Optimal rate allocation for progressive fine granularity scalable video coding.

Optimal rate allocation for progressive fine granularity scalable video coding.

We examine the enhancement-layer rate allocation problem in progressive fine granularity scalable (PFGS) video coding. The problem arises from the fact that different frames in the enhancement layer have different rates in PFGS coding. A rate-distortion (R-D) function for a multiframe group is first...
