MPEG-3 was the designation for an abandoned plan to create a group of audio and video coding standards agreed upon by the Moving Picture Experts Group (MPEG) designed to handle HDTV signals at 1080p [1] in the range of 20 to 40 megabits per second. [2]
MPEG logo Some well known older (up to 2005) digital media formats and the MPEG standards they use. The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.

The algorithms for MPEG-1 Audio Layer I, II and III were approved in 1991 [14] [15] and finalized in 1992 [16] 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. [7]
Hiroshi Yasuda (born 1944) is an Emeritus Professor at the University of Tokyo and works as a Consultant for Nippon Telegraph and Telephone. [1]In the sphere of international standardization, together with Leonardo Chiariglione he founded the Moving Picture Experts Group which standardized MPEG-1 Audio Layer 3, better known as MP3.
MPEG-2 Part 3 also defines additional bit rates and sampling rates for MPEG-1 Audio Layers I, II, and III. [12] This extension is known as MPEG-2 LSF (low sampling frequencies), since the new sampling rates are one-half multiples (16, 22.05 and 24 kHz) of the sampling rates defined in MPEG-1 (32, 44.1 and 48 kHz).

MPEG-1 is a standard for lossy compression of video and audio.It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) [2] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.
