< compression , standard , algorithm , file format > The first MPEG format for compressed video , optimised for CD-ROM . MPEG-1 was designed for the transmission rates of about 1.5 Mbps achievable with Video-CD and CD-i .
It uses discrete cosine transform (DCT) and Huffman coding to remove spatially redundant data within a frame and block-based motion compensated prediction (MCP) to remove data which is temporally redundant between frames. Audio is compressed using subband encoding . These algorithms allow better than VHS quality video and almost CD quality audio to be compressed onto and streamed off a single speed (1x) CD-ROM drive.
MPEG encoding can introduce blockiness, colour bleed and shimmering effects on video and lack of detail and quantisation effects on audio.
The official name of MPEG-1 is International Standard IS-11172 .
