	The dispatching system for audio and video exchange between various U-70 technological subsystems has been developed. The system architecture employs the original approach to the online streaming using the method of progressive download over HTTP. The system can be built on the basis of any one-pass decoding media container. Ogg format with Theora/Vorbis codecs has been chosen as an appropriate container. The system is designed as a distributed software complex and consists of several executive components: Retransmitter, a number of Media Stream Coders and a number of clients. All the components can run either on separate computers or on the same computer. Media stream Coders consume streams from media sources, turn it into Ogg stream and send it out to Retransmitter. The possible media sources are: IP-cam, web-cam, computer screen along with microphone. A client is able connect to Retransmitter using any web-browser with Ogg Theora/Vorbis support. The range of values 250-350 ms has been achieved for the latency between real action and client video. The developed software is a framework for diverse media exchange systems that could be built on it's basis. Several possible applications are discussed in the scope of the U-70 Accelerator Complex technological needs. This could play an important role in personnel safety system while perform maintenance tasks in an extreme work environments such as the Beam Channel.

The dispatching system for audio and video exchange between various U-70 technological subsystems has been developed. The system architecture employs the original approach to the online streaming using the method of progressive download over HTTP. The system can be built on the basis of any one-pass decoding media container. Ogg format with Theora/Vorbis codecs has been chosen as an appropriate container. The system is designed as a distributed software complex and consists of several executive components: Retransmitter, a number of Media Stream Coders and a number of clients. All the components can run either on separate computers or on the same computer. Media stream Coders consume streams from media sources, turn it into Ogg stream and send it out to Retransmitter. The possible media sources are: IP-cam, web-cam, computer screen along with microphone. A client is able connect to Retransmitter using any web-browser with Ogg Theora/Vorbis support. The range of values 250-350 ms has been achieved for the latency between real action and client video. The developed software is a framework for diverse media exchange systems that could be built on it's basis. Several possible applications are discussed in the scope of the U-70 Accelerator Complex technological needs. This could play an important role in personnel safety system while perform maintenance tasks in an extreme work environments such as the Beam Channel.
