Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic search channel signal level display apparatus of a television, comprising: a control panel (10) for setting an automatic channel search mode for a channel selectable by the tuner (18), and automatically controlled from the control panel (10). When the channel search mode is set, the control unit 12 controls the control of the search process for the search target channel and the level indication of the signal strength of the searched channel, and the tuner 18 under the control of the control unit 12. The channel data storage unit 14 and the channel data storage unit 14, which are stored in the channel selection data applied to the automatic channel search performed by the control unit 12 and the automatic channel search result, are controlled by the tuner 18. Synchronization signal detection unit 36 for detecting the synchronization signal and the signal level of the corresponding channel, display for automatic channel search mode and search channel specified by the control panel 10, automatic channel search result and signal level display And an OSD processing unit 34 for generating surface display data, wherein the display of the signal level performed under the control of the control unit 12 is strong, medium, or weak with respect to the signal strength of the channel searched by the channel search. It is displayed as or different colors based on the signal strength of the corresponding channel number.
