Video image encoding device, video image encoding method

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.

1. A video image encoding device for dividing each picture included in video image data into a plurality of blocks and performing an encoding process on each of the plurality of blocks, the video image encoding device comprising:
a calculation unit configured to calculate a decoding time of each group including the plurality of blocks; an encoding amount control unit configured to control an encoding amount of each of the plurality of blocks based on the decoding time; a source encode unit configured to encode each of the plurality of blocks based on the encoding amount that has been controlled and generate compressed data; and an entropy encode unit configured to perform an arithmetic encoding process on the compressed data in each of the plurality of blocks and output a bit stream, wherein 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.
