Abstract:
1. A method comprising: forming a first prediction value for a first portion of an enhancement layer macroblock, representing at least a portion of a video frame within a scalable bit stream, by performing a residual prediction from a first set of base layer macroblocks; forming a second prediction value for a second portion of the enhancement layer macroblock by deriving reconstructed and upsampled values from a second set of base layer macroblocks; performing a filtering operation on a boundary between the first and second portions of the enhancement layer macroblock, wherein all base layer macroblocks are treated as inter-coded base layer macroblocks for the derivation of the reconstructed and upsampled values to form a prediction value for the whole enhancement layer macroblock, and wherein the filtering operation comprises a blending operation between the first prediction value and the second prediction value; and encoding the enhancement layer macroblock utilizing a combination of the first and second prediction values.
