TH9891A - Television system with very sharp parts, the type used to send wrong signals. - Google Patents

Abstract

Television systems for generating video signals to be received by receivers with a faulty-sensitive modified signal processing circuit, as well as circuits for making different parts of the receiver. To simulate and detect the occurrence of such an error signal, a representative signal is generated and Combined with the transmitted video signal The error signal at the receiver is isolated from the image signal and is used by the modified signal processing circuit. To help correct such error signals

Claims (1)

1. a machine for generating a television signal so that it is received by a receiver with a signal processing circuit adapted to respond It can vary depending on the nature of the detected signal and is sensitive to the detection error of such characteristics. The unit consists of a signal source. The encoding path is connected to that source for Generates an encrypted video signal for transmission. The decryption path is connected to the aforementioned encryption path. This includes a method for enabling the aforementioned modified signal processing circuit to mimic the faulty signal.
