Abstract
Techniques for encoding a signal are described. A signal is down-sampled to generate a version of the signal. This version of the signal is then encoded to produce a first encoded signal. The first encoded signal is then decoded to produce a first decoded signal. The second decoded signal is up-sampled to obtain a first up-sampled decoded signal. A first residual signal is obtained by taking a difference between the first up-sampled decoded signal and a first reference signal. The first reference signal corresponds to the signal prior to down-sampling. The first residual signal is encoded to produce a first encoded residual signal. The first encoded residual signal and the first encoded signal may be received and decoded by a decoder to reconstruct the signal. The signal may comprise a set of frames of video.
