Abstract
A method and apparatus for encoding and decoding video performs transformation of at least a portion of a high-resolution video frame into a low resolution image and a plurality of enhancement data sets, encodes the low resolution image as a primary coded picture in a bitstream format and encodes each of the plurality of enhancement data sets as a different redundant coded picture in the bitstream format. For decoding, a decoded low resolution image and a plurality of decoded enhancement data sets are generated and an inverse transform is performed to construct a decoded high-resolution image. The primary coded picture and a redundant coded picture may be formatted according to the ITU-T H.264 Advanced Coding specification. The transform may be a polyphase or a sub-band transform.
