TeleSCREEN Light


TeleSCREEN Light is an optimal solution for ensuring centralized monitoring of TV production studio complex. The system provides for simultaneous visual and instrumental monitoring of signals at every stage of signal delivery, as well as automated monitoring of studio equipment operation.

Integrated broadcast quality monitoring

TeleSCREEN Light allows ensuring simultaneous continuous monitoring at any point of the TV channel path. Simultaneous monitoring of input signal, signals from all the studio sources, output signal and signals in carrier networks has turned into reality.  

Visualization and adaptivity

All the studio signals may be displayed on one or several video monitors at the same time. Multi-window display of signals may be flexibly customized and quickly switched depending on the preferences of various users. The system allows creating a convenient workstation for both master control operator and operating personnel. 

Control of content source status

TeleSCREEN Light allows ensuring visualization of the status of broadcasting equipment on a real-time basis (Play-Out server, mixing console, video recorder, etc.). The master control operator would receive all the necessary information on all the signals used, as well as broadcast content, status of signal sources and arising emergency events on one screen. 

Ad insertion/replacement management 

TeleSCREEN Light allows analyzing and logging the passing through ad insertion points in SDI (SCTE104) and MPEG TS (SCTE35) signals. Together with the analysis of the operation status of the broadcasting server, TeleSCREEN Light provides for an integrated monitoring and logging of ad insertion/replacement.позволяет комплексно контролировать и протоколировать процесс вставки/замещения рекламы.

Alert and logging of emergency events (to be customized by user)

The system notifies via audio and video alerts upon detection of deterioration of the quality of monitored signals, as well as upon the occurrence of emergency events in the monitored studio equipment. All the detected emergency events are automatically recorded in the event log.

Remote visual monitoring

TeleSCREEN Light provides for both local and remote visual monitoring of signals. Monitoring of distributed (cloud) studio broadcasting and remote technical support to broadcasting have become a reality.

Easily scaled and multipurpose

TeleSCREEN Light may work with both one signal and dozens of signals at the same time. The capacity and functionality of the system may be expanded, where necessary, which provides for cost optimization. TeleSCREEN Light may be used not only in a fixed studio, but also as part of a TV mobile unit or small mobile studio.

Competitive product at reasonable price

TeleSCREEN Light does not require high initial costs. Given the best functionality, the cost of the system is significantly lower than those of similar products.
