Abstract: A system, method, and apparatus for playback of multiple video elementary streams is presented herein. A host processor modifies the video elementary streams to allow a transport demultiplexer to distinguish among the plurality of the video elementary streams.

Abstract: Presented herein are a system, method, and apparatus for audio and video synchronization. In one embodiment, there is presented a method for displaying audio data and video data. The method comprises examining a plurality of portions of the audio data, where each of said plurality of portions of audio data is associated with a time stamp; examining a plurality of portions of the video data, where each of said plurality of portions of the video data is associated with a time stamp; decoding one of the portions of the video data; and decoding one of the portions of the audio data while decoding the one of the portions of the video data. The difference between the time stamp associated with the one of the portions of the video data and the time stamp associated with the one of the portions of the audio data is within a certain margin of error from a predetermined offset.

Abstract: Presented herein is a compressed structure for writing slice group start codes into a start code table, for use with a video decoding system. One or more start codes are written to a start code table. The presentation time information is written to the start code table.

Abstract: Described here are systems and methods for providing data starting from start codes aligned with byte boundaries in multiple byte words. A start code is written starting at a byte in a middle portion of a data word in a memory. An address associated with the byte is written in a table. Data is fetched from the memory starting from the byte.

Abstract: Presented herein are system(s) and method(s) for handling audio jitters. In one embodiment; there is presented a method for decoding an audio signal. The method comprises receiving a portion of the audio signal, the portions of the audio signal associated with a time stamp; comparing the time stamp associated with the portion of the audio signals to a reference time; generating another portion of the audio signal, if the time stamp is later than the time reference by over a certain margin or error; and dewindowing the another portion with a previously played portion of the audio signal, thereby resulting in a an another dewindowed portion.

Abstract: A system and method for detecting PES headers is presented herein. PES headers are detected by a combination of hardware and firmware. Hardware logic is used to detect the PES start codes while multithreaded firmware us used to process the packet.

Abstract: Presented herein are system(s) and method(s) for handling audio jitters. In one embodiment; there is presented a method for decoding an audio signal. The method comprises receiving a portion of the audio signal, the portions of the audio signal associated with a time stamp; comparing the time stamp associated with the portion of the audio signals to a reference time; generating another portion of the audio signal, if the time stamp is later than the time reference by over a certain margin or error; and dewindowing the another portion with a previously played portion of the audio signal, thereby resulting in a an another dewindowed portion.

Abstract: Described herein are system(s), method(s), and apparatus for embedding personal video recorder functions in transport packets. In one embodiment, there is described a method for commanding a video processor. The method comprises generating a transport packet; placing an indicator in the transport packet, said indicator indicating that the transport packet contains commands for the video processor; and placing commands in the transport packet. The transport packet comprises no more than 130 bytes.
