Video Services (moving images) There is a need to strictly follow strong delay requirements to provide a good illusion of motion; essential to provide realtime performance. h.261 video compression pdf Performance of the H. 263 Video Compression Standard BERND GIROD, ECKEHARD STEINBACH AND NIKOLAUS FARBER Telecommunications Institute, University of ErlangenNuremberg, Cauerstrasse 7, Erlangen, Germany Abstract. The draft international standard ITUT H. 263 is closely related to the well known and widely used ITUT Recommendation H. 261.

The algorithm, which is used by the MPEG standards, will be elucidated upon in order to explain video compression. Only visual compression will be discussed (no audio compression).
