    • A video processing apparatus, for use in a video receiver, includes a decoder configured to decode encoded video information into decoded video information and to output the decoded information, and a configuration module coupled to the decoder and configured to a provide a control signal to the decoder indicative of a reduced-image portion of the video frames to be displayed, where the decoder is configured to respond to the control signal by decoding first macroblocks of the video information within the reduced-image portion and second macroblocks of the video information, in a reference section, adjacent the first macroblocks to account for motion of the images in the reduced-image portion without decoding third macroblocks lying outside of the reduced-image portion and the reference section.
