VIDEO IMAGE ENCODING DEVICE, VIDEO IMAGE ENCODING METHOD, VIDEO IMAGE DECODING DEVICE, AND VIDEO IMAGE DECODING METHOD

摘要

A method includes determining a group to which each block belongs, the blocks being obtained by dividing each picture included in video image data; adding, to an output stream, information of groups including blocks; calculating a decode time for groups and adding the decode time to the output stream; calculating a display time for the groups and adding the display time to the output stream; controlling an encode amount so that data used for decoding all of the blocks included in a group arrives at a receiving buffer of a decoding device by the display time; encoding based on the controlled encode amount; and implementing control so that first data in a next picture does not arrive at the receiving buffer by the display time, when the data used for decoding all blocks in a group does not arrive at the receiving buffer by the display time.
