GLOBAL DISTRIBUTED MONITORING

MultiProbe - global distributed monitoring and recording system

Demo access to system upon request through WEB interface
System assignment

The Cloud-based system with WEB interface is intended to provide 24/7 Monitoring, Recording, Playback, Downloading, Analyzing over the distribution of TV and radio channels in the broadcasting networks.
There is a possibility to control the broadcasting networks, as well as automation of processes related to the controlling and supervision activities of Organiztion and monitoring of Information Technology and Mass Media in terms of compliance of government legislation in the field of communication.

System is intended for:
- Broadcasters,
- Satellite and OTT operators,
- TV and Radio Stations,
- Media Authorities,
- Media Monitoring Companies,
- Press Agencies,
- Advertising Agencies,
- Content Providers and distributers.

The main tasks of the System are as follows:

- providing of continuous 24/7 monitoring of on-air television and radio broadcasting in analog and digital standards and automated notification special department or users about broadcasting interruption of obligatory public FTA TV and radio channels;

- ensuring of controlling and supervision activities held by  territorial authorities Supervision Service through the provision of program recordings; 

- receiving, collecting and structured storage of audio and video information of controlled programs to ensure the monitoring of Mass Media;

- providing of analytical data on the status of TV and radio broadcasting of obligatory public TV and radio channels on the territory of whole country on the number and duration of broadcasting interruptions that are grouped by place, time and broadcasting operator. 




Each MultiProbe server is able to receive TV and Radio channels from any type of signal, in any formats and standards. As well it is able to receive and collect SNMP data from other devices and provide this information for users in graphs and tables view.
This allows to monitor the health of other equipment and to get any other information from devices, like RF metrics for received signal, analyzing signal, and etc.

Each MultiProbe server can include a few different software modules on each site to get different tools. At this moment it has 3 modules: Analyzer, Viewer, Recorder.

Analyzer

Module that is in charge of the instrumental control of TV and radio broadcasting parameters, which allows tracing the whole signal transmission network from studio to any remote point. Module operates with any input interfaces and types of signals as well as integrates with external receiving and measurement equipment for further characteristics.
Provides instrumental analysis of AV signals and quality of digital signals of DVB-T/T2/C/S/S2 standarts, control of streaming and network QoS parameters (ETSI TR 101-290, IP statistics, meta data, EPG, subtitles, teletext and AD insertion marks), quality control of viewer perception QoE (loss of image and sound, blocking effect, frozen video and black fields, no sound, clipping of sound etc.)

Viewer

Besides the instrumental control, for users it is essential that system provides the possibility of selected audio-visual assessment of TV and radio broadcasting quality.
The system users have the opportunity of remote review and listening any selected TV and Radio channels in Mosaic view or make preview any single channel in full screen mode from any MultiProbe server and from any location. The video transmission from remote MultiProbe units is carried out in HLS/MPEG DASH formats. This module exactly resolves this task.

Recorder

It is flexible module for recording TV and radio channels which are under monitoring. It allows effectively encode AV data from SDI, Composite and transcode transport streams MPEG TS using H.264 compression algorithms. All parameters of recording for each channel can be configured individually.
2 recording modes are supported:
•     Ongoing 24/7 cyclic recording mode;
•     Cyclic recording according to schedule or task planning;
Module MultiProbe Record is fully integrated with other modules of MultiProbe system, which means that user can instantly go to the archive from any other module referring on any event in the past, and to review this video segment.
Simple export of selected video segments from the archive to the working places of users with the opportunity of transcoding to any necessary video bitrate and file size or file length and time code overlaying.

For the exact time synchronization each Probe station has a GPS module onboard.

Email and SMS notifications are available along with the wide range of options for it.
Easy integration with local Mobile Operators in any country by SNPP protocol for SMS notifications, in case of a big number of subscribers in different departments.
