Abstract:
An apparatus having a first circuit, a second circuit and a third circuit. The first circuit may be configured to (i) demultiplex a multimedia stream having one or more video and audio streams and (ii) generate one or more video signals and one or more audio data signals in response to demultiplexing the multimedia stream. The multimedia stream may be independent of embedded time stamps. The second circuit may be configured to (i) decode the one or more video data signals and the one or more audio data signals and (ii) generate a video current time signal for each decoded video signal and an audio current time signal for each decoded audio signal. The third circuit may be configured to synchronize the playback of each decoded audio signal and each decoded video signal with the video current time signal and the audio current time signal.
