Definitions
- the field of the invention relates to methods for managing the broadcasting of multimedia content and in particular video content through a data network comprising at least one satellite broadcast. More particularly, the invention relates to methods for broadcasting multimedia content, filtering and storage at the user, including a content recommendation method.
- the most common means is the dissemination of video content broadcast over the Internet network for example through a CDN network.
- a CDN network comprises different servers for relaying the content to be broadcast to users.
- This broadcast is generally performed according to a unicast protocol, that is to say a point-to-point network connection. In this way, each user receives "his" content independently of other users.
- a problem with unicast broadcasting of multimedia content is that the network can be quickly saturated by the number of requests and the volume of data exchanged.
- a problem directly related is that the quality of the service is not always guaranteed for a user. For example, the download times of multimedia content may increase, which increases the time to wait for the provision of multimedia content.
- the quality of content especially because of compression, is sometimes degraded to ensure, however, a minimum service.
- the availability of content may be limited depending on the number of requests and the time of download. In the country or regions where the terrestrial infrastructure is not very developed, the diffusion of contents according to a unicast protocol is even impossible.
- a second means is to broadcast satellite video content to a plurality of users.
- the multicast protocol makes it possible to broadcast content from one point to a plurality of points of a network.
- the problem is that the satellite channel is generally used to broadcast the same content to a plurality of users at the same time. This operation does not make it possible to respond adequately to a "video on demand" type service.
- a single user accesses, after receiving a request, particular content at a particular time. His application is dissociated from that of thousands of other users. If the content is available and the bandwidth, via the satellite transponders, is not saturated, then the content can be distributed to the user. On the other hand, this system finds limitations when many requests are made at the same time and the contents requested are different. In addition, the cost of the satellite band used can be high and therefore not compatible with a commercial service.
- a satellite link can be used to broadcast to a set of users of the video content.
- the latter can be recorded on a disk for later viewing, this solution is also called more commonly "Push VOD”.
- the invention solves the aforementioned drawbacks by improving the user experience of a satellite Push VOD service, to the point of getting as close as possible to the experience of a real VOD service on a network not overloaded.
- An object of the invention relates to a method of filtering a set of contents broadcast by a satellite link.

Thus each user is likely to consult the media catalog and choose a media to view.
- the object of the invention is to maximize the probability that the media is already stored by the user equipment through the method of the invention.
- the filtering method previously comprises a determination of at least one user filter performed by a remote computing unit.
- An advantage of the invention is to determine user filters by a remote unit calculating similarities between different user filters so as to predict a media list of a catalog for each user.
- the user filter is determined according to a user profile previously transmitted from the user equipment to the remote computing unit.
- An advantage is to take into account data from a user profile and correlate them with data from a set of user profiles to calculate similarity indicators and optimize the list of media that will be stored by the user equipment.
- the user profile comprises at least one of the following parameters:
- ⁇ User data including:
- a user information collection function is performed to define the user profile in the user equipment, said information comprising at least one of these data or a combination of these data:
- the user profile is periodically calculated by means of calculations of the user equipment and is periodically transmitted to the remote computing unit;
- ⁇ the user filter is periodically calculated by the remote computing unit from the broadcast user profile and media catalog.
- a transmission means establishes a connection by satellite and comprises means for determining the unicast or multicast transmission protocol according to the data to be transmitted, the first reception being established by a unicast protocol and the second reception is established by means of a multicast protocol.
- the first and second transmissions are periodically performed with a respective period.
- the remote computing unit comprises a memory for storing the user profiles received from a plurality of user equipment and the user filters generated from said user profiles and the catalog.
- the remote computing unit makes comparisons between at least one given user profile and a set of user profiles and generates correspondence data, a filter given user being generated based on the match data and the given user profile.
- the remote computing unit generates a priority index for each content of the first list as a function of the correspondence data.
- Another subject of the invention concerns a device for filtering a set of multimedia contents, comprising:
- At least one component decoder decodes the IP packets of a signal received by said filtering device
- ⁇ filtering filter component each multimedia content received according to a user updated filter and stored in a memory of the filtering device, said content being filtered:
- ⁇ is stored in a memory of said filtering device
- ⁇ is passed to an output interface to perform a backup of the filtered content in an external drive.
- the filtering component performs:
- ⁇ comparing a value date of a recorded content in a memory or a hard disk with a time threshold value so as to keep or automatically remove such content.
- the filtering device comprises a second input connector for receiving modulated signals, said second input connector being connected to a demodulator making part of the filtering device, the demodulator processing the demodulated data to filter the IP frames and deliver them to the IP switch.
- the IP switch switches IP frames received from the demodulator to the Ethernet port.
- the filtering device comprises a first input connector for receiving demodulated signals comprising a received data stream, said data being transmitted to the decoder decoder component.
- the first input connector makes it possible to transmit signals comprising IP frames to an external signal modulator.
- the decoder component comprises a power supply for supplying the IP switch, the filtering component and the converter.
- the converter converts the IP multicast frames received into IP unicast frames, said IP unicast frames comprising a new addressing and being routed to an Ethernet port of the filtering device.

- the emitter E- ⁇ being connected to the terrestrial network.
- a plurality of servers comprise all or part of the CAT catalog, the CAT catalog files being able to be distributed on different data servers.
- a central monitoring server includes a management component to know the access routes to other servers and to access the content to be broadcast by satellite.
- Another server includes a user management component CG U. This component makes it possible to calculate all the user filters that will be transmitted subsequently to each user equipment EQ U.
- Each user management component CG U is able to query the server SERV including the CAT catalog of media to update in particular the media lists L u which are indicated in each user filter F u .
- the transmitting antenna Ei comprises the components necessary for sending frames of data on at least one transmission frequency to a satellite SAT.
- the transmitting antenna of the transmitter Ei is associated with a modulator MOD which makes it possible to modulate the data to be transmitted on a transmission channel comprising a predefined bandwidth.
- An SE- ⁇ signal is then transmitted to the satellite SAT.
- the satellite SAT includes channels carrying the received signal to a Tx-i broadcast antenna.
- the redirected and broadcast signal is processed, for example, when it is retransmitted at a frequency other than the center frequency of the received signal.
- the signal processed at the satellite is filtered and amplified.
- the data is then broadcast over a region comprising a set of receivers Ri, R 2 , R 3 -
- Each receiver R- ⁇ , R 2 , R 3 is associated with at least one user equipment, denoted EQu.
- the receivers Ri, R 2 , R 3 are capable of receiving a signal transmitted by the antenna Tx1 of the satellite SAT in a diffusion channel.
- a receiver may be associated with more than one user equipment EQ U as shown with the receiver R 3 . This may be the case when a receiver is used for a building or for an infrastructure serving different EQu user equipment.
- Each receiver Ri, R 2 , R 3 receives and demodulates the received signal and transmits the data to the user equipment EQu.
- FIG. 2 represents a filtering device 1 of the invention that is intended to be present in an EQu user equipment.
- the transmitted data is multimedia data meeting a need for video on demand.
- the disseminated data is included in a catalog CAT made available to a user subscribed to a service.
- the method of the invention includes steps for filtering a selection of a catalog based on criteria determined according to a user profile and social data of a community of users.
- the filtering method of the invention can be implemented in particular by a filtering device represented in FIG. 2.
- a first component can be connected via an interface 10 to the filtering device 1 of the invention.
- the first ODU component is a demodulator for demodulating the signal received from the satellite SAT.
- the ODU component transmits the demodulated data to the filtering device 1.
- the ODU component is capable of modulating data transmitted by the filtering device 1 for transmission to the satellite SAT. He then realizes a return way.
- the ODU may include an amplifier for amplifying the signal to be transmitted to the satellite SAT.
- the modulation of the signal received by the ODU component is compatible with the DVB-S transmission standard, DVB-S2, DVB-S2X.
- the ODU component comprises an encoder for encoding the data to be transmitted.
- the return link can therefore be provided from the user equipment EQu to the satellite.
- the data transmitted by this link back can be modulated for example by a modulation type DVB-RCS.
- the modulation may also be, for example, spread spectrum modulation. This modulation makes it possible to reduce the transmission powers and thus avoids the congestion of a high power amplifier in the ODU component. It can then integrate more easily by being more compact.
- the filtering device 1 comprises an Ethernet or coaxial interface.
- the interface When the interface is coaxial, it may for example be of the EoC type to transmit IP frames in a coaxial connector.
- two interfaces may be provided including a coaxial and an Ethernet.
- the filtering device 1 of the invention comprises a decoder component, denoted IDU, decoding the frames of the IP protocol of a signal received by the filtering device 1 from the ODU component.
- the IDU component also makes it possible to encode IP frames so as to transmit them to the ODU external component in case of a link back to the satellite SAT.
- the IDU decoder component comprises a power supply for powering an IP switch, a filtering component and a converter.
- the device of the invention comprises a switch, denoted SW IP.
- SW IP switch
- the packets received by the IP switch are directed to the PC filtering component.
- the filtering component PC then makes a decision on the nature of the frames received to process the data.
- the filtering component PC compares in particular the received IP frame data with a user filter F u .
- the comparison can also be performed after compilation of a set of frames of the same multimedia content received. For example, when a set of frames relates to the same content such as a video, the comparison can be made using a movie identifier or a movie name.
- the content is: either saved in a memory for possible later viewing, or not recorded.
- the PC filtering component saves media filtered by the PC filtering component in a memory M of the filtering device 1 of the invention.
- the backup of the filtered media can be performed on a memory external DD, such as a hard disk or a solid state disk such as a "flash" memory.
- the filtering device 1 of the invention comprises an interface 14 for connecting an external hard disk DD or a key.
- Such an interface may be of USB type or any other interface allowing the transfer of data.
- the filtering component PC thus comprises a user filter F u making it possible to discriminate received media:
- a remote computing entity makes it possible to perform calculations between a user profile P u and social data to generate the user filter F u .
- the user filter F u will then be transmitted and dedicated to a given user equipment EQu.
- the IP SW switch directs these frames to a BPC noted converter.
- the BPC converter converts multicast IP frames into unicast IP frames.
- protocol or multicast sending a protocol or sending a content to a plurality of users.
- a protocol or "unicast” sending a protocol or sending a content to a single user is called; it is therefore an individual shipment.
- a problem is that the satellite broadcast is generally performed by a multicast protocol, that is to say that the same content is broadcast to a plurality of users, while more and more, the processing of data received by satellite requires customization adapted to the use of each.
- This concerns in particular the securing of the data transmitted, the interactivity enabled by a satellite return link allowing for example the exchange of keys or encryption certificates, the sending of votes, the deployment of the Internet protocol or the personalization of the content to be broadcast.
- the BPC converter converts multicast IP frames into unicast IP frames. Once converted, the converted frames can be redirected to the IP SW switch to be directed to the appropriate component, such as the PC filtering component.
- the method of the invention makes it possible to reconstruct the entirety of a video file from received IP frames and the added redundancy in the data frames.
- the added redundancy can be achieved through a given encoding such as, for example, an FEC coding or a "digital fountain" algorithm.
- the content is then saved to the hard disk or memory.
- the filtering device of the invention comprises, in one embodiment, a second input connector 1 1 for receiving modulated signals from a receiver REC external to the filtering device 1 of the invention.
- a demodulation component denoted DEMOD, is capable of demodulating the modulated signals received and coming from the second input connector 11.
- the input connector 11 may be in one embodiment a coaxial connector.
- the connector 1 1 is advantageously intended to be connected to a receiver REC comprising an antenna for receiving a signal from a satellite SAT.
- the receiver REC comprises a component for converting the signal into an intermediate frequency band and mixing the different signals in the same coaxial interface.
- the DEMOD demodulator allows, in addition to signal demodulation, to process the demodulated data to filter IP frames and non-encapsulated video frames in IP frames.
- the processing then includes routing the decoded IP frames to the IP SW switch and routing unencapsulated video frames in IP frames to an STB video component.
- the STB video component processes the demodulated data and is capable of decoding the video frames to generate an image or to compile frames to form a media file.
- the STB video component is able to transmit compatible video frames of a display for their display.
- the IP frames decoded by the DEMOD component can be routed to an Ethernet port 13 via the SW IP switch, to the BPC converter component or to the filtering component.
- the SW IP switch directs the frames to an external SW WIFI switch via the Ethernet port 13
- the frames sent allow viewing of the multimedia content on external viewing equipment.
- Each addressed device decodes the IP frames in order to reconstruct the relevant multimedia stream.
- Various viewing equipment such as a television, a tablet, a computer or a smartphone can be addressed by the SW WIFI external switch.
- the latter may be for example a switch or a wireless router.
- the IP frames sent to the SW switch have a multicast protocol, as before, they are routed to the BPC so that the frame headers are changed to unicast. Then, the frames are re-transmitted to the SW switch to be directed to external equipment accessible from the SW WIFI wireless external switch via the interface 13 or to the PC filtering component.
- the filtering device 1 therefore comprises, according to one embodiment, a demodulator DEMOD and a decoder component IDU.
- This embodiment allows the filtering device 1 to be compatible with different data transmission protocols broadcast by satellite SAT and to receive a demodulated or modulated signal in a frequency band transposed around an intermediate frequency.
- the filtering device 1 of the invention may comprise only the DEMOD demodulator or only the IDU decoder component or both components.
- the invention also relates to a method for filtering multimedia content received by the satellite SAT by a user equipment EQU.
- the PC filtering component comprises calculation means such as a computer for performing the calculation and comparison steps and making the decisions relating to the processing of the received frames. - Reception of the Fu user filter
- the method includes receiving a user filter F u by an EQu user equipment.
- the user filter F u can be transmitted by a satellite link or a terrestrial link depending on the available connection of the PC filtering device.
- the IP switch When the user filter F u is received by a terrestrial link, the IP switch is, for example, connected to a local area network connected to the internet. The user filter F u is addressed to a given user via the internet network.
- the unicast protocol can be advantageously used to address data to a single user.
- the user filter F u includes a user identification
- the user filter F u comprises a list of multimedia contents, denoted first list L u .
- the list L u corresponds to a subset of the CAT multimedia catalog of the remote server SERV or of the different servers hosting the CAT catalog.
- the list L u can specify a priority for the content, so that the user filter F u can choose the content to be recorded, taking into account the space available on the storage device (memory M or disk DD), and possibly delete recorded content for longer than a predefined threshold or content with low priority.
- User Profile P u
- the user filter F u is set by the management component through a user profile P u and a set of social data.
- the user profile P u is established within a user equipment EQ U.
- a user profile P u can include different types of information. For example, it may include information about the user himself and such habits as for example:
- the user profile P u may comprise, in one embodiment, a set of data that a user has informed about his tastes and the type of media he likes to view:
- ⁇ Data about the category of a film such as an actor, director, producer, broadcaster that a user likes.
- the user profile P u may include data collected during these previous views, for example:
- the type of media among the following: ⁇ music, video, games ⁇ viewed and the proportion of each type of media viewed.
- a note given by a user to a media make it possible to develop a user profile P u that can evolve over time according to the history of the media viewed.
- a transmission of a user profile P u can be programmed and sent at regular times and times predefined in time to the user management component.
- a user management component CG U is shown in FIG.
- the user management component CG U sends to a set of users and thus to a set of user equipments EQ U the set of user filters ⁇ F u ⁇ ie [! N] , each user filter F u having been calculated for each individual of a given population.
- the user filters F u are in particular processed and routed to the user equipment EQ U and thus to the filtering device 1 of the invention to be saved until a new user filter F u is received to replace it.
- the catalog CAT and the user management component CGu are on the same server SERV.
- two servers respectively perform the function of calculating the user filters and hosting the CAT catalog.
- the management component can be configured on the remote server SERV comprising the CAT catalog. According to another embodiment, the management component is configured on another computer or another server accessing the CAT catalog media list hosted on the remote server SERV.
- Each list L L i can be regularly updated if it changes over time and sent to each filtering device 1.
- the list L u is dynamic in that it is regularly updated according to parameters evolving over time. The criteria for updating a list L u depend on the evolution of the user profile and social data.
- Social data includes viewing data or profile data of other users having matches with a given user.
- part of the same set of media will be proposed in a list of a given user who has not viewed the media of that part but having also watched some of the media of this set.
- the transmitter E1 via the transmitting antenna associated with the remote server SERV transmits a film catalog regularly to a set of users of an area covered by the satellite transmitting antenna T x SAT.
- the catalog CAT is sent in pieces or subassemblies according to a programming in a predefined duration.
- the CAT catalog includes hundreds, if not thousands, of media. Among these media, there are for example films, documentaries, games, music files or other multimedia content. These media are transmitted by satellite broadcasting at times of the day or night on terrestrial regions covered by the antenna T x files concerned.
- Each user equipment EQ U defining or comprising the filtering device 1 of the invention comprises means for receiving the files of the multimedia catalog CAT.
- the method of the invention therefore comprises a step of receiving the CAT catalog files or a part of the catalog, for example, using a "push" or "datacast” type protocol that can reconstruct a file from the fragments. , possibly by applying error correction algorithms.
- satellite reception may take place:
- a receiver configured to receive signals from a satellite SAT broadcast and to demodulate said received signals.
- the method of the invention comprises a step of filtering the media received according to the user filter F u recorded in the user equipment EQ U.
- the user filter F u has been received by the user equipment EQ U and has been saved in a previous step.
- a medium is present in the user filter Fu, then it is stored in a memory M or DD after filtering. If the space available in the memory M or DD is not sufficient, the filter F u uses the priority of the media to possibly erase low priority content to make room for higher priority content.
- a received medium is not present in the user filter F u , or when the space is completely occupied by higher priority media, then it is not stored in a memory M or DD after filtering.
- the internal memory M or the external memory DD of the filtering device comprises a list of media corresponding to the list L u of the user profile F u .
- An advantage of backing up part of the CAT catalog is to allow immediate access to a user to a part of the CAT catalog which is directly stored on an internal or external memory of the user equipment EQ U.
- EQ U When viewing a media stored on a memory M or DD, no disturbance can affect the viewing.
- the method of the invention is therefore of interest for maintaining a quality of viewing for a user having a user equipment implementing the method of the invention.
- An advantage of using an algorithm based on the user profile P u and on all the viewing data of the other users is that it makes it possible to optimize the probability of viewing a content already stored by a user. and thus potentially deletes the on-demand download step of a given media.
- the on-demand download of a given media by a given user at a given time requires much more network resources and bandwidth than when the media is broadcast once for a set of users with a possibility to save this content if the probability of viewing is high.
- Another advantage of this invention is to limit storage requirements at the user. Indeed, thanks to the advanced algorithms that are used to establish the lists L u from profiles P u of all the users, the disk or memory used can be of rather limited size, even if the CAT catalog is very wide. This reduces the cost of the equipment for the user of this video-on-demand service.
