<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.
