　ステップＳ１２５において、ステップＳ１２３にて停止したチャンネルのＴＶ放送２３０の提供を停止するようＩＰＴＶサービス事業者２００に要求し、ＩＰＴＶサービス事業者２００からの前記チャンネルのＴＶ放送２３０の提供を停止する。 In step S125, the IPTV service provider 200 is requested to stop providing the TV broadcast 230 of the channel stopped in step S123, and the provision of the TV broadcast 230 of the channel from the IPTV service provider 200 is stopped.
　上記の図１０～１２では、ユーザ１００から視聴終了の操作があった場合にＴＶ放送２３０の配信を停止する場合について説明したが、ユーザ１００が他のチャンネルを選択する操作を行った場合、あるいは他の画面に遷移する操作（例えば、図８においてメインメニュー画面を表示させる操作）を行った場合であっても、当該操作を行った端末へのＴＶ放送２３０の配信が停止される。 In FIGS. 10 to 12 described above, the case where distribution of the TV broadcast 230 is stopped when the user 100 performs an operation for ending viewing / listening is described. However, when the user 100 performs an operation for selecting another channel, Even when an operation for changing to another screen (for example, an operation for displaying the main menu screen in FIG. 8) is performed, distribution of the TV broadcast 230 to the terminal that performed the operation is stopped.
　以上のことから、本実施の形態１によれば、ＩＰＴＶサービス事業者２００から提供される複数のＴＶ放送２３０の同時配信が可能となり、ＰＣ３００、タブレット端末３１０、スマートフォン３２０、およびＴＶアダプタ３３０の各々において、ＩＰＴＶサービス事業者２００から提供されたＴＶ放送２３０を同時に視聴することができる。また、ＰＣ３００、タブレット端末３１０、スマートフォン３２０、およびＴＶアダプタ３３０の各々のユーザ１００は、他の端末へのＴＶ放送２３０の配信に関係なく、任意にＴＶ放送２３０の配信を停止して視聴を終了することが可能となる。すなわち、ＩＰＴＶサービス事業者２００から配信されたＴＶ放送２３０を宅内ネットワークから簡易に視聴することが可能となる。 As described above, according to the first embodiment, a plurality of TV broadcasts 230 provided from the IPTV service provider 200 can be simultaneously distributed, and each of the PC 300, the tablet terminal 310, the smartphone 320, and the TV adapter 330 is provided. The TV broadcast 230 provided by the IPTV service provider 200 can be viewed simultaneously. In addition, each user 100 of the PC 300, the tablet terminal 310, the smartphone 320, and the TV adapter 330 arbitrarily stops the distribution of the TV broadcast 230 and ends the viewing regardless of the distribution of the TV broadcast 230 to other terminals. It becomes possible to do. That is, the TV broadcast 230 distributed from the IPTV service provider 200 can be easily viewed from the home network.
　また、ユーザ宅１０１に専用のＳＴＢが必要な既設の宅内ネットワーク（例えば、図１９に示す宅内ネットワーク１１０）が存在する場合には、当該既設の宅内ネットワークに宅内配信装置１３０を接続するだけで実施の形態１と同様の効果が得られる。すなわち、ＳＴＢを接続している端末ではこれまで通りサービス事業者から配信されるＴＶ放送２３０を視聴することができるとともに、ＳＴＢを接続していない端末においてもサービス事業者から配信されるＴＶ放送２３０を視聴することができる。このように、受信者を選別する通信仕様を含む宅内既設ネットワークが存在する場合において、当該宅内既設ネットワークに宅内配信装置１３０を接続することによって、宅内既設ネットワークを上述した汎用的な宅内ネットワーク１１０としても機能させてＴＶ放送２３０を配信することができる。 If the user's home 101 has an existing home network that requires a dedicated STB (for example, the home network 110 shown in FIG. 19), it is simply performed by connecting the home delivery device 130 to the existing home network. The same effect as in the first embodiment can be obtained. That is, the terminal connected to the STB can still watch the TV broadcast 230 distributed from the service provider, and the TV broadcast 230 distributed from the service provider also to the terminal not connected to the STB. Can be watched. In this way, in the case where there is an existing home network including communication specifications for selecting recipients, by connecting the home delivery device 130 to the existing home network, the existing home network is used as the general-purpose home network 110 described above. Can also function to distribute the TV broadcast 230.
　また、宅内配信装置１３０における新たな機能の拡張や既存の機能の修正は、端末が宅内配信装置１３０を制御することによって行うことができる。ここでいう機能の拡張や修正とは、例えば図５，８に示すようなＧＵＩ画面３０２のデザインの修正や選択ボタンの追加等をいう。 In addition, the extension of new functions and the modification of existing functions in the home delivery device 130 can be performed by the terminal controlling the home delivery device 130. The function expansion or correction here refers to, for example, modification of the design of the GUI screen 302 or addition of a selection button as shown in FIGS.
　具体的には、端末は、ＷＷＷブラウザ３０１を使用して宅内配信装置１３０を制御するための制御コードを含むＨＴＭＬ文書を保持するＷＷＷサーバ４０７にアクセスする。ＷＷＷブラウザ３０１は、ＷＷＷサーバ４０７から取得したＨＴＭＬ文書中に宅内配信装置１３０を制御するための制御コードが含まれている場合は、ＷＷＷサーバ４０７に対して宅内配信装置１３０の制御要求を行う。当該制御要求は、ＷＷＷサーバ４０７からＣＧＩ部４０８に送られ、ＣＧＩ部４０８に制御実行指示が与えられる。ＣＧＩ部４０８は、与えられた制御実行指示に基づいて宅内配信装置１３０を制御する。 Specifically, the terminal uses the WWW browser 301 to access the WWW server 407 that holds an HTML document including a control code for controlling the home delivery device 130. When the HTML document acquired from the WWW server 407 includes a control code for controlling the home delivery device 130, the WWW browser 301 makes a control request for the home delivery device 130 to the WWW server 407. The control request is sent from the WWW server 407 to the CGI unit 408, and a control execution instruction is given to the CGI unit 408. The CGI unit 408 controls the home delivery device 130 based on the given control execution instruction.
　このように、新たな機能の拡張や既存の機能の修正を宅内配信装置１３０で行うことによって、端末はＷＷＷブラウザ３０１以外のユーザインタフェースとしての専用のプログラムを搭載する必要がなくなり、機能の拡張や修正に伴ってプログラムを端末ごとに更新する必要がなくなる。 In this way, by performing expansion of new functions or modification of existing functions by the in-home distribution apparatus 130, the terminal does not need to be equipped with a dedicated program as a user interface other than the WWW browser 301. It is no longer necessary to update the program for each terminal along with the correction.
