Embodiment approach 1

[0041] figure 1 A block diagram for explaining the configuration of the communication system between the satellite digital broadcast receiving apparatus 100 and the management center apparatus 80 according to Embodiment 1 of the present invention. The satellite digital broadcast receiving apparatus 100 according to the first embodiment uses the satellite receiving antenna 110 such as a parabolic antenna to receive the broadcast signal of the satellite digital broadcast, and outputs the image signal and audio signal to the television receiver 140 . The satellite digital broadcast receiving apparatus 100 is characterized in that it has viewing history information of pay broadcasts recorded and stored in the IC card 120 inserted into the card slot 17a of the IC card interface circuit 17 included in the satellite digital broadcast apparatus 100 It is a function of uploading device management information such as these to the management center device 80 of the audiovisual informatio...

Embodiment approach 2

[0071] Figure 15 A block diagram for explaining the configuration of the communication system between the related satellite digital broadcast receiving apparatus 100A and the management center apparatus 80 according to Embodiment 2 of the present invention, Figure 16 to illustrate Figure 15 A block diagram of the detailed configuration of the satellite digital broadcast receiving apparatus 100A.

[0072] The related communication system of Embodiment 2, and figure 1 The characteristic of the communication system is that a VoIP adapter device 150 is inserted between the satellite digital broadcast receiving device 100A and the IP network 50 . That is, if Figure 16 As shown, in the conventional satellite digital broadcast receiving apparatus 100A having the telephone modem 16A for transmitting and receiving apparatus management information and apparatus control information, but not having the VoIP interface circuit 16 of FIG. The VoIP packet transmits and receives device...

Embodiment approach 3

[0077] Figure 18 A block diagram for explaining the configuration of the communication system between the satellite digital broadcast receiving apparatus 100 and the management center apparatus 80 according to Embodiment 3 of the present invention.

[0078] The related communication system of Embodiment 3, and figure 1 The characteristic of the communication system is that the public telephone network 60 is not used, and the access point communication device 70A connected to the IP network 50 has the function of the gateway device 40 . The difference will be described in detail below.

[0079] In this embodiment, the destination recorded in the IC card 120 is not the telephone number of the access point communication apparatus 70A, but the URL or IP address of the access point communication apparatus 70A. It is characterized in that the VoIP interface circuit 16 uses the URL or IP address of the access point communication device 70A to access the access point communication ...
