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.
