Title (EN) DIGITAL VIDEO TRANSPORT ERROR HANDLING IN CELL BASED COMMUNICATIONS SYSTEMS
(FR) GESTION DES ERREURS DANS LE TRANSPORT DE SIGNAUX VIDEO NUMERIQUES DANS DES SYSTEMES DE COMMUNICATION FONDES SUR DES CELLULES
Abstract:
(EN) In a communications system packets containing compressed digital signals are transported in multiple cells, typically in an Asynchronous Transfer Mode format. Upon reception of these cells (410), a determination is made as to whether cells have been lost (418), additional cells inserted, or whether there were bit errors in the transmission of the cells (434). If so, null packets are substituted for the erred packets and are sent to the video decompression layer (438, 442).
(FR) Dans un système de télécommunication des paquets contenant des signaux numériques comprimés sont transportés dans plusieurs cellules, plus spécifiquement dans un format de mode de transfert asynchrone. Lorsque ces cellules sont reçues, on détermine si des cellules ont été perdues, si des cellules supplémentaires ont été introduites ou s'il existe des erreurs de bits dans la transmission des cellules. Dans ce cas des paquets d'annulation sont substitués aux paquets erronés puis envoyés à la couche de décompression vidéo.
