Abstract

PROBLEM TO BE SOLVED: To make it possible to surely receive reception contract information when an IRD is commonly used in services of plural digital satellite broadcastings. SOLUTION: An EMM packet from a site 2000 of the second satellite management company is transmitted to the side of sites 100A to 100C of the first satellite management company. In the sites of the first satellite management company, the EMM packet of the first satellite management company that are repeated by repeaters 152A to 152D and the EMM packet of the second satellite management company are transmitted from the site 200 of the second satellite management company and are repeated by the first satellite operation company's repeaters 252B to 252E are mixed in EMM mixers 153Ato 153D. In the site of the second satellite management company, the EMM packet of the second satellite management company that is repeated by a repeater 252A and the EMM packet of the first satellite management company that is transmitted from the second satellite management company by way of an EMM repeater 153 from the site 100A of the first satellite management company are mixed in an EMM mixer 253. Thus, even if both satellites are received, reception contract information can surely be received.

れる。When digital satellite broadcasting is received, a dedicated IRD for decoding a video signal and an audio signal is used.
(Integrated Reciever / Decoder) is required. When some digital satellite broadcasting services appeared,
It is expected that the number of viewers who want to enjoy digital satellite broadcasting by subscribing to a plurality of digital satellite broadcasting services will increase. However, it is inconvenient to purchase a new IRD to subscribe to a different digital satellite broadcasting service. Therefore, it is desired that the IRD can be commonly used in each digital satellite broadcasting service.

When a contract is made with a satellite operating company that manages satellite broadcasting, the reception contract information is transmitted as an EMM packet from the site of the satellite operating company and transmitted via a satellite managed by the satellite operating company. Come. On the receiving side,
The ID of the transmitted EMM packet is compared with the ID of the attached IC card, and if the EMM packet is addressed to itself, it is fetched. Therefore, when a digital satellite broadcast reception contract is concluded, the viewer needs to receive a signal from a satellite of the satellite operator of the digital satellite broadcast and receive an EMM packet addressed to itself.

なり得る。When the number of satellites to be received is one, the viewer always receives radio waves from the satellite, so that the EMM packet transmitted from the site of the satellite operating company can be reliably received. . However, if the IRD can be used in common for a plurality of digital satellite broadcasting services, when a viewer signs a contract with one satellite operating company, the viewer can use the satellite of another satellite operating company. Is received, the E-mail sent from the site of the satellite operating company despite signing a reception contract
MM packets cannot be received. Therefore, despite the fact that the receiving contract has been made, the receiving contract information is not stored in the IC card, and there is a possibility that the viewer may be disadvantaged such as being unable to receive the broadcast of the contracted channel, which may be a serious problem.
