摘要： A video multiplexing apparatus includes: a control unit which determines first decode/display time information and second decode/display time information for each picture in video data and for each encoding unit of first media data; a video packet generating unit which appends the first and second decode/display time information for the picture to encoded data of the video data; and a media packet generating unit which appends the first and second decode/display time information for the encoding unit to encoded data of the first media data. The first decode/display time information is used when the decoding unit of the video data is a picture, and the second decode/display time information is used when the decoding unit is a sub-picture. The picture display time based on the second decode/display time information is earlier than the picture display time based on the first decode/display time information.

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.

摘要： A video encoding apparatus appends decoding delay correction information 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 in the video data than a first picture that may potentially be spliced to a trailing end of other encoded video data have been discarded, the first picture and subsequent pictures in the encoded video data can be continuously decoded and displayed by a video decoding apparatus. The video decoding apparatus corrects the decoding delay and display delay of the first picture and its subsequent pictures by using the decoding delay correction information and display delay correction information.
