Computing | 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.

(From Wikipedia, the free Encyclopedia)
Notions: video is basically a three-dimensional array of color pixels. Two dimensions serve as spacial (horizontal and vertical) directions of the (moving) pictures and one dimension represents the time domain. A frame is a set of all pixels that (approximately) correspond to a single point in time. Basically, a frame is the same as a (still) picture. However, in interlaced video, the set of horizontal lines with even numbers and the set with odd numbers are grouped together to fields. The term picture can refer to a frame or a field.
Method: Video data contains spatial and temporal redundancy. Video compression removes this redundancy lossy. Usually this is achieved by:
