Patent ID: 6996172

Claim:
A structure for the utilization of one or more scalability techniques operable to enhance one or more digital video frames of a base layer of a digital video system, comprising: one or more enhancement layers, wherein at least a first enhancement layer of the one or more enhancement layers is coupled to the base layer and is operable to be coupled to every other enhancement layer, and wherein each enhancement layer of the one or more enhancement layers comprises one or more enhanced frames of digital video; a first sequence of one or more enhanced frames, said first sequence operable to be enhanced by selection of one or more scalability techniques; for each of the one or more scalability techniques, a mechanism for determining a number of the one or more enhanced frames of the first sequence that correspond to a scalability technique of the one or more scalability techniques; and wherein a scalability technique of the one or more scalability techniques is selected based upon the following criteria: a motion function, a frame separation function, a visual quality gain with a SNR scalability function, and a bitrate of the enhancement layer function.
