THPSC31	Media Server for Video and Audio Exchange between the U-70 Accelerator Complex Control Rooms	software, controls, real-time, operation	386
	I. Lobov, V. Gotman IHEP, Moscow Region, Russia
	The media server was developed that implements the exchange of video and audio streams between control rooms for U-70 technological subsystems. Media server has the possibility of making changes into the intermediate video images to embed current technological information. The media server is implemented as a set of threads of execution, one for each video format conversion module. The media server is a chain of successive transformations of video and audio streams from one format to another: H264 - Y4M - Theora formats for video, PCM - Vorbis formats for audio. The final video and audio streams are encapsulated into the OGG container stream which is translating into the local network. OGG container has been chosen because of its completely open, patent-free technology and full support in HTML5. Any Web browser with full HTML5 support may be used as OGG stream consumer. The browser client program has written with tag "video" utilization. This allows for client to work on different platforms (Linux, Windows) and get rid of third-party video plug-ins.

	The paper describes our efforts to organize centralized access to IP-devices of specific types. Each device includes proper embedded web-server and is connected to an accelerator department network. Today there are tens of the devices are used to give pictures online. A device access is carried out by user understandable device names with the aid of accelerator department web-server.

	The software which allows controlling the whole installation to measure electric fields in the linear structures has been developed. The installation consists of linear structure, step motor drive, motor controller, a probe which moves on the string throw the structure to perturb the field to use the perturbation measuring method, network vector analyzer and the PC. He software interface is user-friendly, user only needs to write down the length of the structure, a desired step of the probe and push the start button. As a result user can obtain the picture of electric field on the structure axis. It is possible to choose between two measuring methods: by S11 of by S21.
