KR960028314A - High speed search apparatus for broadcasting channel of 2-tuner television - Google Patents

Abstract

The present invention relates to a fast channel search apparatus for a two-tuner television, comprising: an IF module having a two-tuner and performing an intermediate frequency conversion process on a broadcast signal of a channel tuned by at least one tuner, the IF module comprising: A television comprising video / audio reproducing means for reproducing video and audio of a processed broadcast signal, comprising: function setting means for setting a high-speed search mode of a channel by said two tuners, and high speed by said function setting means; Control means for controlling to search the channel for each frequency band for the first and second tuners of the second tuner when the search mode is set, the channel data searched by the first and second tuner by the control step is stored And tuning data storage means for controlling the search of the VHF channel in the first tuner in the fast channel search mode of the two-tuner television. By the second tuner side is one such that the search and tuning of the large amount of channel greatly simplified as by a search of the UHF channels to be performed simultaneously.
