摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] 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 an audio signal of a broadcast signal tuned by the tuner means 56; A television comprising audio processing means (58, 60, 62, 64) for processing a video signal and video processing means (66, 68, 70, 72, 74) for processing a video signal of the broadcast signal. The control panel 50 for setting the automatic channel search mode for the channel and switching the broadcast channel in the automatic channel search mode, and the search target in response to the mode setting from the control panel 50 and the band switching of the broadcast channel. Control means 52 for controlling the automatic search of a channel included in the band of RTI ID = 0.0 , / RTI Channel search results for The channel data storage means 76 and the tuner means 56 detects a synchronization signal with respect to the broadcast signal of the channel provided by the control means 52 to provide a criterion as a channel capable of viewing the broadcast signal OSD, which is designated by the synchronization signal detecting means 80 and the control panel 50 to generate an automatic channel search mode executed under the control of the control means 52 and screen display data relating to the band of the designated channel search target. And processing means (78), to set an automatic channel search mode for the television, to perform a search for a channel of a band initially designated in the automatic channel search mode, and during the search, band switching is performed. If so, it is characterized in that the automatic search for the channels included in the subsequent band.
