    摘要： A method for coding a block of video data in simplified block prediction mode of a constant bitrate video coding scheme for transmission over display links is disclosed. In one aspect, the method includes determining a candidate block to be used to predict a current block in a current slice, the candidate block being within a range of pixel positions that each correspond to a reconstructed pixel in the current slice. The range of pixel positions may comprise (i) a first region including one or more first pixel positions in a first line of pixels that overlaps the current block, and (ii) a second region including one or more second pixel positions in a second line of pixels that does not overlap the current block. The method may further comprise determining and signaling a prediction vector indicative of a pixel position of the candidate block.

    摘要： A method and apparatus for video coding with spatial prediction mode for multi-mode video coding is disclosed. In one aspect, the method includes coding a slice of video data, the slice including a plurality of pixels organized into a first line and a plurality of non-first lines. The coding of the slice further includes coding a current pixel of the first line in a spatial prediction mode using a previous pixel of the first line as a predictor and coding another pixel of a non-first line in a coding mode other than the spatial prediction mode.
