(EN) METHOD AND INTERFACE FOR COMMUNICATION BETWEEN A SERVER AND AT LEAST ONE RECEIVER TERMINAL
(FR) PROCEDE ET INTERFACE DE COMMUNICATION ENTRE UN SERVEUR ET AU MOINS UN TERMINAL-RECEPTEUR
Abrégé
(EN) The invention relates to a method for communication between a server and at least one receiver terminal, provided with an access control system, for receiving a number of transport streams and to simultaneously use at least two of the transport streams amongst those received. According to the invention the method comprises the following steps: a) multiplexing the received transport streams to form at least two parallel transport streams, b) interlacing all the parallel transport streams obtained in the previous step to provide the access control module with a single transport stream and c) identification of each of said parallel streams contained within the single transport stream on each change of phase of a clock signal previously generated.
(FR) L'invention concerne un procédé de communication entre un serveur et au moins un terminal-récepteur muni d'un système de contrôle d'accès apte à recevoir une pluralité de flux de transport et à exploiter simultanément au moins deux flux de transport parmi les flux reçus. Le procédé selon l'invention comporte les étapes suivantes: a) multiplexer les flux de transport reçus pour former au moins deux flux de transport parallèles, b) entrelacer l'ensemble des flux de transport parallèles obtenus à l'étape précédente pour délivrer au module de contrôle d'accès un flux de transport unique, c) identifier chacun desdits flux parallèles contenus dans le flux de transport unique à chaque changement de phase d'un signal d'horloge préalablement généré.
