mpeg-3









































mpeg-3 is the designation for a group of audio and video coding standards agreed upon by the moving picture experts group (mpeg) designed to handle hdtv signals at 1080p in the range of 20 to 40 megabits per second. mpeg-3 was launched as an effort to address the need of an hdtv standard while work on mpeg-2 was underway, but it was soon discovered that mpeg-2, at high data rates, would accommodate hdtv. thus, in 1992 hdtv was included as a separate profile in the mpeg-2 standard and mpeg-3 was rolled into mpeg-2.

all algorithms for mpeg-1 audio layer i, ii and iii were approved in 1991 as the committee draft of iso-11172 and finalized in 1992 as part of mpeg-1, the first standard suite by mpeg, which resulted in the international standard iso/iec 11172-3 (a.k.a. "mpeg-1 audio" or "mpeg-1 part 3"), published in 1993. further work on mpeg audio was finalized in 1994 as part of the second suite of mpeg standards, mpeg-2, more formally known as international standard iso/iec 13818-3 (a.k.a. "mpeg-2 part 3" or backward compatible "mpeg-2 audio" or "mpeg-2 audio bc"), originally published in 1995. mpeg-2 part 3 (iso/iec 13818-3) defined additional bit rates and sample rates for mpeg-1 audio layer i, ii and iii. the new sampling rates are exactly half that of those originally defined for mpeg-1 audio. mpeg-2 part 3 also enhanced mpeg-1's audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel.
