Scrambled television signal receiver system |
摘要 |
A television signal receiving system for use with a scrambled television signal or a standard television signal includes a recording and reproducing circuit which records and reproduces the received television signal and a monitor for displaying the received or reproduced television signal. A descrambling circuit descrambles the scrambled television signal either as received or reproduced to generate a descrambled television signal when a detector detects the existence of a scrambled television signal and generates a control signal in response thereto. A switch responds to the control signal and automatically supplies to the monitor either the descrambled television signal or the standard television signal according to the type of television signal being received or reproduced.
