What is the MPEG committee ?
In fact, MPEG is a nickname. The official title is: ISO/IEC JTC1 SC29 WG11. ISO: International Organization for Standardization IEC: International Electrotechnical Commission JTC1: Joint Technical Committee 1 SC29: Sub-committee 29 WG11: Working Group 11 (moving pictures with… uh, audio) What ever happened to MPEG-3 ? MPEG-3 was to have targeted HDTV applications with sampling dimensions up to 1920 x 1080 x 30 Hz and coded bitrates between 20 and 40 Mbit/sec. It was later discovered that with some (syntax compatible) fine tuning, MPEG-2 and MPEG-1 syntax worked very well for HDTV rate video. The key is to maintain an optimal balance between sample rate and coded bit rate. Also, the standardization window for HDTV was rapidly closing. Europe and the United States were on the brink of committing to analog-digital subnyquist hybrid algorithms (D-MAC, MUSE, et al). By 1992, European all-digital projects such as HD-DIVINE and VADIS demonstrated better picture quality with respect to bandw
