2 in 1 - multiviewer & instrumental monitoring system for TV and Radio channels

Stream MultiScreen system is intended for simultaneous visual and instrumental monitoring of multiple video and audio sources in real-time using one or several LCD-panels in poly-screen mode.

Having been based on successful combination of versatile features, which include multi-channel and multi-format abilities and high-level reliability, MultiScreen system has been implemented in the projects of largest Satellite and Cable Head-End operators, TV Channels and OTT operators.

All measurement errors and clearing are signaled via multiple communication routes:

  • On-screen Visualization Alerts
  • Audio Alerts
  • Visual Alerts in MultiMonitor(State Panel)
  • SNMP traps
  • Email sending


Integration of visualization with external devices in accordance with TSL UMD v.5.0 Protocol is implemented.
Visual object for UMD, which includes 2 indicators and text box, can be added to visualization mosaics. 
Control of UMD is carried out by external devices (like TSL TallyMan 
controller) in accordance with TSL UMD v.5.0 Protocol.

Integration with Compliance Recording system - MultiRec

Stream MultiScreen can work jointly with system MultiRec, crafted for compliance recording. Database for alerts, generated by MultiScreen has been integrated with archive of recordings, produced by MultiRec; and allows downloading of fragments of archive, matching to alerts, straight from MultiScreen application in one click. You may view them later on at your convenience.
