Abstract
Techniques are provided for sending and receiving digital video in high-quality compressed form over a network. Such techniques may include (a) performing chroma subsampling on an original video stream to yield an altered video stream; (b) applying video compression to the altered video stream to yield a compressed base layer (BL) stream; (c) creating an enhancement layer (EL) stream based on differences between the original video stream and a decompressed version of the BL stream, the EL stream including additional chroma information, which, when combined with the BL stream, encodes a video stream that has higher chroma fidelity to that of the original video stream than does the BL stream alone; and (d) sending both streams to a receiver device across the network to enable the receiver device to generate a version of the original video stream by combining the BL stream with the EL stream's additional chroma information.
