Motion estimation and its application to HDTV transmission and Up-Conversion Using DATV

G. A. Thomas

Motion compensation is a key technique in HDTV signal processing, both for bandwidth reduction and display field rate up-conversion. During the last few years, an effective motion estimation algorithm has been developed by the BBC as a part of its contribution to the Eureka 95 HDTV project. In view of the promising results obtained by computer simulation, a hardware realisation of the motion estimator has been built, in order to allow its performance to be assessed on a much wider range of picture material that would ever be possible by computer simulation. This paper outlines the motion estimation algorithm, and describes the real-time hardware. Some of the first results obtained from the hardware are presented.
