ABSTRACT:
A method for converting a program stream to a transport stream is described comprising: reading program stream packets from a digital versatile disk (“DVD”) based on user selections and navigation metadata contained on the DVD; extracting audio and video content packetized within the program stream packets; reading system clock reference (“SCR”) timestamps from the program stream packets, the SCR timestamps indicating relative times at which the audio and video should be rendered; determining a point within consecutively read program stream packets at which the SCR timestamps are non-consecutive; converting the SCR timestamps to program clock reference (“PCR”) timestamps interpretable by a transport stream decoder; and generating a transport stream of transport stream packets containing the audio and video content and using the PCR timestamps to provide for decode timing at the transport stream decoder; and generating a resynchronization signal causing the transport stream decoder to resynchronize with the transport stream when it receives corresponding non-consecutive PCR timestamps associated with the non-consecutive SCR timestamps.
