Abstract:
1. A method for transcoding from an H.264 format to a VC-1 format, comprising the steps of: (A) decoding an input video stream in said 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 said macroblock pairs; (C) coding said macroblock pairs into an output video stream in said 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 said mode indicator; and (D) finishing decoding a macroblock row, in which an H.264 slice does not end at a right end of said macroblock row, to said right end of said macroblock row to form a VC-1 macroblock slice.
