Methods and systems for processing streams of media data. The system may allow for the demultiplexing (110) of a multiple multi-program transport stream ("MPTS") into a single program transport stream ("SPTS"). The system also provides a data structure for storing a program that facilities the rapid positioning at a desired time within the program during playback. In addition, the system when recording a program time processes time discontinuities so that positioning based on time during playback can occur rapidly. The system also allows a live television broadcast to be paused indefinitely in way that will not use up all system storage and will allow the most recent broadcast to be available for playback.

Cette invention concerne des procédés et des systèmes de traitement de lux de données de média. Avec ce système, il est possible de démultiplexer (110) un flux de transport multi-programme multiple ("MPTS") en un flux de transport pour programme unique ("SPTS"). Le système fait également intervenir une structure de données pour le stockage d'un programme qui facilite le positionnement rapide et au moment voulu à l'intérieur du programme pendant la lecture. Par ailleurs, pendant l'enregistrement d'un programme, le système traite les discontinuités de temps de sorte que le positionnement temporel pendant la lecture peut se faire rapidement. Il est possible de marquer indéfiniment une pause dans un programme de télévision en direct sans utiliser tout le système de stockage et d'interrompre indéfiniment un programme en direct pour passer la diffusion disponible la plus récente.
