Compression of sequences of images. Video compression algorithm s 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 standard s in this area and also the name of their standard algorithm . H.261 is another standard.
