Verification and analysis for DTTB using the system to detect the state of reception : Practical Experiment in Fukuoka

Abstract

Even after the start of Digital Terrestrial Television Broadcasting (DTTB), we are required to continue broadcasting analog television. During this simulcast period, an unprecedented amount of TV channels will be used to cover both digital and analog broadcasting. It is predicted that this situation will bring us major difficulties in reception of DTTB due to disturbances caused by SFN and Co-channel interferences. It is currently very difficult to verify and analyze these interferences with the conventional method, so we have carried out a practical experiment in Fukuoka, Japan where the channels are very complex using our new system to detect the reception of DTTB in such a situation.
