The output coded signal of the encoder the MPEG-4 encoder and the way

摘要

As for this invention, the coded contents with the addition hint track/truck of specification regard the MPEG-4 encoder which is remembered with the .mp4 file format. As for these tracks/trucks, packet transmission (packetized transmission) (ATM, MPEG-2 TS and IP,...)The pre- segmentation information which shows the method of fragmenting the coded data which is formed to access unit because it makes the size of the packet coincide which is used is included. According to this invention, information of the fragmentation which forms the coded bitstream in independent entity while encoding, is remembered in the fragmentary structure which becomes independent from the .mp4 file. In addition as for this invention, it receives the available coded signal, and the aforementioned coded signal in the output section of the encoder, the way it regards also the terminal which grasps the said coded signal according to the file structure which has suitable sentence structure.
