Standards Conversion for International HDTV Content Exchange

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.
