Title:
METHOD AND APPARATUS FOR REDUCED RESOLUTION UPDATE VIDEO CODING AND DECODING
Document Type and Number:
WIPO Patent Application WO2006039382
Kind Code:
A3
Abstract:
There are provided encoders, decoders, encoding methods, and decoding methods for video signal data for an image block. An encoder for encoding video signal data for an image block includes a Reduced-Resolution Update (RRU) downsampler (515) for downsampling a full resolution prediction residual using data from at least one neighboring image block to form a low resolution downsampled prediction residual for the image block.
