Abstract
In this paper, the design and implementation of a video conference rec order on an inexpensive PC is described. The recorder can simultaneous ly record several video and audio (A/V) streams in Unix file format. T he objectives of the file system design are high throughput and low lo ss rate. A hard disk device driver and a file system are modified and tuned for A/V recording. The new file system can have up to 60% perfor mance improvement over the traditional file system. Performance result s from our experiments are presented and discussed in the paper.
