摘要:
Methods and apparatus are provided for supporting a variable-length transport packet in an Audio/Video (AV) communication system. Data to be transmitted is determined. It is determined whether a transport packet is the variable-length transport packet. A header having information indicating whether the transport packet is the variable-length transport packet is generated. When the transport packet is the variable-length transport packet, an optional header having length information of the transport packet is generated, and the data and the transport packet having the header and the optional header, are transmitted. When the transport packet is not the variable-length transport packet, the determined data and the transport packet having the header are transmitted.

Methods and apparatus are provided for supporting a variable-length transport packet in a audio and video communication system. Data to be transmitted through a transport packet is determined. A header of the transport packet is generated. The header includes a start sync signal. When a length of the transport packet exceeds a reference size, at least one intermediate sync signal is inserted into the transport packet according to a pre-defined interval. The transport packet is transmitted.

摘要:
Cette invention concerne un support d'enregistrement optique, un dispositif et un procédé d'entregistrement/reprodction de données sur ledit support et à partir de ce dernier, un procédé d'enregistrement de données sur ordinateur stockant un programme d'exécution du procédé d'enregistrement de données sur/à partir dudit support d'enregistrement d'informations. Une zone d'entrée, une zone de données et une zone de sortie sont agencées sur le support d'enregistrement. La zone d'entrée et la zone de sortie comprennent une structure de définition de disque (DDS)/zone de gestion d'enregistrement (RMD) pour l'enregistrement d'informations sur une gestion défectueuse et sur la gestion de l'enregistrement. Dans la zone DDS/RMD sont écrites la structure (DDS) utilisée pour la gestion dédfectueuse et une zone RMD. La zone de données comprend une partie libre (SA)/liste de défauts (DL) pour l'enregistrement de données de rechange remplaçant des données défectueuses sur le support d'enregistrement et des information sur les défectuosités du support d'enregistrement. Un bloc DDS/RMD comprenant des informations d'attribution de zone de données et des informations d'initialisation utilisées pour gérer le support d'enregistrement est enregistré dans une première partie enregistrable de la zone DDS/RMD. Lees information's d'attribution de zone de données comprennent des informations d'emplacement d'une zone DDS/RMD disposée dans la zone de données et des informations d'emplacement de la zone SA/DL. IL est ainis possible de gérer efficacement la capacité de stockage d'un disque grace à une gestion efficace des defectuosités sur le disque.
摘要:
A write-once disc, an apparatus for recording information thereon, and a method of reducing access time thereto the write-once disc including at least one record layer. The write-once disc also includes at least one update area in which updated predetermined information is recorded; and an access information area in which location information regarding the updated predetermined information, is recorded for a predetermined period. Accordingly, it is possible to reduce an access time for reading information updated in the write-once disc on which predetermined information is updated and recorded on a new position.
