The so-called edit code method refers to a method of converting a video format file into another video format file through a specific compression technique. The most important coding and decoding standards for video streaming today are ITU H. 261, H. 263, M-JPEG of Motion Still Images Experts Group and MPEG Series Standards of ISO Motion Picture Experts Group. Also widely used on the Internet are Real-Networks' RealVideo, Microsoft's WMT, and Apple's QuickTime. .
MPEG is an abbreviation of the Moving Picture Exports Group. Founded in 1988, it is an expert group that develops compression standards for digital video/audio, and currently has more than 300 members, including IBM, SUN, BBC, NEC, INTEL, AT&T and other world-renowned companies. The original authorization obtained by the MPEG organization was to formulate various standards for "moving image" encoding, which was subsequently expanded to "and its accompanying audio" and its combined encoding. Later, for the needs of different applications, the restrictions on “for digital storage media†were lifted, becoming the current organization that has established the “active image and audio coding†standard. The various standards established by the MPEG organization have different goals and applications, and MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21 standards have been proposed.
