- the setting information 2100 has substantially the same configuration as the setting information 300, but unlike the setting information 300, a viewing restriction level 2109 is set.
- the viewing restriction level 2109 is a numerical expression of the severity of viewing restrictions in the type of content, and the higher the numerical value, the more severe the viewing restrictions are set. When the high level viewing restriction is released, the lower level viewing restriction is also released.
- “at the start of playback” of the viewing restriction release timing 2103 means that the timing for displaying the GUI for requesting the release of restriction is when executing the playback of the content of that type, and “when selecting a menu item”. This means that the timing for displaying the GUI requesting the restriction release is when the menu for releasing the viewing restriction is selected.
- “display program name & include in all programs” of the display method 2106 before viewing restriction release means displaying the program name and displaying the program name in all program tabs.
- the display method 2106 before the viewing restriction is canceled “Hide program name & not include in all programs” means that the program name is not displayed and the program name is not displayed in all program tabs. .
- FIG. 22 is a flowchart showing the operation of the content reproduction device 300 according to the third embodiment.
- the operation of the viewing restriction state management unit 104 is different from that shown in the first embodiment.

(条件3)クライアント側の時間情報つまり使用している時間に応じてサーバ側(コンテンツ再生装置500側)とクライアント側(携帯電話機170側)のうちいずれに記憶されている年齢情報を用いるかを切り替える。例えば、夜間(22時~6時)はクライアント側(携帯電話機170側)の年齢情報を用い、それ以外の時間帯ではサーバ側(コンテンツ再生装置500側の年齢情報を用いる。
<補足>
上記実施形態において、本発明の実施の手法について説明してきたが、本発明の実施形態がこれに限られないことは勿論である。以下、上記実施形態以外に本発明の思想として含まれる各種の変形例について説明する。
(1)上記実施の形態においては、コンテンツ再生装置100をユーザが操作するための入力を、リモコン160や、携帯電話機170を介して受け付けていたが、当該入力は、コンテンツ再生装置100に直接付設されているコントロールパネルを介して受け付けてもよい。
(2)上記実施の形態における各記憶部(設定情報記憶部109、表示プログラム記憶部110、コンテンツ記憶部111、プログラムテンプレート記憶部112)は、それぞれ別個のデータを記憶するメモリあるいはHDDであってもよいし、各記憶部が記憶すべきデータを記憶するための領域を、1のメモリあるいは1のHDDの記憶領域内にそれぞれ別個に設定する構成であってもよい。
(3)上記実施の形態においては例えば、図9に示したように、GUIにおいて各制限情報が付加されたコンテンツを容易に区別するべくタブ形式で各制限情報のコンテンツ一覧を表示することとしたが、これはタブ形式に限定しなくともよく、各制限情報が付加されたコンテンツをユーザが容易に認識できるものであればよい。例えば図37に示すように、2ペイン形式で表示することとしてもよいし、あるいは図38に示すように、ツリー構造形式で表示することとしてもよい。
(4)上記実施の形態における設定情報300に示した制御例は、一例であり、図3や、図20に示したもの以外の制御方法を設定し、コンテンツ再生装置100はその制御方法に基づく制御を行ってもよい。例えば、視聴制限解除後の表示方法について、「制限なし表示にも含める」場合と、「制限なし表示には含めない」場合とを示したが、例えば、「R-15指定」や「R-20指定」のコンテンツを「年齢制限あり」という一覧を生成して、当該一覧に含める制御を実行できるように設定情報300を設定してもよい。
(5)上記実施の形態においては、暗証番号は、各制限情報の種別ごとに設定したが、これは各コンテンツそれぞれで異なる暗証番号を用いてもよく、この場合、認証情報510は、各コンテンツ管理IDに暗証番号を対応付けた情報となる。
(6)上記実施の形態においては、取得したコンテンツに設定情報データが付随していることとした。しかし、コンテンツに設定情報データが付随していないことも考えられる。
(7)上記実施の形態においては、選択されているコンテンツ一覧のみを表示することとしたが、画面のサイズが許すならば、全部、あるいは複数のコンテンツ一覧を表示してもよい。
(8)上記実施の形態4において、各サービス毎の設定情報を別々に保持する場合を説明した。しかし、これは別々に保持せずに一つのリストにする構成をとってもよい。つまり、その場合には、設定情報は、更に一つサービスを特定するための情報が対応付けられる(図3を用いて説明するならば、更にサービスを特定するための欄が設けられる)ことになり、設定情報の更新に当たっては、サービスサーバから取得した設定情報を用いて、元々記憶している設定情報のうち、取得した設定情報に対応するサービスに対応する部分のみを更新することになる。
(9)上記実施の形態5においては、コンテンツ再生装置100が管理するWebページにアクセスしてコンテンツ再生装置100を操作できる機器として携帯電話機を例に示したが、これは携帯電話機のみに限らず、インターネットにアクセスできる通信機能を保持する機器であればよく、例えば、ネット通信機能を有するデジタルテレビ、デジタルカメラ、デジタルビデオカメラ、カーナビゲーションシステム、ポータブルBD/DVDプレーヤ、PDA(Personal Digital Assistants)などであってもよい。
(10)上記実施の形態5においては、携帯電話機170は、HTTPを使ってコマンド送受信することで、コンテンツ再生装置500を操作することとしたが、携帯電話機170が赤外線通信を実行する機能があるならば、当該機能を用いて、コンテンツ再生装置100を操作することとしてもよい。
(11)上記実施の形態においては、表示プログラム生成部107により、コンテンツ再生装置100の電源が入れられる都度、動的にGUIプログラムを作成することを示した。しかし、コンテンツ再生装置100に表示プログラム生成部107とプログラムテンプレート記憶部112を搭載せず、予め表示プログラム記憶部110に、予めどのような視聴制限が付加されたコンテンツを取得したとしても対応できるように作りこまれたGUIプログラムが記憶されていてもよい。即ち、表示プログラム記憶部110は、全ての視聴制限に関するタブが用意されており、GUIを表示する際には、単純に各コンテンツの識別情報、即ちタイトルを振り分けるだけですむようなGUIプログラムを記憶しておく。
(12)上記実施の形態においては、リモコン160からのパスワードの入力に応じて視聴制限を解除する場合や、外部機器からのパスワードの入力に応じて視聴制限を解除する場合を示したが、同時に複数の機器(リモコン160と携帯電話機170など)からの操作を受け付けることも考えられる。そのため、視聴制限状態管理部104は、各機器に対応して、それぞれの制限解除状態を管理することとしてもよい。
(13)上記実施の形態5では、サーバ側(コンテンツ再生装置500側)、クライアント側(携帯端末170側)のいずれの年齢情報を用いるかの判断を、サーバ側(コンテンツ再生装置500側)で実行することとした。
(14)上記実施の形態における各機能部は、1または複数のLSI(Large Scale Integration)によって実現されてもよく、1のLSIが複数の機能部が有する機能を実行できるように実現されてもよい。LSIは、集積度の違いにより、VLSI(Very Large Scale Integration)、ウルトラLSIなどと呼称されることもある。
(15)上述の実施形態で示したGUIの表示に係る動作、GUIの生成処理等(図17参照)をコンテンツ再生装置のプロセッサ、及びそのプロセッサに接続された各種回路に実行させるためのプログラムコードからなる制御プログラムを、記録媒体に記録すること、または各種通信路等を介して流通させ頒布させることもできる。このような記録媒体には、ICカード、ハードディスク、光ディスク、フレキシブルディスク、ROM等がある。流通、頒布された制御プログラムはプロセッサに読み出され得るメモリ等に格納されることにより利用に供され、そのプロセッサがその制御プログラムを実行することにより、実施形態で示したような各種機能が実現されるようになる。
