Stony Brook Video Server (SBVS) is the first and probably only LAN-based distributed video server that provides end-to-end performance guarantee from the server's disk subsystem, through the LAN, and to the client machines' display. The current prototype, SBVS-II, runs over a multi-segment Fast Ethernet LAN. That is, the video server and its clients can sit on different Ethernet segments and the video playback is still guaranteed to be smooth. SBVS-II is built on top of an off-the-shelf Pentium 100-MHz machine, and is capable of delivering up to 45 MPEG-1 streams (1.5 Mbits/sec) over a 100-Mbps Fast Ethernet. It currently supports automatic acquisition and indexing of TV programs, and provides keyword-based accesses to video archives.
Currently we are building the next-generation of SBVS that features
scalable PC cluster hardware and
automatic fault tolerance across disk and node failures. In addition,
we are building a video editor called Zodiac
for digital video authoring and acquisition, and a set of video access
mechanisms based on captions, texts from
automatic speech recognizers, and high-level video units such as shots/scened
using audio-aided video
parsing.
