TeleSCREEN allows various audio and video content producers, as well as network or OTT operators to improve the quality of TV services by visual and instrumental monitoring of the quality of TV and radio broadcasting at every stage of signal delivery.

Monitoring the quality of the whole range of TV services

TeleSCREEN allows you to perform automatic monitoring of all modern video and audio signals: from content development and preparation for delivery of services to the customer. TeleSCREEN is optimized for different tasks and may be used both as part of TV studios or Head-end stations and network of the operator ensuring control over the delivery of signals to subscribers. 

Easily scaled, comprehensive approach

TeleSCREEN is easily scaled; the capacity of each system may be expanded as and when necessary, which provides for optimization of investments. System capabilities and multiple versions allow applying an integrated approach to the monitoring of TV broadcasting and increase the number of monitoring points as the network grows.  

Supports a wide set of input interfaces

TeleSCREEN system is capable of performing simultaneous analysis of a wide range of professional video and audio (SD/HD/DualLink HD/3G-SDI, DVB-ASI, IP, AES/EBU) signals, including analogue (PAL, SECAM, NTSC, FM/AM) and digital RF signals (DVB-T/T2, -S/S2, -C/C2) used in distribution network. 

Input data analysis 

Due to integrated instrumental signal analyzer, Tele- SCREEN allows not only detecting problems and informing on their occurrence, but also determining causes of oc- currence thus ensuring rapid troubleshooting.

Alerts and logging 

blems in in- put streams using audio and visual alerts, as well as pro- viding for distribution of such information to the external systems in the form of SNMP Trap or Syslog messages. TeleSCREEN system supports SNMPv2 standard (SNMP Get) for querying measured parameters as well, as modern high speed integration interface on base HTTP/JSON technology with guaranty of data delivering.

Display and recording of input signals

Display of services is carried out on several display devic- es simultaneously (including, LCD panels or monitors). In- put signals may be recorded automatically, which ensures the recording of the situation and subsequent offline anal- ysis 

Audio loudness measurement

TeleSCREEN analyzes and displays integral audio loudness (ITU-R BS.1770) for all audio tracks, and makes automatic loudness adjustments using volume correction devices ensuring higher quality of TV broadcasting.  

Monitors the quality of Internet (OTT) protocols 

CCTV monitoring of remote equipment installations using IP video cameras 

System is controlled with provided management soft- ware, and also by the multi-functional control key- board. The system also provides for remote control and visual monitoring
