  • Methods and apparatus for buffering information prior to decoding
    Patent number: 6701065
    Abstract: A system for processing information, such as audio/video information utilized in a DVD player, can be implemented without the need for a buffer, such as a track buffer, located between the source of audio/video information and the demultiplexer which parses a packet of data. The packet of data can then be parsed into audio, video, subpicture, or navigation, portions and stored for decoding. In one embodiment, a DVD player utilizes a circuit that is synchronized to the speed of the DVD drive rather than to the speed of the decoders for each portion of data.
