Abstract

A method and apparatus for processing a data stream including audio and video data in which high data rates and throughput is required. Thresholds are employed to control the processing of video and audio data in a data stream. Video data is decoded in response to a comparison of audio and video data to threshold values. Additionally, another threshold value is employed to control buffers storing audio data in response to an underflow of audio data.
