Date: 14/07/2009 A Distributed Architecture for Real-Time High Resolution Video Streaming TDW Teams Presenter : Yi-Hsuan Chen Contact : lsi@nchc.gov.tw National Center for High-performance Computing, Taiwan
Outline • Introduction • Distributed System Architecture (Three units) • Real-Time Video Streaming Case • Conclusions
Introduction Specific device, stream formats, resolution
Distributed System Architecture These three units are designed asloose-coupling architecture One stream, multiple purposes Image Processor Presentation unit Capture unit
Three-tier architecture (1/3) Capture unit Image Processor Presentation unit *HD, DVTS, and VLC are open source software
Three-tier architecture (2/3) • Stream Receiver :VLC + FFMPGE • Image Processor : stream clipping image processing image management • Image Navigation: security control Capture unit Image Processor Presentation unit
Three-tier architecture (3/3) Capture unit Image Processor Presentation unit • Can view the video from web browser or standaloneversion • The historical monitoring window
Distributed stream compression • Two compression concepts have been implemented • Client-Server based • Reduces network bandwidth • Transfers video stream to multi-formats(mp4,wmv,flv,mjpeg) • Server-side based • Dynamically assign the video stream to suitable servers depending on loading. • Compresses the video stream to a variety of bit-rates for different network bandwidth
Distributed stream compression • Native VS With compression concepts
Real-Time Video Streaming • Ecological Observation in Ken-Ting
Real-Time Video Streaming • Ecological Observation in Lanyu
Ecological Observation in Ken-Ting View on iPhone web-based presentation interface of four underwater cameras HDV stream of National museum of marine biology and aquarium (Taiwan)
Conclusion • Has been proofed in real time high-resolution ecological observation • Plug and Stream • Loosely coupled architecture, easy to scale-up • Support multiple streaming methods • Based on open source software, no hi-end hardware required.
