Technical and installed realization

Technical and installed realization

• The technical decisions, for providing
  scientifically-organizational actions in the JINR
  House for International Conferences (HIC or
  Russian abbr.DMS), are caused by modern
  requirements to information display projection
  tools, a sound-technical complex, presence of
  wire and wireless local networks with output in
  Internet and system network video streaming.
• At the first stage, 2 halls for meetings in the
  JINR DMS are equipped with the projection,
  presentation, video and switching devices. When
  developing the project, functionality of the
  creation of centralized management of the complex
  was considered.
• The primary goals of the development of the
  project were as follows
• 1. High quality displaying of information on the
  projective equipment
• 2. Operation reliability and simplicity
• 3. Opportunity of switching a large number of
  sources and signal types
• 4. Scaling and escalating of the system during
  the operation
• 5. Re-equipment of a sound part of the complex
• 6. Promotion of Internet-broadcasting and
  streaming in a LAN
• 7. Organization of a protocol audio- and video-
  record
• 8. Wireless access to network and Internet, based
  on Wi-Fi technology

Switching features of the projective part

• Special feature of the project is the opportunity
  of wide functional purpose of the equipment, and
  as compatibility with the video standards 720p
  and 1080i/p when displaying visual information on
  video projector Sanyo PLC XP-55 with a light
  stream 5500ANSI Lm in the main hall.
• For high-grade use of the video projector, in
  system applied for increasing number of lines
  images the scaler/switcher with switching
  signals without undermining synchronization
  Kramer VP-724DS, allowing to increase twice the
  number of lines in a standard signal is applied
  in the system.

Sound subsystem

• At the first stage, a digital microphone UHF
  system Behringer EW165-G2 Evolution, a wire
  microphones Behringer EW135, and a
  compressor-gate (DBX) with association of
  microphone channels, maintenance a uniform level
  of preamplification, and a system of feedback
  destroyer (DBX) have been installed.
• The sound amplification part, in which now all
  loudspeakers are connected in parallel, without
  division into the left and right channels. After
  the modernization of the switching infrastructure
  and use of the new amplification equipment,
  there is a possible to have a stereophonic sound.
  
• The main task now - installation of the main
  mixer, with functions of creation the groups of
  signal sources and their addressing, and digital
  input/output through interface FireWire. It will
  allow one to make a protocol digital record of
  audio materials into PC without analog-digital
  transformation, that considerably improves the
  quality of these data.

Network streaming and storing

• The Internet streaming system, under MMS
  protocol, based on Windows Media 9 technology and
  Windows Server 2003 Ent.
• The announcement address - mms//video.jinr.ru or
  http//video.jinr.ru/conf.asx.
• Based on Windows Media 9, because some important
  moments like administration and quality aspects
  are better realized in it.
• Integration of this service into OS on the client
  side and support, including, under OS Linux,
  speaks about opportunity in the future to make
  migration to version 10.
• Access to video stream is possible through the
  JINR Administrative Information System located at
  the URL http//adm.jinr.ru. In case of
  interdiction in the JINR LAN Multicast traffic,
  the technology of video stream transfer from a
  server to client Unicast, establishing some
  restrictions on the high-speed parameter under
  standards in 351 KBit/sec, is accepted.
• The second part - organization of the automated
  system of recording, archiving and indexating
  video- and audio- streams with creation of a
  multimedia database. It is caused by the
  requirement to the legal organization and
  carrying out scientific and administrative events
  and conferences. Access to the created archive is
  regulated, including through a corporate
  information system. In the future it will allow
  one to create evident information materials on CD
  or DVD disks after the conference.

Conclusions a multimedia infrastructure is
realized at JINR

• Stage I
• 2 halls for conferences at JINR DMS are
  equipped with a projective, video and switching
  devices, with opportunity of creating a
  centralized operating system
• Internet-streaming server, based on MMS protocol,
  Windows Media 9 technology and Windows Server
  2003, is installed and put into operation
• Stage II
• Organization of an automated system of capture,
  compression, archiving and indexating of video-
  and audio- streams with creation the media
  database
• Organization of authorized access to the created
  archive, including through a corporate
  information system
• Stage III Status and perspectives
• Development and introduction in HIM DMS of
  uniform multimedia infrastructure on the basis of
  a control system and distribution video and audio
  streams
• Opportunity of participation of remote attendees
  of symposia through a system of video
  conferencing and/or a space bridge during the
  passing the sessions
• Integration of all presentation equipment
  sources of video/audio signals, information
  display tools, switching equipment, a
  congress-system and sound subsystem will make
  on-line operated infrastructure
• Introduction of corporate media culture, with
  creation of hi-tech rooms and halls for seminars
  and symposiums, with integration of services of a
  multi-service data transmission network.
