SARS: A linear source model based adaptive rate-control scheme for TCP-friendly real-time MPEG-4 video streaming

The increasing demand for streaming video applications on the Internet motivates the problem of building an adaptive rate control scheme for the time-varying network condition. The time-varying available bandwidth and latency make the real-time streaming applications difficult to achieve high bandwidth utilization and video quality at receivers. MPEGA is a widely-used streaming protocol and a MPEGA video streaming system should be able to provide an adaptive rate control mechanism to satisfy these changing conditions. In this paper we analyze the problem of transmitting MPEGA video streaming over IP network with some well-known TCP-friendly rate control protocols. This paper is focused on solving the challenging issues in application layer, compression layer to reduce the frame dropping rate. With this aim, we provide a solution called "SARS" (Smoothed and Adaptive Rate-control Scheme) in compression layer and application layer for an MPEGA video streaming system and discuss the characteristics of its components. Furthermore, we assess the effects of SARS by simulation with the well-known solution for MPECA transmission.
