to provide the transaction information in the form of music (hereinafter "a transaction information providing server providing music" or, for ease of illustration, "server") receives customer-requested information, such as a stock name, a chord number, or a company name (hereinafter "stock item"), a period, and the like to be listened to as music, from a customer, and useful information, such as transaction information from the KOSCOM (SlOOO); extracts the transaction information over a customer-desired period (S2000); converts the extracted transaction information into

corresponding music (S3000); and transmits the music to a customer's terminal (S4000) in order to provide transaction information in the form of music.

[98] Referring to FIG. 8, the step of receiving the transaction information (SlOOO) includes analyzing the customer-requested information received from the customer (Sl 100), accessing by the customer, the KOSCOM or other transaction information database depending on a period of the selected stock or a customer-requested condition (S 1200), and receiving information such as stock transaction data (S 1300).

[99] In general, a service company providing the transaction information analyzes stock price information over a period of 1 day, 1 week, 15 days, 30 days, 45 days and 60 days and provides a trading price, a trading volume, and the like in the form of a bar graph or a bent-line graph. The KOSCOM, the Korea Exchange or the like provides the current transaction status in real time.

[100] Although not shown in FIG. 7, the information extracting step may be further repeatedly performed a predetermined number of times until the information is extracted in the customer may be requested to change the requirement.

[101] FIG. 9 is a flowchart illustrating a method of converting transaction information to corresponding music according to an exemplary embodiment. First, the server 110 recognizes desired information from customer information and filters, and extracts only information required for converting into the corresponding music from input transaction information (S3100).

[102] In the present invention, examples of the required information include a trading price, a transaction time, a trading volume at each transaction time, and a trading item. The server 110 recognizes from the customer information whether the customer desires simple sound or the music corresponding to the transaction (S3150).

[103] If the customer desires the music corresponding to the transaction, the server 110 selects music to listen from the amusement music storage unit 380 (S3151), and the music chord extractor 400 extracts a music chord, a size of chord sound, or an inter- chord interval of amusement music from the selected amusement music and stores the same (S3152).

[104] As known software for converting a digital signal into music data, MIDI data,

"MAX" (available from the France media information association, Cycling 74) is used. Method for extracting the chord information of the amusement music may be obtained from an existing music book.

[105] A determination is made as to whether the customer desires to listen to real-time transaction or past transaction (S3160). S3150 and S3160 Steps may be performed in a reverse order.

[106] If it is determined in step S3160 that the customer desires to listen to the real-time transaction, a tempo is set depending on the trading frequency (S5000), a chord pitch

of the amusement music, i.e., a reference sound pitch is set depending on the trading price (S6000), a sound intensity is set depending on the trading volume (S7000), and a tone is set depending on the trading item name (S7500). If it is determined in step S3160 that the customer desires to listen to the past transaction, a tempo is set depending on the trading frequency (S8000), a chord pitch of the music is set depending on the trading price (S9000), a sound intensity is set depending on the trading volume (SlOOOO), and a tone is set depending on the trading item name (SI lOOO).

[107] The elements of the music corresponding to the transaction are then determined

(S 12000).

[108] A process of converting real-time data and past transaction into corresponding music according to a first exemplary embodiment will now be described with reference to FIG. 10. Table 4 is an example of the transaction information provided by the KOSCOM.

[112] The server 110 extracts only time information using a data dispersive filter to extract the trading frequency from the information as shown in Table 4, extracts information on a trading price column from the transaction information providing trading

price in each time slot, sets the extracted information as trading price information, and extracts trading volume information in each time slot to extract the trading volume.

[113] Specifically, the server 110 receives transaction information of a stock selected by the customer, and extracts transaction information to convert the transaction information into music corresponding to the transaction (S3100). Here, if the transaction information is real-time transaction information, the server 110 continuously filters input information and then proceeds to step S3170.

[114] The transaction information in the filtered data to be converted into corresponding music, such as the trading volume, the trading price, and the trading time, is stored (S3170).

[115] That is, the server 110 extracts security transaction information in a period set by the customer or real-time security transaction information currently provided by a security company. The server 110 extracts desired information from the transaction information, as described above. The server 110 converts the extracted trading price, trading volume, trading frequency, and trading item name into a music file, i.e., a MIDI file that can be reproduced as music by a known sound card.

[116] In the present invention, the trading price is set as the chord of the amusement music every transaction time in the transaction information. That is, the transaction price between a highest price and a lowest price to be converted into the corresponding music is divided into 12 levels for a guitar capo. Although the guitar is illustrated for ease of illustration, a type of guitar or other instrument in which capo's location can be changed may be selected by a customer.

[117] For illustration, an intermediate value of the day is used to extract a chord from the amusement music and is used as the pitch of the chord corresponding to an intermediate location of a guitar capo (when the transaction is the past transaction).

[118] To convert the real-time information into a music file, a closing price of a previous day may be used as a reference sound, i.e., an original chord of the amusement music. Opening price of today, opening price every hour, and opening price every minute may be freely changed as a price for reference sound by a user. When an intermediate value of the day is used as a capo's intermediate to convert the past data into music, the server 110 first extracts a highest trading price and a lowest trading price in a requested conversion period from input transaction information, and calculates a center value (S3200). In the case of the real-time transaction information, a trading price in each input time slot is extracted with a closing price of a previous day being used as a reference. For ease of illustration, the past transaction will be described because the real-time transaction is the same in a converting process as the past transaction except for input transaction information.

[119] A trading price in each transaction time slot is converted into a pitch of a chord,

with a center value of the chord being used as a reference (S3300). This is shown in Table 5. That is, the highest price is 109.10 Won and the lowest price is 102.70 Won in a set period of the input transaction information in order to convert transaction information between 09:03:00 and 09:03:59 into a music file.

[120] When the trading price is divided into 12 levels, 102.70 Won corresponds to level " 1 " and 109.10 Won corresponds to level " 12". When the levels are represented by chords of the music corresponding to the MIDI data as shown in the above table, the highest price, which is the shortest string length of a guitar, i.e., the farthest capo location from a guitar string adjuster, corresponds to level 12. Other trading prices are shown in Table 5. If the data is real-time data, a closing price of a previous day may be selected by the customer, used as a pitch of the chord of the amusement music, and set as a reference.

Musical data of trading price is represented as pitch of chord

[123] [124] Digital data represented by an electronic musical score containing only the chord pitch in a transaction time order is temporarily stored. The temporarily stored data containing only the chord pitch is sent to a MIDI instruction interpreter so that the music corresponding to the transaction played with a selected tone. Here, the trading price is converted into an electronic musical score containing the chord pitch. The music corresponding to the transaction is obtained by changing only the pitch of the chord in the amusement music, in which a sound length (i.e., tempo) and a size of chord sound are not reflected.

[125] In the present invention, the trading price is divided into 12 levels, which may vary with a type of an instrument, a chord pitch of which may be changed through a chord

change.

[126] The server 110 converts the trading price into corresponding music using a known technique as described above (S3400). Then, The server 110 determines the pitch of the chord based on the trading price, and converts the trading price into a corresponding music only the chord pitch of which is changed, a sound length is not changed, and an intensity of chord sound is not reflected.

[127] For each chord of the music corresponding to the transaction, only the pitch of which is set, the intensity of the chord sound is then set. That is, the intensity of the set chord sound is set in proportion to the trading volume, i.e., the intensity of the chord sound is set depending on the trading volume in money traded at a selected time.

[128] Specifically, a trading volume for setting the intensity of the chord sound is first extracted at a transaction time when the trading price is extracted (S3500).

[129] The extracted trading volume is converted into corresponding music by the customer in a step of converting the intensity of chord sound depending on the trading volume (S3600).

[130] That is, if the data is past data, trading volume between the highest trading volume and the lowest trading volume in the selected range is divided into 8 levels, with level 5 being used as mf to represent the intensity of sound.

[131] Division of the trading volume into 8 levels corresponds to representation of the intensity of sound on the musical score as 8 levels, and the number of levels is merely selected by the inventor. Accordingly, a change in the intensity of sound reproduced by a speaker depending on the trading volume may be amplified to be audibly felt by the user. On the other hand, a too large change in the sound may be reduced.

[132] If the transaction information is real-time transaction information, the intensity of chord sound may be set using a trading volume corresponding to a closing price of a previous day as a reference.

Trading volume information is represented as musical data

[135] [136] The intensity of sound for each musical note in the chord according to the exemplary embodiment is shown in Table 6. Here, the intensity of chord sound corresponding to the trading volume is relative. The more the trading volume, the higher the sound intensity. A size of a digital value that is sound intensity data of the musical note may be converted into a data format suitable for a MIDI file standard by a system operator for compatibility or correspondence with a MIDI file. A table of intensities of chord sound set in proportion to reference chord sound corresponding to the trading volume, when required, may be established in advance and used.

[137] After the intensity of the chord sound corresponding to the trading volume is set as described above, a chord, the sound pitch of which is changed and stored in step S3400, is extracted, and the music corresponding to the transaction is stored, in which the intensity of chord sound is changed in the chord data, the chord pitch of which is changed (S3700).

[138] This music is the music corresponding to the transaction in which there is a change in only the trading price and the trading volume. [139] Only an intensity of the chord sound in which there is no change in the music chord and there is a change in only the pitch of the chord may be stored as the customer desires. That is the music does not reflect the trading price but only the trading volume. The music corresponds to the transaction in which there is no change in the chord and there is a change in only the intensity of the chord sound in the amusement music.

[140] Here, the server extracts a trading frequency for setting a chord interval to cause the trading frequency to correspond to an inter-chord interval (S3710).

[141] If the transaction is real-time transaction, the server waits until next transaction information is input and then determines an interval between an initial chord and a next chord.

[142] In setting the trading frequency as an inter-chord interval, the server extracts the number of transactions in a predetermined period of time to set the inter-chord interval.

[143] For example, when a transaction occurs between 0.25 seconds and 0.50 seconds following an initial transaction, a playing interval is the same as that of reference amusement music. If a transaction occurs between 0.51 seconds and 0.75 seconds, the playing interval is a 1/2 time interval when the reference amusement music is at 1/4 time interval. When the transaction occurs between 0.01 seconds and 0.24 seconds, the playing interval is a 1/8 time interval. The playing interval may be adjusted in a range of amusement music by those skilled in the art, based on a change in the trading frequency in actual transaction.

[144] The trading frequency is converted into an inter-chord interval by using the above extracted trading frequency as a reference (S3720) and the inter-chord interval is stored (S3730).

[145] Here, the stored data is the music corresponding to the transaction the chord pitch of which is converted according to the trading price, the intensity of chord sound corresponding to the trading volume is reflected, and the inter-chord interval corresponding to the trading frequency is reflected.

[146] It will be easily appreciated that the stored data may be music corresponding to transaction obtained by reflecting only the inter-chord interval in the amusement music, as desired by the customer.

[147] For the music corresponding to the transaction converted by the transaction-music converter 350 in the server, a first chord is completed using the pitch of sound of the converted chord, the sound intensity, and the trading frequency data, and stored (S3800). Second transaction information is input and a second chord of music corresponding to the transaction for the second transaction is formed. In this case, the above-described process of forming the music corresponding to the transaction (S3170 to 3800) is repeatedly performed

[148] The customer can listen to the trading price and the trading volume in the form of the music corresponding to the transaction obtained by changing the chord pitch, the size of sound, and the inter-chord interval ("tempo") of the amusement music.

[149] By performing the above steps, an electronic musical score set by the chord pitch corresponding to the trading price, the sound intensity corresponding to the chord pitch, and the tempo corresponding to the trading time interval is produced each time transaction occurs. The server stores music file data of the produced music corresponding to the transaction in its storage device or transmits the same to the customer

to be played (S4000).

[150] A process of converting the above transaction information into amusement music corresponding to the transaction will now be described with reference to FIG. 11.

[151] FIG. 11 is a flowchart illustrating a method for converting transaction information into amusement music corresponding to transaction according to the present invention.

[152] First, transaction information is input, for example, from the Korean Exchange

(SlOO), and then information of interest desired by a user is extracted from the input transaction information (SI lO).

[153] Meanwhile, amusement music is selected from a typical music database in order to convert transaction information into amusement music corresponding to the transaction (S 120). And, at least one of a tempo, a chord or a chord change time of the amusement music is extracted from the amusement music (S 130). Thus, a chord and a time signal are extracted in step S 130.

[154] A chord based on existing music is then produced in order to convert the transaction information into amusement music corresponding to the transaction based on the information extracted in steps Sl 10 and S130 (S140). In this step, the trading price in the transaction information is converted into at least one of the pitch of the chord of the music corresponding to the transaction, the trading volume is converted into the intensity of the chord sound, and/or the trading frequency is converted into the inter- chord interval.

[155] When transaction occurs, the music corresponding to the transaction is then synchronized to the amusement music based on the time signal extracted in step S 130 and according to the chord produced in step S 140 (S 150).

[156] A MIDI sound source from the data synchronized in step S 150 is then played

(S160), the existing music selected in step S120 is played (S170), and user-desired musical elements in the played MIDI sound source and the selected existing music are controlled (S 180), such that the user simultaneously listens to the music corresponding to the transaction and the amusement music through a speaker of a user device.

[157] In the present invention, a selection of the tone, i.e., the instrument corresponding to the trading item has not been described in detail because the selection is the same as in a conventional technique in which a user, i.e., a customer is allowed to select the instrument.

[158] When the customer desires to reproduce the music corresponding to the transaction, he/she simply selects or requests music corresponding to the transaction formed by the selected instrument from the server. The selection has not been shown or described in detail because the customer selects an instrument suggested by the server after or before step S3150 or the server provides a desired instrument.

[159] Although in the present exemplary embodiment, the trading frequency, the trading

price, the trading volume, and the trading item in the transaction information have been described as being converted into the chord length, the intensity of chord sound, and the tone of the amusement music in an order of the inter-chord interval, the chord pitch, and the like, it will be appreciated that they may be converted simultaneously by those skilled in the art as they desire or depending on system's performance. The order may be changed without departing from the technical scope of the present invention only if the trading frequency, the trading price, and the trading volume extracted from single transaction information can be converted into a music file containing the inter- chord interval, the chord pitch, and the intensity of chord sound.

[160] Thus, the present invention covers the technical spirit that those skilled in the art convert transaction information into music. It will be easily appreciated that use of other instruments or simultaneous and individual conversions are covered by the present invention. Although the present invention has been described with respect to the stock transaction information, it will be easily appreciated that the present invention may apply to all transactions generating key transaction information such as transaction time, trading volume, trading price, and trading item, like the stock transaction.

[161] In the present invention, the method for converting the transaction information into corresponding music as described above may apply to a computer-readable recording medium having a program stored thereon for converting the transaction information into music corresponding to the transaction.

[162] While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
