With Elecard being an exhibitor at the 2020 NAB Show, it is important to know that the company took part in the large-scale project on content preparation and broadcasting of 12 channels in the Moscow underground trains. The Moscow Metro is the backbone of the Moscow transport system. It consists of 15 lines and 269 stations, on which over 12 thousand trains are passed daily. There are 6200 video screens installed in the metro carriages, which broadcast TV channels, information videos, and commercials. The monitors are designed for a large audience: over 7 million people use the metro every day.
Elecard, SoftLab-NSK, and Stream Labs developed and implemented the hardware and software complex for preparation, broadcasting, and monitoring of TV channels in metro trains of 12 lines. This solution is based on the transcoder Elecard CodecWorks and high-density servers. CodecWorks supports H.265/HEVC, which is especially important in this project, as the communication bandwidth in the rolling stock is limited. HEVC allows broadcasting video of higher quality because of a higher compression, as opposed to the AVC format. The solution guarantees stable broadcasting as it includes redundancy of all system components. If an error occurs, the schema will automatically switch to the reserve source, and viewers will not notice a failure.
The Stream Labs provided the solution for the head-end station monitoring. The technologies of the SoftLab-NSK were used to implement the playout system. The solution supports targeted advertising based on content duration. A playlist with a specific set of informational videos and commercials is prepared for each subway line. The solution is integrated with external systems of advertising content delivery.
“Metropolitan is a unique facility that has its own specifics in terms of standards and operation. It is important to understand and consider this in our work. We provided exclusive technical support during testing and implementation of the solution,” said Nikolay Milovanov, Elecard CEO.“We came up with the task to implement broadcasting of media content with targeted advertising in Moscow Metro. We turned to Elecard with a request to provide a high-quality software solution. The implemented solution allows us to broadcast commercials as well as sports and cultural events. On behalf of the company I would like to express my gratitude to Elecard employees for the project implementation and professional support at all stages of the system integration,” comments Maxim Shemegon, Development Director of the Moscow Metro State Unitary Enterprise.
