〔発明の目的〕
（産業上の利用分野）
本発明は、特に有料の衛星放送を受信する衛星放送受信
システムに関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention particularly relates to a satellite broadcast receiving system for receiving paid satellite broadcasts.
（従来の技術）
近い将来、実用化される放送衛星による有料放送では、
契約者以外の者による視聴を確実に防止する必要がある

きず、番組の視聴が不可能となるのである。(Conventional technology) In pay broadcasting using broadcasting satellites that will be put into practical use in the near future,
It is necessary to reliably prevent viewing by anyone other than the subscriber. For this reason, the broadcasting provider scrambles the video and audio signals before transmitting them, and the subscriber's receiving device uses the assigned ID code as the ID in the contract information superimposed on the broadcast radio waves. It is thought that the video signal and the audio signal are descrambled based on the contract information obtained by matching the code so that they can be viewed. Therefore, non-subscribers are unable to obtain the contract information necessary for descrambling processing from the airwaves, making it impossible for them to view the program.

聴できず、自分の受信装置を持ち込む必要があるといっ
た事態が生じる。(Problem to be solved by the invention) By the way, ID codes should originally be allocated to the subscriber, but in reality, the ID code is allocated to the receiving device owned by the subscriber. It is expected that this will be the case. Therefore, even if you are a subscriber, if you do not have your own receiving device to which an ID code has been assigned, you will not be able to view the program you subscribed to. Specifically, for example, if a subscriber wants to watch a program that he or she has subscribed to at another subscriber's house, the program cannot be viewed on the receiving device at the other subscriber's house, and the program must be brought in with the user's own receiving device. Situations such as this occur.
本発明は上記に鑑みてなされたもので、その目的として
は、自分あるいは他人の受信装置に関係なく受信装置が
あれば契約者による番組の視聴ができるようにした衛星
放送受信システムを提供することにある。The present invention has been made in view of the above, and an object of the present invention is to provide a satellite broadcast receiving system that allows a subscriber to view a program as long as he or she has a receiving device, regardless of whether the subscriber has a receiving device or someone else's receiving device. It is in.

いる。(Function) The satellite broadcast receiving system according to the present invention has been developed with attention paid to the practical use of portable electronic devices such as IC cards in recent years, and receives portable electronic devices owned by subscribers. When connected to the device, the receiving device uses the contract information necessary for descrambling processing obtained by comparing the subscriber identification information stored in the portable electronic device with the contract information included in the satellite broadcast. By controlling the operation of the descrambling means provided in the receiving device, the electronic device enables viewing of the contracted program.
（実施例） 以下、図面を用いて本発明の詳細な説明する。(Example) Hereinafter, the present invention will be explained in detail using the drawings.
第１図は本発明の一実施例に係る衛星放送受信システム
の構成を示す図である。同図において、１は携帯可能電
子機器を構成するＩＣカード、３は受信装置である。FIG. 1 is a diagram showing the configuration of a satellite broadcast receiving system according to an embodiment of the present invention. In the figure, 1 is an IC card forming a portable electronic device, and 3 is a receiving device.

。The IC card 1 includes an ID memory 5 in which an identification code unique to the owner is stored in advance, a contract information memory 7 that stores contract information necessary for descrambling processing of satellite broadcasting, and an ID memory 5 in which an identification code unique to the owner is stored in advance;
The configuration includes a microcomputer 11 having a function of controlling the overall operation of the C card 1 and at least controlling the operation of a descrambler 9 in a receiving device 3, which will be described later.

比較部１７と、衛星放送信号をデスクランブル処理する
デスクランブル部９とを有する構成である。The receiving device 3 includes an ID reading section 13 that reads an ID code from the ID memory 5 of the connected IC card 1, an ID storage memory 15 that stores the read ID code, and an ID code included in the read ID code and broadcast radio waves. An ID that stores contract information necessary for descrambling processing in the contract information memory 7 of the IC card 1 based on the comparison result with the contract information.
The configuration includes a comparison section 17 and a descrambling section 9 that descrambles a satellite broadcast signal.
次に、本実施例の作用を説明する。Next, the operation of this embodiment will be explained.
受信契約については、例えばＩＣカードを既に所有して
いれば、ＩＣカード１の所有者識別のために予め設定さ
れているＩＤコードを用いて事前に契約が行なわれてい
るものとする。Regarding the reception contract, it is assumed that, for example, if the user already owns an IC card, the contract has been made in advance using an ID code set in advance to identify the owner of the IC card 1.
そして、このＩＣカード１の所有者、すなわち契約者が
契約した番組を視聴するべく受信装置３（自分のものあ

の契約情報メモリ７に記憶させる。Then, when the owner of this IC card 1, that is, the subscriber, connects the IC card 1 to the receiving device 3 (regardless of whether it is his or her own or someone else's) in order to watch the contracted program, the ID of the receiving device i3 is read. The unit 13 is the ID memory 5
The ID code is read from the ID code and stored in the ID storage memory 15. The ID comparison unit 17 compares the subscriber's ID code included in the contract information sent from the broadcasting provider with the ID code stored in the ID storage memory 15, and if the two match, is determined to be a valid subscriber and sends the contract information necessary for descrambling processing to IC card 1.
is stored in the contract information memory 7 of.
したがって、ＩＤコードが一致しない場合には、正当な
受信契約者と判断されず、デスクランブルに必要な契約
情報が記憶されず、番組を視聴することができない。Therefore, if the ID codes do not match, the user is not determined to be a valid reception subscriber, contract information necessary for descrambling is not stored, and the program cannot be viewed.
ＩＣカード１は、契約情報メモリ１５に記憶された契約
情報に基づき、デスクランブル部９に対しデスクランブ
ル処理するか否か等の所定の制御を行うことで、契約し
た番組の視聴を可能とする。Based on the contract information stored in the contract information memory 15, the IC card 1 performs predetermined control on the descrambling unit 9, such as whether or not to perform descrambling processing, thereby making it possible to view the contracted program. .
したがって、本実施例によれば、契約者としてはＩＣカ
ードのみを所有していれば契約した番組の視聴が可能に
なるので、例えばある契約者が他の契約者宅で、自分が
契約した番組を視聴したい時など、ＩＣカードのみを持

リティ性を保持することができる。Therefore, according to this embodiment, if a subscriber owns only an IC card, he or she can watch a contracted program. When you want to watch a TV program, you can simply bring your IC card and connect it to a receiving device owned by another subscriber, which increases versatility. In addition, since the microcomputer is located in the IC card, the system does not operate when the C card is not installed, so high security can be maintained.

具合はないのである。Note that IC cards may be lent to subscribers by the broadcasting provider in accordance with the contract, or in the near future, IC cards may be
Since it is expected that C cards will become popular at the individual level, an IC card owned by the subscriber may be used. That is, in either case, the ID code for viewing the program is assigned to the subscriber, not to the receiving device, so there is no problem as described above.
また、本実施例では、携帯可能電子機器としてＩＣカー
ドを用いた場合について説明したが、これに限定されな
いことはもちろんである。Further, in this embodiment, a case has been described in which an IC card is used as the portable electronic device, but it is needless to say that the present invention is not limited to this.
以上説明したように本発明によれば、契約者の所有する

ことができる。As explained above, according to the present invention, when a portable electronic device owned by a subscriber is connected to a receiving device, the receiving device receives identification information of the subscriber stored in advance in the portable electronic device and information included in satellite broadcasting. Based on the contract information necessary for descrambling processing obtained by comparison with the contract information provided by the contract, the portable electronic device controls the operation of the descrambling means installed in the receiving device, thereby realizing the viewing of the contracted program. Therefore, regardless of whether the subscriber has a receiving device or someone else's receiving device, the program can be viewed by the subscriber.
