Patent ID: 8249164

Claim:
A video processing apparatus for use in a video receiver, the video processing apparatus comprising: 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 provide a control signal to the decoder indicative of a reduced-image portion of a video frame to be displayed, wherein the reduced-image portion is determined based upon a display capability including a display-window size and display resolution; wherein 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, the reference section adjacent the first macroblocks within the reduced-image portion and the reference section forming a portion smaller than the video frame, the decoding of the second macroblocks to account for motion of the images in the reduced-image portion without decoding third macroblocks in the video frame lying outside of the reduced-image portion and the reference section.
