MPEG-1

(compression, standard, algorithm, file format)The firstMPEG format for compressed video, optimised for CD-ROM.MPEG-1 was designed for the transmission rates of about 1.5Mbps achievable with Video-CD and CD-i.

It uses discrete cosine transform (DCT) and Huffman codingto remove spatially redundant data within a frame andblock-based motion compensated prediction (MCP) to removedata which is temporally redundant between frames. Audio iscompressed using subband encoding. These algorithms allowbetter than VHS quality video and almost CD quality audio tobe compressed onto and streamed off a single speed (1x)CD-ROM drive.

MPEG encoding can introduce blockiness, colour bleed andshimmering effects on video and lack of detail andquantisation effects on audio.

The official name of MPEG-1 is International StandardIS-11172.
