En outre, tel que connu, les fonctionnalités disponibles du boîtier sont affichées sur le téléviseur sous la forme d'une Interface Homme Machine (IHM) qui permet de proposer un certain nombre de fonctionnalités à un utilisateur : mosaïque de chaînes, services payants tels que la vidéo à la demande. Il s'agit en fait de tous les services proposés par le fournisseur de contenu. La figure 3 illustre un téléviseur 100 comprenant une zone 101 destinée à afficher le contenu numérique et une interface homme machine 102. In addition, as known, the available features of the housing are displayed on the TV in the form of a Human Machine Interface (HMI) which allows to propose a number of features to a user: mosaic of channels, pay services such as video on demand. This is actually all the services offered by the content provider. FIG. 3 illustrates a television 100 comprising a zone 101 intended to display the digital content and a man-machine interface 102.
Afin de contrôler le boîtier numérique 400 au moyen de la télécommande 100 du téléviseur 200, le système comprend une carte de contrôle 300 connectée d'une part au boîtier 400 et d'autre part au téléviseur 200.  In order to control the digital box 400 by means of the remote control 100 of the television 200, the system comprises a control card 300 connected on the one hand to the box 400 and on the other hand to the television 200.

Cette prise de contrôle n'est pas automatique.  This takeover is not automatic.
On décrit ci-dessous un procédé de contrôle du boîtier numérique au moyen de la télécommande.  Described below is a method of controlling the digital box by means of the remote control.
Procédé  Process
La figure 4 illustre schématiquement un procédé de contrôle du boîtier numérique du système de diffusion présenté ci-dessus.  Figure 4 schematically illustrates a control method of the digital box of the broadcast system presented above.
De manière générale le contrôle s'effectue en deux temps. Dans un premier temps, on a une prise de contrôle du boîtier numérique au moyen de la télécommande et dans un second temps le contrôle en tant que tel du boîtier numérique au moyen de la télécommande. In general, the control is carried out in two stages. At first, there is a control of the digital box by means of the remote control and in a second time the control as such of the digital box by means of the remote control.
On considère que le téléviseur diffuse 51 un contenu numérique et qu'un canal de communication entre la carte et le boîtier numérique est ouvert 58.  It is considered that the television broadcast 51 digital content and a communication channel between the card and the digital box is open 58.
Prise de contrôle  Take over
Pour prendre le contrôle du boîtier, la carte va détecter 52 un signal particulier émis par la télécommande. La carte comprend à cet effet des moyens 302 pour détecter ce signal particulier.  To take control of the box, the card will detect a particular signal from the remote control. The card comprises for this purpose means 302 for detecting this particular signal.
Un tel signal particulier est par exemple le signal correspondant à l'appui sur la touche « Ok » de la télécommande.  Such a particular signal is for example the signal corresponding to pressing the "Ok" key on the remote control.
De manière générale, ce signal particulier correspond à l'appui sur une touche de la télécommande qui n'a aucun effet particulier sur le téléviseur lorsque celui-ci diffuse un contenu audiovisuel issu du réseau hertzien.  In general, this particular signal corresponds to pressing a key on the remote control that has no particular effect on the television when it broadcasts audiovisual content from the wireless network.
Lorsque la logique de la carte va détecter 52 le signal particulier, elle va l'interpréter 53 comme étant le signal particulier qui indique que l'on veut commander le boîtier numérique et va envoyer 54 au téléviseur l'interface homme machine 301 de contrôle du boîtier numérique. Cette interface homme machine 301 est stockée dans la carte 300.  When the logic of the card will detect the particular signal, it will interpret it as the particular signal indicating that it is desired to control the digital box and will send to the TV the man-machine interface 301 of the control. digital housing. This human machine interface 301 is stored in the card 300.
L'interface homme machine 301 est envoyée sous la forme de données au format conforme à l'interface DVB-CI ou DVB-CI+ (en anglais, « Common Interface » ou « Common Interface + »). Pour plus d'informations, on pourra se référer au document : ETSI-EN50221 : « Common Interface Spécification for Conditional Access and other Digital Video Broadcasting Décoder Applications » ainsi qu'au document « Cl Plus Spécification. Content Security Extensions to the Common Interface ».. Les données transportées au format Cl ou CI+ sont du type CEA-2014 (voir le document Mark R. Walker : « CEA 2014 Overview, CEA R7WG9 », janvier 2007) ou MHEG5 (en anglais, « Multimedia and Hypermedia Experts Group 5 » (MHEG)). Ce type de données est un type bien connu de données pour ce qui concerne les services numériques interactifs. The human machine interface 301 is sent in the form of data in the format compliant with the DVB-CI or DVB-CI + interface (in English, "Common Interface" or "Common Interface +"). For more information, refer to ETSI-EN50221: "Common Interface Specification for Conditional Access and other Digital Video Broadcasting Decode Applications" and the document "Cl Plus Specification". The data transported in CI or CI + format are of the CEA-2014 type (see Mark R. Walker document: "CEA 2014 Overview, CEA R7WG9", January 2007) or MHEG5 (in English). , "Multimedia and Hypermedia Experts Group 5" (MHEG)). This type of data is a well-known type of data for interactive digital services.
Dans une variante, la carte 300 peut être intégrée au boîtier numérique 400.  In a variant, the card 300 can be integrated into the digital box 400.
L'interface homme machine 301 est interprétée par le téléviseur 200 et convertie en une interface homme machine « affichable » 101 .  The human machine interface 301 is interpreted by the television 200 and converted into a "displayable" human machine interface 101.
En particulier, il s'agit de données qui peuvent être stockées dans le décodeur numérique qui sont interprétées, ces données étant conformes au formant CEA-2014 ou MHEG5.  In particular, it is data that can be stored in the digital decoder that are interpreted, these data being in accordance with the CEA-2014 or MHEG5 training.
L'interface homme machine affichable va s'afficher en incrustation sur le contenu numérique diffusé et par conséquence proposer plusieurs actions possibles : un changement de chaînes, des services, un contrôle du volume, etc. En fait, l'interface homme machine 101 va permettre d'accéder à toutes les fonctions offertes par le boîtier numérique.  The displayable man-machine interface will appear in overlay on the digital content broadcast and consequently propose several possible actions: a change of channels, services, a volume control, etc. In fact, the human machine interface 101 will allow access to all the functions offered by the digital box.
En outre, il est possible de prévoir des mises à jour du boîtier et de l'interface homme machine. Pour ce faire des données mises à jour sont émises par l'infrastructure du fournisseur d'accès 30.  In addition, it is possible to provide updates of the housing and the man-machine interface. To do this updated data is issued by the infrastructure of the access provider 30.
Contrôle du boîtier numérique  Digital box control
Au moyen de la télécommande, un utilisateur va choisir une des actions proposées par l'interface homme machine 101 .  By means of the remote control, a user will choose one of the actions proposed by the man-machine interface 101.
Un tel choix s'effectue en appuyant sur une touche de la télécommande.  Such a choice is made by pressing a key on the remote control.
Le signal reçu par le téléviseur est envoyé sur la carte 300 qui va associer ce signal reçu à un contrôle du boîtier numérique 400.  The signal received by the television is sent to the card 300 which will associate this received signal with a control of the digital box 400.
Pour ce faire, la carte 300 comprend des moyens 302 pour associer chaque signal reçu par la télécommande à un contrôle du boîtier numérique 400.  To do this, the card 300 comprises means 302 for associating each signal received by the remote control with a control of the digital box 400.
La carte 300 va transmettre 56 l'action voulue au boîtier numérique The card 300 will transmit 56 the desired action to the digital box
400. 400.
Ainsi, la carte 300 permet le contrôle du boîtier numérique 400 au moyen de la télécommande d'origine du téléviseur 200. Dans tous les cas, une fois l'action effectuée, la télécommande peut servir à commander 57 la télévision de manière conventionnelle sans passer par le boîtier numérique 400. Thus, the card 300 allows the control of the digital box 400 by means of the original remote control of the television 200. In any case, once the action is performed, the remote control can be used to control the television in a conventional manner without going through the digital box 400.
De manière avantageuse, la carte 300 est connectée au réseau 20 sur lequel est diffusé le contenu numérique issu de l'infrastructure du fournisseur d'accès 30.  Advantageously, the card 300 is connected to the network 20 on which is broadcast the digital content from the infrastructure of the access provider 30.
Ainsi, les commandes provenant de la télécommande peuvent être interprétées par l'infrastructure 30 qui peut, en réponse, envoyer directement au boîtier l'action à effectuer. Dans ce cas, c'est l'infrastructure 30 qui prend le contrôle du boîtier numérique.  Thus, the commands from the remote control can be interpreted by the infrastructure 30 which can, in response, send directly to the box the action to be performed. In this case, the infrastructure 30 takes control of the digital box.
De cette façon on n'est plus obligé d'avoir le boîtier numérique à proximité du téléviseur comme c'est souvent le cas.  In this way we are no longer obliged to have the digital box near the TV as is often the case.
