A high performance video server for karaoke systems

Abstract

A high performance and low cost video server architecture is proposed for karaoke systems which can store more than 200 Gbytes of video and support up to 30 concurrent users simultaneously. Moreover, a novel caching strategy, called head caching, is proposed which can significantly reduce the initial delay. With this strategy, the initial delay can be dramatically reduced without increasing the cache size. Besides, using head caching scheme, the proposed system can act as a general video server which can support fast-forward, rewind, and dynamic panning controls.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
