Abstract
In this paper, the scale patching technique, which is based on the traditional patching technique and using media scaling, is proposed. In our scheme, video server has scale-coded video with the size of patching window. When the patching request is issued, video server transmits and processes the scale-coded video stream by a normal-coded rate through patching channel. Therefore, the channel utilization time of scale patching channel is than general patching channel so that the availability of the total channels in video server is improved. Accordingly, the virtual patching window greater than patching window can be adopted by transmitting the scale patching stream that can play longer than ordinary patching stream in the same patching window time. According to the results of the performance evaluation by a simulation, we know that the performance of proposed scale patching technique is much superior than that of other general patching techniques.
