摘要: A method for transcoding from an MPEG-2 format to a VC-1 format is disclosed. The method generally comprises the steps of (A) decoding an input video stream in the MPEG-2 format to generate a picture; (B) determining a mode indicator for the picture; and (C) coding the picture into an output video stream in the VC-1 format using one of (i) a VC-1 field mode coding and (ii) a VC-1 frame mode coding as determined from the mode indicator.

摘要: A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) generating a plurality of primary scores by searching along a plurality of primary angles for an edge in the picture proximate a location interlaced with a field of the picture, (B) generating a plurality of neighbor scores by searching for the edge along a plurality of neighbor angles proximate a particular angle of the primary angles corresponding to a particular score of the primary scores having a best value and (C) identifying a best score from a group of scores consisting of the particular score and the neighbor scores to generate an interpolated sample at the location.

摘要: A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) calculating a potential sample at a location interfaced with a first field of the picture by temporal filtering, (B) evaluating a protection condition in a current region around the location after inclusion of the potential sample and (C) calculating an interpolated sample at the location by vertical spatial filtering the first field in response to the protection condition indicating a significant increase in a vertical activity within the current region due to the potential sample.
