WIPO Patent Application WO/2008/110790
Kind Code:
A2
Abstract:
A system and method for data acquisition and processing is described which can form the basis of new and improved business and consumer services. Audio datagrams such as short duration audio-recordings made from radio or television broadcasts or from a CD player or an MP3 player or the like are captured using a microphone associated with a multimedia computer or mobile phone or PDA or fixed line device and processed to create a digital audiogram dataset which may be subsequently transmitted to a data processing server which comprises a music and or audio archive. A server receives and processes the digital audiogram dataset to enhance the captured audio data and convert it into a suitable format which matches the format of the audio data stored in the server archive. A search engine processes the received digital audiogram and attempts to match the captured audio data with data stored in the archive. When a successful match is made between the audio datagram such as with a genuine piece of music by a recognised artist, a message is sent back to the device which initiated the audio capture and transmission process, or to an email address registered to the device, indicating the name of the artist and the name of the song and details where the music or recorded broadcast can be obtained. The audio datagram capture-and-search process may form part of a service profile for a mobile subscriber and it may be directly linked with a mobile payment transaction service so that the subscriber may order and buy a copy of the music or broadcast directly.

Description:

SYSTEM AND METHOD FOR DATA ACQUISITION AND PROCESSING

DESCRIPTION

BACKGROUND OF THE INVENTION

The current invention relates to a system and method for data acquisition and processing. In particular, the invention relates to a system and method for capturing and or processing a stored or received short duration audio recording or audio datagram such from broadcasts by radio or television or from music being played via a CD player or an MP3 player or an MP4 player for the purpose of determining information about the broadcast such as the artist, the name of the music and the like.

More particularly, the invention relates to a system and method for capturing and or processing stored or received short duration audio recordings or audio datagrams such as from radio or television broadcasts or being played via a CD player or an MP3 player or an MP4 player and the like wherein the short duration audio recordings or audio datagrams are captured using a microphone associated with a mobile phone or PDA or fixed line device and processed to create a digital audiogram dataset which may be subsequently transmitted to a data processing server which is directly linked to a music and or audio archive. The dataset is received by the server and the digital audiogram is processed to enhance the captured audio data and converted into a suitable format which matches the format of the audio data stored in the server archive. A search engine processes the received digital audiogram and attempts to match the captured audio data with data stored in the archive. When a successful match is made between the audio datagram such as with a genuine piece of music by a recognised artist, a message is sent back to the device which initiated the audio capture and transmission process, or to an email address registered to the device, indicating the name of the artist and the name of the song and details where the music or recorded broadcast can be obtained. The audio datagram capture-and-search process may form part of a service profile for a mobile subscriber and it may be directly linked with a mobile payment transaction service so that the subscriber may order and buy a copy of the music or broadcast directly.

This patent application extends the invention of an earlier patent application United Kingdom Patent Application 0619761.0 by the same applicant entitled System and Method for Data Acquisition and Processing having priority date October 6 th 2006. In this patent application is taught the method of using datagrams and combining these with user profiles stored within the data capture device, such as a mobile phone or PDA, to create a range of differentiated services.

The current invention can be considered as key inventive extensions of this technology towards the provision of new and exciting and efficient services which are based upon capturing a short duration of audible data which forms part of broadcast programmes or broadcast music using a device with a microphone such as a mobile phone or PDA or multimedia computer or fixed line device.

Today, mobile network operators and mobile phone and multimedia computer manufacturers are seeking business solutions and technologies which exploit the untapped potential of the mobile phone or PDA or wireless laptop in order to render it as the intelligent device for desirable consumer and business oriented transaction services. The processing capability of the mobile phone is greatly increasing and the term 'multimedia computer' is more frequently being used to describe it.

Nevertheless, many challenges are facing the mobile network operators as consumers seek data-rich and focussed information services and progressively view the mobile operators as managed high-capacity bit pipes offering multi- bearer (GSM, GPRS, 3G, WLAN, WIMAX et al) access networks. Even the search engine companies themselves are offering relatively few solutions which can be offered by way of the mobile phone to reduce churn and increase subscriber loyalty. Current initiatives merely involve directing adverts to Internet web surfers based upon their history of surfing. A business model based upon generally random wanderings through the internet faces many challenges.

The mobile phone comprises several key technical components which are not successfully exploited to their full. The microphone and auditory capture processing capability of wireless devices is of high capability and it offers itself for other services. Analogue sound can be captured over a wide frequency range and digitalised to form a highly accurate dataset of audio data. This can offer the basis of a music search engine service and other similar services whenever a person wishes to know the name of a piece of music or other information about a broadcast transmission.

Often persons hear tracks of music, such as orchestral works or popular music from artists, which they find immediately pleasurable. It is often difficult to determine who the artist is or the name of the music which is being played or who is playing it so that a copy of the music can be purchased. If it were possible to create a solution which enabled a person to capture a short duration of an audio broadcast and process it into an audio dataset which could be sent to a remote server in addition to data indicating the source of the request and or details of the requester such as an email address and the like, and wherein the audio dataset is identified, then the person could receive information to identify and or to purchase the music.

Further to the limitations of existing methods used for identifying audio broadcasts and the creation of new and exciting consumer services, and so far as is known, no optimum system and method for data acquisition and processing is presently available which is directed towards the specific needs of this problem area as outlined.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates a schematic showing how audio data is captured and processed according to one embodiment of the invention. FIG. 2 illustrates the sequence of actions performed on the captured audio data and how it may be processed by the audio archive.

DESCRIPTION OF A PREFERRED EMBODIMENT

Reference will now be made in detail to some specific embodiments of the invention including the best modes contemplated by the inventor for carrying out the invention. Examples of these specific embodiments are illustrated in the accompanying drawings. While the invention is described in conjunction with these specific embodiments, it will be understood that it is not intended to limit the invention to the described embodiments. On the contrary, it is intended to cover alternatives, modifications, and equivalents as defined by the appended claims. The following description makes full reference to the detailed features as outlined in the objects of the invention.

Referring now in detail to the drawings and in particular FIG.l thereof, therein illustrated is a schematic of one example showing how audio data is captured and processed according to one embodiment of the invention.

A wireless device such as a mobile phone or multimedia computer (101), or any suitable wireless or fixed network-linked device comprising a microphone (102) and audio data capture and storage and processing capability, captures part of an audio broadcast (103) such as a music broadcast. The broadcast audio data is recorded and stored by the device (101) and then compiled into a digital audio file (104) which is suitable for transmission and then transmitted over a fixed or wireless network and received by a digital audio data processing centre (105). The digital audio file (104) may also comprise data relating to the identity of the device, and or the time of the recording, and or the identity of the subscription holder of the audio data search service to facilitate sending the results of the audio data search process back to the person or device which initiated the audio data service request.

The received digital audio file (104) is then processed to generate a formatted data file (106) which is compatible with the format of the stored audio data digital archive (107) which forms part of the audio data processing centre (105). Upon receipt of the audio file (104), the identity data relating to the initiator of the audio search service are stored.

The formatted data file (106) is then processed into one or more search data files and then directly compared with data files stored in the audio data digital archive (107). In this way, if the audio data is stored within the archive (107) then the identity of the broadcast may be determined and transmitted back to the initiating device. In addition, the audio data search service may provide a direct link to a music purchase website and thus enable the consumer initiating the request, to not only learn the identity of the music broadcast but also to receive the direct means to purchase the identified music.

Now with reference to FIG.2 is shown a sequence of actions which describes how the audio data processing centre (105) performs the identification process upon a received audio dataset (104).

The audio data capture and search and identification process is performed in the following sequence of actions:

1. Device captures audio transmission

2. Received audio data is processed to create an audio dataset (104)

3. Dataset (104) is transmitted to a remote processing centre (105)

4. The audio dataset (104) is received and logged by the processing centre (105)

5. The received audio data (104) may be further processed into a number of datasets (106) to match the audio data stored in the audio archive (107) and or to facilitate an optimum search process

6. When a positive identification is made of the captured audio data, the identification is sent back to the person and or device which initiated the request.

7. Depending upon the application, the receiving device may be linked to a payment transaction service to purchase the broadcast, or the receiving device becomes enabled to perform an action such as open a door, activate a car park barrier or authenticate a cash withdrawal transaction.

In one embodiment the audio data digital archive (107) comprises a plurality of audio files σF wherein each audio file F in the archive is pre-processed into a set of files nF N where N refers to the unique identity of the dataset and where n refers to the identity of each part audio file within each audio file F N . Thus each nF N comprises a separate data file relating to a specific duration of the original total recording F N which may be further processed such that the correlation of the received dataset (104) with the stored format of data in a particular nF N is more quickly determined. It is anticipated that an optimised search engine function may be utilised such that each audio file stored in the archive may comprise a plurality of data files wherein each data file may be reduced to a limited or single data identity which is unique within the archive by a processing function f(x) and wherein a received dataset of captured audio data (104) is appropriately formatted into the format of the stored data (106) and processed according to the same function f(x) so that a direct 1: 1 comparison may be made between the captured dataset (104) and the data stored in the archive (107). In one embodiment, the capturing device such as the mobile phone or multimedia computer may comprise the capability to process the captured audio data using the same processing function f(x) such that the dataset may be more efficiently processed by the data processing server. To perform the audio data search identification service, the received and processed data file (106) will be searched within the archive. Each archived audio file F of identity N and of duration 1 " to tai may comprise a plurality n of data files where T tota i (N) = σnF N wherein each nF N is processed from a part audio dataset of duration Tp a n seconds of the total audio file and stored, wherein each part audio dataset starts t seconds after the previous recording such that Tpa rt is much greater than t so that any captured audio data which corresponds to a duration greater than T paιt and following processing into the appropriate format will comprise at least one processed part audio dataset stored in the archive.

In one embodiment, the separate audio data files nF N correspond to audio data of equal duration and where entry (n) is adjacent to entry (n+1) wherein each audio data file may only differ from the next adjacent file in audio data by a small amount such as a multiple of 10 milliseconds. This approach makes possible the processing of the received data (104) into a set of search files compatible with the stored audio data archive in a more efficient way. In an alternative embodiment, the received audio data file (104) is processed against each stored archive dataset F using a correlation method to determine a match between the processed audio file (106) and part of F wherein the received file (104) of duration t is cross correlated with each duration t within the total recording T of F in steps of s where s is much less than t which is much less than T. One can envisage the received audio data file (104) being moved along the digital file of F in steps of s and where the correlation of the file (104) is made between a part of the file F of duration t, equal in duration to the received data (104).

There is a direct application of this audio processing method and authentication of a person attempting to make use of a remote payment transaction service or other service using a mobile phone or multimedia computer or other device comprising audio capture and processing capability. In this application, actual words spoken by the person having legitimate access to the service are processed and transmitted for comparison with words stored remotely at the archive. In the instance of linking this method to cash withdrawal from an ATM or

bank cash point machine, the ATM payment withdrawal process is dependent upon receiving data from the said archive indicative of a successful match of the spoken words and audio data stored in the archive.

Other applications include voice-activated building access and or car park access. In other instances, the invention may be applied to provide building zone access to company personnel, and often inside buildings where network coverage is very poor or unavailable due to Faraday shielding effects. Employees make use of their mobile phone as the primary device and the incorporation of the mobile phone as a local service activation device correspondingly enables data capture using the mobile phone, processing according to access rights and activation of building automated doors using a local service activation capability.

It is anticipated that digital radio audio broadcasts and music broadcasts will evolve to comprise digital markers embedded within the broadcast and transmitted periodically such as every few seconds or at the start or end of a piece of music. It is further anticipated that these digital markers will generally be inaudible to the listener, or will be deliberately added to identify the music but render it of less quality than the purchased copy. Correspondingly, the capturing device need only capture one or more of these digital markers and transmit these to the remote audio processing centre for the audio broadcast to be identified.
