    摘要: 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.

    摘要: Presented herein are system(s), method(s), and apparatus for AC coefficient prediction. In one embodiment, there is presented a method for predicting AC coefficients for a macroblock. The method comprises determining whether a particular block is predicted from a top neighboring block or a left neighboring block; retrieving from a buffer, data from the top neighboring block or left neighboring block from which the particular block is predicted; and writing data from the particular block to the buffer.

    摘要: Presented herein is a dual context audio parser. A header of the audio frame is provided for parsing, the header forming a portion of a particular packet. A first portion of the audio frame is provided for parsing, the first portion of the audio frames being stored in a memory. A second portion of the audio frame is provided for parsing, the second portion of the audio frame forming another portion of the particular packet, after the first portion is parsed.
