This overview paper considers the applications driving today's progress in video communication and then reviews the principles behind advanced video compression technology, such as standardized in ITU-T Rec. H.263 or ISO MPEG. In addition, we look at the problem of robustness against packet loss, that has to be solved to transmit video over wireless channels or the Internet. Addressing promising directions for the future development of video compression, we discuss and illustrate the performance of multiframe prediction methods and advanced motion models.
