Abstract

Transcoding Digital Video (DV) for Digital Video Cassette Recorder (DVCR) into MPEG-2 intra coding is performed in the DCT domain to reduce conversion steps. Multiplying matrix by transformed data is used for 4:1:1-to-4:2:0 chroma format conversion and 2-4-8 DCT mode to 8-8 DCT mode conversion for parallel processing. M_quant of MPEG-2 rate control is computed in the DCT domain. For MPEG-2 inter coding, fast motion estimations taking advantage of data in the DCT domain are studied for transcoding. Among them, ME with overlapped search range shows better PSNR performance than ME without overlapping.
