Further, the DMS 113 has a function of notifying a list of contents stored by itself, and this function is realized by, for example, UPnP “notification (advertisement)”, “transmission of introduction information (description notification)”, etc. Is done.

  Next, the processing operation of the recording reservation system according to the present embodiment will be described with reference to FIGS.

  First, the DMS 113 acquires program guide information from the Internet or TV broadcast radio waves using an EPG (Electronic Program Guide), iEPG (Internet Electronic Program Guide), or the like.

  When the DMS 113 is connected to the HGW apparatus 109, the control point unit 111 of the HGW apparatus 109 automatically recognizes the connection (S201). This DMS detection may be performed by, for example, the discovery function of UPnP (Universal Plug and PLAY).

  The control point unit 111 of the HGW apparatus 109 acquires the program guide information acquired by the DMS 113 (S203). As a method for acquiring the program guide information from the DMS 113, for example, UPnP Content Directory Service or Scheduled Recording Service may be used.

  The reservation screen control unit 115 of the HGW apparatus 109 creates a Web page for a screen for program reservation (program reservation screen, detailed reservation screen, etc.) based on the program guide information acquired by the control point unit 111. The reservation screen control unit 115 embeds the information of the created Web page as XML information in an HTTP packet and PUTs it to the Web server 105 on the Internet. As a result, a Web page for program recording reservation is arranged on the Web server 105 and can be viewed from the user PC 101 connected to the Internet.

  In response to a user operation, the user PC 101 accesses a predetermined program reservation address on the Web server 105 and receives and displays a Web page of a program reservation screen (S207). An example of the program reservation screen is shown in FIG. The user browses the displayed program reservation screen and performs a reservation operation. For example, when the program G on the program reservation screen of FIG. 4 is clicked by the user, the user PC 101 transmits a request corresponding to this click to the Web server 105.

  The Web server 105 transmits a Web page of a detailed reservation screen corresponding to the request from the user PC 101 to the user PC 101. For example, when the program G is clicked on the program reservation screen in the user PC 101, the Web server 105 transmits a Web page of a detailed reservation screen in which information for reserving the program G is embedded to the user PC 101. An example of the detailed reservation screen is shown in FIG. When the user clicks the reservation button on the detailed reservation screen in FIG. 5, the user PC 101 transmits a request corresponding to this click to the Web server 105.

  In response to a request from the user PC 101, the Web server 105 uses each request (date, program name, time, channel, image quality, etc.) displayed on the detailed reservation screen and reservation request information including the media server name as an HTTP information as an HTTP packet. And PUT to the HGW device 109.

  When the HGW apparatus 109 receives the HTTP packet of the reservation request information, the reservation screen control unit 115 analyzes the reservation request information, and acquires reserved program information that specifies the reservation target media server and the reservation target program.

The control point unit 111 of the HGW apparatus 109 makes a recording reservation request to the DMS 113 based on the analyzed reserved program information (S209). The recording reservation request may use, for example, a PnP scheduled recording service.

  As described above, according to the present embodiment, it is possible to make a program recording reservation for DMS in the home network from a user PC outside the home network. The user PC may be a terminal having a browser function, and can make a DMS program recording reservation without adding a special function. Also, any Web server having a function of providing a Web site can be used, and a DMS program recording reservation can be made without adding a special function. Further, the program recording reservation screen and the recording reservation operation can be unified regardless of the type of DMS.
