摘要： A flexible software-based decoding system with decoupled decoding timing and output timing. In one embodiment, a computer software implemented method of decoding a data stream comprising encoded video data is provided. In this embodiment, the software method comprises the step of maintaining a number of already decoded and ready-for-output frames in a frame buffer. The method also comprises the step of decoding a first encoded frame of the data stream to generate an additional decoded frame. The method further comprises the step of outputting a first of the decoded frames before decoding of the first encoded frame is completed if the decoding step requires more time than a predefined frame output time to complete. Moreover, in this embodiment, the method comprises the step of adding the first additional decoded frame to the frame buffer. In this embodiment, real-time output is maintained irrespective of whether completion of the decoding step requires more time than the predefined frame output time for particular frames. In one embodiment, the method further comprises the step of decoding a second encoded frame of the data stream substantially immediately upon completion of the decoding step to generate a second additional decoded frame, provided that the completion of the decoding step requires more time than the predefined frame output time, and also the step of adding the second additional decoded frame to the frame buffer.

摘要： In case of decoding by a software process, in the process 1, video data of a decoded frame corresponding to a management ID stored at the head of an output FIFO 4 at its time point is read out and outputted. In the process 2, audio data is decoded. In the process 3, the video data is decoded. The decoded video data is stored in a video frame buffer and its management ID is stored in the output FIFO 4 in the outputting order. When the process 3 cannot be finished, the process 3 is interrupted during the process and the image of the frame stored at the head of the output FIFO 4 is outputted. After that, when the process 2 is finished, the decoding process of the process 3 which was temporarily interrupted is restarted. In case of performing the encoding by the software process, an encoding amount of the video data as a processing target of the encoding is predicted. Subsequently, whether an empty capacity enough to store the data of the predicted encoding amount exists in a code buffer or not is discriminated. If it is determined that there is the empty capacity, the encoding is started and the video data in which the encoding was finished is deleted from the video frame buffer. The encoding is temporarily interrupted when a reading process or the like of the video data is performed.

摘要： An apparatus and method of decoding coded video bitstreams is disclosed. The apparatus comprises a first processor and a second processor configured to operate in parallel. The main processor receives the coded video bitstream, parses it, and calls the second processor to decode the coded video bitstream to retrieve macroblock data. If an error occurs during decoding, the second processor signals the first processor, which can instruct the second processor to perform an error recovery routine. The first processor the performs dequantization and inverse DCT to recover digital pixel data from the macroblocks so that an image formed from the digital pixel data can be later displayed on a monitor.
