Multichannel instrumental monitoring system A unique highly scalable solution that allows by relatively modest hardware, human and financial resources to solve serious problems of monitoring and control.
Multi-channel Instrumental Monitoring System Stream MultiScreen 5.0 Stream MultiScreen software is intended for simultaneous visual and instrumental monitoring of multiple video and audio sources in real-time. Having been based on successful combination of versatile features including multi-channel and multi-format abilities with high-level reliability, Stream MultiScreen 5.0 system has been implemented in the projects of the largest Satellite and Cable operators and TV Channels, OTT operators.
Input signals ÎÎ DVB T2-MI Streams (Option: can be monitored using Stream Labs’ DVB T2 MI splitter); ÎÎ DVB-ASI; ÎÎ HLS (HTTP Live Streaming Monitoring); ÎÎ SDI-(HD,SD) (PAL, NTSC); ÎÎ Composite (NTSC, PAL, SECAM);

The support of H.264 video and AAC audio standards: ISO/IEC 13818-7 (AAC with ADIS and MP3 audio streams; transport syntax), ISO/IEC 14496-3 (AAC with ÎÎ Coming soon: RTSP, HSS. LATM transport syntax), MPEG-1 (ISO/IEC 111722), MPEG-2 (ISO/IEC 13818-3), AC-3 (ATSC A.52b);
all these sources can be combined in one server.

Client’s application Stream MultiMonitor The quantity of channels provided by operators is constantly growing. As a general rule, the Satellite, Cable or OTT operators have a limited space for monitoring system. And while the channels’ quantity grows, the operators need more displays and racks, and the most important issue - the dramatic space extension.
MultiMonitor allows to control instrumentally the quality of any number of channels in 1 system, that leads to less required space, less personnel, « « Stream less money for total upgrade of the monitoring system and no need in total reconstruction of the studio!
Client server architecture The number of servers connected to 1 Stream MultiMonitor client application is unlimited. Operating in configurator mode, the client software Stream MultiMonitor allows to control all available signal sources on the remote Stream MultiScreen servers: cards inputs, IP-interfaces including actual PAT, PMT and SDT tables. Using special parameters set, build-in editor can create the new configuration for selected channels displaying in a couple of clicks. Automatically created configuration is available for manual editing then. The standard 1000 mbps network adapters are used for operations with IP (Ethernet) MPEG TS. The number of simultaneously decoded and displayed programs is limited only by server’s performance. The current version of the software has three modes of the core processing of MPEG TS transport streams: ÎÎ Full decoding of transport steams, visualization and analysis of selected parameters. Depending on server configuration it is possible to process up to 50 video channels per server; ÎÎ Full decoding of transport steams and analysis of selected parameters without visualization. Depending on server configuration it is possible to process up to 100 video MPEG TS channels/server.
ÎÎ Decoding of transport steams based on master frames and analysis of selected parameters. This approach allows to make the server processing the maximum number of channels (100-150 channels/server) with no affect to the process of parameters analysis.
of unlimited number of channels
Built-in editor supports the following features: ÎÎ Free positioning and size of video windows. The maximal size of video window is the size of the screen. Supports 16:9 and 4:3 aspect ratio. Automatic definition of aspect ratio for transport streams; ÎÎ Free positioning of audio PPM indicators (vertical, on the right, on the left, horizontally, over the video or outside of it); ÎÎ Any position of text in the window, size, color and transparency; ÎÎ It is possible to automatically extract program names from PAT tables for transport streams; ÎÎ Use any number of layers while placing objects (video windows and signatures, audio PPM, clocks (analog, digital), automatically updated text signatures etc.); ÎÎ It is possible to set a border (thickness, color) for any graphic object of the system.
Operator’s workplace - a centralized system of visual and audio control of alarm notifications (MultiMonitor client software)
Server N* *Unlimited number of servers.
The system logs all warning events to the database built on Microsoft SQL Express and provides the network services for quick search of the events by means of various filters. The list of the monitoring parameters and the correspondent threshold values are set to every channel separately. It is also possible to configure the graphical (video window frame width and color) and audio indication of the warning event and assign the priority for event types. One can set up the logging of the warning events info to the database with no indication at all.
Free of charge client application Stream MultiMonitor provides the interface for working with Stream MultiScreen database allowing to control the state of all monitored signal parameters for all available Stream MultiScreen servers. In some particular configurations MultiMonitor also allows to dynamically change the set of the visually controlled channels on LCD panels. Being unique this functionality allows to solve the problem of monitoring of the large number of channels with minimum efforts.
Displaying the Results of Monitoring Stream MultiScreen 5.0 provides quick switching between early prepared configurations via the Stream MultiMonitor client software using special programmed keyboard. The keys of the keyboard can be programmed for switching the particular channel to the full screen mode, getting channel audio and execution of the following commands: back to the original configuration, displaying signal source info, reset of warning events history, etc. Displaying of signal sources info is additional convenient function, that allows to get an exhaustive information on the visualization objects (service numbers, program names, PID of elementary streams, video and audio codecs names, video stream resolution and scanning type, current frame bitrate, transport bitrate).
