Abstract

본 발명은 영상신호 처리장치의 채널 자동탐색방법에 관한 것으로서, 간단한 조작으로 전채널의 방송내용을 확인한 후, 다시 현재채널로 복귀하도록 하기 위하여, 방송신호를 튜닝하는 튜너와, 채널데이타를 저장하는 메모리와, 시간정보를 출력하는 타이머, 및 전술한 각 구성부를 제어하는 마이크로컴퓨터를 구비하는영상신호처리장치의 채널 자동탐색방법에 있어서; 상기 메모리에 저장된 전채널데이타를 검출하고, 현재채널을 상기메모리에 저장하며, 상기 메모리로부터 검출된 전채널데이타에 따라 상기 튜너를 제어하여 전채널의 방송신호를 튜닝하고, 상기 타이머에서 카운팅된 시간을 검출하여 소정시간이 경과하면 상기 메모리에 저장된 현재채널데이타를 검출한 후 , 상기 메모리로부터 검출된 현재채널데이타에 따라 상기 튜너를 제어하여 현재채널의 방송신호를 튜닝하는 과정을 수행하도록 하였다.The present invention relates to a channel automatic search method of an image signal processing apparatus. The present invention relates to a tuner for tuning a broadcast signal and storing channel data in order to return to the current channel after checking the broadcast contents of all channels with a simple operation. A channel automatic search method of a video signal processing apparatus having a memory, a timer for outputting time information, and a microcomputer for controlling each of the above-mentioned components; Detects all channel data stored in the memory, stores the current channel in the memory, controls the tuner according to all channel data detected from the memory, tunes the broadcast signal of all channels, and counts the time counted by the timer. When the predetermined time elapses, the controller detects the current channel data stored in the memory and controls the tuner according to the current channel data detected from the memory to tune the broadcast signal of the current channel.

Claims

A channel auto-detection method of a video signal processing apparatus comprising a tuner for tuning a broadcast signal, a memory for storing channel data, a timer for outputting time information, and a microcomputer for controlling the above-described components; Detects all channel data stored in the memory, stores the current channel in the memory, controls the tuner according to all channel data detected from the memory, tunes the broadcast signal of all channels, and counts the time counted by the timer. When the predetermined time elapses, the controller detects the current channel data stored in the memory and controls the tuner according to the current channel data detected from the memory to tune the broadcast signal of the current channel. Channel auto search method of processing equipment

The method of claim 1, further comprising: detecting all channel data stored in the memory when a channel automatic search function is selected; Initiating counting after resetting the timer; A third step of storing the contention channel in the memory and tuning the broadcast signal of all channels by controlling the tuner according to all channel data detected in the first step; A fourth step of checking whether a counting time is equal to a reference time by checking a time counted by the timer; And if it is determined that the counting time is equal to the reference time, after detecting the current channel data from the memory, performing a fifth step of tuning the broadcast signal of the current channel by controlling the tuner according to the detected current channel data. Automatic channel search method of image signal processing device
