Development of the system to detect the state of reception for Digital Terrestrial Television Broadcasting

Abstract

The transition from analog to digital broadcasting will be performed in a stepwise manner, and there will be a simulcast period until that migration is complete. This will result in more transmitter sites and even more complicated frequency planning. There is a high probability that interference and other disturbances will occur. The system that we have developed can automatically detect the state of reception for each channel or the mutual state of reception between channels. The system is an important measurement equipment for the DTTB.
