Description
本出願は、2010年5月4日出願の米国特許仮出願第61/330,993号及び第61/331,092号の両方からの優先権を請求するものである。
特許文献1等に開示されているように、映像等のメディアで構成する番組情報のようなコンテンツをインターネットプロトコルで配信する放送サービス(IPTVサービス)について、ネットワークを用いたコンテンツ配信方法が開発されてきている。引用文献1では、コンテンツ配信サービスにおいて認証を行う端末とコンテンツの配信等を行う端末とを分けることにより視聴可能とする技術を提供しており、例えば、携帯端末で認証を実行し、比較的大画面を有するTV端末で視聴等を行うことがでるようになっている。
TVを通じたインターネットアクセスは、一般的に、まるでTVがブラウザを実行するコンピュータであるかのようにTVを実質的にプログラムすることによって提供される。従って、このようなインターネットアクセスは、ファイアウォール又はフィルタリングプログラムがいくつかのサイトを遮断することができるような場合を除いて制御されない。
