Abstract

A synchronous, multi-stream decoder provides synchronous playback of multiple streams of encoded digital data (e.g., MPEG streams) for use with, for example, a digital video streaming tool. The decoder includes a parser and decoder for each stream and a decoder engine for determining a target time for the decoders to complete their respective decoding processes. A next target time is preferably computed during a pause of the parsers after a current target time has been reached. In one embodiment, a next target time is computed by computing an average of the differences of stored playback times of the last N decoded frame sets.
