- a user is viewing a television program on the first client device 14 which is a television.
- This program is broadcast continuously by the first server 10 in a data stream TS comprising DVB-SI tables.
- the user has a second client device 16 which is a virtual reality headset.
- the decoder device 13 and the second client 16 are able to communicate using a protocol of the RPC type (call of a remote procedure, "Remote Procedure Call” in English terminology) such as JSON-RPC (object notation). in JavaScript, "JavaScript Object Notation”) or XML-RPC (Extensible Markup Language), which allows you to simply exchange commands and structured information.
- the processing module 131 therefore implements an RPC server and the processing module 161 implements an RPC client.
- the processing module 131 of the decoder device 13 detects and extracts from the data stream TS comprising the television program being broadcast on the television 14 information representative of the additional content.
- the information representative of the additional content is in the form of a DVB-SI table comprising information of the HbbTV type.
- the HbbTV type information indicates that additional content is available and indicates at least the address of the second server 15.
- the processing module 131 provides the user, via the television 14, a signal, said information signal, indicating that it is possible to obtain the additional content.
- the processing module 131 triggers a display on the television 14 of an icon that the user identifies as a signal indicating that additional content is available.
- the information signal is a sound signal that the user identifies as a signal indicating that additional content is available.
- the user launches an application on the virtual reality headset 301. This application is implemented by the processing module 161 and implements a client RPC .
- the processing module 161 causes a transmission by the client RPC that it implements a connection request to the RPC server implemented by the processing module 131.
- the RPC server implemented by the processing module 131 receives the connection request and accepts it.
- the processing module 161 causes the sending by the client
- RPC implements a request, said information request, the RPC server implemented by the processing module 131 to obtain information on the additional content.
- the RPC server implemented by the processing module 131 receives the information request.
- the RPC server implemented by the processing module 131 transmits said information on the additional content to the RPC client implemented by the processing module 161.
- This information comprises at least the address of the second server 15.
- the implemented RPC server by the processing module 131 knows moreover what television program is broadcast by the decoder device and knows moreover which table DVB-SI has caused the transmission of the information signal.
- the additional content information further comprises an identifier of the television program and an identifier of the DVB-SI table having caused the information signal to be transmitted.
- the RPC client implemented by the processing module 161 receives said information on the additional content.
- a step 309 upon receipt of the information request, the processing module 131 pauses the supply of at least one component of the television program at least as long as a request, said final request, indicating an end of use of the additional content is not received by the decoder device 13 from the virtual reality headset 16.
- One of the components of the television program is for example a video component transported in a sub-stream of compressed video data, an audio component transported by a substream of compressed audio data or a subtitle component carried by a sub stream of data subtitles.
- the entire television program is paused upon receipt of the request for information, ie all components of the television program.
- the television 14 therefore no longer displays the television program as long as the user uses the additional content.
- the processing module 161 implements steps 310, 313, 314 and 315 allowing it to use the additional content.
- the processing module 161 transmits a request for obtaining the additional content to the second server 15, for example in the form of an HTTP request (hypertext transport protocol, "Hypertext Transport Protocol" in English terminology), using the address of the second server 15.
- this request for obtaining includes the identifier of the television program being broadcast on the television 14 and the identifier of the DVB-SI table having caused the transmission of the information signal. These two identifiers allow the processing module 161 to indicate precisely to the second server 15 which additional content to return. It is assumed, in fact, that in this embodiment the second server 15 comprises a table matching each additional content that it stores with a TV program identifier and a DVB-SI table identifier. However, the request for obtaining the additional content may not include an identifier when, for example, the second server 15 includes only additional content.
- the second server 15 receives the request for obtaining the additional content.
- the second server 15 transmits the additional content corresponding to the identifier of the television program and the identifier of the DVB-SI table received in the additional content request to the processing module 161.
- step 313 the processing module 161 uses the additional content following its reception.
- the additional content is a virtual reality application representing a scene or a virtual world. The user then uses his virtual reality headset 16 to walk in this scene.
- step 314 the user terminates the use of the additional content. For example, he removes his virtual reality headset.
- step 315 the client RPC implemented by the processing module 161 transmits a final request indicating the end of the use of the additional multimedia content to the RPC server implemented by the processing module 131. Said final request is able to cause an action of the processing module 131 involving the television 14.
- a step 316 the RPC server of the processing module 131 of the decoder device 13 receives the final request.
- the action caused by the reception of the final request by the processing module 131 consists in restarting the supply of each component of the first program television broadcast paused in step 309 on the television 14. The broadcast of the television program then resumes on the television 14.
- the virtual reality application is an MPEG-4 (ISO / IEC 14496) or Web M (https: // www. Webmproj cct.org/) video stream combined with metadata of a spherical video.
- Spherical Video V2 RFC https://github.com/googlc/ spatial-media / blob / master / docs / spherical-video-v2-rfc .md
- the processing module 161 must implement a video player capable of decoding this type of stream and take into account this spatialization information to correctly display the application taking into account in particular the movements of the virtual reality headset 16.
- the virtual reality application is an interactive application such as for example a game application.
- the user plays the game that is proposed to him and obtains a score (i.e. an interaction result).
- the action caused by the receipt of the final request by the processing module 131 then depends on the score obtained.
- the user can switch to another television program included in the data stream TS instead of the initial television program. Otherwise, the user does not change television program.
- a new component of the television program is provided to the user.
- the RPC client implemented by the processing module 161 transmits the score obtained by the user to the RPC server implemented by the processing module 131.
- the processing module 131 receives the score and decides on an action based on said score.
- the virtual reality application is customized according to the television program.
- the television program is a football game broadcast in real time ("live" in English terminology).
- the virtual reality app is a three-dimensional animation depicting a football match. In this animation, it is possible to customize jerseys of the players of each team.
- the virtual reality headset 16 then receives the virtual reality application in a non-personalized form and customizes it according to information on the television program provided by the decoder device 13. This information is for example extracted from fields EIT (Event Information Table) of DVB-SI tables included in the TS data stream.
- EIT Event Information Table
- the additional content is a soundtrack in a language different from the language used until then during the broadcast of the television program.
- the second client device 16 is for example a smart phone.
- the processing module 131 upon receipt of the information request, the processing module 131 causes the supply to the television 14 of the original audio component to be paused.
- the supply of the video component of the television program as for it is not interrupted and this component is always displayed continuously by the television 14. From this moment, the television 14 no longer broadcasts the original soundtrack of the television program, but only the video component of the television program.
- the smartphone 16 broadcasts the additional content corresponding to a new soundtrack.
- the processing module 313 causes the restart of the supply of the audio component corresponding to the original soundtrack.
- the processing module 131 has stored the television program during the use of the additional content and that in the step 317, when the processing module 131 restarts the provision of each component of the first program television paused in step 309, it resumes the supply of each component from the moment of pause. In this way, the user does not miss any part of the television program during the pause of this one.
- Fig. 4 schematically illustrates a second example of a combined broadcast method of a television program and additional multimedia content according to the invention.
- the system 1 comprises two second client devices 16A and 16B identical to the client device 16.
- the second client device 16A includes a processing module 161A and the second client device 16B comprises a processing module 161B.
- the processing modules 161A and 161B are identical to the processing module 161.
- Step 300 of FIG. 4 is identical to step 300 of FIG. 3.
- Steps 301A to 316A are identical to steps 301 to 316, respectively.
- Steps 301B to 308B and steps 310B to 317B are identical to steps 301 to 308 and 310 to 317, respectively.
- Step 309 A is different from step 309. Indeed, when several second client devices are connected to the decoder device 13, only the first information request received from a second connected client device must cause the pausing of the provision of at least one component of the television program.
- the step 317B is different from the step 317. Indeed, the action of the processing module 131 involving the television 14 can be caused only by the reception of the last final request. In other words, it is necessary that the processing module has received as many final requests as requests for information to cause said action.
