Claims (1)
おいて、複合映像信号から得られた一方の方式の同期信
号周波数と、他方の方式で動作している水平回路から得
られた出力信号の周波数の違いを検知して、水平回路の
発振周波数を自動的に同期信号と同じ方式の周波数に切
換える装置を有する水平発振回路。In a television that operates with two broadcasting systems (horizontal oscillation frequencies), the synchronization signal frequency of one system obtained from the composite video signal and the frequency of the output signal obtained from the horizontal circuit operating with the other system. A horizontal oscillation circuit that has a device that detects the difference and automatically switches the oscillation frequency of the horizontal circuit to the same frequency as the synchronization signal.
