Detector for DVB TS Errors

MultiScreen allows building Monitoring Solution without visualization of all TV channels. 

In this case all TV and Radio controlled channels will be displayed as "Cells" in State Panel tool - MultiMonitor. 

Also, any channel can be visualized on Penalty Screen in manual mode (according to selection, done by Operator) or in automatic mode (in case of Error Detection). 

In such configurations main work is being done by remote application MultiMonitor, which receives information about controlled TV channels from the servers.  This functionality is unique and can significantly optimize the task of monitoring of large number of TV channels.

Supported TS inputs: 

Stream MultiScreen server represents an effective media platform, which provides simultaneous visual and instrumental control of unlimited number of TV- and Radio- channels. The number of physical inputs per 1 server depends on the installed input card:

  • IP/Ethernet (ETSI TS 102 034). MPEG-2 TS (ISO/IEC 13818-1), MPTS or SPTS
  • DVB-ASI (ETSI EN 50083-9). Bitrate range 0..214 Mbit/s;
  • DVB-T/T2 (ETSI EN 300 744, 302 755);
  • DVB-S/S2 (ETSI EN 300 421, EN302-307, EN301-210);
  • DVB-C/C2 (ETSI EN 300 429 Annex A/B/C);
  • HLS (HTTP Live Streaming Monitoring); supports encrypted streams

Input video formats: 

  • MPEG-1 (ISO/IEC 11172-1);
  • MPEG-2 (ISO/IEC 13818-1);
  • MPEG-4.2 (ISO/IEC 14496-2);
  • MPEG-4.10 (H.264, ISO/IEC 14496-10).
  • HEVC (ITU-T H.265 High efficiency video coding) 

Input audio formats: 

  • MPEG-2 Layer II (ISO 11172-3);
  • Dolby Digital (E-AC3, AC-3, ATSC A.52b);
  • AAC/ADTS/LATM/ADIF (ISO/IEC 13818-7, ISO 14496-3);
  • AES SMPTE 302M

Supported external events' notification:

  • SNMP Trap (RFC 3411-3418, STD0062);
  • SNMP Get (RFC 1155, RFC 1212, RFC 1213, RFC 1157, RFC 3411).

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

  • On-screen Visualization Alerts 
  • Audio Alerts
  • MultiMonitor Alerts(Client application) 
  • SNMP traps
  • Email sending

Free of charge client application MultiMonitor provides interface for work with MultiScreen database and allows controlling state of all parameters for all deployed MultiScreen servers.  In some particular configurations MultiMonitor also allows dynamic alteration of the set of channels, which are visually monitored on LCD panels. This unique functionality allows solving problem of monitoring of large number of channels with minimal effort. While operating in configuration mode, client software MultiMonitor allows controlling all available signal sources at remote MultiScreen servers: cards’ inputs; IP interfaces, including actual PAT, PMT and SDT tables. Using special set of parameters, built-in editor can create new configuration for displaying of selected channels in a matter of couple clicks.

Database View - all Events and Errors from MultiScreen Detectors are saved in database.
