Distributed System Architecture
One stream, multiple purposes
These three units are designed as loose-coupling architecture

Three-tier architecture (1/3)
Video input(Device/Interface)
Format(Tool/Stream Format)
HDV(1394) HD/MPEG-2TS
DV(1394) DVTS/RAW DV
WEB-CAM(USB) VLC/MPEG-4CABLE(CAPTURE CARD)
VLC/MPEG-4
*HD, DVTS, and VLC are open source software

Distributed stream compression Two compression concepts have been implemented
Client-Server basedReduces network bandwidthTransfers video stream to multi-formats(mp4,wmv,flv,mjpeg)
Server-side basedDynamically assign the video stream to suitable servers depending on loading.Compresses the video stream to a variety of bit-rates for different network bandwidth
