This document discusses key areas in streaming video over the internet including video compression techniques, application-layer quality of service control, continuous media distribution services, streaming servers, media synchronization mechanisms, and protocols for streaming video. It covers nonscalable and scalable video encoding, bandwidth and delay requirements, congestion and rate control, error control, streaming server components, and protocols like RTP, RTSP, and SIP. The document also outlines future directions in these areas like improved video compression schemes, evaluating rate control effectiveness, building scalable distribution infrastructure, and enhancing streaming server and protocol functionality.
