The standard on which such products as Video CD and MP3 audio are based.
The video standard that typically delivers 30/25 (NTSC/PAL) frames per second. With many variations, this format provides low-resolution images but places low demand on the transmission medium.
MPEG1 is the first of a family of motion video and audio compression standards. It provides DCT lossy compression with rather high quality. It is intended for broadcast quality applications, with resolutions based upon the CCIR (now ITU-R) 601 standard for video coding. It uses three coding protocols: Intraframe coding or I-Pictures (no prediction), P-Pictures, incorporating motion prediction from the previous video image and, B-Pictures (bi-directional prediction) which include motion prediction one frame ahead as well as from the previous frame. MPEG2 has largely supplanted MPEG1.
MPEG1 format is often used in digital cameras and camcorders to capture small, easily transferable motion video clips. It is also the compression format used to create Video CDs. In addition, The well-known MP3 audio format is part of the MPEG1 codec. View DVD to MPEG1 Ripper.
Compression scheme for full motion video. Compression algorithm introduced by MPEG in 1991, the common goal of MPEG is to compress 7.7 Meg down to about 150 Kbytes. MPEG1 is designed to provide a resolution of 352 by 240 pixels at 30 frames per second.
