In this study, we have been constructed measuring system for spill over by the Japan TV broadcasting signals and analyzed those signals using APD curve. In Busan, we have been measured channel of Japan TV broadcasting signals during 9 months. The quality of image is that maximum grade is 2.5 level, and the quality of sound is that maximum grade is 3 level. In the result of analysis for measured Japan TV broadcasting signals, we have been observed Japan TV broadcasting signals those we have been chosen the ch 36 and ch 38, plotted the APD curve of each channel for a season, in Specially.

In this paper, we have been developed the software in order to ostinato for spill over for TV broadcasting signals between Korea and Japan and analyzed those signals using APD curve. In Busan, we have been measured channel of Japan TV broadcasting signals during 9 months from February 2006 to October 2006. That system has been controled and translated the measured data to remote-control place. Finally it has computation and compared in the APD curve using ITU-R P.1546.

In this study, we have been constructed measuring system for interference for TV broadcasting signals between Korea and Japan. In Busan, we have been measured 14 channel of Japan TV broadcasting signals during 4 days. The quality of image is that 2.5 level is maximum grade, and the quality of sound is that 3 level is maximum grade. And we have been observed Japan TV broadcasting signals, in Busan, Ulsan, and Pohang. There are detected 40 channels. The 19, 24, 29, 36, 39 channels have 3.0 grade image quality and The maximum field strength is $71dB{\mu}V$/m.

Japan TV broadcasting signals are measured and analyzed to estimate spillover level from Japan during 44 months from Feb. 2003 to Oct. 2009. Electric field intensity spillover into Korea is measured using fixed measurement system in Busan, and the relationship between the measured data and the predicted value is analyzed by year and seasons. Measurement results show that spillover signals from Japan have a serious effect on Korea broadcasting environment, and so that proper digital switchover strategy is necessary to cope with the spillover situation.
