Reduced Frame Quantization in Video Coding
We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation ...

Multiframe Error Concealment for Whole-Frame Loss in H.264/AVC
In this paper, we propose a novel error concealment algorithm for the whole-frame loss based on multiframe. In concealing procedure, besides improve the quality of the concealed l...
