Abstract

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. MPEG-4 is a widely-used streaming protocol and a MPEG-4 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 MPEG-4 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 MPEG-4 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 MPEG-4 transmission.
