摘要：
A method for transcoding from an H.264 format to a VC-1 format. The method generally comprises the steps of (A) decoding an input video stream in the H.264 format to generate a picture having a plurality of macroblock pairs that used an H.264 macroblock adaptive field/frame coding; (B) determining a mode indicator for each of the macroblock pairs; and (C) coding the macroblock pairs into an output video stream in the VC-1 format using one of (i) a VC-1 field motion compensation mode coding and (ii) a VC-1 frame motion compensation mode coding as determined from the mode indicator.
