Abstract
Techniques for intensity compensation in video processing are provided. In one configuration, a wireless communication device compliant with the VC1-SMPTE standard (e.g., cellular phone, etc.) comprises a processor that is configured to execute instructions operative to reconstruct reference frames from a received video bitstream. A non-intensity-compensated copy of a reference frame of the bitstream is stored in a memory of the device and used for defining the displayable images and for on-the-fly generation of a stream of intensity-compensated pixels to perform motion compensation calculations for frames of the video bitstream.
