Abstract (en)
[origin: WO2012008614A1] A video decoder that uses power reduction techniques is disclosed. The video decoder comprising; (a) an entropy decoder that decodes a bitstream defining said video; (b) an inverse transformation that transforms said decoded bitstream; (c) a predictor that selectively performs an intra-prediction and a motion compensated prediction based on said decoded bitstream; (d) a buffer comprising compressed image data used for said motion compensated prediction, including low-resolution data and high-resolution data, where said predictor predicts both a low-resolution data set and high-resolution data set based upon said low-resolution data using high-resolution prediction information decoded from said bitstream without using said high-resolution data.
