Abstract
コンテンツ配信システム(1)は、一又は複数のコンテンツを管理するコンテンツ管理手段(40)と、コンテンツのマルチキャストストリームを配信するマルチキャスト配信手段(20)と、コンテンツのユニキャストストリームを配信するユニキャスト配信手段(30)と、端末(60)とを備える。コンテンツ管理手段は配信の要求に応じて、端末にマルチキャスト配信手段を特定する第1情報及びユニキャスト配信手段を特定する第2情報を送信し、端末は第1情報に基づいて、所望コンテンツに対応するマルチキャストストリームを受信して再生し、端末は特殊再生の要求が受け付けられた際に、第2情報に基づいてユニキャスト配信手段に特殊再生を要求し、ユニキャスト配信手段は特殊再生の要求に応じて、端末に特殊再生のためのユニキャストストリームを配信し、端末は特殊再生のためのユニキャストストリームを受信して再生する。
