MOVING PICTURE ENCODING DEVICE, MOVING PICTURE ENCODING METHOD AND COMPUTER PROGRAM FOR MOVING PICTURE ENCODING

摘要

A motion video encoding apparatus includes: a group determining unit which determines, for each block into which a picture is divided, a group to which the block belongs; a group decode time information computing unit which computes a decode time for each group; a code amount control unit which controls, for each group, an amount of code resulting from entropy encoding of data of each block contained in the group so that data needed for decoding all of the blocks contained in the group arrives at a stream receive buffer provided in a motion video decoding apparatus by a decode time of the group when the data is transmitted to the motion video decoding apparatus at a prescribed transmission rate; a compression unit which compresses the data of each block based on the amount of code of the block; an entropy encoding unit which entropy-encodes the compressed data of each block; and a decode information appending unit which appends, to data to be output, correction information for the decode time of each group which corresponds to a maximum value of a delay for each group due to the entropy encoding and group information indicative of the group to which each block belongs.
