It works by attempting to predict the motion from frame to frame in the temporal direction, then using discrete cosine transforms to organize the redundancy in spatial directions. The DCTs are performed in small blocks, and the collection of data is Huffman coded using fixed tables. Recently, the ISO chose Apple's Quicktime software as the basis for the forthcoming fourth revision of this standard. FTP, name this ISO standard, perhaps most popular for the ease of bootlegging that its "layer 3" audio compression provides.
