MPEG-1
     
         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}.
