Abstract
Input digital frames may be down-sampled to create one or more base frames characterized by a lower resolution than the input digital frames. Enhancement information corresponding to a difference between pixel values for the one or more input digital frames and corresponding pixel values of up-sampled versions of the one or more base frames is then created. The one base frames are encoded to form a set of base data and the enhancement information is encoded to form a set of enhancement data. The base data and enhancement data may then be transmitted over a network or stored in a memory.
