چکیده

Digital video recorders (DVR) such as TiVo (Tivo, 2005) are changing the way TV is being viewed. The ability to intelligently record content and provide an easy use play-back facility has meant that no longer is the viewer restricted to the TV broadcaster's schedule, but can now watch the program at anytime (after broadcast) with the addition of commercial skipping features as well as the typical VCR functionality to which most people are accustomed. The focus of this research is to extend the abilities of DVRs by removing the necessity for local storage, and replacing it with an alwaysrecording global storage. With such an approach, users of the system would no longer need to be sitting in front of their DVR to view a stored file, but instead would retrieve the object from a local video server over a high-speed Internet connection. In doing this, globally broadcast TV content could be available to users on-demand. There are a number of challenges that need to be overcome when designing a TV on-Demand (TVoD) system. Issues such as (i) Latency; clients will not be satisfied if the video does not begin streaming almost immediately, (ii) Reliability; the quality of the delivery stream should be consistently high, jitter and quality degradation are undesirable, (iii) Content Control; ensuring that Digital Rights Management infringements cannot occur, (iv) Resource Management; due to the size of these high-quality video files, operating and deployment costs for the system need to be monitored to ensure the system is operating as efficiently as possible. The primary focus of this research is the efficient management of resources when providing TVoD services. It is believed that resource management will become an important aspect of video delivery in the future, as the expected quality of video objects Interactive Technology & Smart Education (2006) 1: 31-44 © 2006 Troubador Publishing Ltd.

Towards Self-organizing Distribution Structures for Streaming Media

Efficient multi-receiver delivery of video data over computer networks, such as the Internet is still challenging, due to heterogeneity in involved network technologies, end-node capabilities and receiver preferences. While adaptive and scalable video encoding can solve many of the problems caused by heterogeneity, media gateway systems are needed for performing video filtering and transformati...

Stochastic Fair Aggregate Rate Control: Practical Traffic Management for Efficient and Robust IP Networking

The robustness of the Internet today depends upon the end-to-end congestion control mechanisms of TCP. As use of non-TCP applications such as streaming media and network games grows, the potential for unfair network resource allocation and the threat of congestion collapse increase. The Internet needs a practical solution to protect well-behaving flows from misbehaving flows and avoid collapse....
