Adaptive video streaming: pre-encoded MPEG-4 with bandwidth scaling

The increasing popularity of streaming video is a cause for concern for the stability of the Internet because most streaming video content is currently delivered via UDP, without any endto-end congestion control. Since the Internet relies on end systems implementing transmit rate regulation, there has recently been significant interest in congestion control mechanisms that are both fair to TCP and effective in delivering real-time streams. In this paper we design and implement a protocol that attempts to maximize the quality of real-time MPEG-4 video streams while simultaneously providing basic end-to-end congestion control. While several adaptive protocols have been proposed in the literature [28, 37], the unique feature of our protocol, the Video Transport Protocol (VTP), is its use of receiver side bandwidth estimation. Such estimation is transmitted to the sender and enables it to adapt to network conditions by altering its sending rate and the bitrate of the transmitted video str...
