摘要： A compressed dynamic image encoding device is provided, in which a motion vector is generated by searching a reference image for an image area most similar to an image area of a video input signal; a motion-compensated reference image is generated from the motion vector and the reference image; a prediction residual is generated, by subtracting the motion-compensated reference image from the video input signal; the reference image is generated, by adding the motion-compensated reference image and the result of processing performed to the prediction residual; and an encoded video output signal is generated by the processing performed to the prediction residual. The reference image comprises on-screen reference images, located inside a video display screen, and an off-screen reference image located outside the video display screen, and the off-screen reference image is generated based on the positional relationship of plural similar reference images of the on-screen reference images.

摘要： A video processing apparatus includes a reconstruct circuit, a storage device, and an intra prediction circuit. The reconstruct circuit generates reconstructed pixels of a first block of a picture. The storage device at least stores a portion of the reconstructed pixels of the first block, wherein a capacity of the storage device is smaller than a reconstructed data size of the picture. The intra prediction circuit performs intra prediction of a second block of the picture based at least partly on pixel data obtained from the storage device.

摘要： This disclosure describes techniques for coding a video block based on an unclipped version of a motion vector predictor candidate. The techniques include determining a motion vector predictor candidate list including motion vector predictor candidates from neighboring video blocks without clipping the motion vector predictor candidates. More specifically, if one of the motion vector predictor candidates points to a prediction block located outside of a reference picture boundary relative to the current video block, the techniques allow an unclipped version of the motion vector predictor candidate to be included in the candidate list. The current video block is then coded based on a determined unclipped motion vector predictor candidate of the candidate list. Elimination of the motion vector predictor candidate clipping process reduces complexity at both the video encoder and the video decoder.
