Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic channel search apparatus and method for television, comprising: tuner means 56 for tuning a broadcast channel in the VHF band and a UHF band, and audio signals of the broadcast signal tuned by the tuner means 56; Control panel 50 in a television comprising audio processing means (58, 60, 62, 64) for processing the video signal processing means (66, 68, 70, 72, 74) for processing the video signal of the broadcast signal When the automatic channel search mode is set by the automatic channel search mode setting button 50a of the channel and the band of the channel search target is determined by the band designation button 50b in the automatic channel search mode, the control unit 52 controls the control channel. The setting of the automatic channel mode and the band of the automatic channel search determined in the automatic channel search mode are included in the designated band while being displayed on the image display device 74 through the OSD processing unit 78 to display the broadcast signal. Automatically receive available channels Tuning is performed and the tuned result is stored in the channel data storage 76 so that a short time channel search by band designation is performed.
