摘要： Techniques for intensity compensation in video processing are provided. In one configuration, a wireless communication device compliant with the VC1-SMPTE standard (e.g., cellular phone, etc.) comprises a processor that is configured to execute instructions operative to reconstruct reference frames from a received video bitstream. A non-intensity-compensated copy of a reference frame of the bitstream is stored in a memory of the device and used for defining the displayable images and for on-the-fly generation of a stream of intensity-compensated pixels to perform motion compensation calculations for frames of the video bitstream.

摘要： The disclosure describes video decoding techniques that utilize parallel processor technology in order to accelerate the decoding processes of image frames. The techniques include defining batches of video blocks to be decoded in parallel with one another. According to this disclosure, a method may comprise defining a first batch of video blocks of an image frame, decoding the first batch of video blocks in a serial manner, defining a second batch of video blocks and a third batch of video blocks relative to the first batch of video blocks, and decoding the second and third batches of video blocks in parallel with one another.

摘要： A video stream (for example, H.264 video) includes intra-encoded portions. Decoding an intra-encoded portion utilizes the result of decoding one or more other portions (called predecessors) in the frame. Frame reconstruction involves identifying a portion that has no predecessor portions that have not been decoded and then initiating decoding of the identified portion(s). When the decoding of a portion is substantially complete, then the remaining portions to be decoded are examined to identify portions that have no predecessors that have not been decoded. By carrying out this method, multiple portions may be decoded simultaneously. Each can be decoded on a different work entity, thereby increasing the rate of decoding of the overall frame. Because deblock filtering a predecessor destroys information needed in the intra-decoding of other portions, prefiltered predecessor information is stored in a buffer for subsequent use during intra-decoding, thereby facilitating simultaneous decoding of multiple portions.
摘要翻译：视频流（例如，H.264视频）包括帧内编码部分。对帧内编码部分进行解码利用对帧中的一个或多个其它部分（称之为前导）进行解码的结果。帧重建涉及识别不具有未被解码的先前部分的部分，然后开始对所识别的部分进行解码。当部分的解码基本上完成时，对待解码的剩余部分进行检查，以识别不具有未被解码的前导部分。通过执行该方法，可以同时解码多个部分。每个可以在不同的工作实体上进行解码，从而提高整个帧的解码速率。由于去块滤波前导部件会破坏其他部分的内部解码所需要的信息，所以将预过滤的前导信息存储在缓冲器中以便在解码过程中进行后续使用，从而便于同时解码多个部分。
