Abstract
This paper proposes an enhancement layer truncation scheme for the Fine-Granularity-Scalability (FGS) video. Our target is to minimize the quality variation of different parts within each frame when the last transmitted enhancement layer is truncated according to the available network bandwidth. We propose to redistribute the bits in the enhancement layer that can only be partially kept with the available bit-budget so that it is able to cover the whole frame area to raise the quality of different parts uniformly. Simulation results confirm the effectiveness of the proposed method in improving the decoded visual quality and reducing the intra-frame quality variation.
