It was advised ITU (the International Telecommunication Union) by in 2003 May, one of standard of compressed coding system of the animated picture data. Portion of animated picture compressed standard MPEG-4 (MPEG-4 Part 10 Advanced Video Coding) as ISO (International Organization for Standardization) with, being advised, it is. Because of this, general like “H.264/MPEG-4 AVC” “H.264/AVC”, when naming both is recorded ? is many.

MPEG-4 Part 10 Advanced Video Coding, for the portable telephone of terrestrial digital broadcast broadcast “[wansegu]” and, SONY portable game machine “PSP”, “HD DVD” of the next generation DVD and “Blu-ray Disc” and portable music player “iPod” of the Apple corporation and with multimedia software “QuickTime” and so on is adopted as standard animated picture type

MPEG-7

Field:
Multimedia > animated picture > MPEG-7

Standard technology of description method in order to search the multimedia contents of animated picture and sound etc effectively. As for formal name you call “description interface of the multimedia contents (Multimedia Content Description Interface)”.

As for the purpose of MPEG-7 it differs from MPEG-1/2/4 which designates compression encoding of the multimedia contents as purpose largely.

When reaching the point where it can procure & can utilize the various multimedia contents in the future, through Internet and CATV etc, those contents must be enjoyed purely, without being able to trouble the hand in management of the mass multimedia contents.
