Abstract

  　著作権保護を図りつつ互いに規格の異なる通信インターフェースにそれぞれ接続されたデジタルＡＶ機器同士の間でＡＶコンテンツの送受信を可能にするホームネットワークにおけるＡＶサーバ装置を提供する。コンテンツとその属性情報を記録するＨＤＤ１１、コンテンツのフォーマットを変換するフォーマット変換部１２、ＨＤＤ１１を介して外部機器とコンテンツの送受信を行うための複数の通信インターフェース１３，１４を有し、ＣＰＵ１６は、外部機器からコンテンツの再生出力要求があると、そのコンテンツの属性情報に含まれる記録元の通信インターフェースの規格情報および著作権保護情報、著作権保護の認証の有無、および再生出力先の通信インターフェースの規格情報に基づいて再生出力の可否を判断し、再生出力が可能なコンテンツを要求先の外部機器が受信可能なフォーマットにデータ変換して送出する。
