Abstract

In this paper, principles for conversions in pre- and post- processing for HDTV are analyzed, the theoretically ideal processing of the sampling format conversion between YUV4:4:4 and YUV4:2:2, YUV4:2:2 and YUV4:2:0, the size conversion between digital TV standards, and frame rate conversion are presented. The proposed principle is applied in post-processor of HDTV prototype, finally the precision of these post- processing algorithms are reported.
