ABSTRACT:
A process for synchronizing an MPEG decoder, characterized by the process of calculating an actual instant of presentation Tpres of the video of an image, this instant relating to a local clock LSTC, further calculating an offset STOC between Tpres, being the calculated instant of presentation and the PTS label corresponding to the instant of presentation desired by the coder for the video of this image, so as to define a virtual clock VSTC=STCO+LSTC, the presentation of the video corresponding to this image being made at the PTS dates relating to the virtual clock VSTC, wherein this process relates to satellite decoders, MPEG decoders, as well, as digital TV receivers, utilizing a hard disk for recording coded data.
