ActiveSTB: Scalable Scheme Over Wireless Networks

Quality of streaming service is determined by bandwidth constriction and error rate of link in wireless environments. The layered video coding provides attraction for streaming service at wireless environments through adaptation of streaming size. However, these dependency also increases the possibility that streaming data are thrown out even though they are transmitted successfully. It wastes a lot of link bandwidth and drops the efficiency of transmission. To understand the structure of layered streams increases the performance of layered video streaming. In this paper, we proposed the active streaming schemes of layered video streaming depending on the available bandwidth. The intermediate nodes figured out the structure of layered video streaming and then change the format of scalable streaming scheme. The complicated relationship between layered streams increases the availability of layered stream, but also risks to waste the transmitted layered streams. Additionally, we added the comparison between simple referred layered streams and complicated layered streams.
