Description

放送受信装置、情報端末および放送受信方法Broadcast receiving apparatus, information terminal, and broadcast receiving method
　本発明は、放送受信装置，情報端末および放送受信方法に関する。 The present invention relates to a broadcast receiving apparatus, an information terminal, and a broadcast receiving method.
　ラジオ放送やテレビ放送において、それらの放送信号に文字コードや図形情報、放送される番組に関連する情報を重畳する文字多重放送技術が知られている。たとえば、ＦＭ文字多重放送技術（Ｄａｔａ　Ｒａｄｉｏ　Ｃｈａｎｎｅｌ方式）のようなラジオ放送では、割り当てられたチャンネル内の空き周波数、ステレオ放送に用いる副搬送波の高域にそれらの情報を重畳することにより行なわれる。また、テレビ放送では垂直同期と有効映像範囲の間に残されている余白の走査線にそれらの情報を重畳することにより行なわれる。 In radio broadcasts and television broadcasts, there is known a text multiplex broadcast technique in which character codes, graphic information, and information related to broadcast programs are superimposed on those broadcast signals. For example, in radio broadcasting such as the FM character multiplex broadcasting technology (Data Radio Channel system), the information is superimposed on the vacant frequency in the assigned channel and the high frequency of the subcarrier used for stereo broadcasting. In television broadcasting, the information is superimposed on the scanning line of the blank space remaining between the vertical synchronization and the effective video range.
　ところで、特許文献１には、ユーザがＵＲＬ情報などのアドレス情報を入力する操作をしなくとも、多くの有用な情報が得られる文字放送受信機能が内蔵された携帯電話機が開示されている。この携帯電話機では、送信する文字データなどをＨＴＭＬ形式の所定のタグなどを使用することで、ユーザ自らがＵＲＬ情報などのアドレス情報を入力する手間を省いている。 By the way, Patent Document 1 discloses a mobile phone with a built-in teletext receiving function that can obtain a lot of useful information without the user having to input address information such as URL information. In this cellular phone, the user does not have to input address information such as URL information by using a predetermined tag in the HTML format for character data to be transmitted.
特開２００４－１１２６７３号公報（要約など）JP 2004-112673 A (summary etc.)
　上述した文字多重放送技術は、テレビ放送においては補完的なサービスとして放送局やその関連会社が制作し、放送されている。たとえば、株式市況やニュース・天気予報などを簡易な画像データや文字データとして放送する内容と共に提供している。しかしながら、文字多重放送技術で送信できる情報量は、インターネットや近年広がりつつある地上波デジタル放送などと比較すると少ない。しかも、上述した文字多重放送技術では、インターネットや地上波デジタル放送のようにリアルタイム且つオンデマンドで様々な情報を提供することが困難である。 The above-mentioned teletext broadcasting technology is produced and broadcast by broadcasting stations and their affiliates as a complementary service in television broadcasting. For example, stock market conditions, news / weather forecasts, etc. are provided along with simple image data and text data. However, the amount of information that can be transmitted by the text multiplex broadcasting technology is small compared to the Internet and terrestrial digital broadcasting that has been spreading in recent years. Moreover, it is difficult to provide various information in real time and on demand, such as the Internet and terrestrial digital broadcasting, with the above-described text multiplex broadcasting technology.
　特許文献１に開示される携帯電話機では、上述した文字多重放送技術のように送信できる情報量が少ない点に関してはインターネットなどを利用することで解消できる。しかしながら、特許文献１に開示される携帯電話機であっても、送信する情報を、文字放送用の領域にＨＴＭＬ形式で予め所定のタグ（たとえばＡタグなど）によりＵＲＬ情報のアドレス情報を必ず記述しておかなければならない。したがって、情報を送信する側では、必ず所定のタグを用いて記述しなければならない。また、特許文献１に開示される携帯電話機では、ユーザの所定の操作（たとえば当該ＵＲＬ情報へ接続するボタンをクリックするなど）が必ず行なわなければ、当該ＵＲＬ情報などのアドレス情報の示すサイトへ接続することができない。そのため、たとえばこの技術を放送受信装置に適用した場合、放送局から配信する放送データにＨＴＭＬ形式で予め所定のタグにより記述したＵＲＬ情報などのアドレス情報を重畳して配信する必要が生じる。また、ユーザは、視聴したいチャンネルを設定する選局操作とは別に放送局のホームページなどの関連サイトに接続するための所定の操作を毎回行なう必要が生じる。 In the cellular phone disclosed in Patent Document 1, the small amount of information that can be transmitted as in the above-described text multiplex broadcasting technique can be solved by using the Internet or the like. However, even in the cellular phone disclosed in Patent Document 1, the address information of the URL information must be described in advance in a predetermined tag (for example, A tag) in the HTML format in the area for character broadcasting. I have to keep it. Therefore, the information transmitting side must be described using a predetermined tag. In addition, in the mobile phone disclosed in Patent Document 1, if a user's predetermined operation (for example, clicking a button for connecting to the URL information) is not necessarily performed, the mobile phone is connected to the site indicated by the address information such as the URL information. Can not do it. Therefore, for example, when this technology is applied to a broadcast receiving device, it is necessary to superimpose and distribute address information such as URL information previously described in a predetermined tag in HTML format on broadcast data distributed from a broadcast station. In addition to the channel selection operation for setting a channel to be viewed, the user needs to perform a predetermined operation for connecting to a related site such as a homepage of a broadcasting station every time.
　そこで、本発明は、上述した課題を鑑み、ユーザが選局操作に加えて所定の操作を毎回行なわなくとも放送データに関連するコンテンツを容易に取得できる放送受信装置、情報端末、放送受信方法を提供することを目的とする。 Therefore, in view of the above-described problems, the present invention provides a broadcast receiving apparatus, an information terminal, and a broadcast receiving method that allow a user to easily acquire content related to broadcast data without performing a predetermined operation every time in addition to a channel selection operation.

　ステップＳ９：制御部１５は、ＨＰの表示が許可されているか否かを判定する。具体的には、記憶部１３に格納されている基本ＵＲＬ情報の示すサイトの表示許可判定フラグを参照して判定を行なう。なお、このフラグは入力部１４でユーザの操作により設定してもよいし、放送受信装置１０の製品出荷時に対応テーブルＴ１に記憶させておいてもよい。また、ＨＰの表示が不許可と判定される例としては、対応テーブルＴ１の放送局２の基本ＵＲＬ情報に記録がない、ユーザの操作により入力部１４でＨＰの表示が不要と設定された場合などがある。制御部１５は、ＨＰの表示が許可されていると判定したとき（ステップＳ９でＹＥＳ）は、ステップＳ１１の処理へ移行する。一方、制御部１５は、ＨＰの表示が許可されていないと判定したとき（ステップＳ９でＮＯ）は、ステップＳ１２の処理へ移行する。 Step S9: The control unit 15 determines whether or not HP display is permitted. Specifically, the determination is performed with reference to the display permission determination flag of the site indicated by the basic URL information stored in the storage unit 13. This flag may be set by a user operation at the input unit 14 or may be stored in the correspondence table T1 when the broadcast receiving apparatus 10 is shipped. Further, as an example in which it is determined that the HP display is not permitted, there is no record in the basic URL information of the broadcasting station 2 in the correspondence table T1, and it is set that the HP display is not required by the input unit 14 by the user's operation and so on. When it is determined that the HP display is permitted (YES in step S9), the control unit 15 proceeds to the process of step S11. On the other hand, when determining that the display of HP is not permitted (NO in step S9), the control unit 15 proceeds to the process of step S12.
　ステップＳ１０：制御部１５は、当該放送局２のＨＰを表示部１６に表示して、ステップＳ１３の処理へ移行する。 Step S10: The control unit 15 displays the HP of the broadcasting station 2 on the display unit 16, and proceeds to the process of step S13.
　ステップＳ１１：制御部１５は、放送データの映像／画像情報で表示される画面と基本ＵＲＬ情報に基づいて表示される画面をそれぞれ表示部１６に表示し、ステップＳ１３の処理へ移行する。 Step S11: The control unit 15 displays on the display unit 16 the screen displayed based on the video / image information of the broadcast data and the screen displayed based on the basic URL information, and proceeds to the process of step S13.
　ステップＳ１２：制御部１５は、放送データの中の映像／画像情報のみを表示部１６に表示し、ステップＳ１３の処理を移行する。 Step S12: The control unit 15 displays only the video / image information in the broadcast data on the display unit 16, and proceeds to the process of step S13.
　ステップＳ１３：制御部１５は、図３で示した選局受付処理（図３のステップＳ１）へと処理を移行する。 Step S13: The control unit 15 shifts the process to the channel selection reception process (step S1 in FIG. 3) shown in FIG.
　このような放送受信装置１０の放送受信方法は、制御部１５の制御により、ユーザの選局操作に応じて、選局受付処理および表示処理を行なうため、選局された放送局２に関連するＵＲＬ情報の示すサイトへ自動的に接続し、表示部１６に表示させることができる。したがって、ユーザが選局操作に加えて所定の操作を毎回行なわなくとも放送データに関連するコンテンツ（放送局のＨＰなど）を容易に取得することができる。また、このような放送受信方法によれば、ユーザから表示可否選択を入力部１４で受け付け、表示許可判定フラグを用いることで、放送局２側が映像／画像情報を配信している場合に、選局された放送局２に関連するＵＲＬ情報の示すサイトの表示可否の設定を行なうこともできる。 Such a broadcast receiving method of the broadcast receiving apparatus 10 is related to the selected broadcast station 2 in order to perform the channel selection reception process and the display process in accordance with the user channel selection operation under the control of the control unit 15. It is possible to automatically connect to the site indicated by the URL information and display it on the display unit 16. Therefore, content related to broadcast data (such as HP of a broadcast station) can be easily obtained without the user performing a predetermined operation every time in addition to the channel selection operation. In addition, according to such a broadcast receiving method, the selection of whether or not to display can be received from the user by the input unit 14 and the display permission determination flag is used, so that the selection can be made when the broadcast station 2 side distributes video / image information. It is possible to set whether or not to display a site indicated by URL information related to the broadcast station 2 that has been stationed.
　続いて、図４で示した表示処理が行なわれ、放送受信装置１０の表示部１６に表示される画面例について説明する。図５は、図４に示すステップＳ８、Ｓ９、Ｓ１１、Ｓ１３の順で表示処理が行なわれた場合の放送受信装置１０の表示部１６に表示される画面例である。 Subsequently, an example of a screen displayed on the display unit 16 of the broadcast receiving apparatus 10 after the display process shown in FIG. 4 is performed will be described. FIG. 5 is a screen example displayed on the display unit 16 of the broadcast receiving apparatus 10 when the display process is performed in the order of steps S8, S9, S11, and S13 shown in FIG.
　図５に示すように、ユーザが選局操作をすると、表示部１６の画面の表示領域Ｗ１には放送データに含まれる映像／画像情報が表示されると共に、表示領域Ｗ２には放送局２に関連するＵＲＬ情報の示すサイトが２画面で表示されることとなる。 As shown in FIG. 5, when the user performs a channel selection operation, video / image information included in the broadcast data is displayed in the display area W1 of the screen of the display unit 16, and the broadcast area 2 is displayed in the display area W2. The site indicated by the related URL information is displayed on two screens.
（第２実施形態に係る放送受信装置２０）
　続いて、本発明の第２実施形態に係る放送受信装置２０について説明する。本発明の第２実施形態に係る放送受信装置２０は、第１実施形態に係る放送受信装置１０と異なり、表示するサイトページが時間帯に応じて変化するものである。また、この放送受信装置２０は、図６～図８に示す対応関係を有する対応テーブルＴ２を記憶部１３に有している。なお、第２実施形態に係る放送受信装置２０は、対応テーブルＴ１に加えて対応テーブルＴ２を有している以外は、図１に示す放送受信システム１と構成および動作が同一であるため、図示および各構成の機能および動作についての説明は省略する。以下に、第２実施形態に係る放送受信装置２０の記憶部１３に記録されている対応テーブルＴ２について図６～図８を参照しながら説明する。 (Broadcast receiving device 20 according to the second embodiment)
Next, the broadcast receiving device 20 according to the second embodiment of the present invention will be described. Unlike the broadcast receiving apparatus 10 according to the first embodiment, the broadcast receiving apparatus 20 according to the second embodiment of the present invention changes the displayed site page according to the time zone. Further, the broadcast receiving apparatus 20 has a correspondence table T2 having the correspondence shown in FIGS. The broadcast receiving apparatus 20 according to the second embodiment has the same configuration and operation as the broadcast receiving system 1 shown in FIG. 1 except that it includes the correspondence table T2 in addition to the correspondence table T1. Description of the function and operation of each component is omitted. The correspondence table T2 recorded in the storage unit 13 of the broadcast receiving apparatus 20 according to the second embodiment will be described below with reference to FIGS.
　図６は、本発明の第２実施形態に係る放送受信装置２０の記憶部１３に記録されている対応テーブルＴ２の一部の対応関係Ｔ２Ａを示す図である。図７は、本発明の第２実施形態に係る放送受信装置２０の記憶部１３に記録されている対応テーブルＴ２の一部であって、図６で示す対応関係Ｔ２Ａとは異なる対応関係Ｔ２Ｂを示す図である。図８は、本発明の第２実施形態に係る放送受信装置２０の記憶部１３に記録されている対応テーブルＴ２の一部であって、図６および図７で示す対応関係Ｔ２Ａ、Ｔ２Ｂとは異なる対応関係Ｔ２Ｃを示す図である。なお、図６～図８に示す対応関係Ｔ２Ａ、Ｔ２Ｂ、Ｔ２Ｃは、便宜上、放送局「ＦＭ日本」に関する情報のみを示しているが、対応テーブルＴ２には他の放送局２についても時間帯に応じて同様の情報が複数格納されているものとする。 FIG. 6 is a diagram showing a partial correspondence T2A of the correspondence table T2 recorded in the storage unit 13 of the broadcast receiving apparatus 20 according to the second embodiment of the present invention. FIG. 7 is a part of the correspondence table T2 recorded in the storage unit 13 of the broadcast receiving apparatus 20 according to the second embodiment of the present invention. The correspondence relationship T2B is different from the correspondence relationship T2A shown in FIG. FIG. FIG. 8 is a part of the correspondence table T2 recorded in the storage unit 13 of the broadcast receiving apparatus 20 according to the second embodiment of the present invention. The correspondence relationships T2A and T2B shown in FIGS. It is a figure which shows different corresponding relationship T2C. The correspondence relationships T2A, T2B, and T2C shown in FIGS. 6 to 8 show only information related to the broadcast station “FM Japan” for convenience, but the correspondence table T2 also shows other broadcast stations 2 in the time zone. Accordingly, it is assumed that a plurality of similar information is stored.
　図６で示す対応関係Ｔ２Ａに示すように、対応テーブルＴ２には、図２で示した「ＦＭ日本」という放送局２に関連付けられた番組ＵＲＬ情報が時間帯によりそれぞれ記録されており、これらの複数の番組ＵＲＬ情報に基づいて時間帯に応じた接続先の変更を可能としている。たとえば、２００８年７月１０日０：１０に「ＦＭ日本」を選局すると、放送受信装置１０の制御部１５は、この対応テーブルＴ２を参照し、番組ＵＲＬ情報が「ｈｔｔｐ：／／ｗｗｗ．ｆｍ＿ｎｉｐｐｏｎ．ｃｏ．ｊｐ／ＭｉｄｎｉｇｈｔＡｖｅｎｕｅ／」の示すページに接続するが、２００８年７月１０日４：０５に「ＦＭ日本」を選局すると、番組ＵＲＬ情報が「ｈｔｔｐ：／／ｗｗｗ．ｆｍ＿ｎｉｐｐｏｎ．ｃｏ．ｊｐ／ＭｏｒｎｉｎｇＮｅｗｓ／」に接続することになる。したがって、選局した時間帯により同一の番組であっても、異なるサイトページに接続することができる。 As shown in the correspondence relationship T2A shown in FIG. 6, in the correspondence table T2, program URL information related to the broadcasting station 2 “FM Japan” shown in FIG. Based on a plurality of program URL information, the connection destination can be changed according to the time zone. For example, when “FM Japan” is selected at 0:10 on July 10, 2008, the control unit 15 of the broadcast receiving apparatus 10 refers to the correspondence table T2, and the program URL information is “http: // www. fm_nippon.co.jp/MidnightAvenue/ "is connected, but when" FM Japan "is selected at 4:05 on July 10, 2008, the program URL information is" http://www.fm_nippon.co ". .Jp / MorningNews / ". Therefore, the same program can be connected to different site pages depending on the selected time zone.
　図７で示す対応関係Ｔ２Ｂに示すように、対応テーブルＴ２には図６で示した各番組の番組コーナー毎の接続先ＵＲＬ情報が格納されている。図７に示すように、「番組名」が同一であっても、時間帯により当該番組コーナーが変化するため、「番組コーナー名」が複数存在する。そして、これらの「番組コーナー名」に対応したサイトページである「対応コンテンツＵＲＬ」情報が格納されている。図７に示すように番組名「ＭｉｄｎｉｇｈｔＡｖｅｎｕｅ」には、番組コーナー「Ｍｉｄｎｉｇｈｔ　Ｊａｚｚ」と「Ｒｅｌａｘ　Ｓｈｏｐｐｉｎｇ」が存在する。たとえば、番組コーナー「Ｍｉｄｎｉｇｈｔ　Ｊａｚｚ」は、２００８年７月１０日０：００～０：２９までの間の接続先として「ｈｔｔｐ：／／ｗｗｗ．ｆｍ＿ｎｉｐｐｏｎ．ｃｏ．ｊｐ／ＭｉｄｎｉｇｈｔＡｖｅｎｕｅ／ｊａｚｚ」というＵＲＬ情報が格納されている。一方、番組コーナー「Ｒｅｌａｘ　Ｓｈｏｐｐｉｎｇ」は、２００８年７月１０日０：３０～０：５９までの間の接続先として「ｈｔｔｐ：／／ｗｗｗ．ｆｍ＿ｎｉｐｐｏｎ．ｃｏ．ｊｐ／ＭｉｄｎｉｇｈｔＡｖｅｎｕｅ／ｓｈｏｐ０７１０」というＵＲＬ情報が格納されている。 As shown in the correspondence relationship T2B shown in FIG. 7, the correspondence table T2 stores connection destination URL information for each program corner of each program shown in FIG. As shown in FIG. 7, even if the “program name” is the same, the program corner changes depending on the time zone, so there are a plurality of “program corner names”. Then, “corresponding content URL” information which is a site page corresponding to these “program corner names” is stored. As shown in FIG. 7, the program name “MidnightAvenue” includes a program corner “Midnight Jazz” and “Relax Shopping”. For example, the program corner “Midnight Jazz” has URL information “http://www.fm_nippon.co.jp/MidnightAvenue/jazz” as a connection destination between 0:00 and 0:29 on July 10, 2008. Is stored. On the other hand, the program corner “Relax Shopping” has URL information “http://www.fm_nippon.co.jp/MidnightAvenue/shop0710” as a connection destination between 0:30 and 0:59 on July 10, 2008. Is stored.
　図８で示す対応関係Ｔ２Ｃに示すように、対応テーブルＴ２には各番組コーナーの「スポンサー名」と、スポンサーのＨＰなどの接続先を示す「スポンサーＵＲＬ」とが格納されている。たとえば、番組名コーナー「Ｍｉｄｎｉｇｈｔ　Ｊａｚｚ」のスポンサーは「山田楽器」であり、そのスポンサーのＨＰとして「ｈｔｔｐ：／／ｗｗｗ．ｙａｍａｄａｇａｋｋｉ．ｃｏ．ｊｐ」というＵＲＬ情報が格納されている。一方、番組コーナー名「Ｒｅｌａｘ　Ｓｈｏｐｐｉｎｇ」のスポンサーは「快眠枕」であり、そのスポンサーのＨＰとして「ｈｔｔｐ：／／ｗｗｗ．ｒｅｌａｘｓｌｅｅｐ．ｃｏ．ｊｐ」というＵＲＬ情報が格納されている。これらの情報が対応テーブルＴ２に格納されていることにより、たとえば、ユーザが視聴している製品などに興味を抱いたときに、そのスポンサーのＨＰへ接続できるボタンを表示させて、当該スポンサーのＨＰへ誘導することが可能となる。 As shown in the correspondence relationship T2C shown in FIG. 8, the correspondence table T2 stores a “sponsor name” of each program corner and a “sponsor URL” indicating a connection destination such as a sponsor's HP. For example, the sponsor of the program name corner “Midnight Jazz” is “Yamada Musical Instrument”, and URL information “http://www.yamadagakiki.co.jp” is stored as the sponsor's HP. On the other hand, the sponsor of the program corner name “Relax Shopping” is “Sleeping Pillow”, and URL information “http://www.relaxsleep.co.jp” is stored as the sponsor's HP. Since these pieces of information are stored in the correspondence table T2, for example, when the user is interested in the product being viewed, a button that can be connected to the sponsor's HP is displayed, and the sponsor's HP is displayed. It becomes possible to guide to.
　なお、上述した図６～図８に示す対応関係Ｔ２Ａ、Ｔ２Ｂ、Ｔ２Ｃに示すように、対応テーブルＴ２には、時間帯により配信される番組に関連するＵＲＬ情報、当該番組内の番組コーナーに関連するＵＲＬ情報、当該番組のスポンサーに関連するＵＲＬ情報などの複数のＵＲＬ情報が格納されているが、それ以外にも番組ＵＲＬフラグ、番組コーナーＵＲＬフラグ、スポンサーＵＲＬフラグといったそれぞれのＵＲＬ情報の示すページの表示判定用の値（不図示）が格納されている。番組ＵＲＬフラグ、番組コーナーＵＲＬフラグ、スポンサーＵＲＬフラグについては、後述する放送受信装置２０の放送受信方法において説明する。 As shown in the correspondence relationships T2A, T2B, and T2C shown in FIGS. 6 to 8 described above, the correspondence table T2 includes URL information related to a program distributed according to a time slot and a program corner in the program. A plurality of URL information such as URL information related to the program and URL information related to the sponsor of the program are stored. In addition to this, pages indicated by respective URL information such as a program URL flag, a program corner URL flag, and a sponsor URL flag The display determination value (not shown) is stored. The program URL flag, the program corner URL flag, and the sponsor URL flag will be described in the broadcast receiving method of the broadcast receiving device 20 described later.
　（第２実施形態に係る放送受信装置２０の放送受信方法）
　続いて、上述した対応関係Ｔ２Ａ，Ｔ２Ｂ，Ｔ２Ｃを有する対応テーブルＴ２を用いた放送受信装置２０の表示処理について図９～図１４を参照しながら説明する。この放送受信装置２０は、図９に示す表示処理、図１０に示すＷｅｂブラウザ入力表示処理、図１１に示すユーザ表示指示処理、図１２に示すスケジュール情報処理、図１３に示すＵＲＬ情報更新処理を行なう。なお、放送受信装置２０は、放送受信装置１０と同じく選局受付処理も行なっているが、図３で示した第１実施形態の放送受信装置１０の選局受付処理と同一であるため、図示および説明を省略する。以下、各処理について説明する。 (Broadcast receiving method of broadcast receiving apparatus 20 according to the second embodiment)
Next, display processing of the broadcast receiving apparatus 20 using the correspondence table T2 having the correspondence relationships T2A, T2B, and T2C described above will be described with reference to FIGS. The broadcast receiving apparatus 20 performs the display process shown in FIG. 9, the Web browser input display process shown in FIG. 10, the user display instruction process shown in FIG. 11, the schedule information process shown in FIG. 12, and the URL information update process shown in FIG. Do. The broadcast receiving apparatus 20 performs the channel selection reception process in the same manner as the broadcast reception apparatus 10, but is the same as the channel selection reception process of the broadcast reception apparatus 10 of the first embodiment shown in FIG. The description is omitted. Hereinafter, each process will be described.
　図９は、本発明の第２実施形態に係る放送受信装置２０が行なう表示処理を示すフローチャートである。図９に示す放送受信装置２０の表示処理は、図３で示した表示処理と基本的には同じ処理を行なうが、基本ＵＲＬ情報の示すサイトのみを表示するものではなく、時刻情報を取得して、時間帯に応じて表示させるサイトページを決定することができるＷｅｂブラウザ入力表示処理ステップＳ２４を有するものである。Ｗｅｂブラウザ入力表示処理のステップＳ２４の詳細については図１０を参照しながら説明する。なお、他のステップについては、図３で示した表示処理と同一であるため、その説明を省略する。 FIG. 9 is a flowchart showing display processing performed by the broadcast receiving apparatus 20 according to the second embodiment of the present invention. The display processing of the broadcast receiving apparatus 20 shown in FIG. 9 is basically the same as the display processing shown in FIG. 3, but does not display only the site indicated by the basic URL information, but acquires time information. Thus, it has a Web browser input display processing step S24 that can determine a site page to be displayed according to the time zone. Details of step S24 of the Web browser input display process will be described with reference to FIG. The other steps are the same as the display process shown in FIG.
　図１０は、図９で示したステップＳ２４のＷｅｂブラウザ入力表示処理の詳細を示すフローチャートである。Ｗｅｂブラウザ入力表示処理は、図１０に示すようにステップＳ３０～ステップＳ３９の処理を有し、制御部１５が受信した放送データおよび現在時刻から接続先ＵＲＬ情報を特定するものである。なお、以下の説明の各種フラグ判定において「フラグをＯＮにする」とは、表示部１６に当該コンテンツを表示させることを意味し、各種のフラグの初期状態は、ＯＦＦとなっているものとする。以下、Ｗｅｂブラウザ入力表示処理の各ステップについて説明する。 FIG. 10 is a flowchart showing details of the Web browser input display process in step S24 shown in FIG. As shown in FIG. 10, the Web browser input display process includes the processes of steps S30 to S39, and specifies the connection destination URL information from the broadcast data received by the control unit 15 and the current time. In the various flag determinations described below, “turning a flag ON” means that the content is displayed on the display unit 16, and the initial state of various flags is assumed to be OFF. . Hereinafter, each step of the Web browser input display process will be described.
　ＳＴＡＲＴ：制御部１５は、図９で示したステップＳ２４の処理に移行すると、Ｗｅｂブラウザ入力表示処理を開始する。すなわち、対応するＵＲＬ情報が記憶部１３の対応テーブルＴ２に存在する場合、制御部１５は、ステップＳ３０の処理を開始する。 START: When the control unit 15 proceeds to the process of step S24 shown in FIG. 9, it starts the Web browser input display process. That is, when the corresponding URL information exists in the correspondence table T2 of the storage unit 13, the control unit 15 starts the process of step S30.
　ステップＳ３０：制御部１５は、放送局２より受信した放送データにスケジュールＵＲＬ情報があるか否かを判定する。ここで、スケジュールＵＲＬ情報とは、図６～図８で示した番組に関連するＵＲＬ情報、番組コーナーに関連するＵＲＬ情報、スポンサーに関連するＵＲＬ情報の総称を意味する。制御部１５は、放送局２より受信した放送データにスケジュールＵＲＬ情報があると判定した（ステップＳ３０でＹＥＳ）ときは、ステップＳ３１の処理へ移行する。一方、制御部１５は、放送局２より受信した放送データにスケジュールＵＲＬ情報がないと判定した（ステップＳ３０でＮＯ）ときは、ステップＳ３２の処理へ移行する。 Step S30: The control unit 15 determines whether the broadcast data received from the broadcast station 2 includes schedule URL information. Here, the schedule URL information means a generic name of URL information related to the program shown in FIGS. 6 to 8, URL information related to the program corner, and URL information related to the sponsor. When the control unit 15 determines that the broadcast data received from the broadcast station 2 includes schedule URL information (YES in step S30), the control unit 15 proceeds to the process of step S31. On the other hand, when the control unit 15 determines that the broadcast data received from the broadcast station 2 has no schedule URL information (NO in step S30), the control unit 15 proceeds to the process of step S32.
　ステップＳ３１：制御部１５は、現在時刻に対応した番組ＵＲＬ情報があるか否かを判定する。具体的には、制御部１５は記憶部１３に記憶された対応テーブルＴ２を参照して判定を行なう。制御部１５は、現在時刻に対応した番組ＵＲＬ情報があると判定したとき（ステップＳ３１でＹＥＳ）は、ステップＳ３４の処理へ移行する。一方、制御部１５は、現在時刻に対応した番組ＵＲＬ情報がないと判定したとき（ステップＳ３１でＮＯ）は、ステップＳ３５の処理へ移行する。 Step S31: The control unit 15 determines whether there is program URL information corresponding to the current time. Specifically, the control unit 15 makes a determination with reference to the correspondence table T2 stored in the storage unit 13. When the control unit 15 determines that there is program URL information corresponding to the current time (YES in step S31), the control unit 15 proceeds to processing in step S34. On the other hand, when the control unit 15 determines that there is no program URL information corresponding to the current time (NO in step S31), the process proceeds to step S35.
　ステップＳ３２：制御部１５は、Ｗｅｂブラウザを起動し、基本ＵＲＬ情報の示すサイトへ接続する。そして、制御部１５は、ステップＳ３３の処理へ移行する。 Step S32: The control unit 15 starts the Web browser and connects to the site indicated by the basic URL information. And the control part 15 transfers to the process of step S33.
　ステップＳ３３：制御部１５は、図９に示す表示処理へと移行する。具体的には、制御部１５は、図９に示すステップＳ２５の処理へ移行する。 Step S33: The control unit 15 proceeds to the display process shown in FIG. Specifically, the control unit 15 proceeds to the process of step S25 shown in FIG.
　ステップＳ３４：制御部１５は、記憶部１３に記憶されている対応テーブルＴ２内の番組ＵＲＬフラグをＯＮにする。そして、制御部１５は、ステップＳ３５へ処理を移行する。 Step S34: The control unit 15 turns on the program URL flag in the correspondence table T2 stored in the storage unit 13. And the control part 15 transfers a process to step S35.
　ステップＳ３５：制御部１５は、現在時刻に対応した番組コーナーＵＲＬ情報があるか否かを判定する。制御部１５は、現在時刻に対応した番組コーナーＵＲＬ情報があると判定したとき（ステップＳ３５でＹＥＳ）は、ステップＳ３６へ処理を移行する。一方、制御部１５は、現在時刻に対応した番組コーナーＵＲＬ情報がないと判定したとき（ステップＳ３５でＮＯ）は、ステップＳ３７の処理へ移行する。 Step S35: The control unit 15 determines whether there is program corner URL information corresponding to the current time. When the control unit 15 determines that there is program corner URL information corresponding to the current time (YES in step S35), the process proceeds to step S36. On the other hand, when the control unit 15 determines that there is no program corner URL information corresponding to the current time (NO in step S35), the process proceeds to step S37.
　ステップＳ３６：制御部１５は、記憶部１３に記憶されている対応テーブルＴ２内の番組コーナーに対応したＵＲＬフラグをＯＮにする。そして、制御部１５は、ステップＳ３７へ処理を移行する。 Step S36: The control unit 15 turns on the URL flag corresponding to the program corner in the correspondence table T2 stored in the storage unit 13. And the control part 15 transfers a process to step S37.
　ステップＳ３７：制御部１５は、現在時刻に対応したスポンサーＵＲＬ情報があるか否かを判定する。制御部１５は、現在時刻に対応したスポンサーＵＲＬ情報があると判定したとき（ステップＳ３７でＹＥＳ）は、ステップＳ３８へ処理を移行する。一方、制御部１５は、現在時刻に対応したスポンサーＵＲＬ情報がないと判定したとき（ステップＳ３７でＮＯ）は、ステップＳ３９の処理へ移行する。 Step S37: The control unit 15 determines whether there is sponsor URL information corresponding to the current time. When it is determined that there is sponsor URL information corresponding to the current time (YES in step S37), the control unit 15 proceeds to step S38. On the other hand, when the control unit 15 determines that there is no sponsor URL information corresponding to the current time (NO in step S37), the control unit 15 proceeds to the process of step S39.
　ステップＳ３８：制御部１５は、記憶部１３に記憶されている対応テーブルＴ２内のスポンサーに関連したＵＲＬフラグをＯＮにする。そして、制御部１５は、ステップＳ３９へ処理を移行する。 Step S38: The control unit 15 turns on the URL flag related to the sponsor in the correspondence table T2 stored in the storage unit 13. And the control part 15 transfers a process to step S39.
　ステップＳ３９：制御部１５は、ユーザ表示指示処理へと移行する。なお、ユーザ表示指示処理の詳細については図１１を参照しながら説明する。 Step S39: The control unit 15 proceeds to a user display instruction process. Details of the user display instruction process will be described with reference to FIG.
　図１１は、図１０で示したステップＳ３９のユーザ表示指示処理の詳細を示すフローチャートである。ユーザ表示指示処理は、図１１に示すようにステップＳ４０～ステップＳ４６までの処理を有し、予め設定された表示設定に加えてユーザからの表示指示を受け付けてその表示内容を変更するものである。以下、ユーザ表示指示処理の各ステップについて説明する。 FIG. 11 is a flowchart showing details of the user display instruction process in step S39 shown in FIG. As shown in FIG. 11, the user display instruction process includes processes from step S40 to step S46, and accepts a display instruction from the user in addition to a preset display setting, and changes the display contents. . Hereinafter, each step of the user display instruction process will be described.
　ＳＴＡＲＴ：制御部１５は、図１０で示したステップＳ３９の処理へ移行すると、ユーザ表示指示処理を開始する。具体的には、制御部１５は、各種のフラグ判定処理が終了するとステップＳ４０の処理を開始する。 START: When the control unit 15 proceeds to the process of step S39 shown in FIG. 10, it starts the user display instruction process. Specifically, the control unit 15 starts the process of step S40 when various flag determination processes are completed.
　ステップＳ４０：制御部１５は、基本ＵＲＬ情報の示すサイトと、フラグがＯＮとなった各種ＵＲＬ情報に接続できるボタンとを表示部１６に表示する。そして、制御部１５はステップＳ４１の処理へ移行する。 Step S40: The control unit 15 displays on the display unit 16 the site indicated by the basic URL information and buttons that can be connected to various URL information for which the flag is ON. And the control part 15 transfers to the process of step S41.
　ステップＳ４１：制御部１５は、ユーザからの選択有無の確認を行なう。具体的には、制御部１５はステップＳ４０で表示したボタンをユーザが押下したか否かを判定する。制御部１５は、ユーザからの選択がなかったと判定したとき（ステップＳ４１でＮｏ）は、ステップＳ４２へ処理を移行する。一方、制御部１５は、ユーザからの選択があったと判定したとき（ステップＳ４１でＹＥＳ）は、ステップＳ４３へ処理を移行する。 Step S41: The control unit 15 confirms the presence / absence of selection from the user. Specifically, the control unit 15 determines whether or not the user has pressed the button displayed in step S40.

　（第４実施形態に係る放送受信装置４０）
　続いて、本発明の第４実施形態に係る放送受信装置４０について説明する。上述した放送受信システム１ではクライアント・サーバ（Ｃ／Ｓ）方式のコンピュータネットワーク形態を採用していたが、この放送受信装置４０を有する放送受信システム１Ａでは、ピアツーピア（Ｐｅｅｒ　Ｔｏ　Ｐｅｅｒ、以下「Ｐ２Ｐ」とする）方式のコンピュータネットワーク形態を採用している。 (Broadcast receiving device 40 according to the fourth embodiment)
Next, the broadcast receiving device 40 according to the fourth embodiment of the present invention will be described. In the broadcast receiving system 1 described above, a client / server (C / S) type computer network form is adopted. However, in the broadcast receiving system 1A having the broadcast receiving apparatus 40, peer-to-peer (hereinafter referred to as “P2P”). Computer network form.
　図１６は、本発明の第４実施形態に係る放送受信装置４０を含む放送受信システム１Ａの全体構成を示すブロック図である。放送受信システム１Ａにおいて、放送局サーバ３Ａは、放送局２の放送番組や放送コーナー、放送時間帯に対応した各種コンテンツ（動画ファイル、画像ファイル、音声ファイルなど、以下単に「コンテンツ」という）、および当該コンテンツのアドレス情報（当該コンテンツに接続できるＵＲＬ情報、ＩＰアドレス情報、または当該コンテンツデータを保持しているノード情報など、以下単に「コンテンツ取得情報」という）などが記録された複数のテーブルを有するリレーショナルデータベースＤ１を備えているインデックスサーバとして機能している。したがって、放送受信システム１Ａは、放送局サーバ３Ａをインデックスサーバとすると共に、複数の放送受信装置４０をノード（ピア）として機能させている、いわゆるハイブリッド型のＰ２Ｐ形態である。なお、第４実施形態に係る放送受信システム１Ａは、放送受信装置４０の動作および放送局サーバ３Ａ以外の構成は、図１に示す放送受信システム１と同一であるため、同一の符号を付し、各構成の機能および動作についての説明は省略する。 FIG. 16 is a block diagram showing an overall configuration of a broadcast receiving system 1A including a broadcast receiving device 40 according to the fourth embodiment of the present invention. In the broadcast receiving system 1A, the broadcast station server 3A includes various contents (video files, image files, audio files, etc., hereinafter simply referred to as “contents”) corresponding to the broadcast program, broadcast corner, and broadcast time zone of the broadcast station 2, and It has a plurality of tables in which address information of the content (URL information that can be connected to the content, IP address information, or node information that holds the content data, hereinafter simply referred to as “content acquisition information”), and the like are recorded. It functions as an index server provided with a relational database D1. Therefore, the broadcast receiving system 1A is a so-called hybrid P2P form in which the broadcast station server 3A is an index server and a plurality of broadcast receiving apparatuses 40 are functioning as nodes (peers). The broadcast receiving system 1A according to the fourth embodiment is the same as the broadcast receiving system 1 shown in FIG. 1 because the operation of the broadcast receiving device 40 and the configuration other than the broadcast station server 3A are the same as those in FIG. The description of the function and operation of each component is omitted.
　放送受信装置４０の記憶部１３には、ハイブリッド型のＰ２Ｐファイル共有アプリケーション（不図示）が記録されている。このハイブリッド型のＰ２Ｐファイル共有アプリケーションは、インデックスサーバとしての放送局サーバ３Ａに上述したコンテンツの所在を検索できる検索クエリ情報を送信し、所望のコンテンツ取得情報またはコンテンツデータそのものを取得することができるものである。なお、ここで検索クエリ情報とは、放送局サーバ３ＡのリレーショナルデータベースＤ１に対して上述したコンテンツ取得情報を検索できる抽出条件式が記載された文字列であり、たとえば、「放送局名＋日付＋放送開始時刻」に該当するコンテンツ取得情報を抽出する条件式が記述されている。 A hybrid P2P file sharing application (not shown) is recorded in the storage unit 13 of the broadcast receiving apparatus 40. This hybrid P2P file sharing application can transmit the search query information that can search for the location of the content described above to the broadcast station server 3A as an index server, and can acquire desired content acquisition information or content data itself. It is. Here, the search query information is a character string that describes an extraction condition expression that can search the above-described content acquisition information with respect to the relational database D1 of the broadcast station server 3A. For example, “search station name + date + A conditional expression for extracting content acquisition information corresponding to “broadcast start time” is described.
　この検索クエリ情報は、たとえばＳＱＬ（Ｓｔｒｕｃｔｕｒｅｄ　Ｑｕｅｒｙ　Ｌａｎｇｕａｇｅ）などのプログラム言語で記述することができる。また、この検索クエリ情報は、図２の対応テーブルＴ１の「基本ＵＲＬ情報」の代わりに放送局２の名称を抽出条件とした文字列が記録されているものであり、何度でも使用することが可能である。 This search query information can be described in a program language such as SQL (Structured Query Language). The search query information is recorded with a character string using the name of the broadcasting station 2 as an extraction condition instead of the “basic URL information” in the correspondence table T1 of FIG. Is possible.
　また、この検索クエリ情報は、図６～図８に示す対応テーブルＴ２の「番組ＵＲＬ」の代わりに「放送局２の名称＋日付＋開始時刻＋番組名」を抽出条件とした文字列、「番組コーナーＵＲＬ」の代わりに、「放送局２の名称＋日付＋開始時刻＋番組コーナー名」を抽出条件とした文字列、「スポンサーＵＲＬ」の代わりに「放送局２の名称＋日付＋開始時刻＋スポンサー名」などがそれぞれ記録されているものであり、時刻に応じてこれらの抽出条件式が記載された文字列からなるこれらの検索クエリ情報の中から一つ選択され、選択された検索クエリ情報を放送局サーバ３Ａに送信することができる。なお、放送局２から配信される放送データに重畳させて送信されてきた検索クエリ情報に放送受信装置３０側で予め決められたルールにより具体的な抽出条件式に変更した検索クエリ情報を対応テーブルＴ１に記録すると共に、変更した検索クエリ情報を放送局サーバ３Ａに送信することとしてもよい。たとえば、放送受信装置４０は、「放送局２の名称＋日付+番組名」で検索する抽出条件式を放送局２の放送データから取得した場合、更に番組コーナー名やスポンサー名などを限定した抽出条件とした検索クエリ情報を生成し、放送局サーバ３Ａに送信することとしてもよい。 Further, this search query information includes a character string having “broadcast station 2 name + date + start time + program name” as an extraction condition instead of “program URL” in the correspondence table T2 shown in FIGS. A character string using “broadcasting station 2 name + date + start time + program corner name” as an extraction condition instead of “program corner URL”, and “broadcasting station 2 name + date + start time” instead of “sponsor URL” + Sponsor name "etc. are recorded, and one selected from these search query information consisting of a character string in which these extraction condition expressions are described according to the time, and the selected search query Information can be transmitted to the broadcasting station server 3A. Note that the search query information that is transmitted by being superimposed on the broadcast data distributed from the broadcasting station 2 is changed to a search table that has been changed to a specific extraction condition expression according to a rule determined in advance by the broadcast receiving device 30 side. It is good also as transmitting changed search query information to 3 A of broadcast station servers while recording on T1. For example, when the broadcast receiving device 40 obtains an extraction condition expression for searching for “broadcast station 2 name + date + program name” from broadcast data of the broadcast station 2, the broadcast reception apparatus 40 further extracts a program corner name, a sponsor name, and the like. Search query information as a condition may be generated and transmitted to the broadcast station server 3A.
　また、この検索クエリ情報の配布方法としては、放送局２が放送するテレビ放送やラジオ放送の放送データに重畳させて放送受信装置４０へ送信したり、予め、放送受信装置４０に記憶されている放送局サーバ３Ａのアドレス情報に基づいて定期的に放送局サーバ３Ａに接続し、自動的に放送受信装置４０へ送信させたりすることが可能である。 Further, as a method of distributing the search query information, the search query information is transmitted to the broadcast receiving device 40 by being superimposed on the broadcast data of the television broadcast or radio broadcast broadcast by the broadcast station 2, or stored in the broadcast receiving device 40 in advance. It is possible to periodically connect to the broadcast station server 3A based on the address information of the broadcast station server 3A and automatically transmit it to the broadcast receiving apparatus 40.
　放送受信装置４０は、上述した検索クエリ情報を放送局２毎に記憶部１３に保持しており、選局操作に伴って、この検索クエリ情報に基づいてコンテンツ取得情報もしくはコンテンツデータそのものを取得する。なお、放送局サーバ３Ａは上述したコンテンツデータを有しているが、ノードによりコンテンツが一度ダウンロードされると、リレーショナルデータベースＤ１を更新して当該コンテンツの供給先（ダウンロード先のアドレス情報）を当該ノードへと変更してもよい。そして、他のノードから同一のコンテンツの検索要求を受信したときは、当該ノード情報を供給先として応答し、当該コンテンツを保持しているノードからコンテンツを直接ダウンロードさせるようにしてもよい。また、放送受信装置４０も放送局サーバ３Ａが備えているリレーショナルデータベースＤ１を備えて、インデックスサーバとしての機能を果たしてもよい。 The broadcast receiving apparatus 40 holds the above-described search query information in the storage unit 13 for each broadcast station 2, and acquires content acquisition information or content data itself based on the search query information along with a channel selection operation. . The broadcast station server 3A has the above-described content data. However, once the content is downloaded by the node, the relational database D1 is updated and the content supply destination (address information of the download destination) is changed to the node. You may change to When a search request for the same content is received from another node, the node information may be returned as a supply destination, and the content may be directly downloaded from the node holding the content. Also, the broadcast receiving device 40 may include the relational database D1 provided in the broadcast station server 3A, and may serve as an index server.
　このようなハイブリッド型のＰ２Ｐ形態を利用した放送受信装置４０は、上述した放送受信装置１０の有する効果に加えて、放送局サーバ３Ａと各ノード間のネットワークトラフィックの軽減が図れると共に、放送受信装置４０が所望するコンテンツを取得するまでの所要時間を短縮することが可能となる。 The broadcast receiving apparatus 40 using such a hybrid P2P configuration can reduce the network traffic between the broadcast station server 3A and each node in addition to the effects of the broadcast receiving apparatus 10 described above, and the broadcast receiving apparatus. It is possible to shorten the time required until the desired content is acquired by 40.

Get node information.
　図１８は、図１６に示す第４実施形態に係る放送受信システム１Ｂにおける検索処理を概念的に示した図である。なお、図１８に示すように、放送受信装置４０Ａは、放送局サーバ３Ａおよび放送受信装置４０Ｂとの論理的接続（ＬＬ１）が確立しているＰ２Ｐネットワークが構築されているものとする。また、インデックスサーバとしての放送局サーバ３Ａは、ノードである放送受信装置４０Ａから問い合わせ要求（ＱｕｅｒｙメッセージＱＭ１）を受信すると、その問い合わせに対する検索結果（ＱｕｅｒｙＨｉｔメッセージＱＨＭ１）を放送受信装置４０Ａに返すものとする。そして、放送受信装置４０Ａは、検索結果に基づいて、該当するノードもしくは放送局サーバ３Ａへダウンロード要求（ＰｕｓｈメッセージＰＭ１）を行い、該当コンテンツをダウンロードするものである。以下、具体的に説明する。 FIG. 18 is a diagram conceptually showing search processing in the broadcast receiving system 1B according to the fourth embodiment shown in FIG. As shown in FIG. 18, it is assumed that the broadcast receiving apparatus 40A has a P2P network in which a logical connection (LL1) is established between the broadcast station server 3A and the broadcast receiving apparatus 40B. When the broadcast station server 3A as an index server receives an inquiry request (Query message QM1) from the broadcast receiving device 40A as a node, the broadcast station server 3A returns a search result (QueryHit message QHM1) for the inquiry to the broadcast receiving device 40A. To do. Then, the broadcast receiving device 40A makes a download request (Push message PM1) to the corresponding node or the broadcast station server 3A based on the search result, and downloads the corresponding content. This will be specifically described below.
　放送受信装置４０Ａの通信制御部１２は、制御部１５の指示により上述した検索クエリ情報をＱｕｅｒｙメッセージＱＭ１として放送局サーバ３Ａへ送信する。すると、このＱｕｅｒｙメッセージＱＭ１を受信した放送局サーバ３Ａは、リレーショナルデータベースＤ１の検索結果をＱｕｅｒｙＨｉｔメッセージＱＨ１としてＱuｅｒｙメッセージＱＭ１と同じ経路（放送局サーバ３Ａ→法送受信装置３０Ａ）で放送受信装置４０Ａへ送信する。 The communication control unit 12 of the broadcast receiving apparatus 40A transmits the search query information described above as a query message QM1 to the broadcast station server 3A according to an instruction from the control unit 15. Then, the broadcast station server 3A that has received this Query message QM1 transmits the search result of the relational database D1 as a QueryHit message QH1 to the broadcast reception device 40A through the same path as the Query message QM1 (broadcast station server 3A → legal transmission / reception device 30A).

Therefore, content related to broadcast data can be easily acquired without the user performing a predetermined operation every time in addition to the channel selection operation. Although the display process is performed in step S75 of the broadcast reception method of the broadcast receiving apparatus 40, if the content is an image file or a moving image file, the download process (records the corresponding data in the storage unit 13) in step S74. The processing may be completed only by (processing).
　（第５実施形態に係る放送受信装置５０）
　続いて、本発明の第５実施形態に係る放送受信装置５０について説明する。第４の実施形態に係る放送受信装置５０を含む放送受信システム１Ｂは、上述した放送受信システム１Ａと同じＰ２Ｐ型のコンピュータネットワーク形態を採用しているが、放送局サーバ３Ｂがインデックスサーバとして機能しない。つまり、放送受信装置５０を含む放送受信システム１Ｂは、リレーショナルデータベースＤ１を有さず、いわゆるピュア型のＰ２Ｐ形態を採用している。なお、第５実施形態に係る放送受信システム１Ｂは、放送局サーバ３ＢがリレーショナルデータベースＤ１を有さない点以外の構成は、図１６に示す放送受信システム１Ａと同一であるため、図示および各構成の説明は省略する。 (Broadcast receiving device 50 according to the fifth embodiment)
Subsequently, a broadcast receiving device 50 according to a fifth embodiment of the present invention will be described. The broadcast receiving system 1B including the broadcast receiving device 50 according to the fourth embodiment employs the same P2P type computer network form as the above-described broadcast receiving system 1A, but the broadcast station server 3B does not function as an index server. . That is, the broadcast receiving system 1B including the broadcast receiving device 50 does not have the relational database D1, and adopts a so-called pure P2P form. The broadcast receiving system 1B according to the fifth embodiment is the same as the broadcast receiving system 1A shown in FIG. 16 except for the point that the broadcast station server 3B does not have the relational database D1. Description of is omitted.
　放送受信装置５０の記憶部１３には、上述したコンテンツの所在を検索できる検索クエリ情報を作成する共に、当該検索クエリ情報に基づいて所望のコンテンツを取得することができるピュア型のＰ２Ｐファイル共有アプリケーション（不図示）が記録されている。ピュア型のＰ２Ｐファイル共有アプリケーションは、他のノードに対して、生成した検索クエリ情報を生成してブロードキャストを行なうことで所望のコンテンツデータのアドレス情報またはコンテンツデータそのものを取得することが可能となっている。なお、ここで検索クエリ情報とは、上述した第４実施形態における検索クエリ情報と同義であるため、説明を省略する。 In the storage unit 13 of the broadcast receiving device 50, a pure P2P file sharing application that creates search query information that can search for the location of the content described above and that can acquire desired content based on the search query information. (Not shown) is recorded. The pure type P2P file sharing application can acquire the address information of the desired content data or the content data itself by generating the generated search query information and broadcasting to other nodes. Yes. Here, the search query information is synonymous with the search query information in the above-described fourth embodiment, and a description thereof will be omitted.
　このようなピュア型のＰ２Ｐ形態を利用した放送受信装置５０は、上述した放送受信装置１０の有する効果に加えて、放送局サーバ３Ｂと各ノード間のネットワークトラフィックの軽減が図ることができる。 The broadcast receiving apparatus 50 using such a pure P2P configuration can reduce network traffic between the broadcast station server 3B and each node in addition to the effects of the broadcast receiving apparatus 10 described above.
　（第５実施形態に係る放送受信装置５０の放送受信方法）
　続いて、図１９を参照しながら、放送受信装置５０の動作について説明する。図１９は、本発明の第５実施形態に係る放送受信装置５０の選局受付処理およびコンテンツ取得処理を示すフローチャートである。なお、図１９に示すフローチャートのうちＳＴＡＲＴ～ステップＳ８２までの処理は、図３に示すフローチャートのＳＴＡＲＴ～ステップＳ３までの処理と、ステップＳ８９の処理は、図１７に示すステップＳ７５の処理と、ステップＳ９０の処理は、図３に示すフローチャートのステップＳ７の処理と、それぞれ同一であるため、説明を省略する。また、表示部１６に表示される表示結果画面例についても図５もしくは図１４と同一であるため、説明及び図示を省略する。なお、放送受信装置５０の記憶部１３に格納されている対応テーブルＴ１および対応テーブルＴ２には、放送局２がコンテンツ配信をしているか否かを示すコンテンツ配信判定フラグが予め記録されているものとする。 (Broadcast receiving method of the broadcast receiving apparatus 50 according to the fifth embodiment)
Next, the operation of the broadcast receiving device 50 will be described with reference to FIG. FIG. 19 is a flowchart showing channel selection reception processing and content acquisition processing of the broadcast receiving device 50 according to the fifth embodiment of the present invention. In the flowchart shown in FIG. 19, the processing from START to step S82 is the processing from START to step S3 in the flowchart shown in FIG. 3, the processing in step S89 is the processing in step S75 shown in FIG. The process of S90 is the same as the process of step S7 in the flowchart shown in FIG. The display result screen example displayed on the display unit 16 is also the same as that shown in FIG. 5 or FIG. In the correspondence table T1 and the correspondence table T2 stored in the storage unit 13 of the broadcast receiving device 50, a content distribution determination flag indicating whether or not the broadcast station 2 is distributing content is recorded in advance. And
　ステップＳ８３：制御部１５は、選局された放送局２がコンテンツの配信を行なっているか否かの判定処理を行なう。具体的には、制御部１５は、記憶部１３に格納されている対応テーブルＴ１のコンテンツ配信判定フラグを参照して判定する。制御部１５は、選局された放送局２がコンテンツの配信を行なっている（ステップＳ８３でＹＥＳ）場合は、ステップＳ８４の処理へ移行する。一方、制御部１５は、選局された放送局２がコンテンツの配信を行なっていない（ステップＳ８３でＮＯ）場合は、ステップＳ９０の処理へ移行する。 Step S83: The control unit 15 determines whether or not the selected broadcast station 2 is distributing content. Specifically, the control unit 15 makes a determination with reference to the content distribution determination flag in the correspondence table T1 stored in the storage unit 13. If the selected broadcast station 2 is distributing content (YES in step S83), the control unit 15 proceeds to the process of step S84. On the other hand, when the selected broadcast station 2 is not distributing content (NO in step S83), the control unit 15 proceeds to the process of step S90.
　ステップＳ８４：制御部１５は、該当データに関する検索クエリ情報を作成する。具体的には、制御部１５は、上述したピュア型のＰ２Ｐアプリケーションを用いて、検索クエリ情報を自動生成する。たとえば、対応テーブルＴ１から選局された放送局２情報と、内蔵された時計機構（不図示）やネットワーク５経由でＮＴＰサーバなどから現在の時刻情報とを取得して、これらの抽出条件に対応したコンテンツの検索文字列を生成する。制御部１５は、検索クエリ情報の生成が完了するとステップＳ８５の処理へ移行する。 Step S84: The control unit 15 creates search query information related to the corresponding data. Specifically, the control unit 15 automatically generates search query information using the pure P2P application described above. For example, the broadcast station 2 information selected from the correspondence table T1 and the current time information from an NTP server or the like via a built-in clock mechanism (not shown) or the network 5 are acquired, and these extraction conditions are supported. Generate a search string for the selected content. When the generation of the search query information is completed, the control unit 15 proceeds to the process of step S85.
　ステップＳ８５：制御部１５は、通信制御部１２に検索クエリ情報をネットワーク５経由もしくはノード間で直接接続できる方法（無線通信であればアドホックモードなど）で他のノードに問い合わせ要求を送信するように指示する。 Step S85: The control unit 15 transmits an inquiry request to another node by a method (such as ad hoc mode in the case of wireless communication) in which the search query information can be directly connected to the communication control unit 12 via the network 5 or between nodes. Instruct.
　図２０は、本発明の第５実施形態に係る放送受信システム１Ｂにおける検索処理を概念的に示した図である。図２０に示すように、放送受信装置５０Ａは、放送受信装置５０Ｂ、５０Ｃとの論理的接続（ＬＬ１）が確立しており、放送受信装置５０Ｂは放送受信装置５０Ａ，５０Ｄとの論理的接続が確立しているＰ２Ｐネットワークが構築されているものとする。また、放送受信装置５０Ａは、他のすべてのノードへ問い合わせ要求（ＱｕｅｒｙメッセージＱＭ２）を送信すると、他のノードのうち該当するコンテンツを有する放送受信装置はその問い合わせに対する検索結果（ＱｕｅｒｙＨｉｔメッセージＱＨＭ２）を返すものとする。そして、放送受信装置５０Ａは、検索結果に基づいて、該当するノードへダウンロード要求（ＰｕｓｈメッセージＰＭ１）を行い、該当コンテンツをダウンロードするものである。以下、具体的に説明する。 FIG. 20 is a diagram conceptually showing search processing in the broadcast receiving system 1B according to the fifth embodiment of the present invention. As shown in FIG. 20, the broadcast receiving device 50A has established a logical connection (LL1) with the broadcast receiving devices 50B and 50C, and the broadcast receiving device 50B has a logical connection with the broadcast receiving devices 50A and 50D. Assume that an established P2P network is established. When the broadcast receiving device 50A transmits an inquiry request (Query message QM2) to all other nodes, the broadcast receiving device having the corresponding content among the other nodes sends a search result (QueryHit message QHM2) to the inquiry. Shall be returned. Then, the broadcast receiving apparatus 50A makes a download request (Push message PM1) to the corresponding node based on the search result, and downloads the corresponding content. This will be specifically described below.
　図２０に示すように放送受信装置５０Ａの制御部１５は、通信制御部１２に対して上述した検索クエリ情報をＱｕｅｒｙメッセージＱＭ２としてＰ２Ｐネットワーク内の他のノードである放送受信装置５０Ｂ、５０Ｃ、５０Ｄへブロードキャスト送信をするように指示する。制御部１５は、他のノードである放送受信装置５０Ｂ、５０Ｃ、５０Ｄへ問い合わせを行なうとステップＳ８６の処理へ移行する。 As shown in FIG. 20, the control unit 15 of the broadcast receiving device 50A uses the search query information described above for the communication control unit 12 as a query message QM2, and broadcast receiving devices 50B, 50C, and 50D that are other nodes in the P2P network. To send a broadcast. When the control unit 15 makes an inquiry to the broadcast receiving devices 50B, 50C, and 50D, which are other nodes, the control unit 15 proceeds to the process of step S86.
　ステップＳ８６：制御部１５は、合致するデータがあるか否かの判定を行なう。たとえば、図２０に示すように他のノードである放送受信装置５０Ｂ、５０Ｃ、５０ＤからのＱｕｅｒｙＨｉｔメッセージＱＨ２の応答有無を一定期間監視する。制御部１５は、合致するデータがある、すなわち他のノードである放送受信装置５０Ｂ、５０Ｃ、５０Ｄから一定期間内にＱｕｅｒｙＨｉｔメッセージＱＨ２の応答があった場合（ステップＳ８６でＹＥＳ）には、ステップＳ８７の処理へ移行する。一方、制御部１５は、合致するデータがなかった、すなわち他のノードである放送受信装置５０Ｂ、５０Ｃ、５０Ｄから一定期間内にＱｕｅｒｙＨｉｔメッセージＱＨ２の応答がなかった場合（ステップＳ８６でＮＯ）は、ステップＳ８８の処理へ移行する。なお、このＱｕｅｒｙメッセージＱＭ２にはＴＴＬ（Ｔｉｍｅ　Ｔｏ　Ｌｉｖｅ）が設定されており、ＴＴＬが０になった時点でＱｕｅｒｙメッセージＱＭ２は破棄される。 Step S86: The control unit 15 determines whether there is matching data. For example, as shown in FIG. 20, the presence or absence of a response to the QueryHit message QH2 from the broadcast receiving apparatuses 50B, 50C, and 50D, which are other nodes, is monitored for a certain period. When there is matching data, that is, when there is a response to the QueryHit message QH2 within a certain period from the broadcast receiving devices 50B, 50C, 50D which are other nodes (YES in step S86), the control unit 15 performs step S87. Move on to processing. On the other hand, when there is no matching data, that is, when there is no response to the QueryHit message QH2 within a certain period from the broadcast receiving devices 50B, 50C, and 50D that are other nodes (NO in step S86), The process proceeds to step S88. Note that TTL (Time To Live) is set in the Query message QM2, and when the TTL reaches 0, the Query message QM2 is discarded.
　ステップＳ８７：制御部１５は、通信制御部１２に該当コンテンツを保有するノードからデータをダウンロードするように指示し、当該コンテンツデータをダウンロードする。たとえば、図２０に示すようにステップＳ８６においてブロードキャストで送信されたＱｕｅｒｙメッセージＱＭ２を受信した他のノードである放送受信装置５０Ｄが該当コンテンツデータと一致するファイルを保有している場合には、放送受信装置５０Ｄは、検索結果としてＱｕｅｒｙＨｉｔメッセージＱＨ２を、ＱuｅｒｙメッセージＱＭ２と同じ経路（放送受信装置５０Ｄ→放送受信装置５０Ｂ→放送受信装置５０Ａ）で放送受信装置５０Ａに対して送信する。 Step S87: The control unit 15 instructs the communication control unit 12 to download data from the node having the corresponding content, and downloads the content data. For example, as shown in FIG. 20, when the broadcast receiving device 50D, which is another node that has received the Query message QM2 transmitted by broadcasting in step S86, has a file that matches the corresponding content data, broadcast reception is performed. The device 50D transmits the QueryHit message QH2 as a search result to the broadcast receiving device 50A through the same path as the Query message QM2 (broadcast receiving device 50D → broadcast receiving device 50B → broadcast receiving device 50A).
　通信制御部１２は、このＱｕｅｒｙＨｉｔメッセージＱＨ２を受信すると、検索結果から目的のファイルを選択してＰｕｓｈメッセージＰＭ２を放送受信装置５０Ｄに送信してダウンロードを要求する。制御部１５は、該当コンテンツデータのダウンロードが完了するとステップＳ８９の処理へ移行する。 When receiving the QueryHit message QH2, the communication control unit 12 selects a target file from the search result and transmits the Push message PM2 to the broadcast receiving device 50D to request download. When the download of the corresponding content data is completed, the control unit 15 proceeds to the process of step S89.
　ステップＳ８８：制御部１５は、該当データがない旨を通知する。すなわち、表示部１６に該当データがない旨を表示するとステップＳ９０の処理（選局操作受付処理）へ移行する。 Step S88: The control unit 15 notifies that there is no corresponding data. That is, when the display unit 16 displays that there is no corresponding data, the process proceeds to step S90 (channel selection operation reception process).
　このような放送受信装置５０の放送受信方法は、制御部１５の制御により、ユーザの選局操作に応じて、選局受付処理およびコンテンツ取得処理を自動的に行なうため、選局された放送局２に関連するコンテンツを自動的に取得し、表示部１６に表示させることができる。したがって、ユーザが選局操作に加えて所定の操作を毎回行なわなくとも放送データに関連するコンテンツを容易に取得することができる。なお、ステップＳ８９において表示処理を行なっているが、コンテンツが画像ファイルや動画ファイルである場合には、ステップＳ８７のダウンロード処理（記憶部１３に該当データを記録する処理）のみでもよい。 The broadcast receiving method of such a broadcast receiving apparatus 50 is such that a channel selection reception process and a content acquisition process are automatically performed according to the user's channel selection operation under the control of the control unit 15. 2 can be automatically acquired and displayed on the display unit 16. Therefore, content related to broadcast data can be easily acquired without the user performing a predetermined operation every time in addition to the channel selection operation. In addition, although the display process is performed in step S89, when the content is an image file or a moving image file, only the download process (process for recording the corresponding data in the storage unit 13) in step S87 may be performed.
　以上、放送受信装置１０,２０,３０,４０,５０を本発明の実施形態例として説明したが、本発明は、これに限定されるものではなく、発明の要旨を逸脱しない範囲において種々の変形や変更が可能である。 The broadcast receivers 10, 20, 30, 40, and 50 have been described as exemplary embodiments of the present invention.

　たとえば、上述した各実施形態に係る放送受信システム１,１Ａ,１Ｂでは、放送局サーバ３は放送局２が管理・運営するサーバとし、関連企業サーバ４も関連企業が管理・運営するサーバとして説明したが、放送局サーバ３や関連企業サーバ４は、外部のホスティング会社などのサービスを利用する、またはシステム会社などに外部委託して運営されているサーバとしてもよい。 For example, in the broadcast receiving systems 1, 1A and 1B according to the above-described embodiments, the broadcast station server 3 is described as a server managed and operated by the broadcast station 2, and the related company server 4 is also described as a server managed and operated by the related company. However, the broadcast station server 3 and the related company server 4 may be servers that use services such as an external hosting company or are outsourced to a system company.
　また、上述した各実施形態に係る放送受信装置１０，２０，３０,４０,５０では、製品出荷時に予め各放送局２と放送局２に関連する基本ＵＲＬ情報が少なくとも格納されている対応テーブルＴ１、Ｔ２が記憶部１３に記憶されていることとしたが、ユーザが入力部１４を使用して、対応テーブルＴ１，Ｔ２の基本ＵＲＬ情報などを設定する、もしくは更新できるようにしてもよい。 Further, in the broadcast receiving apparatuses 10, 20, 30, 40, 50 according to the above-described embodiments, the correspondence table T1 in which at least basic URL information related to each broadcast station 2 and the broadcast station 2 is stored in advance at the time of product shipment. T2 is stored in the storage unit 13, but the user may use the input unit 14 to set or update the basic URL information of the correspondence tables T1 and T2.
　また、上述した実施形態に係る放送受信装置１０では、選局受付処理において対応するＵＲＬ情報がある場合にＷｅｂブラウザを起動し（図３のステップＳ５）、その後に放送局２のＨＰの表示許可判定を行なっている（図４のステップＳ９）が、選局受付処理段階ではＷｅｂブラウザを起動せず、表示処理段階において放送局２のＨＰの表示が許可されている場合（ステップＳ９でＹＥＳ）にＷｅｂブラウザを起動し、当該ＵＲＬ情報に基づいて接続を行なうこととしてもよい。または、図３に示すステップＳ４の判定条件にＨＰ表示許可判定を追加して判定を行なうこととしてもよい。 Also, in the broadcast receiving apparatus 10 according to the above-described embodiment, when there is corresponding URL information in the channel selection reception process, the web browser is activated (step S5 in FIG. 3), and thereafter the HP display permission of the broadcast station 2 is permitted. When the determination is being made (step S9 in FIG. 4), the web browser is not activated in the channel selection reception processing stage, and the HP display of the broadcasting station 2 is permitted in the display processing stage (YES in step S9).
