Description

明細書  Specification
ディジタル放送受信装置 技術分野 Digital broadcast receiver Technical field
この発明は、 ディジタル放送を受信する受信装置にかかり、 詳しくは、 放送波 に載せたバージョンアッププログラム等をダウンロードできるように構成され たディジタル放送受信装置に関する。 技術背景  The present invention relates to a receiving apparatus for receiving digital broadcasting, and more particularly, to a digital broadcasting receiving apparatus configured to download an upgrade program or the like placed on a broadcast wave. Technology background
例えば、衛星を用いたディジタル放送受信システムにおいては、 ディジタル信 号圧縮技術を用いて映像 ·音声信号を圧縮するとともに、 複数番組の映像 ·音声 ディジタル信号を時分割多重したストリーム （トランスポートストリーム） をト ランスボンダ （衛星中継器） を経由して放送を行っている。 一方、 このようなデ イジタル放送を受信する放送受信装置は、専用のアンテナを通して受け取ったデ イジタル放送の複数のトランスボンダのなかから一つをチューナによって選択 し、 この一^つのトランスボンダに含まれる複数のチャンネルのうち一つをデマル チプレタス処理によつて選択し、 この選択したチヤンネルのディジタル信号をデ コードすることによって映像 ·音声信号を出力するようになっている。  For example, in a digital broadcast receiving system using satellites, video and audio signals are compressed using digital signal compression technology, and a stream (transport stream) obtained by time-division multiplexing the video and audio digital signals of a plurality of programs. It broadcasts via transbonders (satellite repeaters). On the other hand, a broadcast receiving device that receives such a digital broadcast selects one of a plurality of transbonders of the digital broadcast received through a dedicated antenna by a tuner, and includes the transponder in the one transponder. One of a plurality of channels is selected by a demultiplexing process, and a video / audio signal is output by decoding a digital signal of the selected channel.
ところで、 このようなディジタルテレビ放送では、 受信装置のソフトウェアの バグ修正や機能向上のために新しいソフトウェアや共通データ （事業者ロゴ、 ジ ヤンルコード等） のダウンロードデータが放送波に载せられて伝送される。 受信 装置は、 電源 O Nされた時に、 伝送されるダウンロード送出情報 （対応する機種 情報 （m o d e l— i d ) 、.送られてくるダウンロードデータのバージョン （v e r s i o n— i d ) 、 送出日程等） を受信し、 ダウンロードデータが有効かど うかの判定、及び受信装置の設定条件を基にダウン口一ド処理を行うかどうかの 決定を行う。 受信装置の設定条件とは、ダウンロードを実行するかどうかのユーザーの意思 であり、 ダウンロードは行わないとするユーザー設定の下では、 ダウンロード処 理は行わないことになる。一方、ダウンロードを実行すると判断した受信装置は、 送出日程内の設定された日時に送出されるダウンロードデータを受信し、例えば、 フラッシュメモリ等の不揮発性メモリに書き込み、 次回の立ち上げ時等に、 書き 込んだデータを利用することで、 ソフトウエアや共通データのパージヨンアップ を実現している。 By the way, in such digital television broadcasting, download data of new software and common data (business logo, genre code, etc.) is transmitted in broadcast waves in order to fix bugs and improve functions of the software of the receiving device. You. When the power is turned on, the receiving device receives transmitted download information (corresponding model information (model-id), transmitted download data version (version-id), transmission schedule, etc.) Judge whether the download data is valid, and decide whether to perform the download process based on the setting conditions of the receiving device. The setting condition of the receiving device is the user's intention to execute the download, and the download process is not performed under the user setting of not performing the download. On the other hand, the receiving device that determines that the download is to be performed receives the download data transmitted at the set date and time in the transmission schedule, and writes the downloaded data to, for example, a nonvolatile memory such as a flash memory. By using the written data, purging up software and common data is realized.
しかしながら、 ダウンロード送出期間は一定期間に設定されるため、 その期間 において受信装置が電源 O F Fの状態であったり、受信装置の設定条件がダウン ロードは行わないとの設定になっていた場合、 ダウンロードは実行されないこと になる。 ダウンロードデータ等を放送波に載せることを依頼する側である受信装 置の製造事業者の側では、受信装置の設定や電源 O NZO F Fの状態がどのよう になっているかを知ることはできない。 従って、 ダウンロードが実行されていな レ、受信装置が多く存在しているままで前記一定期間が終了したときには、多くの ユーザーからバージョンアップ等の要請がよせられると考えられ、 この場合には サービスマンによる受信装置個々の対応が必要になってしまう。  However, since the download transmission period is set to a fixed period, if the receiving device is powered off during that period, or if the setting conditions of the receiving device are such that the download is not performed, the download will not be performed. It will not be executed. The manufacturer of the receiving device that requests download data and the like on the broadcast wave cannot know the setting of the receiving device or the state of the power supply ONZOFF. Therefore, when the download is not being executed and the fixed period ends with many receiving devices, it is considered that many users may request a version upgrade or the like. Therefore, it is necessary to cope with each receiving device.
この発明は、 上記の事情に鑑み、 ダウンロード送出の一定期間を最適に設定す ることを可能とするディジタル放送受信装置を提供することを目的とする。 発明の開示  The present invention has been made in view of the above circumstances, and has as its object to provide a digital broadcast receiving apparatus capable of optimally setting a fixed period of download transmission.

It is characterized by comprising means for generating device information including information indicating whether or not the device information has been transmitted, and means for transmitting the device information to a preset partner via a telephone line. The preset partner is preferably a facility of a manufacturer of the device. With the above configuration, information indicating whether or not the download has been performed should be sent to, for example, the facility of the manufacturer (for example, an information collection center) via a telephone line, and information on whether or not the download has been completed should be collected. become. For example, if the downloaded percentage of the total number of notifications is below the specified value, the download period is extended, and if it exceeds the specified value, it will end when the scheduled period ends. Measures can be taken.
機器情報として当該装置の製造番号を含めるのがよい。 これによれば、 製造番 号に基づき、或るモデノレ用のソフトウェアのダウンロードの期間は延長し、 別の モデ 用のソフトウェアのダウンロードの期間は予定通りとするといった措置 を採ることができる。 また、 ユーザーからの問い合わせに対して、 その製造番号 を聞き、 この製造番号に基づいてユーザーの受信装置がダウンロード済みかどう かの情報を得ることができるので、 ダウンロードを行っていない場合には、 「ダ ゥンロードを行う設定にして下さい」 といった迅速且つ適正な対応をオペレータ は採ることができる。  It is preferable to include the serial number of the device as device information. According to this, it is possible to take measures such that the download period of the software for one model is extended and the download period of the software for another model is on schedule, based on the production number.
