Information extracting section 14 for extracting information, information transmitting section 19 for transmitting information to other terminal devices, etc., network I / F (interface) 20 for connecting to home network 40, image display means and sound output means (FIG. (Not shown) includes an image / sound I / F 21 for outputting image and sound signals or information, a control unit 24 for controlling the operation of each of these components, and a storage unit 22. Furthermore, the digital broadcast receiver 10 may include an authentication unit 18 that generates authentication information for the network terminal 60 to authenticate information included in the digital broadcast receiver 10 or the digital broadcast.

  As the receiving unit 12 and the decoding unit 13, components such as a receiving circuit and a decoding circuit (including a part of an integrated circuit element) provided in a known digital television receiver or the like can be used. The storage unit 22 can be used to store the digital broadcast decoded by the decoding unit 13, but is not limited thereto, and may be used to store information or a program for the operation of the control unit or arbitrary information. Good. For example, the storage unit 22 may be used to store a program or API for the digital broadcast receiver 10 to operate as a Java virtual machine.

Information associated with the designated site that can be extracted by the information extraction unit 14 is included in any information that can be included in the digital broadcast 28. For example, the information extraction unit 14 may extract information associated with a designated site from information received as part of a data broadcast included in the digital broadcast 28. Whether the information extraction unit 14 corresponds to the information to be extracted may be determined as a match or mismatch with a predetermined character string or the like, or may be determined based on an identifier associated with the received information.
For example, when the decrypted digital broadcast includes a character string such as “http: //”, the information extraction unit 14 uses the phrase including the character string as a URL for accessing a site specified by the broadcast wave. It may be identified and extracted as information associated with the designated site.
Further, for example, the digital broadcast receiver 10 may store in advance an arbitrary number of URLs and identifiers or character strings corresponding to the URLs using the storage unit 22 or the like. When the decrypted digital broadcast includes such an identifier or a character string, the information extraction unit 14 may extract the corresponding URL as information associated with the designated site.

  The authentication unit 18 can appropriately generate authentication information for the network terminal 60 to authenticate information included in the digital broadcast receiver 10 or the digital broadcast. That is, the digital broadcast receiver 10 may include a mechanism for authentication with the network terminal 60 to transmit information more safely. Any form of authentication can be used as long as it can authenticate information communication from the digital broadcast receiver 10 to the network terminal 60 including the broadband router 50. Generally, as the authentication mode, a known technique that can authenticate one-way information communication from the digital broadcast receiver 10 to an unspecified terminal device can be arbitrarily used.

  The information transmission unit 19 transmits the information extracted by the information extraction unit 14 and the authentication information generated by the authentication unit 18 as appropriate. An identifier, a field, a separator, or the like for distinguishing each information may be added. The digital broadcast receiver 10 may store the IP address in the home network 40 of the network terminal 60 that is the transmission destination using the storage unit 22 or the like. The information transmission unit 19 can transmit information using the stored IP address. Similarly, the Mac address of the network terminal 60 or the terminal name in the home network 40 may be used. Alternatively, the digital broadcast receiver 10 searches whether the network terminal 60 connected in the home network 40 is connectable using a known method such as port scanning, and the network terminal 60 searches for information. A route that can be received may be found and information may be transmitted from the information transmission unit 19. Alternatively, the digital broadcast receiver 10 may transmit information from the information transmission unit 19 by broadcasting.

The network I / F 20 is used to connect the digital broadcast receiver 10 and the broadband router 50 to the network and transmit information from the information transmission unit 19 to the broadband router 50. The image / sound I / F 21 is used to output image and sound signals or information included in the broadcast decoded by the decoding unit 13. As these network I / F 20 and video / audio I / F 21, an interface provided in a known digital television receiver or the like can be arbitrarily used. The image / audio I / F 21 may include a circuit component for outputting video or audio, or may be integrated with the circuit component.
Note that the control unit 24 may output the information transmitted by the information transmission unit 19 only from the network I / F 20, or may output a part or all of the information from the image / sound I / F 21 as data broadcast content. .

  The control unit 24 controls the operations of the reception unit 12, the decoding unit 13, the information extraction unit 14, the authentication unit 18, the information transmission unit 19, the network I / F 20, the image audio I / F 21, and the storage unit 22. To do. A specific control mode will be described later with reference to a flowchart. The control unit 24 may be, for example, a unit in which a television receiver includes a microprocessor and a storage medium, and executes a cooperative reception program according to the present invention.

  Furthermore, the control unit 24 may implement a program or the like that dynamically generates a URL. That is, a broadcasting station or the like that provides the digital broadcast 28 to the cooperative reception system 100 according to the present invention has a link destination or content configuration that can correspond to the line speed, the size of the screen display area of the network terminal, the number of pixels, or the like. Information prepared in advance and associated with the site designated by the broadcast wave may be transmitted to the digital broadcast receiver 10 together with these conditions. The control unit 24 of the digital broadcast receiver 10 may generate a URL to which these conditions are added as additional information. As described above, when the digital broadcast receiver 10 dynamically generates a URL, in the cooperative reception system 100 according to the present invention, various types of network terminals 60 are connected, and content designated by broadcast waves. It is also possible to display character information or image information from the server 32 on the network terminal 60.

  With this configuration, in the cooperative reception system 100 according to the present invention, the digital broadcast receiver 10 is connected to the home network 40 and responds to information associated with the designated site included in the digital broadcast 28. Thus, the information can be transmitted to the network terminal 60 connected to the same home network 40.

  The network terminal 60 is only required to be connected to the home network 40 and receive information transmitted from the digital broadcast receiver 10. The network terminal 60 can automatically access the designated content server 32 in response to receiving information such as a URL included in the decrypted digital broadcast. Therefore, the user can obtain information related to the television broadcast or the like being viewed from the designated content server 32 without needing to input a URL manually.

  By using a personal computer or the like whose constituent elements such as storage capacity or image processing circuit can be changed as necessary as the network terminal 60, performance or function derived from hardware resources possessed by network home appliances or mobile phones Restrictions can be avoided. For example, restrictions on hardware resources of information home appliances, mobile phones, and the like can be avoided with respect to restrictions such as the number of pages that can be temporarily stored, the scroll speed of the display area, and the amount of information that can be displayed on one screen. Therefore, the cooperative reception system 100 according to the present invention can provide a user-friendly reception system to the user.
