A live video rendering and broadcasting system.

FIELD OF THE INVENTION

The present invention relates to a live rendering and broadcasting system comprising a client system in communication with respective broadcasting servers, and especially to a rendering and broadcasting system wherein the client system is configured to provide and execute the rendering process.

BACKGROUND OF THE INVENTION

Broadcasting live television from venues and other types or similar arrangements like for example football or baseball matches etc. includes usually more than just a live video stream wherein a reporter is commenting on line in real time about episodes happening in a game for example. Mixing graphics with live video streams happens for example when updating a current status of a football game etc. before the video stream is broadcast, or for example is distributed to select end users over the Internet. Player statistics can also appear as graphics with text when for example a football player receives a red card from a referee. The additional text and/or graphics is usually mixed with the video stream before distribution of the content. The episode of a red card may be reported by for example a journalist writing a short notice of the incident before being converted and mixed with the video stream. Player statistics can be retrieved from a database maintained by the club the actual player is a member of, a third party data provider, etc. Prior art solutions requires that the journalist and respective data bases etc. is in communication with a video mixer or studio before distributing or broadcasting the video.

In general, contextually relevant content related or associated with a part of a multimedia content being rendered may be retrieved from one or more sources, and may be mapped to data associated with the portion of the multimedia data. The mapping results in the rendering of the relevant content during the rendering of the portion of the multimedia content and is providing contextually relevant data or information for the portion of the multimedia content being rendered. Usually, the mapping information is embedded in the multimedia content. An example of how a mapping can be achieved is disclosed in US 20130139209 A1 wherein an audio signal of the multimedia content is analyzed providing a sort of fingerprint related to respective section with specific multimedia content. When rendering the multimedia content, a system component will search for fingerprints and when a specific fingerprint is identified, a linking to associated graphics and/or data is identified and rendered together with the multimedia content of this specific portion linked via the specific fingerprint.

Live video streams may be distributed over Internet comprising graphics, and can be stored in user accessible server systems or in respective users' private computer systems etc. This enables an end user to scroll back and forth using a video player in communication over the Internet for example, or a video player application in a client accessing a computer server system storing video streams, for example from an Internet service provider, a TV station etc. The video application can for example be installed in a smart TV, in a computer system or in a hand held wireless device like a smart phone or a computer tablet etc. However, if the end user is interested in viewing once more a specific historical episode that happened during a game, prior art solutions provides no other means than rewinding and visually spotting when the episode appears in the stored video.

In general, the rendering of media content including graphics, audio, still images, video streams etc. provides a sequence of static objects on a display when broadcast as exemplified above, wherein interactive use of the media content by an end user is limited, and is usually limited to pre-programmed functionality embedded in respective video streams.

One aspect of interest are systems providing interactive television broadcasting over Internet.

US 6496981 B1 A discloses a system allowing media content to be used as an interactive media program comprising :

(a) media content in the form of successive image display frames indexed in a time sequence;

(b) object mapping data specifying the locations of objects appearing in the display of media content which are to be rendered interactive; (c) linkages provided through an associated interactive media program from the objects specified by the object mapping data to interactive functions to be performed upon selection of the objects in the display; and

(d) a user system for operating the interactive media program in conjunction with the display of the media content by selecting an object appearing in an image display frame and performing the interactive function linked thereto. The system includes an authoring system for generating the object mapping data for the media content. In a preferred interactive TV system, media content, in the form of movies, TV programs, advertising, and the like, can be presented as interactive media programs by transmitting the TV content with object mapping data ("hot spots") to a set top box connected to a viewer's TV. The TV set top box has a utility stored therein for performing the interactive functions linked to the defined hot spots in the TV content upon user selection. Interactive TV programs can also be presented using a conventional TV set top box and a remote control unit controlling the set top box. For example, if analogue video content is transmitted to the viewer on a channel provided by a cable TV company, then the object mapping data and program linkages for interactive functions can be transmitted in the video blanking intervals (VBI) interleaved with the video frames.

US 9330726 B1 discloses a mobile application enabling a first sporting event spectator to efficiently record game actions and a second sporting event spectator to simultaneously record real-time video of the game actions. Using a mobile device having a touch screen, the first user can efficiently, and with limited user interaction, indicate fast paced game actions of players engaged in a sport. Using a separate mobile device, or a video system in communication with a network, the second user can record video of a presently occurring game in which the game actions occur. A system in communication with the first and second users' devices can receive indications of game actions, and receive video of the game, and associate each indicated game action with a portion of the video of the game action. The system may for example, use these associations to generate an index that enables users to view descriptions of the game actions and jump to corresponding video clips.

In general, the different aspects of handling video rendering and distribution as discussed above includes mixing and integrating and identifying possible mappings of respective episodes with a multimedia portion related to a specific episode before distributing the multimedia content. Therefore, an end user has only a limited possibility of influencing what is displayed and distributed to him. Further, third party content may only be part of the video distribution if it is distributed to a facility providing mixing of multimedia data sources before distribution or broadcasting to end users.

Therefore, there is a need of an improved system providing more flexibility when rendering and distributing live video streams, and especially when streams includes multimedia content.

According to an aspect of the present invention, the rendering process including graphics, event data or data related to episodes, etc. is configured to be part of a client receiving separate streams of video and respective data from a supplier of respective video streams and data including third party suppliers of data of interest for a viewer, wherein the client is configured to provide visual presentations including video, text, graphics etc. ready for rendering by the client system.

OBJECT OF THE INVENTION

It is a further object of the present invention to provide an alternative to the prior art.

In particular, it may be seen as an object of the present invention to provide an improved interactive video rendering by configuring a client system to provide and execute rendering of respective video streams.

DETAILED DESCRIPTION OF AN EMBODIMENT

Although the present invention has been described in connection with the specified embodiments, it should not be construed as being in any way limited to the presented examples. The scope of the present invention is set out by the

accompanying claim set. In the context of the claims, the terms "comprising" or "comprises" do not exclude other possible elements or steps. Further, the mentioning of references such as "a" or "an" etc. should not be construed as excluding a plurality. The use of reference signs in the claims with respect to elements indicated in the figures shall also not be construed as limiting the scope of the invention.

Furthermore, individual features mentioned in different claims, may possibly be advantageously combined, and the mentioning of these features in different claims does not exclude that a combination of features is not possible and advantageous.

Figure 1 illustrates an example of a prior art broadcasting system referenced with the numeral 14. For comparison reasons, an example of embodiment of the present invention is also illustrated and referenced with the numeral 14'.

Traditional TV production receives video from respective cameras and/or from stored video sequences from other TV productions for example. In addition, text and graphics may also be included in the TV production. A TV production may be a live broadcasting from venues and other types or similar arrangements, for example football or baseball matches, concerts etc. Graphics and text in the video stream is also part of most TV productions. There exist some standards in the TV industry about how text for example may be introduced in the TV broadcasting. For example, "lower third" is defined as a graphic overlay placed in the title-safe lower area of the TV screen.

Enabling correlation and/or synchronization of respective video streams and graphics streams etc. is enabled by embedding for example a time code in the respective streams. Systems and/or apparatus processing video and data streams can then synchronize respective streams with each other based on the respective time codes.

In Figure 1 there is an example of a video production facility 13 that may be a standard TV studio, or a mobile TV studio, used for example at a football arena when a game is played, or any other type of equipment capable of preforming similar functions. Video capture system 17 may comprise multiple cameras located for example around an arena, and there may be journalist present at a game for example making oral and/or written comments about development and episodes happening during the game. In general, this is denoted data input 18.

With reference to Figure 1, video streams may be distributed from a traditional broadcasting system 14. The system 14 may comprise a prior art vision mixer 14a, which is a device used to select between several different video sources and in some cases composing (mixing) video sources together to create special visual effects in respective videos being broadcast to end users of the system. Audio can also be managed in a similar manner. It is also common to utilize a common universal time code for synchronizing respective video sources and video out signals generated by for example a broadcasting system 14.

The vision mixer 14a may receive graphics from a graphics control system 14b that communicate with a graphics storage system 14c, or is in direct contact with an operator generating and/or manipulating video graphics to be distributed with the output video streams.

At least one human operates normally the video production facility 13. The operator can select in real time which camera to be used and is monitoring data input 18 and decides via a video production equipment if for example text (or audio) should be embedded into the video stream.

It is important to understand that the video stream is made ready for rendering by the traditional broadcasting system 14 before submitted to end users TVs. Part of the rendering is to generate what is denoted as event data 15. For example, event data may comprise instructions sent to the graphics control system 14b instructing the controller 14b to fetch a text and/or stored graphic images from the graphics system 14c at a pre-set or given time code. Instructions at which time (time code) the text and/ or graphic images is be displayed or removed is also part of event data 15.

An external supplier may also supply event data 15 instead of being generated in the video production facility 13. External operators may follow a live broadcasting of a football match for example, and make instructions, create graphics and or text etc. A combination of graphics/text and external data 18 may for example be mixed by video production facility 13. The combined result can provide specific event data 15 identified in the video production facility 13, which can convert the event data 15 into instructions and/or data submitted to for example the graphics control system 14b of the traditional broadcaster 14.

According to an example of embodiment of the present system, 14' in Figure 1, the system 14' comprises a client 10, which is an apparatus that can be a home computer system operated by a user, or other devices like Ipads, smart phones, hand held wireless devices etc. A requirement is that the client 10 comprises a programmable computer system, or programmable device lOd configured by software to operate according to examples of embodiments of to the present invention. The client computer system lOd comprises an executable instance of software configuring the client computer system lOd to perform respective tasks according to respective aspects of the present invention. The software is

downloadable over Internet from a server system configured to supply the software according to the present invention.

The client 10 comprises further at least one display 10a, a video player 10b, a graphical user interface (UI) 10c, which is an integral part of the computer system lOd. The video player 10b may be a software program acting as a video player.

According to an aspect of the present invention, video streams and event data is distributed separately to the client 10 from the video production facility 13 in contrast to the prior art solution 14 as depicted in Figure 1. A separate video stream with time codes from the video production 13 is stored in a client video storage server system 12, and event data streams with time codes from the video production 13 is stored in an event storage server system 11. With reference to the description above, the event data may comprise external data 18.

It is important to note that the video production 13 is an optional part of the system. Any sources providing video streams with time codes and event data streams with time codes can be used with the respective event storage server system 11 and client video storage server system 12.

The executable software in the computer system lOd of the client 10 is configured to collect video and events from the individual client video storage server system 12 and the event storage server system 11. The rendering of video streams and fetching of event data is done by the configured software running in computer system lOd in the client 10. The programmable computer system lOd may be configured to start the video player 10b that can use a single time code or a series of specific timecodes to fetch video sequences from the client video storage server system 12. The same time codes can be used to fetch event data related to the current video sequence being rendered. More details is given below.

With reference to Figure 1, data input 16 in communication with the event storage system 11 may be used the same way the data input 18 of the video production facility 13 is used. Further, third party data providers may submit data to the event storage server system 11, for example via this data input 16. However, respective data streams should be embedded with a time code. In some instances, the event storage server system 11 may be configured to simulate or regenerate a time code embedded with the respective received data streams, for example based on time of arrival to the event storage server system.

One important aspect of the present invention is that event data are stateful data. "Stateful" in computer science means that a computer or program keeps track of the state of interactions, usually by setting values in a storage field designated for that purpose. Stateless means there is no record of previous interactions and each interaction request has to be handled based entirely on information that comes with the request. In the context of the present invention, stateful data comprises keeping values of parameters associated with events at every time code a parameter value is changed. For example, in a football match a score bug (which is a digital on-screen graphic displayed on a specific part of a TV screen during broadcast of a sporting event) can be "1-0" at a given time, which is associated with a first specific time code in the video. After a while, there is another scoring in the match. The

parameter score bug is then updated for example to "1-1" associated with a second time code. If the parameter score bug is treated as an ordinary parameter, the parameter value of the score bug will change from "1-0" to "1-1", and the

association between the first time code and the historical event of the "1-0" is lost from the event data. This is an example of stateless data. The event storage server system is configured to store the event comprising the score bug "1-0" associated with the first time code, and the event comprising the score bug "1-1" associated with the second time code.

This implies for example that a user, for example using the graphical user interface 10c of the computer system lOd can search backwords (or forward) in the event storage server system 11 for the event wherein the score bug is equal to for example "1-0". The parameter value of this event is associated with a specific time code (or an interval of specific time codes) as discussed above. This enables the client system 10 to fetch the time codes associated with the event "1-0", and use the time code or time code interval associated with the event to fetch out from the client video storage server system the video sequence comprising the situation wherein the scoring results in the score bug is "1-0". A further aspect of stateful data is that the example of using the graphical interface 10c to search for the specific score bug value is in itself an interaction that is kept stateful in the system. When searching backwards for example for a specific event in the video stream, the current viewing may be aborted by the user. This can also happen during a live broadcasting. The event of aborting the current viewing is recorded as an event and is also qualified with the user identity. That implies that this specific event is only related to the specific user even if it is stored in the event storage server system accessible by all users. When the user finishes viewing the video sequence comprising the "1-0" situation, this is a new stateful event and the state of his viewing is changed back to the video time code where the user aborted the current viewing. This is only possible since the data are stateful.

The technical effect of the example of embodiment of the present invention is a result of the architecture of the system comprising separating video streams from event data streams affecting or tailoring the rendering of respective video streams.

Therefore, the communication between the event storage server system 11 and a client computer system lOd comprises changing states, and the changing of states can be subject to further conditions, for example the user identity.

According to an aspect of the present invention there is a first state machine 1 configured in the event storage server system 11 in communication with a second state machine 2 configured in the computer system lOd of the client 10. State machine 1 in the event storage server system 11 is configured to handle inbound events from any source being part of a video stream being rendered in clients 10.

The state machine 2 is configured to enable a client 10 to determining which events from the state machine 1 is applicable for the client at a specific time.

The state machine 1 in the event storage server 11 is sending past and future events that are associated with the current time or clock in the client (time code). When a client 10 receives events it is guaranteed that the events are eligible to be executed in a respective client. However, this does not imply that an event is applicable to be executed in the context of a specific client. The state machine 2 configured in the client computer system lOd determines if the event is applicable to be executed in the specific client 10. Verified events are then executed by the state machine 2 when a defined timecode parameter value of the event matches against the current time in the client. Refer Figure 8 and Figure 9 for more details.

It is important to have in mind that a source can be a video production facility that may include human control of the production of video streams. In addition respective clients can modify for example information being viewed on their own display. Events can be unique for each client and a client can receive events from the event storage server system 11 and also create and send events to the event storage server system 11. Further details is given below.

A client 10 is further configured to update the visual presentation including graphics that may be included in the received stateful data when new events, or changes is identified in existing displayed events as recorded in the requested stateful event data from the event storage server system.

The event storage server system 11 is further configured to create a common data format of respective received data with a time code. The common data format is adapted to the client 10 that can read out event data.

The client 10 do not need to receive all event data and complete video streams of a specific video. Instead, the video player can use the time code to fetch event data one at a time correlated with the time code together with video images one at a time from the client video storage server system. Based on stateful event data, information and/or instructions, and/or user interaction via the graphical user interface (UI) 10c, the client system is further configured to create a visual presentation including graphics that may be comprised in the received stateful data of a current state based on the current time code in the video.

Figure 2 illustrates the example of embodiment of the present invention illustrated in Figure 1, but without the example of a prior art solution present.

A video production facility 13 receives live video and contextual relevant data. Based on these streams, the video production facility 13 is distributing video to at least one client video storage system 12 and event data based at least on the contextual relevant data 17a is distributed to an event storage server system 11. The video production facility 13 is optional. An alternative is that the client video storage server system is configured to receive video streams directly, and may be configured with a front end implemented vision mixer. Such a vision mixer may be controlled by a robot that also can be implemented in the video client storage server system 12. Event data 17a, data input 16, third party data 16a may be supplied by at least one external source as discussed above.

In an example of embodiment of the present invention, the event storage server system 11 is configured to create a common data format comprising a subset of consecutive time codes. Such a data item is denoted a timeslot and is correlated with the time codes. In this respect, a timeslot may comprise more than one event.

In an example of embodiment of the present system, the client 10 processes one timeslot after the other.

Figure 3 illustrates an example comprising three timeslots. At the bottom it is illustrated how respective data inputs 30, 30a, 30b and 30c is in communication with data translators 31a, 31b, 31c translating data thereby making it possible to create a common data format 31.

In the example disclosed in Figure 3, a first state machine 32 is configured in the event storage server system 11 being in bidirectional communication with a second state machine being configured in the client computer system lOd.

There is a client/server communication component 33 in the system interconnecting signalling between the first and second state machine.

An example of a generic process flow in a state machine is disclosed in Figure 6 discussed below.

When a client 10 is processing a timeslot, event data is processed. In timeslot 1 (reference numeral 35) in Figure 3, a parameter "lower third" is set to a state displaying the content of the "lower third" parameter by the command "show" at a first timecode point in timeslot 1. At a later timecode point in timeslot 1, another command "hide" will hide the content of the "lower third" parameter from being displayed. Another parameter "Score bug" is set to a state displaying the content of the parameter "Score bug" by the command "show". In the second timeslot 2 (reference numeral 36) the parameter "lower third" is set to state "hide". At a later timecode point, the parameter "Score bug" is set to an updated state by the command

"update". At a later timecode point, a table is set to state "Show", i.e. being displayed.

In a third timeslot 3 (reference numeral 37) the parameter "lower third" is set to state "show", then to "hide" and parameter "Score bug" is set to state "update".

The respective states are changed by signalling from the second state machine 34 configured in the client 10. Respective signals that cause the second state machine to change state stems from at least two sources. One source is the event data received from for example a video production facility 13, or an external supplier of data. The first state machine is configured to signal the second state machine when states changes. A second source is the second state machine in the client 10, which is configured to receive input via the user interface layer (UI) 10c configured and executed in the client computer system lOd. The graphical interface layer 10c is configured to signal the second state machine to change at least one state.

In addition, the event storage server system 11 is configured to create stateful data and store historical stateful data. Therefore, the second state machine may signal the first state machine of such state changes and record them in the server. All these actions are correlated with the time code that drives the rendering forward when the video player 10b issues time codes to the video storage server system 12 and the event storage server system 11.

Figure 4 illustrates how different states A, B, C, D may appear in different timeslots, both historical timeslots, i.e. timeslots that has been processed or rendered as well as future timeslots to be rendered. In the lower part of Figure 4, it is indicated a current client time code point (for example a timecode from the video player). The client 10 receives the timeslot and relevant historical events from previous timeslots in addition to current events are processed. Figure 5 illustrates a similar situation. Figure 6 illustrates an example of process flow in an example of a second state machine according to the present invention. At a current code point a new process starts. The first test is to identify if the requested timeslot is already downloaded or not. If not, the timeslot is requested by the second time machine. Then a test if historical events are to be executed within this timeslot is performed. Then a rendering of all events starts in this timeslot.

Below is an example of code of an event. Clock#show describe that the clock is starting. In this example, a unix timestamp is used. The timestamp gives the number of seconds from 1 January 1970. PlayByPlay#show disclose a free throw in a football match.

Figure 7 illustrates a first and a second client 10 receiving video streams from an external source. The external source may be video streams from a video production facility 13, or any other source as discussed above.

The client 1 and client 2 is in communication with a common event storage server system 11.

Video streams and event data is presented at the same time to a client 10 at a same time. A user of the first client 1 and a user of the second client 2 may both have started streaming a same video or different videos. The time of presenting the videos and event data to the first client 1 and the second client 2 can be different since it is the time code issued by the respective first client 1 and the second client 2 that drives the rendering locally in each respective client.

The video streams and event data are synchronized by a shared time reference, for example a universal time code from a video production facility. Then the recorded time codes on respective servers can be synchronized.

A client will receive state parameters from the event storage server 11. Events and state parameters is processed with time synchronization by the client computer system lOd. The client computer system lOd is then configured to render correct presentations of events in live or historic settings.

The aspect of using a user identity as part of events enables a first user of the first client 1 to make his own unique presentation via his own graphical user interface 10c compared to a second user of the second client 2 even if they are viewing the same video stream.

The example of embodiment of the present invention disclosed above uses state parameters comprising a set of values describing an event. Here is a non-limiting example:

• An event executes at time reference.

• An event terminates at time reference.

• Condition: Phone only, i.e. a smart phone is the only allowed device a user can utilize when viewing videos.

• Condition : Norway, i.e. a user can only view the displayed content in Norway.

• An event has been executed at time reference.

• An event has been terminated at time reference.

The first client 1 and second client 2 can receive and send events (set respective event parameters describing an event) to the event server 11.

The event server 11 is configured to organise and store received events including storing events with at least time codes.

Events are distributed from the event server 11 to the firs client 1 and the second client 2. Figure 8 illustrates an example of process flow of an event. The device is at a current time code of 10 seconds into the video. The device is a phone and the location is Norway. The client may for example request events from the event server 11. A table comprising event identity (event ID) and a list of time codes associated with the respective event IDs. The action to be performed is also listed and rules. For example a rule is that an event ID is associated with the location Norway, which indicate that the action of the event can only be executed in Norway.

Any event requested is filtered based on rules determining if the events are applicable for the specific client. The client ID (not illustrated) is also part of events as discussed above.

The result of the filtering result in an event list comprising event ID 1, 3 and 5 as illustrated in Figure 8.

The next step is to verify which events are qualified by the time code to be executed. This is a new filtering process based on the time code specified for the respective events.

The result is that events with the event ID 1 and 3 are qualified to be rendered. One feature is that the time code may be used to adjust event parameter values.

Figure 9 illustrates the flow of timecodes and eventsin a client 10 like the operations illustrated in Figure 8. The input parameter in Figure 9 is a timeslot (a collection of consecutive time codes). The first test is to verify if the timeslot already is

downloaded or not. If the timeslot is downloaded the timeslot is active (i.e. execute event parameters at respective time codes of the timeslot). If the timeslot is not downloaded the timeslot is requested. The next step is to qualify the event by filtering the event as disclosed in Figure 8. The output of the process is a list of qualified events.

Figure 10 illustrate a situation wherein a producer creates a poll event (i.e.

submitting questions to viewers and is collecting answers. A poll event is stored in the event storage server system 11. A first client is located in USA, and second client is located in Spain and a third client is located in Germany. The poll event for USA will then have an event parameter identifying USA and the language used for the questions and answers from the client will automatically be submitted and received in English. The same applies for the events for Spain and Germany that will respectively be submitted and received in Spanish and German. The response from each client is sent back to the event server from each respective client creating an event.

Another example is illustrated in Figure 11. A producer creates and event and send the event to the event storage server 11. The event storage server 11 is configured to package and format the event that can be distributed individually and b globally to connected viewer devices (i.e. clients 10). Whenever a new viewer is connected, the event is sent to this device as well.

Figure 12 illustrate respective timelines of a football match between France and England. There is a clock for the match itself (two periods of 45 minutes each), video stream timeline and a timeline for the events, for example, events describing the scorebug as discussed above.

It is further within the scope of the present invention to implement the first state machine and the second state machine as state machines comprising more than one state machine.
