Claims (4)
- デジタル放送送信装置から送信したコンテンツを、デジタル放送受信装置(STB)で受信し、そのコンテンツをテレビ受信機や双方向リモコンの表示部に表示させることができるCATVシステムであって、前記デジタル放送送信装置は、放送番組のコンテンツに加えてリモコン専用コンテンツを含んで多重化して送信し、前記STBで、前記デジタル放送送信装置からの多重化されたコンテンツを分離手段で分離後、送信手段で前記分離された放送番組のコンテンツは前記テレビ受信機に送信されて前記放送番組が前記テレビ受信機の表示部に表示され、また前記リモコン専用コンテンツは前記双方向リモコンに送信されて前記リモコン専用コンテンツが前記双方向リモコンの表示部に表示されることを特徴とするCATVシステム。
- STBは、記憶手段を備え、分離手段で得られたリモコン専用コンテンツを記憶すると共に、前記記憶されたリモコン専用コンテンツがデジタル放送送信装置からの受信時に対して時差をもって読み出されて双方向リモコンに送信されることを特徴とする請求項1記載のCATVシステム。
- 双方向リモコンが、記憶手段を備え、受信するリモコン専用コンテンツを前記記憶手段に記憶し、その記憶した前記リモコン専用コンテンツを、受信後に時差をもって表示部に表示可能としたことを特徴とする請求項1記載のCATVシステム。
- STBを、複数のチューナ機能を備えたものとし、その内の1つを、デジタル放送送信装置からの多重化された信号の中でリモコン専用コンテンツを含む周波数を選択する設定としてある請求項1記載のCATVシステム。
