Patent

CA 2181460

Information of a specific application, such as, CD-ROM or CD-DA is organized according to a specific information structure and also contains application data related thereto. There is disclosed a method of transferring information organized according to one or more information structures with an information signal (1) subdivided into blocks (2). The header (12) of each block contains an application code (4) and application data (7), while the structure of the application data depends on the application code. According to a layered hierarchical structure (41, 42) the blocks are organized in groups having a group application code (5) and the groups are organized in a volume having a volume application code (6). The invention makes it possible to know the information structure at any moment. Furthermore, an information carrier is described on which such an information signal is recorded. Also an arrangement for receiving and an arrangement for transmitting such information signals are described.

Des informations d'une application spécifique, tel que le CD-ROM ou CD-DA, sont organisées selon une structure d'informations spécifique et contiennent également des données d'application s'y rapportant. L'invention concerne un procédé de transfert d'informations organisées selon une ou plusieurs structures d'informations avec un signal d'informations (1) subdivisé en blocs (2). L'en-tête (12) de chaque bloc contient un code d'application (4) ainsi que des données d'application (7), tandis que la structure des données d'application dépend du code d'application. Selon une structure hiérarchique (41, 42) en couches, les blocs sont organisés en groupes présentant un code d'application (5) de groupes, et les groupes sont organisés dans un volume présentant un code d'application (6) de volume. L'invention permet de connaître la structure des informations à tout moment. L'invention concerne également un support d'informations sur lequel ledit signal d'informations est enregistré. De plus, l'invention concerne un agencement de réception et un agencement d'émission desdits signaux d'informations.
