Stream MultiScreen 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;

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.

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.

Video inputs (BNC)

  • Composite version – up to 24 (multiple of 4) Composite video inputs (525/60 (NTSC), 625/50 (PAL), 625/50 (SECAM));
  • SDI version – up to 16 (multiple of 8) auto-detectable Composite video inputs (525/60 (NTSC), 625/50 (PAL), 625/50 (SECAM)) or SD-SDI (SMPTE 259M-C-1997 standards).

Audio inputs (RCA)

  • Composite version – up to 24 (multiple of 4) analog stereo channels;
  • SDI version – up to 16 (multiple of 8) analog stereo channels and/or embedded SD-SDI stereo channels (SMPTE 272M & ITU-R BT.1305). Signal source selection: analog stereo sound or embedded SDI with stereo pair selection option.

MPEG TS (SPTS/MPTS) (Ethernet 100/1000 Mbit/s speed)

  • Incoming signal: IP multicast groups, containing MPEG-2 single-program transport stream with TV-programs compressed to MPEG-2 and MPEG-4 / H.264 standards. The number of simultaneously displayed channels is limited only by server processing power.

Video outputs (several combinations available)

  • VGA output – 1600x1200 pixels or output;
  • HDMI \ DVI-I (DVI-D) output – 1920x1080 pixels (Full HD) or 1920x1200 pixels (computer resolution);
  • CVBS \ S-Video \ YUV output (RCA).

Audio outputs

  • One of the monitored audio channels can be played through the device sound card (miniJack Stereo).
