In this paper we analyze the effect of reshaping traffic using various network service disciplines on Videoon-Demand (VoD) applications. Using a client centric approach we develop a methodology based on a realtime producer-consumer framework. We present an anlytical model of client buffer requirements in presence of network delay bounds and delay jitter bounds. We show through numerical analysi...

In order to address the scalability problems of Video– on–Demand systems, several periodic broadcast schemes have been proposed that partition a video into segments and repetitively broadcast each segment on a separate channel. A new scheme is presented for the bandwidth–efficient periodic broadcast of video. The proposed scheme determines the segment sizes and their corresponding channel bandw...

Current video-on-demand (VoD) systems can be classified into two categories: 1) true-VoD (TVoD) and 2) near-VoD (NVoD). TVoD systems allocate a dedicated channel for every user to achieve short response times so that the user can select what video to play, when to play it, and perform interactive VCR-like controls at will. By contrast, NVoD systems transmit videos repeatedly over multiple broad...

Video-on-demand (VoD) streaming applications have evolved into one of the most popular types of applications on the Internet over the past decade. A great amount of research has been conducted to address the high bandwidth and stringent delay requirements of VoD applications on the video servers and the Internet. In this paper, we provide a broad survey of existing schemes and classify them int...

In this paper, we examine algorithmic issues related to the delayed multicast technique for video-ondemand delivery. We introduce the minimum total memory (MTM), minimum total traffic (MTT) and the minimum maximum memory per node (MMMN) delayed-multicast allocation problems. We examine these problems on two networks of practical interest, namely, the chandelier and the broom networks. We provid...

In this paper, we develop three explicit analytical models for evaluating the request blocking probability of movie files in VoD systems under three server selection schemes. The first is exact and the other two are based on fixed point approximations. We show that the choice of server selection schemes can significantly affect the blocking probability performance of the systems. We demonstrate...

Within this paper we propose architecture ideas of a distributed Video on Demand network which base on peer to peer technology. Each peer offers video streams to other peers and may receive a video stream from another peer simultaneously. This results in an optimization problem depending on different factors which we approximate with the help of an simulation environment. Our approach bases on ...

The current generation of mobile clients have incessant demand for services. Providing Video-on-Demand (VoD) services to these clients require a new paradigm. This paper presents an architecture for Mobile Video-on-Demand. Several schemes that reduces the load on the video server, thereby increasing the number of requests that need to be served is proposed. The Distributed Indexing reduces the ...

To simplify the process of editing interactive video, we developed the concept of “detail-on-demand” video as a subset of general hypervideo where a single button press reveals additional information about the current video sequence. Detail-on-demand video keeps the authoring and viewing interfaces relatively simple while supporting a wide range of interactive video applications. Our editor, Hy...
