More MPEG Triadic Technologies

It has always been a point of pride for MPEG to have been able to create the MPEG-1 Audio-Video-Systems package overcoming the informal, but nonetheless effective barriers that used to separate video coding people, audio coding people and those more “engineering minded” that MPEG calls “systems people”. This “package approach”…

MPEG-B Part 1 “Binary MPEG format for XML” (BiM) was originally developed a the technology to compress MPEG-7 Descriptors and Description Schemes and placed in MPEG-7 Part 1. BiM was then made a generic technology and moved to MPEG-B part 1. It provides a standard set of generic technologies to…

MPEG-C Part 1 “Accuracy specification for implementation of integer-output IDCT” specifies the IDCT accuracy that is equivalent to or extends the IEEE 1180 standard. This standard referenced by quite a few image and video compression standards had been withdrawn and MPEG needed to restore the reference. Part 2 “Fixed-point 8×8…

MPEG-D Part 1 “MPEG Surround” provides an efficient bridge between stereo and multichannel presentations in low-bitrate applications. The MPEG Surround technology supports very efficient parametric coding of multi-channel audio signals, so as to permit transmission of such signals over channels that typically support only transmission of stereo (or even mono)…

While MPEG was busily developing more and more video compression standards, China decided that it could well afford to have its own national digital audio-video-system technology and in June 2002 established the Audio and Video Coding Standard Workgroup of China (AVS). The group achieved its goal and in December 2003…
