Innovative Digital Terrestrial Multimedia Broadcasting System


The seminar-presentation of the results of the selected projects for AO "Russian Railways" took place on November 22, 2018 at the center for innovative development of Russian Railways, Moscow.

A.V. Dvorkovich, doctor of technical sciences, member-correspondent of RAS, Director of Phystech School of Radio Engineering and Computer Technology of MIPT, presented the RAVIS project: "RAVIS 2.0 – Technology of digital terrestrial multimedia broadcasting and communication of VHF range and the possibility of its use for the needs of Russian Railways on the basis of the results of a comprehensive project: "Development of software and hardware for terrestrial video broadcasting systems and communication of mass and special applications using a limited frequency resource" (2015-2017).

Possibilities of applying the results of a complex project for Russian Railways

  • Video transmission during communication with the site of emergency recovery works.
  • Video and necessary information transmission on the results of infrastructure visual inspection at stations and running lines.
  • Viewing live data, statistics and the state of the infrastructure objects in real time directly on the video image during emergency recovery works.
  • Real-time information transmission about the actual whereabouts of the cargo in the railway network.
  • Construction of modern digital radio communication systems on Russian Railways.
  • Transfer and receipt of the necessary information to the passenger in railway transport in real time.
  • Creation of the "driver's assistant" system for rapid transmission of the necessary information.

Possibilities of applying the results of a complex project for Russian Railways: “SMART RAILWAY STATION BUILDING and SMART STATIONS”

  • Higher safety of the railway stations infrastructure through the system of information and notification of civil defense and emergencies.
  • Provision of a wide range of additional services at the destination, including personal security.
  • Constant interactive road information for passengers without using the Internet.
  • Enabling real-time information transmitting and receiving on railway transport, at railway stations, transport hubs and trains without using the Internet.
  • Implementation of the Instruction of President Vladimir Putin to the government of the Russian Federation together with Russian Railways to ensure the development and approval of an action plan aimed at the predominant use of domestic software by the Russian Railways.
  • Import substitution.

Possibilities of applying the results of a complex project for the Russian Railways: the transfer of images and videos

Info transfer to the driver's cab from the next crossing (in case of interference – the vehicle goes to the crossing and gets stuck in front of the approaching train). It is possible to transfer video or images from the crossing in an allocated frequency band 160 MHz for a particular train driver, and not to everyone in range.

Image/video transmission is performed on a narrowband channel from 10 kHz (slide show) to 250 kHz (full-length video).

RAVIS allows to urgently transfer video/images from the place of the train derailing through the air to the RAVIS receiver and then to the nearest Transtelecom or another operator node, and from there via optic fiber to the Situation center.

Possibilities of application of the results of a complex project for Russian Railways: single-frequency network along railways

The construction of single-frequency broadcasting networks for mobile reception along railway lines opens up unlimited possibilities of broadcasting for continuous mobile reception of various audio and video programs (for children and adults, road information, etc.). Passengers will be able to watch TV programs on the screens installed inside or listen to radio programs throughout the trip.
