摘要： A video encoding apparatus appends decoding delay and display delay correction information to encoded video data in order to ensure that even when one or more pictures that are later in encoding order than a starting encoded picture in a video data stream to be spliced to a trailing end of another encoded video data stream have been discarded from among pictures contained in the video data stream, the starting encoded picture and its subsequent pictures can be continuously decoded and displayed by a video decoding apparatus. The correction information is calculated based on a decoding interval between each discarded picture and a picture that immediately precedes the discarded picture. The video decoding apparatus corrects the decoding delay and display delay of the starting encoded picture and its subsequent pictures by using the calculated correction information.

摘要： A video decoder decoding an encoded stream includes a parallel entropy decoding part to entropy decode the stream of blocks in block lines in parallel, a parallel QP prediction part to compute prediction values of the blocks in the block lines in parallel, and a parallel decoding processing part to generate decoded pixels of the blocks in the block lines in parallel, the decoded pixel being obtained utilizing data decoded by the parallel entropy decoding part and the prediction value. When performing computing processing in parallel per unit of N block lines, the processing is performed on a processing block in a (K−1)th block line preceding a processing block in a Kth block line by at least one block in a horizontal position to compute the prediction value of the processing block by referring to a block already processed corresponding to the processing block.

摘要： A video image encoding device includes a calculation unit for calculating a decoding time of each group including plural blocks; a source encode unit for encoding each of the plural blocks based on the encoding amount of each block controlled based on the decoding time and generating compressed data; and an entropy encode unit for performing an arithmetic encoding process on the compressed data in each block and outputting a bit stream. The entropy encode unit outputs undetermined bits retained by the arithmetic encoding process when all bits corresponding to the compressed data in each group are not output at a time point when the arithmetic encoding process on the compressed data in a predetermined number of blocks in a next group is finished, and the calculation unit shifts the decoding time of each group by a processing time of the predetermined number of blocks.
