Mobile Internet-Based Compression-Aware Scalable Video Coding - Rate Control for Enhancement Layers

The scalable video codec extension to the H.264 standard (H.264 SVC) is designed deliver the benefits described in the preceding ideal scenario. That is, it can yield decoded video at different frame rates, resolutions, or quality levels. In view of adaptive reference image of FGS (Adaptive Reference FGS, Mt-FOS) algorithm of H.264-SVC, we put forward a new algorithm called adaptive leakage predictors FGS (ALF.FGS) in this paper. ALF.FGS can not only well adapted to fluctuations in network bandwidth, but also provides greater flexibility to the macro block encoded video frame based on motion characteristics and texture characteristics of adaptive selecting a different reference macro block. Experimental results show that the ALF.FGS algorithm can effectively eliminate error at low bit rate and improve the FGS coding efficiency.
