Abstract: Aspects of the present invention may be found in a more efficient system and method of implementing Huffman decoding when audio is encoded or decoded using MPEG1 Layer 3 (MP3) or MPEG Advanced Audio Coding (AAC). Various aspects of the invention employ a unified architecture in the implementation of a Huffman decoder. Use of the unified architecture reduces the memory required to implement both MPEG1 Layer 3 (MP3) and MPEG Advanced Audio Coding (AAC) algorithms.

Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. The present invention is operable to perform error concealment of MPEG data within various components within playback, recording, reading and writing data systems. The present invention is operable within existing systems whose components may not be capable of accommodating errors within MPEG data. Whereas prior art systems typically cannot deal with any corruption without either losing the data or suffering some operational failure, the present invention is able to conceal these errors and to continue decoding and presentation of the MPEG data. In certain embodiments, this involves maximizing the available data that contain no errors to conceal those portions of the data that do include errors. The present invention is operable to accommodate various layers while performing error concealment, including the MPEG transport stream layer, the video layer, and the audio layer.

Abstract: Presented herein is a unified decoder architecture. A system comprises a video decoder, instruction memory, and a host processor. The video decoder decodes the video data encoded with the particular standard. The instruction memory stores a first set of instructions and a second set of instructions. The first set of instructions are for decoding encoded video data according to a first encoding standard. The second set of instruction are for decoding encoded video data according to a second encoding standard. The host processor provides an indication to the video decoder indicating the particular encoding standard. The video decoder executes the first set of instructions if the indication indicates that the particular encoding standard is the first encoding standard and executes the second set of instructions if the indication indicates that the particular encoding standard is the second encoding standard.
