Enhanced TV system using transmitted error signals

摘要

A television system for generating video signals for reception by a receiver having adaptive processing circuitry susceptible of errors includes circuitry for emulating portions of the receiver and detecting the occurrences of such errors. A signal representing the occurrences of the errors is generated and combined with the transmitted video signal. At the receiver the error signal is separated from the video signal and utilized by the adaptive processing circuitry to ameliorate the effects of such errors.
