A Spatial Renewal Video Traffic Model Based on Buffering Metrics

This work proposes a new method to variable bit rate video traffic model used to capture the multi-level characteristics that are significant in determining buffering requirements. While lots of the previous work in video traffic modeling has paid attention on real-time multimedia systems that of necessity engage queuing models with small buffers, there are increasing interests in awareness that high quality video is downloaded in non-real-time from a source like the Internet, and then spread at a later time in a regional environment to a very low-cost, so resource constrained devices in which smooth playback and prevention of data loss are of vital importance. This paper is focusing on the tradeoffs between the quality of video and resources´ buffers. It also provides an architecture that is directly relevant to a large group of up-and-coming applications.
