As the video signals of macroblocks are coded, they are stored in a buffer. When the total code length of the stored macroblocks exceeds a predetermined value, all but the most recently coded macroblock are output from the buffer as a video packet, and the most recently coded macroblock is coded again. To minimize this occurrence, when each coded macroblock is stored, the code length of the next macroblock is predicted and added to the total length, and if the resulting sum exceeds the predetermined value, all of the coded macroblocks stored in the buffer are output as a video packet.
