Description
上述の例では、CPU24が工場出荷時にROM26に記憶されているEDIDを読み出し、HDMIレシーバ210に出力させることで、プレーヤ1にEDIDを通知する例を示したが、変形例1では、他の装置から受信したEDIDをプレーヤ1に通知する。
図8は、変形例2に係るレシーバおよびサーバの構成を示すブロック図である。図4と共通する構成については同一の符号を付し、説明を省略する。
図9は、変形例3に係る信号処理システムの構成を示す概略図である。図9に示す信号処理システムは、プレーヤ1、アダプタ2A、レシーバ200、複数のスピーカSP、ネットワーク11、およびサーバ(同図においては3つのサーバ10A、サーバ10B、およびサーバ10C)からなる。
