Appeal No. 2004-1689
Application 09/912,132
BACKGROUND
The invention relates to video decoding with reduced
computational complexity as stated in claim 1, reproduced below.
1. A method for decoding a video bitstream at a first
resolution, comprising the steps of:
producing residual error frames at a second lower
resolution;
producing motion compensated frames at the second lower
resolution;
combining the residual error frames with the motion
compensated frames to produce video frames; and
up-scaling the video frames to the first resolution.
