Fast mode selection algorithm based on derived layer

Scalable Video Coding (SVC), provides different resolutions, different video quality and different video streaming rate after once compression according to various requirements of users. The characteristic performance can solve a series of video transmission problems encountered in the current complex and heterogeneous network environment conveniently and effectively, and provide a highly efficient solution for the new video network. Because of problems such as the SVC coding efficiency in multilayer and the coding cost, the research on SVC is mainly focused on how to improve the coding speed of the algorithm (fast SVC algorithm). For the macroblock mode selection in H.264/SVC, the paper selects the fast algorithm based on the macroblock in derived layer.
