Abstract
Description
用途の異なる外部記録媒体の使い分けができる電子機器を提供する。」と記載があり、電子機器の外部記憶媒体の装填部に外部記憶媒体が装填されたときに、外部記憶媒体からISP情報やユーザのメールアカウント情報などのネットワーク接続機能を使用する際に必要な情報を読み出し、この読み出した情報を用いて、ネットワーク接続機能の送受のアクセスを実行するようにすることが記載されている。
また、プログレッシブダウンロードは、これら2つの中間に位置し、コンテンツのすべての配信が完了する前に、端末に蓄積された中から逐次視聴を行う。これにより、必ずしも蓄積完了を待つ必要が無く、帯域が十分広くない場合にも蓄積時間を短縮することができ、また、蓄積完了後であればユーザー所望のタイミングで何度も視聴できるというメリットを提供できる。
図1(a)は、第一の実施形態に係るネットワーク端末システムの一実施例を示すブロック構成図である。
また、無線ルーター5は、テレビ受信機1またはテレビ受信機2とは、有線LANまたは無線LANで接続されており、無線端末3または無線端末4とは無線LANで接続されているものとする。ここで、Wi-Fiは、IEEE(米国電気電子学会)の規格「IEEE 802.11a/IEEE 802.11b」で策定された無線LAN(Local Area Network)の標準規格である。
図1(b)は、テレビ受信機1の構成図の一例である。なお、テレビ受信機2の各部の構成は、テレビ受信機1と同様のため説明を省略する。テレビ受信機1は、例えば、アンテナ11に接続され、チューナ・復調部12、選局制御部13、信号分離部14、音声復調部15、スピーカ16、音声出力部17、映像復調部18、重畳部19、表示部20、映像出力部21、通信I/F22、入力手段23、制御部24、メモリ25、ストレージ26など有し、それぞれの処理部がバス28を介して接続される。
また、信号分離部14で所定の番組についてのトランスポートストリームを分離し、映像や音声を復号せずに出力するデジタルI/F27を設けてもよい。
図1(c)は無線端末3の構成図の一例である。なお、無線端末4の各部の構成は、無線端末3と同様のため説明を省略する。
図1(d)はコンテンツ配信サーバー7の構成図の一例である。コンテンツ配信サーバー7は、例えば、通信I/F50、制御部51、メモリ52、ストレージ53から構成され、それぞれの処理部がバス157を介して接続される。
図2(a)は、図1(b)における、テレビ受信機1またはテレビ受信機2の構成のうちメモリ25とストレージ26の構成を示す図である。図2(a)においてストレージ23は、ブラウザプログラム2001、接続機器認証プログラム2006、コンテンツ再生プログラム2007、各種アプリケーションプログラム2008、アカウント管理プログラム2009およびコンテンツ・アプリ同期処理プログラム2010を格納している。これらのプログラムは制御部24によりメモリ25に展開され、制御部24がプログラムを実行することでブラウザエンジン2101、接続機器認証部2106、コンテンツ再生部2107、各種アプリケーション部2108、アカウント管理部2109およびコンテンツ・アプリ同期処理部2110としての機能を実現する。ブラウザプログラム2001、接続機器認証プログラム2006、コンテンツ再生プログラム2007、各種アプリケーションプログラム2008、アカウント管理プログラム2009およびコンテンツ・アプリ同期処理プログラム2010は、製品の出荷時点でストレージ26に格納しておいてもよく、通信I/F22を介してダウンロードしてもよい。制御部24はこれらのプログラムを実行して各種機能を実現するが、以下の説明では、説明を簡単にするため、メモリ25内の各機能部が主体となって各種機能を実現するものとして説明する。
HTMLパーサー2102は、制御部24を介して取得したHTMLデータの論理的な構造を解析する。また、取得したHTMLデータを解釈し、テレビ受信機1で使用する内部データへ変換することができる。
データベース生成部2103は、そのHTMLデータ構造に関するデータベースを生成する。
レンダリング部2104は、データベースを基に各タグで決められた表現形式の情報を含むレイアウト構造を生成し、このレイアウト構造を基に、大きさ、位置、画像を取り込んだデータの通りにブラウザ表示画面を生成する。
画像処理部2105は、HTMLデータに画像タグで指定された画像ファイルの配置及び画像ファイル名などの画像ファイル情報に基づいて、取得した画像ファイルをビットマップ形式等の画像データに変換する。
テレビ受信機1のストレージ26の各種データに記憶される認証情報は、ユーザーによる入力手段23を用いた入力によって、若しくはテレビ受信機1の工場出荷前などに予め設定される。また、上記の認証情報はユーザによる操作によって表示部20に表示させたり、テレビ受信機1の購入時に添付された書類等によってユーザーが確認できるものとする。また、無線端末3または無線端末4のユーザー名とMACアドレスを、接続機器の認証情報として、テレビ受信機1のストレージ26や図示しない不揮発性メモリなどに格納してもよい。
また、無線端末の操作により、テレビ受信機側でコンテンツ配信サーバー7からコンテンツの配信を受け視聴する場合は、接続機器認証部2106は、各種データに記憶された認証情報を、通信I/F22、無線ルーター5を経由してコンテンツ配信サーバー7のユーザー管理部4101に対して送信する機能を持つ。また、このときはコンテンツ配信サーバー7に送信する機器認証情報は、無線端末3または無線端末4のユーザープロファイル生成部3109で生成されたユーザープロファイル情報のユーザー情報と関連付けされる。また、コンテンツ配信サーバー7が認識可能な情報として別々に管理することもできる。
また、コンテンツの再生停止位置の情報は、ストレージ26の各種データにレジューム情報として記憶することができ、同一ユーザーによる同一コンテンツの再生を再開する場合には、レジューム情報から再生停止した位置データを取得して再生開始位置とすることができる。レジューム情報は、無線端末から取得したユーザープロファイル情報を参照してユーザー毎に設定される。
また、アカウント管理部2109は、同時に複数のユーザーアカウントを受け付けることができ、またそれぞれを独立して管理することができる。各ユーザーアカウントに対して、同時動作が可能な場合は操作を許可し、同時動作が不可能で排他的な動作をしなければならない場合は、先に使用しているユーザーの無線端末に対して、そのユーザー情報を後からのユーザーの無線端末に対して送信し、テレビ受信機1の使用権の譲り受けや残りの使用時間等の問合せが可能となっている。
図2(b)は、図1(c)における、無線端末3または無線端末4の構成のうちメモリ33とストレージ34の構成を示す図である。図2(b)においてストレージ34は、ブラウザプログラム3001、機器認証プログラム3006、コンテンツ再生プログラム3007、各種アプリケーション部3008およびユーザープロファイル生成部3009を格納している。これらのプログラムは制御部37によりメモリ33に展開され、制御部37がプログラムを実行することでブラウザエンジン3101、接続機器認証部3106、コンテンツ再生部3107、各種アプリケーション部3108およびユーザープロファイル生成部3109として機能を実現する。ブラウザプログラム3001、機器認証プログラム3006、コンテンツ再生プログラム3007、各種アプリケーションプログラム3008およびユーザープロファイル生成プログラム3009は、製品の出荷時点でストレージ34に格納しておいてもよく、通信I/F39または移動体通信I/F40を介してダウンロードしてもよい。制御部37はこれらのプログラムを実行して各種機能を実現するが、以後の説明では、メモリ33内のプログラム機能部が主体となって実現するものとして説明する。
さらに、接続機器認証部3106は、各種データに記憶された認証情報をコンテンツの配信先の認証情報として、通信I/F39または移動体通信I/F40を経由して後述するコンテンツ配信サーバー7のユーザー管理部4101に対して送信する機能を持つ。また認証情報は、ユーザープロファイル生成部3109で生成されたユーザープロファイル情報のユーザー情報と関連付けされた、コンテンツ配信サーバー7が認識可能な情報としてユーザープロファイル情報とは別に管理することもできる。
また、コンテンツの再生停止位置の情報は、ストレージ34の各種データにレジューム情報として記憶することができ、同一コンテンツの再生を再開する場合にレジューム情報から再生停止した位置データを取得し再生開始位置とすることができる。レジューム情報は、ユーザープロファイル情報にも保存することができる。
図2(c)は、図1(d)における、コンテンツ配信サーバー7の構成のうちメモリ52とストレージ53の構成を示す図である。図2(b)においてストレージ53は、ユーザー管理プログラム4001、コンテンツ管理プログラム4002およびコンテンツ配信プログラム4003を格納している。これらのプログラムは制御部51によりメモリ52に展開され、制御部51がプログラムを実行することでユーザー管理部4101、コンテンツ管理部4102およびコンテンツ配信管理部4103としての機能を実現する。ユーザー管理プログラム4001、コンテンツ管理プログラム4002およびコンテンツ配信プログラム4003は、予め外部ストレージなどに格納することができる。制御部51はこれらのプログラムに従って各種機能を実現するが、以下の説明では、説明を簡単にするため、メモリ52内の各機能部が主体となってそれぞれの機能を実現するものとして説明する。
図3(a)、(b)は、それぞれ無線端末3または無線端末4のユーザープロファイル生成部3109で管理されるユーザープロファイル情報の内容例を示すデータテーブルである。ユーザープロファイル情報には、ユーザーID(管理番号)101、パスワード102、一意のユーザー名103、設定パラメータ104、アプリケーション種別105およびダウンロードコンテンツ106、機器種別情報107などが記憶されている。
設定パラメータ104は、メニュー等のユーザーが好みに応じて設定した情報を含む。
アプリケーション種別105は、購入時に実装されていたものやダウンロードにより購入等により入手したアプリケーションのタイトルを含む。
機器種別情報107は、携帯端末やタブレット等の種別、使用しているOS等のアプリケーションやコンテンツ再生時の互換性を表す情報であり、ユーザーエージェント(利用者があるプロトコルに基づいてデータを利用する際に用いるソフトウェアまたはハードウェア)を利用しても良い。本実施例では、ユーザーIDおよびパスワードによるユーザー認証を前提に説明するが、指静脈や指紋、音声、顔画像、虹彩等の一般的生体認証などであってもよく、その場合には適宜ユーザー認証情報の項目が変わる。
次に、本実施形態におけるシステムの動作について図5~図12を参照して説明する。テレビ受信機1は、テレビ受信機1に付属のリモコン等を使用し、1(TV):1(リモコン)の形態でテレビ受信機を単体で使用する場合と、一台または複数の無線端末を使用して、1(TV):1(無線端末)または1(TV):n(無線端末)の形態で使用する場合がある。本実施形態においては、テレビ受信機1と一台の無線端末3を接続した、1(TV):1(無線端末)の形態で使用する場合の実施例について述べる。また、複数の無線端末で1(TV):n(無線端末)の形態で使用する場合の実施例について、後述する第二の実施形態で述べる。また、テレビ受信機1を付属のリモコン等を使用し、1(TV):1(リモコン)の形態でテレビ受信機を単体で使用する場合の実施例について、後述する第三の実施形態で述べる。
図5において、無線端末3は操作端末として用いられ、コンテンツ配信サーバー7からテレビ受信機1にコンテンツを配信してテレビ受信機1にコンテンツを表示させる場合のテレビ受信機1とコンテンツ配信サーバー7との間でのコンテンツ情報のやりとりを開始するまでの動作を示す。
図6は、無線端末3のメニュー画面の表示例を示す。また、図7は、無線端末3の接続機器一覧表示画面の表示例を示す。
もし、認証情報が一致しない場合は(S104:NO)、無線端末3のユーザーに対してエラーメッセージを送信する。認証情報が一致しない場合は、再入力を促すようなメッセージを表示してもよい。また、既に認証済みのユーザーが存在する場合は(S105:YES)、メッセージを送信し、先に認証済みの無線端末を優先し、無線端末3の使用を中止することができる。
図11において、コンテンツタイトル表示219には、コンテンツタイトル名、視聴料金、視聴期間等が表示される。また、「戻る」ボタン221は、タップ操作により上の階層に戻るためのボタンであり、一つ前のジャンル階層に戻ることができる。図11の例では、映画のジャンルの内の「邦画」222を選択していることを示している。「終了」ボタン223は、タップ操作によりコンテンツ視聴を中止することを指示するための操作部である。
また、第一の実施形態と比較し、異なるところを強調して説明する。システム構成、テレビ受信機1のソフトウェア構成、無線端末3のソフトウェア構成については、第一の実施形態と同様のため説明は省略する。
図13は、第二の実施形態に係る動作シーケンスの一例を示す図である。本実施形態においては、1台のテレビ受信機を複数の無線端末で、1(TV):n(無線端末)形態で使用する場合の実施例について述べる。図13は、第一の実施形態の図5に対応する動作を示すシーケンス図であり、無線端末3がテレビ受信機1から認証を受け、テレビ受信機1が無線端末3からプロファイル情報を取得する場合の一実施例を示す。第一の実施形態の図5に対して、制限モードの処理(ステップS301~ステップS303)が追加になっている。
以下、ステップS106~ステップS109までは、第一の実施形態の図5と同じため、説明を省略する。
なお、本実施形態では、無線端末を使用しないでテレビ受信機1をリモコン等で使用する場合の実施例である。また、第二の実施形態と比較し、異なるところを強調して説明する。システム構成、テレビ受信機1のソフトウェア構成については、第一の実施形態と同様のため説明は省略する。
図16は、第三の実施形態に係る動作シーケンスの一例を示す図である。本実施形態においては、テレビ受信機1を付属のリモコン等を使用し、1(TV):1(リモコン)の形態で使用する場合の実施例について述べる。無線端末を使用しないでテレビ受信機1を使用する場合は機器認証操作が不要である。
また、第一、第二または第三の実施形態と比較し、異なるところを強調して説明する。システム構成、テレビ受信機1のソフトウェア構成、無線端末3のソフトウェア構成については、第一の実施形態と同様のため説明は省略する。
図20は、本実施形態に係る動作シーケンスの一例を示す図である。本実施形態では、第一の実施形態の図5で、ステップS109で保存したプロファイル情報が、テレビ受信機1の操作の途中で変更になった場合に更新されたプロファイル情報を無線端末側に保存するようにしたものである。図20では、新たにS601~S605が追加されている。
また、第三の実施形態と比較し、異なるところを強調して説明する。システム構成、テレビ受信機1のソフトウェア構成、無線端末3のソフトウェア構成については、第一の実施形態と同様のため説明は省略する。
図21は、本実施形態に係る動作シーケンスの一例を示す図である。本実施形態では、第三の実施形態でテレビ受信機1を単体で使用する場合に、先行して無線端末3のプロファイル情報をテレビ受信機1にエクスポートしておいて、無線端末3と同様の使用環境でテレビ受信機1を単体で使用する場合の一実施例を示す。図21は、第三の実施形態の図16または図17の動作フローの開始の前に、新たにステップS701~ステップS707を追加したものである。
また、第二の実施形態と比較し、異なるところを強調して説明する。システム構成、テレビ受信機1のソフトウェア構成、無線端末3のソフトウェア構成については、第一の実施形態と同様のため説明は省略する。
図22は、本実施形態に係る動作シーケンスの一例を示す図ある。本実施形態では、第二の実施形態の図15で、すでに認証済みのユーザー(無線端末4)が存在し、コンテンツ配信サービス等で操作または動作を行っているときに、他のユーザーが制限モードで動作を行っており、テレビ受信機1が2画面などのマルチ画面により、複数のチャンネルの番組を同時表示ができるような場合の一実施例について述べる。第二の実施形態の図15に対して、新たにステップS801~S803を追加したものである。
