Abstract

본 발명은 시청자가 대기전원상태에서 전원 온했을 때. 이것을 시청한 채널중 가장 오래 시청한 채널을 선국하도록 된 텔레비전의 튜너를 제어하여 채널을 선국하기 위해 필요로 하는 채널데이터가 저장되는 제1저장수단, 소정의 시간데이터를 공급하기 위한 타이머수단; 상기 제1저장수단에 저장된 각 채널들에 대응하여 시간데이터를 저장하기 위한 제2저장수단, 튜너의 채널변경시 상기 타이머가 계수한 시간데이터를 독출함과 동시에 타이머를 리셋시키며, 제2저장수단에 저장된 해당 채널의 시간데이터를 독출하고, 그 독출된 시간데이터와 상기 타이머수단으로부터 독출한 시간데이터를 합하여 그 결과를 다시 제2저장수단에 저장하는 연산수단, 및 텔레비전의 전원은 신호발생시 상기 제2저장수단에 저장된 각 채널들의 시간데이터를 비교하며, 이 비교결과 가장 큰 시간값을 갖는 채널을 독출시키고, 이 독출된 채널에 해당되는 채널선국용 데이터를 상기 제1저장수단으로 독출하여 이 독출된 채널선국용 데이터를 근거로 튜너를 제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.When the viewer is powered on in the standby power state. First storage means for storing channel data necessary for tuning a channel by controlling a tuner of a television that is tuned to a channel that has been watched for the longest of the channels watched, and timer means for supplying predetermined time data; Second storage means for storing time data corresponding to each of the channels stored in the first storage means, reading the time data counted by the timer at the time of changing the channel of the tuner, and resetting the timer; Arithmetic means for reading the time data of the corresponding channel stored in the apparatus, adding the read time data and the time data read out from the timer means, and storing the result back in the second storage means; (2) Compare the time data of each channel stored in the storage means, and read the channel having the largest time value as a result of the comparison, and read out the channel selection data corresponding to the read channel to the first storage means. And control means for controlling the tuner based on the data for channel selection.

Claims

A channel control apparatus for a television configured to tune a predetermined channel by controlling a tuner, the channel control apparatus comprising: first storage means for storing channel data necessary for controlling a tuner of the television to tune a channel; Timer means for supplying predetermined time data; Second storage means for storing time data corresponding to each channel stored in the first storage means; When changing the channel of the tuner, the timer reads the time data counted by the timer and resets the timer, reads the time data of the corresponding channel stored in the second storage means, and reads the read time data from the timer means. Computing means for adding up the data and storing the result back into the second storage means; And a power-on signal generator of the television to compare the time data of each channel stored in the second storage means, and to read out the channel having the largest time value based on the comparison result, and to select channel selection data corresponding to the read channel. And control means for reading from the first storage means and controlling the tuner based on the read channel selection data.
