Abstract

The module has a conditional access module or DVB-common interface module with inputs (TS-in, Wifi) and outputs (TS-out, HDMI). The access module decrypts a channel during utilization using a smart card. The output (HDMI) permits a hardwired link towards an HDMI bus corresponding to an integrated digital television receiver. The output (HDMI) is connected on the television and on a DVD-HD cutter/recorder, to record an HD flow while viewing an SD flow coming from a tuner of the television.

Description

2890518 12890518 1

La présente invention a pour objet un module de récepteur numérique 5 pour IDTV supportant le MPEG4 HD Il concerne le domaine industriel et commercial de la fabrication et de la diffusion d'équipements destinés aux récepteurs de télévision raccordés aux réseaux satellite et câble.  The present invention relates to a digital receiver module 5 for IDTV supporting MPEG4 HD It relates to the industrial and commercial field of manufacturing and broadcasting equipment for television receivers connected to the satellite and cable networks.

Il a pour objet la réception de données numériques audiovisuelles transmises par un réseau de télécommunications, et plus particulièrement des diffusions émises selon le protocole "MPEG" utilisées généralement pour la transmission par satellites.  Its object is the reception of audiovisual digital data transmitted by a telecommunications network, and more particularly broadcasts transmitted according to the "MPEG" protocol generally used for satellite transmission.

Les récepteurs numériques (aussi appelés STB ou Set-Top Box) sont présents dans de nombreux foyers et permettent de recevoir les chaînes numériques de télévision et de radio, le moyen de transmission pouvant être aussi bien le satellite, le câble ou les ondes hertziennes.  Digital receivers (also known as STB or Set-Top Box) are present in many homes and can receive digital TV and radio channels, the transmission means can be as well satellite, cable or airwaves.

Ces récepteurs incorporent en général au moins un connecteur dit "à interface commune" ou "DVB-CI" (Common Interface) ou "cablecard", qui permettent d'insérer un module "DVB-CI" ou "CAM" (Conditional Access Module) ayant en général pour but de décrypter la chaîne en cours d'utilisation, éventuellement avec l'aide d'une carte à puce.  These receivers generally incorporate at least one connector called "common interface" or "DVB-CI" (Common Interface) or "cablecard", which allow to insert a module "DVB-CI" or "CAM" (Conditional Access Module ) generally intended to decrypt the string in use, possibly with the help of a smart card.

ÉTAT DE L'ART / PRINCIPE Le déposant a développé un premier chip NP4 supportant le décodage du MPEG4 SD. Grâce à un mécanisme breveté, le transcodage, de manière à 30 réinjecter le flux en MPEG2 SD sur le bus TS out des interfaces normalisées DVB et Cablecards.  STATE OF THE ART / PRINCIPLE The applicant has developed a first NP4 chip supporting the decoding of MPEG4 SD. Thanks to a patented mechanism, the transcoding, so as to reinject the stream in MPEG2 SD on the TS out bus of the standardized interfaces DVB and Cablecards.

Il est très probable que dans un futur plus ou moins proche, certains opérateurs proposeront des services audiovisuels au format MPEG4 HD, notamment les opérateurs satellites et câbles.  It is very likely that in a more or less near future, some operators will offer audiovisual services in MPEG4 HD format, including satellite operators and cables.

En considérant qu'un processus de transcodage MPEG4 HD vers MPEG2 HD n'est pas réalisable actuellement en raison de la non-possibilité de réinjecter du MPEG2 HD sur le TS-out de l'interface DVB Cl, l'architecture utilisée dans ce premier composant doit être modifiée pour le support de la HD.  Considering that an MPEG4 HD to MPEG2 HD transcoding process is not currently feasible due to the inability to re-inject MPEG2 HD on the TS-out of the DVB C1 interface, the architecture used in this first component needs to be changed to support HD.

Aussi, l'utilisation d'une liaison câblée vers le bus HDMI qui se trouve 10 généralement présent dans les IDTV (Integrated Digital TeleVision) semble être la seule solution pour injecter le flux HD dans un IDTV.  Also, the use of a cable link to the HDMI bus which is generally present in IDTVs (Integrated Digital TeleVision) seems to be the only solution for injecting the HD stream into an IDTV.

L'avantage de cette solution est de conserver la solution module afin de récupérer le TS-in pour traitement de la source d'alimentation: on reste dans une solution "plug and play", compatible avec la première solution NP4, la sortie HDMI n'étant à connecter que pour recevoir les flux HD.  The advantage of this solution is to keep the solution module to recover the TS-in for processing the power source: it remains in a solution "plug and play", compatible with the first NP4 solution, the HDMI output n being connected only to receive HD streams.

Sur le dessin annexé, donné à titre d'exemple non limitatif d'une forme de réalisation conforme à la présente demande, la figure 1 représente un schéma des connexions du module "CAM".  In the accompanying drawing, given by way of non-limiting example of an embodiment according to the present application, Figure 1 shows a circuit diagram of the module "CAM".

Le dispositif est constitué d'un module "CAM" MPEG4 comportant plusieurs entrées et plusieurs sorties et en particuliers une sortie pour liaison câblée vers le bus HDMI.  The device consists of a module "CAM" MPEG4 having several inputs and several outputs and in particular an output for wired connection to the HDMI bus.

Il est important de conserver le transcodage pour les flux SD car, dans ce cas, le module comporte deux entrées (TS-in, Wifi) et deux sorties (TSout et HDMI) ; on peut alors router les flux de manière flexible et programmable simplement par l'utilisateur via l'interface MMI du module (grâce notamment à la spécification type C).  It is important to preserve transcoding for SD streams because, in this case, the module has two inputs (TS-in, Wifi) and two outputs (TSout and HDMI); it is then possible to route the flows in a flexible and programmable manner simply by the user via the MMI interface of the module (thanks in particular to the type C specification).

La sortie HDMI peut ainsi être branchée non seulement sur le téléviseur mais aussi sur un graveur/enregistreur DVD-HD, ce qui permet d'enregistrer un flux HD tout en regardant un flux SD provenant du tuner du récepteur de télévision ou d'Internet via le Wifi.  The HDMI output can be connected not only to the TV but also to a DVD-HD recorder / recorder, allowing you to record an HD stream while watching an SD stream from the TV tuner tuner or the Internet via Wifi.

Il est également possible de regarder un flux HD et d'enregistrer simultanément un flux SD sur un ordinateur via le Wifi.  It is also possible to watch an HD stream and simultaneously record an SD stream on a computer via Wifi.

Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects that had not been obtained so far by similar devices.
