Many multimedia applications rely on video streaming techniques. However, large scale video delivery is still very challenging since it requires a large amount of resources such as storage space, network bandwidth and I/O bandwidth. In this paper we propose a proxy-assisted periodic broadcast architecture for video delivery to a large number of clients over the Internet. Our video delivery tech...

Many multimedia applications rely on video streaming techniques. However, large scale video delivery is still challenging since it requires a large amount of resources. In this paper we propose a proxy-assisted periodic broadcast architecture for video delivery to a large number of clients over the Internet. Our video delivery technique is based on a combination of periodic broadcast by central...

A novel and simple approach for defining end-to-end quality of service (QoS) in video-on-demand (VoD) services is presented. Using this approach, we derive a schedulable region for a video server which guarantees end-to-end QoS, where a specific QoS required in the video client translates into a QoS specification for the video server. Our methodology is based on a generic model for VoD services...

This Video data is stored in a video server for delivery to multiple receivers over a communications network in a traditional video-on-demand system. The hardware in this video server has the following limitations: 1) the maximum storage capacity, and 2) the maximum number of video sessions that can simultaneously be delivered. We propose a novel Adaptive-Multiple-VIdeo-Server -Architecture (AM...

ÐIn conventional video-on-demand systems, video data are stored in a video server for delivery to multiple receivers over a communications network. The video server's hardware limits the maximum storage capacity as well as the maximum number of video sessions that can concurrently be delivered. Clearly, these limits will eventually be exceeded by the growing need for better video quality and la...

Video-on-demand (VoD) systems have traditionally been built on the client-server architecture, where a video server stores, retrieves, and transmits video data to video clients for playback. This paper investigates a radically different approach to building VoD systems, one where the server, and hence the primary bottleneck, is completely eliminated. This server-less architecture comprises homo...

Advances in storage technologies are making it feasible to design video servers that are capable of supporting continuous, real-time delivery of multiple video streams simultaneously. One of the major design considerations for a large-scale video server is scalability, to admit and service thousands of subscriber requests simultaneously. In this paper, we deene and formulate various policies th...

The server array is a novel video server architecture based on partitioning each video over multiple server nodes, thereby achieving perfect load balancing for any demand distribution. We discuss the main design issues, compute the buffer requirements at the client, and compare the reliability of different video server architectures.

Video servers are important for applications which make use of digital video. The video servers should provide better functionality than most of today’s video servers offer, – e.g., support of flexible and instant user interactions, delivery of multiple video formats and support of virtual video documents. In this paper we discuss the requirements that video servers should fulfill and we descri...
