KR970014237A - Automatic Channel Tuning Device and Method of Television - Google Patents

Abstract

The present invention relates to an automatic channel tuning method of a television, comprising: key input means for inputting the channel up / down tuning station in a television capable of direct channel selection or channel up / down tuning; When the channel up / down channel selection is input by the microcom means for controlling the channel search / channel up / down channel selection by determining whether or not the memory is stored by the preceding channel search, the memory channel searched under the control of the microcom means. The stored channel memory means, a synchronization signal detecting means for detecting a video synchronization signal for determining whether to view a channel to be searched for when searching for a channel executed by the control of the microcomputer means, and the searched memory channel. OSD generation means for executing the screen display, and if the channel up / down station is input by the key input means By determining the existence of the memory channel, if the memory channel is not present, the channel search is performed sequentially for the entire channel, and only the channel in which the video synchronization signal is detected among the channels targeted for the channel search is the memory channel. Judgment is to be remembered.
