KR960043818A - Multi-channel monitoring method and device by time division method - Google Patents

Abstract

The present invention relates to a multi-channel monitoring method and apparatus by a time division method, and in particular, to monitor the radio frequency of a plurality of channels received from the air with one television receiver, one of the contents of a specific channel through two radio frequency inputs. And another radio frequency input relates to a method and apparatus for continuously monitoring the contents of each channel sequentially at a time interval set to monitor the contents of the monitoring of multiple channels simultaneously when necessary.

That is, one of the two screen generators broadcasts the broadcast program of a specific channel, and the other screen generator can monitor the broadcast contents of the broadcast program of multiple channels at the same time if necessary, and broadcast each channel at a set time interval. By continuously searching the contents in order to improve the reliability of the television receiver and the user's convenience.
