Abstract: The key technical process in international exchange of broadcast content is standards conversion. This continues to be an important process as the world moves rapidly into HDTV broadcasting. This paper reviews the general subject of standards conversion. It then discusses the particular requirements of HDTV standards conversion, arising from new production techniques, workflows, and display devices. Particular emphasis is given to the problem of high-quality upconversion and deinterlacing of standard-definition sources. Techniques of motion estimation and picture building are then presented, with special regard to the ways in which phase correlation is applied to HDTV sources. The performance of HDTV standards conversion within a complete broadcast chain is discussed, considering downstream compression performance, for which some new results are presented. Finally, the application of the techniques to other motion-compensated image processing tasks is briefly discussed.

bio
Mike Knee graduated with a degree in Mathematics from Cambridge University in 1980. He then began his career in the broadcast industry at the BBC Research Department, working on scrambling and encryption for pay-TV services. He went on to work on digital television compression, participating in the development of the future ETSI and MPEG-2 standards. From 1991, he worked on motion compensated upconversion for Thomson Consumer Electronics in Strasbourg, France. — Knee joined Snell and Wilcox in 1994 to build up and lead the company's MPEG research activities, leading to MPEG-2 video analysis hardware, picture-quality estimation techniques, high-quality MPEG-2 encoding using the company's Ph.C motion estimation technology, and the highly-acclaimed, SMPTE-standardized MOLE technology, which enables high-quality transcoding and flexible, seamless, and lossless switching and editing of MPEG-2 bitstreams. — More recently, Knee has been working on algorithm developments for motion-compensated deinterlacing, standards conversion, and other temporal processing of image sequences, as well as automatic scene analysis based on image segmentation for application in mobile video. He is leader of the company's Algorithms team. — Knee has contributed to many international conferences and peer-review journals. He is responsible for over 30 patents or patent applications in the fields of compression and video image processing. He is a Chartered Mathematician, a Chartered Engineer, and a member of the IET.
