Abstract
The present invention discloses how a transcoder may be used to reduce the bit rate of an MPEG-2 stream by transmitting only the visible area of the movie specified by pan-scan directives. Because the pan-scan conversion is performed prior to transmission, not immediately before display, the non-viewed portion of video does not need to be transmitted.
