Abstract:
A video receiver system comprises a video elementary stream decoder that decodes an elementary stream and one or more trick mode processing modules that modify the elementary stream to enable a trick mode effect. The trick mode processing module(s) produce a trick mode elementary stream for input to the video elementary stream decoder module. For example, the one or more trick mode processing modules can replace plural non-key frames of the elementary stream with one or more P-type skipped frames for a fast forward effect, where the trick mode elementary stream comprises one or more entry point key frames and the one or more P-type skipped frames. The video receiver system can selectively route the elementary stream to either the video elementary stream decoder module or the one or more trick mode processing modules.
