Abstract

VTR이나 TV에서 방송수신시 방송지역을 자동판별해서 그지역에 해당되는 반송파주파수를 송출해서 선국을 빠르고 정확하게 수행하도록 한 방식이 기술되는바, 이는 사용자가 채널선국을 소정횟수 하였을 경우 각채널선국에 필요한 시간(T)을 계산하여 방송지역을 판별하고, 상기의 지역판별후 채널선국시 방송지역에 해당되는 중심주파수(fo)를 송출해서 방송을 선국토록하는 단계로 이루어진다.When a VTR or TV receives a broadcast, a method of automatically discriminating a broadcasting region and transmitting a carrier frequency corresponding to the region is performed so that tuning can be performed quickly and accurately. After calculating the required time T, the broadcasting region is determined, and the center frequency fo corresponding to the broadcasting region at the time of channel selection is transmitted and the broadcasting is tuned.

방송지역 자동 판별방식Broadcast area automatic discrimination method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 방송지역 자동 판별기능을 갖는 칼라 텔레비젼의 개략적 블럭도,1 is a schematic block diagram of a color television having a broadcasting area automatic discrimination function according to the present invention;

제3도는 주파수에 대한 자동주파수 선국전압을 도시한 그래프,3 is a graph showing automatic frequency tuning voltage versus frequency;

제4도는 방송지역별 중심주파수의 차이를 비교한 도표이다.4 is a chart comparing the differences in the center frequencies of broadcasting regions.

Claims (3)

사용자가 채널선국을 소정횟수 하였을 경우 각채널 선국에 필요한 시간(T)을 계산하여 방송지역을 판별하는 단계와, 상기의 방송지역 판별후 채널선국시 판별된 방송지역에 해당되는 중심주파수(fo)를 송출하여 방송을 선국토록하는 단계로 이루어진 것을 특징으로 하는 방송지역 자동 판별방식.Determining a broadcasting area by calculating a time (T) required for each channel selecting when a user selects a predetermined number of channels, and a center frequency (fo) corresponding to the broadcasting area determined at the time of channel selection after determining the broadcasting area. Broadcasting area automatic discrimination method comprising the steps of transmitting the broadcast to tune. 제1항에 있어서, 상기의 방송지역 판별 단계는 자동채널 메모리 과정에서 상기의 소정횟수 채널선국을 해본 후에 각채널 선국에 필요한 시간(T)을 계산해서 방송지역을 판별토록 함을 특징으로하는 방송지역 자동 판별방식.The broadcasting zone determining step of claim 1, wherein the broadcasting region determining step determines a broadcasting region by calculating a time (T) required for each channel selecting after performing the predetermined number of channel selections in the automatic channel memory process. Local automatic discrimination method. 제1항에 있어서, 상기의 방송지역 판별 단계는 지역판단모드에 해당되는 입력 명령을 사용하여 사용자가 키이 또는 리모콘으로 지역판단모드의 명령을 줄경우 자동으로 소정갯수의 채널을 선구해본뒤 각채널선국에 필요한 시간(T)을 산출하여 방송 지역을 판단함을 특징으로하는 방송지역 자동 판별방식.The method of claim 1, wherein the step of determining the broadcasting region automatically establishes a predetermined number of channels when a user commands a region determination mode using a key or a remote control using an input command corresponding to the region determination mode. A broadcasting area automatic discrimination method characterized in that the broadcasting area is determined by calculating the time (T) required for tuning. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
