Abstract: A method includes reading selected portions of video content from a digital versatile disk (“DVD”), said selected portions of video content separated by periods of time to provide a fast forward or rewind mode; generating a transport stream of transport stream packets containing said selected portions of video content; and in response to detecting said fast forward or rewind mode, causing a transport stream decoder to decode said transport stream packets without synchronization.

Abstract: A method is described for rendering subpicture images comprising: reading a subpicture image from a digital versatile disk (“DVD”); identifying regions within the subpicture image for which ? is below a specified threshold value; and rendering on a video screen only those regions of the subpicture image for which ? is above the specified threshold value.

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 tr
