Abstract
Converting video information from a first compression format to a second compression format, including receiving data for a sequence of pictures in the first compression format, the received data including a video stream corresponding to a video program and including for a picture that is inter coded motion vectors and quantized transform coefficients of residuals of motion compensated inter-coded blocks. The converting also includes extracting auxiliary information including one or more auxiliary data elements from the received data; and transcoding from the first compression format to the second compression format, including carrying out motion estimation for blocks of image data in the second compression format. Carrying out motion estimation for blocks of image data in the second format includes using the auxiliary information to ascertain whether to use a first motion estimation method or a second motion estimation method different from the first motion estimation method.
