Abstract: A method and apparatus for synchronizing a data stream that contains video data in which the video data includes frames. As frames are being processed, a number of frames processed is identified along with a number of frames dropped during processing. A synchronization speed is identified using the number of frames processed and the number of frames dropped. A frame is selectively dropped from the data stream based on the synchronization speed.

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.

Abstract: An improved method and apparatus for processing a data stream containing multiple data packets, which can contain audio or video data. The present invention parses a data stream until it reaches the start of a packet containing audio or video data. This data is bundled by the present invention. For data packets crossing over multiple buffers, multiple bundles are created. One bundle for packets crossing multiple buffers can be made if the data it maps to can be coalesced into a discrete continuous buffer. Information is associated with this bundle containing the first and last buffer indexes such that when the bundle is consumed, the corresponding buffers can be released. Otherwise, a separate bundle will be created for each separate buffer until the end of the packet is reached and when all bundles for an associated buffer are consumed then the buffer can be released.
