24 hours a day, 365 days a year. Always watching over and delivering broadcasts.

In order to deliver programs from the broadcasting station to the viewers, we are responsible for tasks ranging from broadcast operation to transmission monitoring. We check the broadcast schedule of programs and commercials in advance, check the quality of audio and video data files, monitor the video and audio in real time during broadcasts while checking that the equipment is working properly so we are prepared to respond quickly when problems occur.

We also build lines to safely transmit videos created on-site, such as sports broadcasts. Since there are many different transmission methods, we consider various factors and think about the best solution.

The Line Center manages all signals that come into and out of the broadcasting station, both domestically and internationally. We also distribute video signals within the station. All video signals from terrestrial broadcasting to 4K broadcasting, come into Line Center, so we monitor them continuously to prevent broadcast accidents.
