Design and implementation of adaptive scalable streaming system over heterogeneous network

Abstract

Distribution of multimedia content through the internet has gain popularity with the advancement of multimedia technology through software application with different transmission capabilities. Current conventional system implementation works perfectly for a guaranteed network bandwidth. However, when the packet experience losses due to drop in bandwidth, it could not preserve an acceptable video quality over the heterogeneous network. Thus, if the bandwidth could be determined in real-time, an application that controls the scalability of video stream sent over the channel can be used to control the video quality. This is done by reducing the bit-rate of the video to be sent according to current available bandwidth. In this paper, a scalable video streaming system with automate bandwidth control over heterogeneous network, using spatial scalability approach and end-to-end available bandwidth estimation are designed and implemented. Distribution of multimedia data streaming would be improved without any jitter and could fit to any devices with various performance capabilities.
