Abstract
【解決手段】 コンピュータ生成画像をも表示し得る、標準精細度または高精細度の放送信号源からの画像を表示を行うために、水平周波数信号発生器300は複数の周波数で選択的に動作可能であり、複数の水平周波数で同期発振するように制御される発振器を具えている。同期パルス5の信号源SW15は位相検出器50の入力に結合され、位相検出器50の別の入力は発振器300/400に結合される。位相検出器50は2入力間の位相差を表す出力信号11を発生する。プロセッサ200が、位相検出器50に結合されており、出力信号11を処理し、発振器300/400を制御するための制御信号を発生する。プロセッサ200のゲインは複数の周波数の中の選択されたものに応じて制御される。
