We propose a lecture-on-demand system, which searches lecture videos for segments relevant to user information needs. We utilize the benefits of textbooks and audio/video data corresponding to a single lecture. Our system extracts the audio track from a target lecture video, generates a transcription by large vocabulary continuous speech recognition, and produces a textual index. Users can sele...

In our days, the use of Internet services has become a part of every day life. The need for more advanced applications is increasing and solutions have to be provided in order to meet it. Multimedia information is constantly getting more popular. The connections’ bandwidth though is not ready yet to cope with the rising expectations of applications such as Video on Demand (VoD), which are very ...

Server bandwidth has been identified as a major bottleneck in large video-on-demand (VoD) systems. Using multicast delivery to serve popular content helps increase scalability by making efficient use of server bandwidth. Further, recent research has focused on proactive schemes in which the server periodically multicasts popular content without explicit requests from clients. Proactive schemes ...

The Video-on-Demand (VOD) service allows users to view any video program from a server at the time of their choice. Broadcasting protocols can be used to improve the efficiency of a VOD system. The Harmonic Broadcasting Protocol has been proved to be bandwidthoptimal, but it is not efficient for the local storage. In this paper, we present the Discrete Broadcasting scheme, which can intelligent...

With recent developments in technologies, video streaming becomes common on the Internet. Copyright protection of video contents is becoming essential. Thus, an RTSP-Based Video-On-Demand System with watermarking is developed in this project. The system is developed in Java. It is successfully developed with capability to stream stored and real-time captured videos. It can also save captured vi...

We propose to demonstrate a mobile server assisted P2P system for on-demand video streaming. Our proposed solution uses a combination of 3G and ad-hoc Wi-Fi connections, to enable mobile devices to download content from a centralised server in a way that minimises the 3G bandwidth use and cost. On the customised GUI, we show the corresponding reduction in 3G bandwidth achieved by increasing the...

For many applications, audio is now conveyed digitally. Video applications are following fast, particularly for videoon-demand. These digital streams require constant-rate digital channels between the source and destination, but a great number of all networks being planned today are based on the packet switched Asynchronous Transfer Mode (ATM) technology. This paper serves as an introduction to...

Video on demand (VOD) system is an electronic video-rental service over a computer network. It provides users a service to browse and watch any video at any time with VCR (rewind, forward and pause) operations. One of the requirements for VOD system implementation is to have a VOD server that acts as an engine to deliver videos from the server’s disk to users. Designing VOD server, particularly...

This paper describes a highly available distributed video on demand (VoD) service which is inherently fault tolerant. The VoD service is provided by multiple servers that reside at different sites. New servers may be brought up “on the fly” to alleviate the load on other servers. When a server crashes it is replaced by another server in a transparent way; the clients are unaware of the change o...

We focus on the problem of providing quality-ofservice guarantee, scalability, and on-demand property to video streaming systems. We propose a solution called Layered Range Multicast (LRM). LRM allows transmitting a range of data to a multicast group’s members, which helps clients who request for service at different times join a same multicast efficiently without additional server bandwidth al...
