In this thesis on Scalable Internet Video-on-Demand Systems solutions are provided that allow scalable streaming in today’s Internet. These solutions allow the optimization of existing Videoon-Demand applications, as well as the integration of new mechanisms in the video streaming area. With the increasing popularity of video and audio data in packet switched networks and the lack of quality of...

The paper presents a simulation study of CANDID, a video-on-demand server. CANDID is distributed, scalable, cost-eecient server capable of providing service to hundreds or thousands of clients. The server consists of several processing nodes with several disks each, connected in shared-nothing manner. Compressed movies are declustered across all disks of the server. Movies are read by fragments...

This paper reports on our progress in developing an advanced video-on-demand (VOD) testbed, which will accommodate various multimedia research and applications such as Electronic News on Demand, Columbia’s Video Course Network, and Digital Libraries. Two different prototypes have been completed. The first generation of the testbed was based on a constant-bit-rate (CBR) video server utilizing Et...

Many educational institutions have a substantial personal computer (PC) network that can be adapted to provide digital video on demand, as well as PCs that can be used as video on demand clients. To gain insight into the issues involved in using this technology in an educational environment that relies heavily on video, a simple, low cost video on demand system was installed in the Visual Arts ...

Despite the amelioration in communication technologies, the server network I/O bottleneck remains a severe obstacle in video-on-demand applications. All bandwidth-sharing techniques, proposed to overcome this, assume videos to be requested in their entirety. In this paper, we extend the video-on-demand delivery problem so that it allows users to request parts of video and be able to receive the...

In the next generation network (NGN) environment specific consideration is on bandwidth minimization, because this reduces the cost of network. In response to the growing market demand for multimedia traffic transmission, NGN concept has been produced. The next generation network provides multimedia services over high speed networks, which supports DVD quality video on demand. Although it has n...
