Abstract

　コンテンツ配信システムにおいて、コンテンツのダウンロードに要する時間を短縮するとともに、ユーザ端末の記憶装置の容量を有効に使用することができる。クライアント端末４は、配信すべきコンテンツを指定するとともにそのコンテンツの中でダウンロードすべき情報を配信サーバ２に要求する。配信サーバ２は、クライアント端末４により指定されたコンテンツから要求された情報を抽出してダウンロードする。コンテンツには、主情報であるメインコンテンツとこれに関連する副情報であるサブコンテンツが含まれる。例えばクライアント端末４は、ダウンロードすべき情報としてコンテンツからＣＭを削除して番組本編のみを選択することができる。
