摘要： In aspects of the present disclosure, a software encoder augments a hardware encoder by implementing portions of a video encoding task that are not supported by the hardware encoder while the hardware encoder implements other portions of the encoding task. The use of a software encoder to augment a hardware encoder in this manner can extend the useful life of a hardware encoder, allow the system to adapt to changes in video coding standards, and in some cases improve performance of encoding implemented by hardware or software alone. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： A method and apparatus for decoding an input MPEG video stream are provided that includes a core processor with a very long instruction word (VLIW) processor and a co-processor that includes a variable length decoder (VLD) for decoding the MPEG video stream. The input MPEG video stream is organized into macroblocks, wherein each macroblock includes a header for a macroblock that is not decoded, and encoded data for a macroblock whose header is previously decoded by VLD. Thereafter, VLD decodes the encoded video data of a first macroblock whose header has been decoded, and decodes the header of a second (current) macroblock. VLIW then performs motion compensation on a current macroblock based upon reference data of a previously decoded macroblock. VLIW also adds a fake slice start code and fake macroblock data at the end of each picture into the input MPEG video data stream; and utilizes the fake slice start code and fake macroblock data to skip to a next slice. The fake macroblock data indicates an error to the VLD stopping the decoding process until the core processor clears the interrupt and reinitiates decoding of a selected macroblock.
摘要翻译：提供了一种用于解码输入MPEG视频流的方法和装置，其包括具有非常长的指令字（VLIW）处理器的核心处理器和包括可变长度解码器（VLD）的协处理器，用于解码MPEG视频流。输入的MPEG视频流被组织成宏块，其中每个宏块包括一个未被解码的宏块的头部，以及由VLD预先解码头部的宏块的编码数据。此后，VLD解码其首标已解码的第一宏块的编码视频数据，并对第二（当前）宏块的标题进行解码。然后，VLIW基于先前解码的宏块的参考数据对当前宏块执行运动补偿。 VLIW还在每个图像的末尾添加假片起始码和假宏块数据到输入的MPEG视频数据流中; 并利用假片起始码和假宏块数据跳到下一片。伪宏块数据指示VLD停止解码过程的错误，直到核心处理器清除中断并重新开始对所选宏块的解码。

摘要： A method and system for decoding and reconstructing an incoming MPEG video data stream for producing decoded MPEG video data is provided. The method and system utilizes a first memory storage device with at least two memory buffers associated with a co-processor, and a second memory device with a plurality of memory buffers associated with a core-processor. Also provided is a first data transfer unit coupled to the first memory storage device and the second memory device. The first data transfer unit in response to a first signal from the core processor selects one of the first memory storage device buffer (B0) as a source and a buffer in the second memory storage device as a destination buffer (MB_B0′). The data transfer unit is adapted to read content from B0 and write the content of B0 to MB_B0′. Simultaneously, data transfer unit also selects the other buffer of the first memory storage device (B1) as a second source buffer and a second destination buffer (MB-B1′) from the plurality of buffers in the second memory storage device. Again the data transfer unit is adapted to read the content of B1 and write the content of B1 to MB_B1′, wherein the transfer from B1 to MB_B1′ comprises a wait indicating that a transfer from B0 to MB-B0′ is complete.
