Claims (1)
つている信号と、スクランブルのかかつていない
信号とを再生している衛星放送受信機において、
脱着可能なデスクランブラの代わりに映像信号の
入力端子と出力端子間及び音声信号の入力端子と
出力端子間が短絡されたダミーアダプタを着装し
てスクランブルのかかつていない信号を受信可能
としたことを特徴とする衛星放送受信機。 In a satellite broadcast receiver equipped with a descrambler and reproducing scrambled signals and unscrambled signals,
Instead of a removable descrambler, a dummy adapter is installed in which the video signal input terminal and output terminal and the audio signal input terminal and output terminal are short-circuited, making it possible to receive scrambled signals that have never been seen before. Satellite receiver.
