MPEG
ISO/ITU-T (Telecommunications Standardisation Sector of ITU), ITU, is involved in defining a standard for data compression of moving pictures. Its work follows on from that of JPEG (dealt with single pictures) to add inter field compression, the extra compression potentially available through similarities between successive frames of moving pictures.
MPEG-1
Uses a data rate of 1.2 Mbps (Mega Bits per Second), the speed of CD-ROM transfer.
MPEG-2
Uses a data rate (also called a bit rate) of from 2 to 10 Mbps. MPEG-2 is the format most favoured for video-on-demand and DVD.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
