video compression

Compression of sequences of images. Video compression

algorithms use the fact that there are usually only small

changes from one "frame" to the next so they only need to

encode the starting frame and a sequence of differences

between frames. This is known as "inter-frame coding" or "3D

coding".

MPEG is a committee producing standards in this area and

also the name of their standard algorithm. H.261 is

another standard.
