Definitions
- Multimedia flow means a set of digital data that makes up graphic, audio, audiovisual, and other environments.
- the present invention relates more particularly to the management of interactivity services that are linked to such multimedia streams.
- PCT application WO2008 / 030298 discloses mechanisms for managing interactivity.
- This application describes a system and a method for voting via an interactive television system.
- this patent application describes the possibility of integrating an interactivity request into a metadata stream as part of the TV via ADSL. It also describes the interaction with the user and the processing of the user's answer (his vote).
- Digital content may be for example a television program, a film, a radio program, a musical title, etc.
- Media streams carrying digital content include several types of data: video, audio, and metadata.
- a metadata is by definition a datum used to define or describe another datum.
- an audio type metadata may contain a song or album title, a duration, an interpreter, and so on.
- Interactivity queries that are inserted into the metadata allow interaction with the end user through messages or data exchanged with devices specifically designed for that purpose.
- the invention does not have the drawbacks of the prior art.
- the invention is in the form of an interactivity management system between a broadcast platform of a content provider and a user terminal.
- such a system comprises: a content broadcasting platform comprising means for broadcasting a content to said user terminal, said content comprising metadata associated therewith; at least one user terminal, comprising means for receiving said content from said broadcast platform and means for extracting at least one interactivity request previously inserted in said metadata and transmission means of a response to said interactivity request.
- the invention makes it possible to transmit only the response data to the interactivity requests.
- the extraction by the terminal of the interactivity request ensures that it will be processed independently of the content with which it is associated.
- the response to the interactivity request is therefore issued independently of the content that contained the request.
- the content is therefore not reissued and only the data needed to process the response or possibly the data necessary to initialize a dialogue with the terminal are issued.
- the invention therefore greatly simplifies the management of this type of interactivity request while providing an opening to other platforms, such as the platforms of the broadcasters, so that they can process the interactivity data that interests them.
- said system further comprises an intermediation platform (104) comprising means for receiving said response from said terminal (103).
- An object of the invention is a content broadcasting platform of a broadcaster comprising means for broadcasting (101, 102) content to a user terminal, said content comprising metadata associated with it, at least an interactivity request having been inserted, prior to the broadcasting of said content, within said metadata.
- said content distribution platform further comprises: means for creating a token making it possible to identify said interactivity request; means for inserting said token within said interactivity request; means for inserting said interactivity request into said metadata.
- the broadcaster can itself insert its own interactivity requests, according to a standard insertion protocol. The broadcaster is therefore free to conduct surveys, polls, votes, etc. that it wishes without it being dependent on the technical architectures of the networks of diffusion.
- Another object of the invention is a user terminal comprising means for extracting at least one inserted interactivity request, prior to the broadcast of a content, within metadata, said content comprising said metadata which are associated with it.
- the user terminal further comprises:
- Means for transmitting a response to said interactivity request Means for transmitting a response to said interactivity request.
- said user terminal further comprises: means for processing said extracted interactivity request delivering at least one processing result; insertion means, within said interactivity request, of said at least one result; means for transmitting, to said intermediation platform, said response relating to said processed interactivity request, in the form of a request completed by said response.
- the invention enables the terminal to process the interactivity request, for example in relation to choices made by the user through an interface and to transmit the results directly to the intermediation platform.
- the results of the processes are inserted within the interactivity request itself by using one or more fields intended for the transmission of the response.
- said intermediation platform comprises: means for analyzing said completed interactivity request making it possible to identify, using said token, said broadcaster and said user terminal; means for processing invalid requests for tracing said completed request when it has an anomaly; processing scheduling means related to said completed request; means for recording queries for identifying and saving said completed query for later use; means for activating actions that are performed by said intermediation platform according to a nature of said completed request; processing means which retrieve said at least one result contained in said completed request, and perform specific processing of these results to constitute data to be made available; provisioning means responsible for supplying the content provider with said data to be made available.
- the intermediation platform makes it possible to centrally and openly handle the responses to interactivity requests.
- the invention also relates to a method for managing interactivity data broadcast by a content distribution platform of a broadcaster in a user terminal comprising: a step of receiving content from said broadcast platform, said content comprising metadata associated with it: a step of extracting an interactivity request inserted, prior to their distribution, within said metadata; a step of transmitting a response to said interactivity request.
- Another aspect of the invention relates to a computer program product downloadable from a communication network and / or recorded on a computer-readable and / or executable medium by a processor, including program code instructions for implementation. the data transmission method as described above.
- the invention also relates to a method of transmitting interactivity data between a content provider and a user.
- such a method comprises: a step of broadcasting content to said user said content including metadata associated therewith; a step of receiving said content from said broadcaster: a step of extracting an interactivity request previously inserted within said metadata; a step of transmitting a response to said interactivity request; a step of receiving a response to said interactivity request from said terminal.
- the invention also relates to data accompanying a content broadcast by a content provider.
- data comprise an interactivity request comprising: a request start tag making it possible to identify that it is interactivity data; a token for identifying said content broadcaster; an action code making it possible to identify the type of action requested by said interactivity request, said action code comprising at least one field intended to receive a response to said interactivity request; an end tag to identify the end of the interactivity tag.
- the invention makes it possible to simply define an interactivity request that is inserted within the metadata that accompanies a content included in a multimedia stream and authorizes the formulation of a response to this request within the interactivity request itself.
- the multimedia stream is transmitted by the content broadcaster. It therefore also inserts the interactivity query in the metadata of the stream.
- FIG. 1 presents a block diagram of the system of the invention
- FIG. 2 illustrates the support of an interactivity request within a client terminal
- FIG. 3 illustrates the support of an interactivity request containing a response within the intermediation platform
- FIG. 4 illustrates a use case of an implementation of a system of the invention.
- the invention proposes an open system enabling the providers to efficiently manage interactivity data of which they are the initiators.
- the invention makes it possible to propose a new solution for the implementation of interactivity, through mechanisms for exchanging so-called interactivity requests between client terminals and broadcasters.
- the solution of the invention allows: the content provider can be directly behind the interactivity request, integrate it directly into the metadata of the stream that it broadcasts and forward it directly to the end user, without one third is in denomination; the interactivity request can be broadcast from the broadcaster to the end client terminal, on a network or a type of network different from that used by the response to the request (ex: request in a metadata stream broadcast in digital terrestrial and response routed via Internet, integrated query in a stream traversing a specific virtual channel and response via another virtual channel); the request can be generated dynamically, when broadcasting a live stream, or in static mode when generating recorded content (eg DVD, Video on Demand); the query and the interactivity response can be generated respectively
- the invention is structured around an intermediation platform.
- An intermediation platform makes it possible to manage the data exchanges between the different third parties: it makes it possible to receive data from the users' terminals, to process or concatenate these data, to archive them or to transmit them to the content providers. and / or service providers.
- the interactivity data is, according to the invention, integrated within the metadata that is transported with the streams.
- multimedia streams audio, video
- These metadata which are used for purposes of identifying the contents of the streams or for the purpose of setting the parameters of the rendering of the streams are, according to the invention, used to transport the interactivity requests.
- the interactivity data can be integrated within description metadata or stream synchronization, depending of course on the coding standard considered.
- the interactivity data can be integrated within the synchronization stream.
- interactivity requests are formatted according to a specific formalism which makes it possible to define an exchange protocol (see example of exchange protocol).
- interactivity requests contain a token, created by the content provider.
- This token allows the content provider to effectively manage the requests it sends to the terminals.
- the token which is used by the content provider to identify each interactivity request, is unique and unique to the content provider in question. To do this, such a token comprises an identifier, preferably unique, of the content provider, a set of identifiers specific to each request and interactivity parameters, specific to the query in question.
- the token also includes a response time. This response time is used by the intermediation platform to determine a time beyond which the token is no longer active. In other words, I token serves as a time marker for interactivity data.
- the token that accompanies the multimedia stream includes a basic question "Do you like this program? ".
- the token then comprises a temporal indicator of end of survey which makes it possible to define a time from which a response will not be taken into account. This temporal indicator will then be used by the intermediation platform to determine from when aggregation and / or correlation processing should be initiated (the end of the probing period).
- the response or responses to the interactivity request received by a terminal are inserted in the interactivity request itself, which is in some way completed by the terminal before being transmitted to the intermediation platform for processing.
- Responses to an interactivity request can be inserted automatically by the terminal when the request does not require the intervention of the user. In this case the user does not know that the terminal performs this type of processing (it is typically an audience measurement of a program).
- These answers can also be inserted according to the responses or behaviors of the user facing the interactivity request.
- the invention thus proposes an open system which, thanks to the intermediation platform, a simple protocol and the use of existing metadata, allows other service providers and content providers to interact directly with the users and to obtain information does not from these.
- the invention therefore solves a problem of size in this type of system. Indeed, as already mentioned, the prior art broadcasting systems are partitioned and do not allow the content provider to have knowledge of actions or operations performed by users.
- the invention naturally finds its place in applications such as: measurement of audiometry: there is in this case no interactivity with the user, the terminal acts on its own to respond to the request of the provider content ; - polls, votes, games;
- a phone call can be implemented (Click-to-call); Documentation can be sent by mail or mail; According to the invention, only the intermediation platform knows the terminal correspondence / user account and is able to preserve the identity of the client; The purchase of a product or service;
- Audio / video "hook-up" temporary or permanent switchover to another source of content (eg IP Radio or Digital Terrestrial Radio).
- Divert to a service The interactivity data of the broadcast stream contains a link to another service (any priori). This service addresses the terminal in question or equipment connected to it.
- the system that implements the method of the invention comprises a content provider 100.
- This content provider encodes and broadcasts the stream through an encoding platform 101 and a streaming platform 102
- the stream is broadcast to a client terminal 103 which, on the one hand, carries out the operations necessary for decoding and restoring the stream and, on the other hand, the processing operations of the interactivity requests.
- These processing operations provide results which are transmitted, via a communication network, to an intermediation platform 104 which is responsible for storing the results of the processing operations and possibly carrying out additional processing operations itself.
- the intermediation platform 104 then makes available to the content provider 100 the results of the interactivity requests that it has stored.
- the intermediation platform 104 also interacts with other service platforms (105, 106, 107). These platforms can be online sales platforms, platforms for implementing specific devices available to the user, etc. It is important to note that, according to the invention, it is not necessary for the results of the interactivity request to be transmitted to the intermediation platform 104 by the same communication network as that used for the reception of the request. request by the client terminal 103.
- the interactivity request can be transmitted via the radio or satellite digital broadcasting network (the uniqueness of the token then depends solely on the content provider) and the response to this request can be transmitted. through an xDSL network.
- the metadata stream containing the token can be transmitted independently of the multimedia streams to be restored, for example by using the xDSL network to which the client terminal is connected.
- a flow management method is presented allowing interactivity such that it can be implemented within a terminal, for example an audio and / or video reproduction terminal.
- a multimedia (MS) stream contains audio and / or video (S) media streams and interactivity data (I).
- This MS stream is created by a content provider.
- the stream MS is received (1) by the terminal, it is decoded (MS) and the audio / video content (S) is returned (2) to the user (U) via a suitable device (DpIy) .
- the interactivity data (I) is sent (3) for decoding and processing to the metadata decoding module (MD).
- This metadata decoding module (MD) inspects the data and returns (4) to the user if it is conventional metadata, otherwise it sends (5) (after extraction) to the management module of the interactivity (MI).
- the interactivity management module processes, according to the invention, the interactivity request in accordance with the planned actions and the defined protocol (see protocol and use case).
- the module "Presentation &order" (C) to interact with the user (LJ) by displaying messages (7) and waiting for answers (8), if necessary, for example if the request for interactivity contains data and / or messages to be displayed to the user the intermediation platform (P), to which he is connected, to trace a result or request authorization before triggering an action or a sequence of actions (9) according to the token or chips contained in the interactivity data of the request.
- the capabilities of the terminal or other equipment (E) connected (10) wired or wireless to the terminal see protocol and use case) for a particular implementation.
- an interactivity management method is presented such that it can be implemented within an intermediation platform of the invention.
- the intermediation platform (P) is the platform to which the interactivity module (MI) of the terminal described in FIG. 2 is connected.
- This intermediation platform comprises several modules: a module for receiving requests and responses (MRR) from the users'terminals; a module for analyzing these requests (MAR); an invalid request processing mold (MTRI), module arranged in such a way that any invalid request can be immediately communicated to it, without analysis, in order to reduce the risks related to security vulnerabilities; a scheduling module for processing related to the responses / requests (MOR); a request recording module (MER) allowing their identifications and their backups for later use; an action activation module (MAA) that is carried out by the intermediation platform; processing modules (MTx) that retrieve the responses, and perform the specific processing of these responses to constitute data to be made available; a provisioning module (MMD) responsible for providing the content provider with previously processed data, such as voting data or statistical data.
- MRR requests and responses
- MAR invalid request processing mold
- MTRI invalid request processing mold
- the request reception module receives (11) requests from the terminals, which it can perform authentication prior to the passage (12) of the requests to the analysis module (MAR). In both cases, it enriches the requests with the identity of the terminal and the date / time of reception.
- the module of analysis of the requests (MAR) checks the good formalism of these and if necessary authenticates them by using for example an electronic signature conveyed in the transmitted data (with the field "token” in the example of protocol). If the request is subject to authorization by the intermediation platform (see “action authorization T" of the example protocol), an acknowledgment is sent back to the terminal via the request reception module (RRM). .
- the request is subject to authorization by a third party (see “action authorization” 2 '"of the sample protocol), for example to check the subscription to a service, it is contacted in" B2B "mode (from business-to-business English) (14) to a platform located on an NTWK network after retrieving (13) external terminal / user correspondence data from the authentication system located on the NTWK network (or other network , not shown). An acknowledgment is then sent back to the terminal.
- action authorization 2 '"of the sample protocol
- mode from business-to-business English
- MTRI invalid request processing module
- the request is valid, it is transmitted (17) to the request registration module (MER) which, prior to the data recording, verifies the uniqueness of the request thanks in particular to the identity of the terminal.
- MER request registration module
- a return code is returned to the query analysis module (MAR). This return code has three states:
- the request is invalid, it is logged (15) by the invalid request processing module (MTRI); - New token (see protocol):
- the request analysis module (MAR) prevents (16) the processing scheduling module (MOR) which is in charge of scheduling the processing.
- the action activation module (MAA) triggers
- the processing scheduling module activates (21) the processing of the responses by implementing one or more processing modules (MTx).
- a processing module retrieves (22) the set of responses, correlates them according to the action code used and possibly by relying (23) on external data of terminal / user correspondence and of user / profile type (DE) .
- the aggregated and correlated data is transmitted (24) to the Data Provisioning Module (MMD).
- This data delivery module can transmit (25) these correlated and / or aggregated to a person or a machine defined by the diffuser of the request, that is to say the content provider.
- the provision of data can also wait for the recipient to come for these data, in which case the intermediation platform can offer different or complementary processing requests.
- the interactivity data that is inserted into the metadata of the stream are coded according to a particular protocol making it possible to process the requests and the answers formulated in a simpler and more efficient manner.
- the structure of the interactivity data can for example be the following: ⁇ start tag> ⁇ token> ⁇ action code> ⁇ action authorization> ⁇ validity period> [parameter]
- the interactivity data structure is created using tags. Allowing to delimit, in a tree way, the set of interactivity data. The meaning of the fields is described later:
- action codes makes it possible to define standard actions that can be understood by all terminals. It also makes it possible to define private codes introducing sub-protocols only understandable by certain terminals or equipment connected to these terminals (wired or wireless).
- Measurement of audiometry (order no .: 128, action code '7', no authorization '0', 900 s of delay):
- Metadata received by the terminal INTER OAc 129 2 0 300 "If you agree Type 7 'otherwise' 2 '" ACTIVE; Data returned to the intermediary: OAc 129 2 300 0 1 (it is assumed that the user has typed the key 7 ');
- This single token can be composed on the one hand of an identifier of the broadcaster, a user identifier and other related data.
- a first content is dedicated to a first user and a second content is dedicated to a second user. It is possible, according to the invention, to respectively generate a first interactivity request, then a second interactivity request respectively to the first and second users. It is thus easier to plot the answers for each of these users according to these unique tokens.
- Such an implementation may be of interest for example in the case of broadcasting "podcasts" or broadcast on demand that are made in unicast and not at the same time. This variant is presented for illustrative purposes, because it is also possible to use an identical token for all customers (even in unicast), and to use the identifier of the terminal, to individualize the customer's response. .
- the interactivity request in the broadcast stream contains a link to another interactivity broadcasting source.
- the module (C) opens a second connection to the site identified by this URL to retrieve the interactivity data in order to reinject them into the interactivity management module (IM) or to a user. equipment connected to the terminal.
- the authentication of the terminal and the verification of the access rights to the service can be performed on the intermediation platform, for example by using a B2B link with the partner, the latter returning the access data to be communicated. to the terminal so that it can connect to the platform for providing interactivity.
- This second connection can be done in multicast but also in unicast, in which case the platform for providing interactivity is able to serve interactivity data customized or related to a group of users.
- This connection is also bidirectional and allows direct interactivity between terminals or devices connected to them.
- authorization action '2' For example, for the animation of a device connected to the terminal (action code '123') requiring the agreement and the provision of access data by a third party, authorization action '2'):
- the intermediation platform retrieves the terminal / user association data and then requests the agreement and access data from the third party (http://www.lesite.com/1287947Qf565Rh6fg6). She can then reply to the terminal:
- the site verifies the access rights before serving the data
- the broadcaster may associate with other third party services to allow the implementation of additional service or equipment.
- a user (U) listens on an audio terminal (TA) bearing the serial number "123", an audio stream (FIA) broadcast by a radio R having a platform PR.
- the audio stream is broadcast either via an IP network or via a terrestrial radio network (Digital Terrestrial Radio).
- the stream streamed by the radio R includes audio data and metadata (including the interactivity request identified with the token 001 of the purchase type of the title broadcast on the shop online purchase Z with a prepaid account).
- the audio terminal (TA) first proceeds to a decoding 40 of the audio stream which is reproduced in sound form (via a HiFi system or other suitable equipment (HP)). Then the audio terminal (TA) decodes the metadata 41 it displays on a screen (DpIy) (the audio terminal (TA) or any other display screen adapted to this display).
- This metadata includes, for example, the name of the title being broadcast.
- the audio terminal then extracts the interactivity query that is included in the metadata. This request is for the display of the message "Buy this title?” and waiting for the user's command. The terminal realizes this poster on the screen (DpIy).
- the intermediation platform (PIM) receives (44) the request identified with the token 001 (of the purchase type of the broadcast title), sent by the terminal (TA) of serial number "123".
- the request analysis module analyzes the request and transmits to the action activation module the fact that the user wishes to purchase the title: the order of the title is transferred to the third party commercial platform PC which verifies the rights of the user.
- terminal user U 123 (for example that the credit balance is greater than 0) and the title is added to the catalog of the customer available in streaming and download (sending an e-mail).
- the request recording module records (46) the received request as well as its result and then performs processing (47), such as statistical processing, that it makes available (48) of the PR platform of the radio R for example, for the latter to become aware of a purchase of title.
