Three channels, which will cease to be used for analog satellite broadcasting in July 2011 and 4 channels of the BS-17 19, 21, and 23ch, which were assigned to Japan at the WRC-2000, will be used for new digital broadcasting services after 2011. In these channels, a new broadcasting system called "Advanced Digital Satellite Broadcasting System" will be available as well as the current ISDB-S one. The new system can increase transmission bit rate by 30%compared with the current ISDB-S system by using LDPC codes and a roll-off factor of 0.1. The Association of Radio Industries and Businesses (ARIB) conducted evaluation tests to acquire its C/N-BER and synchronous performance as well as confirm how well the TMCC signal functions. Demonstrative tests to transmit Super Hi-Vision were also performed. The tests were done using a satellite simulator and a real satellite transponder. The tests showed that the system performed very well, and the details are reported here.
