Both High-Definition Television (HDTV) and Standard-Definition Television (SDTV) use the MPEG-2 video coding standard, but they have different spatial resolutions. In order to support interlaced video coding, MPEG-2 incorporates various macroblock coding modes. Thus the HDTV to SDTV transcoding needs to handle non-integer factor spatial resolution down-scaling and various MPEG-2 macroblock coding modes. Taking into consideration the details of MPEG-2 macroblock coding modes, we propose motion re-estimation algorithms specially tailored for HDTV to SDTV transcoding.
