FIELD: physics.
SUBSTANCE: invention discloses a method and an apparatus for encoding/decoding video, which perform transformation of at least a portion of a high-resolution video frame into a low-resolution image and a plurality of enhancement data sets. Further, the method includes encoding the low-resolution image as a primary coded picture in a bitstream format and encoding 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 mage. 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.
EFFECT: easier image processing.
