Description of Invention () The multimedia service through the CATV network is a service that asks the user for a certain fee according to the user's requirements. Therefore, the multimedia data transmitted at the input end is encrypted. The user center needs to set up a signal converter that can interpret this password in order to take advantage of this CATV service. That is to say, only provide services to users who apply for CATV services, and illegal use of other users should be promptly cut off. For this reason, a method of selectively cutting off a signal is proposed. U.S. Patent No. 6, 2 6 6, 4 8 1 discloses a selective access device for selectively controlling signal reception to a television receiving device. Selective access devices include: a way to receive video data that contains a key; a way to save the key to video memory; a way to identify authentication data from the memory; a way to control the transmission of data to an unauthenticated device; a record of the received program the way. Here, the key is decoded by the first key of the video program and the third key stored in the memory, and includes a first round key capable of interpreting the first key. That is, the input terminal sends the encrypted program to the user. The client needs to set a key decryption device built into the memory, so that the program sent by the input can be decrypted to watch the program. The representative # 方 问 装置 is a signal converter connected to a user's television and capable of interpreting program signals. Therefore, when a user applies for a CATV service, a CATV company installs a signal converter in the user's home that can receive CATV signals and can decrypt them.

Figure 6 shows the structure of a satellite broadcast system that sends satellite broadcast signals to users through a shunt. As shown in the figure, a broadcast signal transmitted through a satellite is received by a satellite receiving antenna 90. The received broadcast signal is converted into a low frequency signal by a low noise signal converter (LNB) 92. The low-frequency broadcast signals are respectively transmitted to the broadcast receiver 77 in the corresponding subscriber center through the splitter 80. At this time, the broadcast signal sent to the user center 10 is encrypted, so it needs to be decrypted by the broadcast receiver 77 so that the user can watch the television channel from the television 15.
