Title (EN) SYSTEM AND METHOD FOR STORING AND FORWARDING AUDIO AND/OR VISUAL INFORMATION ON DEMAND
(FR) SYSTEME ET PROCEDE DESTINES A STOCKER ET A TRANSMETTRE DES INFORMATIONS AUDIO ET/OU VISUELLES SUR DEMANDE
Abstract:
(EN) A system and method for storing and forwarding audio/video signals on demand is shown including an encoder (105) for receiving, digitizing, and compressing audio/video signals into a data stream, and a first processing system for further compressing and storing the data stream received from the encoder, and for later transmitting the data stream via a transmitting system to a location remote from the first processing system. The first processing system preferably also includes a microprocessor. The second processing system includes a microprocessor for receiving, processing, and storing the data stream from the remote first processing system, and later transmitting a copy of the data stream, upon receipt of a request for replay of the audio/video signal after retrieving and decompressing the copy of the data stream. Such system and method also includes a decoder for further decompressing and transforming the data stream into an analog signal for transmission to at least one television set for replay.
(FR) Système et procédé destinés à stocker et à transmettre des signaux audio/vidéo sur demande, qui comporte un codeur servant (105) à recevoir, à numériser et à comprimer les signaux audio/vidéo dans un train de données, et un premier système de traitement servant à comprimer encore et à stocker le train de données reçu du codeur et à transmettre ensuite le train de données par l'intermédiaire d'un système d'émission en un lieu éloigné du premier système de traitement. Le premier système de traitement comporte de préférence un microprocesseur. Le second système de traitement comporte un microprocesseur pour recevoir, traiter et stocker le train de données provenant du premier système de traitement, et pour transmettre ensuite une copie du train de données, sur réception d'une demande de repassage du signal audio/vidéo après récupération et décompression de la copie du train de données. Ledit système comporte également un décodeur pour décompriner et transformer le train de données en signal analogique destiné à être transmis à au moins un poste de télévision en vue du repassage.
