Digital audio and/or video programs that have been compressed on the basis of groups of pictures (GOPs) are recorded on a medium that allows immediate jumping between groups through co-storage of Transport Stream packets and pointer information. In particular, coexistently with the storing, successive pointers are derived in realtime from a primary Transport Stream that collectively point to data packets in a reconstructed Transport Stream, which contains entry points. These pointers are stored at predetermined locations on the medium.
L'invention concerne des documents audio et vidéo comprimées sur la base de groupes d'images (GOP). Ces documents audio et vidéo comprimées sont enregistrés dans un support qui permet de passer instantanément d'un groupe à un autre par le biais d'un stockage simultané de paquets d'un courant de transport et de données de pointeur. En particulier, en même temps que s'effectue le stockage, des pointeurs successifs sont extraits en temps réel d'un courant de transport primaire qui pointe sur des paquets de données pris collectivement dans un courant de transport reconstitué contenant des points d'entrée. Ces pointeurs sont stockés à des emplacements préétablis dans le support.
