To convert a compressed video sequence to a lowerresolution compressed video, one typically needs to decompress the original sequence, down-sample each frame, and recompress it. I...

—Reduced Resolution Update (RRU) video coding provides a better compression performance than H.264/AVC does. It is implemented by encoding the predicted residuals after downsampl...
