High Performance Digital Video Servers: Storage and Retrieval of Compressed Scalable Video
Seungyup Paek, Shih‐Fu Chang · Advances in computers · 1998
Developments in the fields of computing, computer networks and digital video compression technology have led to the emergence of unprecedented forms of video communications. In the future, it is envisioned that users will be able to connect to a massive number of distributed video servers, from which users will be able to select and receive high quality video and audio. High performance video servers will store a large number of compressed digital videos and allow multiple concurrent clients to connect and retrieve a video from the collection of videos. High performance video servers must provide guaranteed quality of service for each video stream that is being supported. The video server has to retrieve multiple video streams from the storage system and transmit the video data into the computer network. There has been a great deal of research and devel- opment in the past few years on the various issues related to high performance video servers. In this chapter, we provide an overview and snapshot of some of the main research areas that have been worked on recently. We critically evaluate and summarize the main research results. In particular, we focus on the interrelated issues of digital video compression, storage and retrieval for video servers.
