System-Level Issues for a Multi-Rate Video VOD System
نویسنده
چکیده
This document describes system-level issues for incorporation of multi-rate video into a videoon-demand system. The issues are broadly separated into two classes: rate negotiation, involving selection of a rate at which the requested video will be provided, and rate delivery, involving delivery of the coded stream to the user. Requirements of the server, the network, and the set-top box are developed, and are shown to be interrelated for design of an efficient system. Additionally, constraints are imposed on the video coding algorithm. Specific research topics for further investigation are proposed.

A Hierarchical Video-on-Demand System for ATM Networks
Video-on-Demand (VOD) is expected to be the key residential service in the near future. A VOD system consists of three components: the VOD server, the transport network, and the end user. In this paper, we focus on the design of the network module of a VOD system. We propose a hierarchical VOD network structure which can be used to achieve a low cost, high performance, high scalability, and hig...
متن کاملTraffic Modeling and Provisioning of a P2P-based VOD Architecture
Building a scalable video on demand (VOD) architecture is essential for the optimization of the VOD service cost and to support a very large VOD content library. The peerto-peer (P2P) VOD architecture works towards achieving this goal, by distributing the video files to the user's set-top boxes at the network edge. The details of such system, however, including numerous operational issues remai...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
