An evaluation on virtual bandwidth for video streaming delivery in hybrid broadcasting environments

Abstract

Most of the recent set-top boxes for digital video broadcasting connect to the Internet. They can receive data from broadcasting systems and from the Internet. Such hybrid broadcasting environments, in which clients can receive data from both broadcasting systems and communications systems, are suitable for video streaming delivery since they complement their demerits with each other. To reduce interruption time for hybrid broadcasting environments, I have proposed data piece elimination technique. However, the influence on interruption time of virtual bandwidth, a parameter of the technique, has not been well investigated. In this paper, I evaluate this and discuss how to determine appropriate virtual bandwidth.
