Abstract: A descramble section extracts required information for descrambling transmitted together with TV signals and converts scrambled signals to ordinary TV signals in response to input control signals. A microcomputer system has a function of processing view-contract management using a required information for descrambling and applies the control signals to the descramble section based on a result of the viewer-contract management processing, when an IC card is not connected. On the other hand, when IC card is connected, the microcomputer system gives the required information for descrambling to the IC card and gives control signals from the IC card to the descramble section without processing the viewer-control management. The IC card performs the viewer-contract management processing using the necessary information for descrambling, and gives control signals to the microcomputer system based on the result of the viewer-contract management processing.

Abstract: In a repeating device for sending chargeable satellite broadcasting received through a BS antenna to a connected cable, a scrambled video signal and an audio signal are separated from each other by a separation part from a satellite broadcast signal. Relevant information packets multiplexed upon the audio signal are separated from each other by a separating part, and common information packets of the relevant information packets are separated from each other by another separation part. Common information packets which are successively sent five times are judged in majority by a majority judgement part. Packets having errors corrected by an error correction part are temporarily stored in a buffer memory. The stored packets are read out three times by a thrice successive sending part wherein the stored packets are successively sent fewer times than the number of times the packets are sent from from an atmospheric transmission system.
