- マスタ装置(AV1)とスレーブ装置(AV2、PC、LSij、DSij)間のバス型ネットワーク上で、セキュア通信のための双方向データストリーム(DSA)と、リアルタイム通信のための一方向データストリーム(DSI)を用いて通信を行う方法において、
一方向データストリーム(DSI)は、マスタ装置(AV1)と少なくとも1つのスレーブ装置(AV2、PC、LSij、DSij)間での、ある種のセキュア通信(CIV、CIB)のために使用されることを特徴とする方法。 - 前記ある種のセキュア通信(CIV、CIB)は、制御コマンド(CIV、CIB)であることを特徴とする請求項1に記載の方法。
- 前記ある種のセキュア通信(CIV、CIB)は、繰り返し送信されることを特徴とする請求項1又は2に記載の方法。
- 通信ネットワークの妨害を検出し、その程度を判定し、妨害の程度に基づき、セキュア通信のための一方向データストリームの使用を減らすことを特徴とする請求項1から3のいずれか1項に記載の方法。
- スレーブ装置(AV2、PC、LSij、DSij)により、他の幾つかの装置(AV2、PC、LSij、DSij)に宛てて発行されるセキュア通信のための情報は、セキュア通信のための情報として、マスタ装置(AV1)のみに宛てて発行され、
マスタ装置が、該セキュア通信のための情報を、前記ある種のセキュア通信のための情報(CIV、CIB)として、一方向データストリーム(DSI)により他の装置(AV2、PC、LSij、DSij)に送信することを特徴とする請求項1から4のいずれか1項に記載の方法。 - 請求項1からの5のいずれか1項に記載の通信を実行するスレーブ装置での方法において、
スレーブ装置(AV2、PC、LSij、DSij)は、前記ある種のセキュア通信のための情報(CIV、CIB)を取り出すために、
バスから受信する双方向データストリーム(DSA)と一方向データストリーム(DSI)の両方を読み出して復号することを特徴とする方法。 - 請求項1からの5のいずれか1項に記載の通信を実行するマスタ装置での方法において、
マスタ装置(AV1)は、ある種のセキュア情報(CIV、CIB)を、一方向データストリーム(DSI)を使用して、バス上の幾つかのスレーブ装置(AV2、PC、LSij、DSij)に送信することを特徴とする方法。 - 請求項1から5のいずれか1項に記載の方法を実行するネットワーク、請求項1から6のいずれか1項に記載の方法を実行するスレーブ装置又は、請求項1から5と7のいずれか1項に記載の方法を実行するマスタ装置。
