Abstract

The design and implementation of a video conference recorder on an inexpensive PC is described. The recorder can simultaneously record several video and audio (A/V) streams in Unix file format. The objectives of the file system design are high throughput and low loss 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% performance improvement over the traditional file system. Performance results from our experiments are presented and discussed
