Among the many infrastructures damaged by the conflict in Ukraine, there is also the link network that enabled the connection between the regional TV offices and the central newsroom in Kyiv. The main antenna was on the capital’s broadcasting tower, which was damaged in March 2022. Since then, mobile crews who rely on the cellular network to send video footage have been handicapped due to the use of portable equipment which only allows for low-resolution transmission. To solve the problem, Japan thus donated a number of portable mini-repeaters to the public broadcasting company Nacional’na Suspil’na Teleradiokompanija Ukraïny.
Within six years, more than 90% of Japan’s commercial stations (44 out of 47) will leave medium-wave to switch to frequency modulation. In September 2028, only three stations will remain active in northern Japans Hokkaido and Akita Prefecture. But the airwaves will begin to empty from next year: the first channels will be turned off in the fall of 2023. The advertising crisis has prompted broadcasters to ask the communications ministry to migrate to FM to reduce operating costs: AM systems are energy-intensive, maintenance expenses are high, and antennas at least 100 meters high are needed to transmit. The last to leave the airwaves will be three Tokyo-based broadcasters-TBS Radio, Nippon Cultural Broadcasting and Nippon Broadcasting System-and some will continue to keep AM transmitters on after 2028. In Japan, the FM band goes from 76 to 95 MHz because the higher channels, before the digital switchover, were occupied by television. Written by Fabrizio Carnevalini
The Japanese public broadcaster reduces the offer of radio and TV channels. Three satellite TV channels (BS1, BS Premium and BS4K) will be merged into one channel, and consideration is being given to closing down BS8K. With regard to radio, two medium wave channel should become one. The operation will reduce expenses by 120 billion yen (1.34 billion dollars). The broadcaster has not stated the timing of the closures, but the operation could be part of the three-year plan starting in 2021. NHK in 2019 increased revenues by 10% and is criticized by commercial stations because it collects not only the tax on television sets, but in addition generates revenues from advertising.
