Digital terrestrial television broadcasting has brought strikingly higher quality and functionality to television broadcasting, and it has also promoted the effective use of radio frequencies as a public resource.
In Japan, the reorganization of frequencies in the move from analogue to digital broadcasting led to the 370-MHz frequency bandwidth for the 62 channels that had been used for analogue broadcasting being cut to a 240-MHz bandwidth for 40 digital channels.
The remaining bandwidth of 130 MHz, equivalent of 22 channels, was allocated to multimedia broadcasting, next-generation cell phone services and other new radio systems.
NHK has been doing R & D on next-generation terrestrial digital broadcasting to achieve even higher efﬁciency.
In this broadcast white paper, we explain large-capacity transmission technology for the next generation of terrestrial digital broadcasting and highly efﬁcient transmission technology for mobile and cellular terminals.
