Scheduling Video Streams in Video-on-Demand Systems: A Survey

摘要

Developments in multimedia technology over the past decade has caused video-on-demand services to emerge as a new paradigm in home entertainment. Because of the large volume o data involved in the process and stringent continuity and real-time constraints, these services pose challenges that are different form the standard file transfer operations in the network. The necessity of efficient usage of scarce resources like network bandwidth and server capacity(in terms of I/O bandwidth) demands novel and easy-to-use schemes for scheduling continuous video streams.
