Stream MultiScreen is a highly effective hardware and software complex for monitoring several video and audio signal sources simultaneously in real time.

Stream MultiScreen system is designed for real time control of several video and audio signal sources simultaneously on one or several computer screens (plasmas, LCD-television sets). It allows to create random video window configurations, place audio indicators and display other informational elements on the monitor. Apart from displaying the signal, the system manages incoming video and audio signal parameters, and provides relevant messages and alerts.


  • TV-channel Master Control
  • Satellite TV apparatus rooms
  • Cable network apparatus rooms
  • IPTV network apparatus rooms
  • Studio apparatus rooms
  • Mobile TV stations
  • Control centres
  • Sport competitions
  • Concerts, mass events

Key features

  • Multiple monitors support. Vertical monitor arrangement support.
  • Signal parameters and error detection control.
  • High image quality. Resolution up to WUXGA (1920 x 1200 pixels).
  • Redundant power supply.
  • Quick video window location configuration change by pressing “hot keys” with external remote control or according to specified schedule.
  • Stream MultiScreen connection to LAN allows to join several devices in a single network and fully control them from any workstation.
  • User-friendly interface – drag & drop support, output to monitor template creation software.
  • Recording 4 channels simultaneously with 720 õ 576 pixels resolution, creating a schedule for video and audio data archive, and remote viewing option.

Monitoring features
Multiple monitors support. Up to 4 monitors (up to 2 monitors in standard configuration) connection via VGA / DVI / HDMI interface to one Stream MultiScreen device.

Vertical monitor arrangement support.
Displaying monitor resolution can reach: VGA output – 1600 x 1200 pixels or HDMI \ DVI-I (DVI-D) output – 1920 x 1080 pixels (Full HD) or 1920 x 1200 pixels (computer resolution).
Final signal image display in standard television CVBS \ S-Video \ YUV format with 720 x 576 pixels resolution.

Core graphic design features
Extremely user-friendly Stream Client Manager application allows to create window configurations on any common PC. By using simple drag/drop action, built-in window layout editor helps you quickly create a necessary configuration, including signal control parameters assignment, amount of service information supplied to user, clock, timer and sound indicators display.

  • Random video windows position and size. The maximum size a video window can reach is the full-screen monitor size. 16:9 frame ratio support.
  • Unlimited number of layers for objects layout (windows, PPM, clocks, captions etc.).
  • Brightness, contrast and saturation can be adjusted for every window separately.
  • Random audio PPM sound indicator position.
  • Random window text (title) location, font, size and colour.
  • Digital clock output with random position, font, size, colour and format of displayed data (time/date).
  • Several analog clock types.
  • Time zone adjustment for digital and analog clocks.
  • Each system graphic object can have a specified outline (width, colour) and background (colour or image from file (bmp, tga, tif)).

Controlled signal parameters

  • “Video Server” system modules log the following events:
    • Configuration change;
    • Video & Audio Loss;
    • Frozen Video;
    • Black Frame;
    • Blocking Frame;
    • GPI input change;
    • Edh-errors reports for SDI-signal;
    • Error in “continuity counter” field (for MPEG_TS source).

A schedule is composed to check the emergency alert response (with alarm analysis time span indication) with an option for custom response settings for each event.
Information in the system operation log is constantly updated and saved in client’s (operator’s) application, where it is also possible to make a query from any available “Video Server” module in order to obtain selective information at random system operation time range.

  • The system can be configured for response to any emergency alert in the following ways:
    • Visual (graphic): changing colour and frame width;
    • Sounding an alarm signal;
    • E-mailing a message to specified address.
  • Upon video and/or audio signal loss computer Sound Blaster issues an alarm signal.
