Abstract

PURPOSE: A system for automatically detecting and displaying a disaster alarm boadcast is provided to compulsorily turn on a television using a start signal indicating the start of a disaster alarm broadcast. CONSTITUTION: A decoder and a microcomputer installed in a television or on a settop box detect a start signal indicating the start of a disaster alarm broadcast. If the start signal is detected, the decoder and a power detector(104) installed in the television or on the settop box judge whether the television is turned on or off. If the start signal is detected and the television is turned on, the decoder and the power detector maintain the current status of the television. If the start signal is detected and the television is turned off, the decoder and the power detector control the television to be turned on.

By means and method of detecting 103 the start signal 100 determined as the start of the broadcasting of the disaster warning set forth in the protocol by the decoder 101 and the micom 102 embedded in the TV or external to the stb.

시작 신호(100)가 decoder(101)와 micom(102)으로 검출(103)되면, tv에 내장 또는 stb에 외장된 micom(102)과 senser(powerdetector)(104) 로 tv의 on(105) 또는 off(106)상태를 파악하고,tv가 on(105) 상태이면 on(105)상태 그대로 두고, tv가 off(106) 상태 이면 on(105) 상태로 전환 (107)시키고When the start signal 100 is detected 103 by the decoder 101 and the micom 102, the micom 102 and senser (powerdetector) 104 embedded in the TV or external to the stb are turned on (105) of the TV or figure out the off (106) state, leave on (105) if tv is on (105), switch to on (105) if tv is off (106)

단,decoder(101)와 micom(102)은 같은 것을 사용할 수 있다.However, decoder 101 and micom 102 can use the same thing.

규약으로 정해진 재해경보방송 종료로 정한 종료신호(110)를 tv에 내장 또는 stb 외장된 decoder(101) 와 micom(102)으로 검출(103)하는 방식A method of detecting (103) the end signal (110) determined by the end of the disaster warning broadcasting prescribed by the protocol by the decoder (101) and the micom (102) built-in or stb mounted on a TV.

종료신호(110)가 decoder(101)와 micom(102)으로 검출(103)되면, tv등에 내장 또는 stb에 외장된 micom(102)과 senser(power detector)(104)로 tv의 on(105) 또는 off(106)상태를 파악하고, 재해경보방송 시작 이전에, tv가 on(105)상태 이었으면 on(105) 상태 그대로 두고, tv가 off(106) 상태 이었 으면-재해경보방송시작 으로 on(105)상태로 된 것을 다시- off(106) 상태 로 전환(117) 시키는 방법When the end signal 110 is detected 103 by the decoder 101 and the micom 102, the micom 102 and the senser power detector 104 embedded in the TV or the stb are turned on 105 of the TV. Or check the off (106) state, and before the start of the disaster alarm broadcast, leave the on (105) state if tv was on (105), if tv was off (106) state-start the disaster alarm broadcast on ( 105) How to switch from the state of the state back to the state of off (106) (117)

규약으로 정해진 재해경보방송 시작으로 정한 시작신호(100)와 재해경보방송 종료로 정한 종료신호(110)등을 주전파의 화상 신호에 중첩하여 송출 하여 tv등을 on/off등 으로 제어 하고 정보를 제공 하는 송출 방식Superimpose the start signal 100 determined as the start of the disaster warning broadcasting and the end signal 110 determined as the end of the disaster warning broadcasting according to the agreement and superimpose on the video signal of the main radio wave to control the TV light on / off and provide information. Transmission method to say

재해경보방송 시작과 종료시간 사이에 중대한 상황 변화가 있어서 변경 사실을 다시 알려야할 필요가 있을 시에는, 규약으로 정해진 재해경보방송 시작으로 정한 시작신호(100)등을 반복 송출 하여, 시작과 종료 사이에 상태변화 시에도 다시 경보를 접하게 하는 송출방법When there is a significant situation change between the start and the end of the disaster alarm broadcasting and needs to be notified of the change again, the start signal 100 determined as the start of the disaster alarm broadcasting prescribed by the protocol is repeatedly transmitted, and between the start and the end. Transmission method that encounters alarm again even when status changes

지역정보(우편번호,행자부 행정지역 code, 행정지역 명칭 등) 또는 집단정보(소방공무원,재해담당 공무원,주민등록번호,사회보장번호 등) 또는 장르별 정보(뉴스,뉴스 속보 등)를 시작신호(100)에 이어서 화상신호에 중첩하여 송출하여 조건에 따라 수신 집단을 선택 하는 방법Start signal (100) for local information (postal code, administrative department code, administrative region name, etc.) or group information (fire officials, disaster officials, resident registration numbers, social security numbers, etc.) or genre-specific information (news, breaking news, etc.) Subsequently, a method of selecting a reception group according to a condition by transmitting the image signal superimposed on it

data 방송같은 경우에도,규약으로 정해진 재해경보방송 시작으로 정한 시작신호(100)와 재해경보방송 종료로 정한 종료신호(110)등의 제어 신호로 규정된 신호를 송출하여 tv등을 on/off등 으로 제어 하고, 정보를 제공 하는 송출 방식Even in the case of data broadcasting, a signal specified by a control signal such as a start signal 100 determined by the start of the disaster alert broadcasting and an end signal 110 determined by the end of the disaster alert broadcasting, is transmitted by turning on / off the TV or the like. To control and provide information

data 방송이나 위성방송 같이 고객db(data base)(130)가 있는 경우에는, 그 db(130)를 조건에 따라 지역 또는 집단 또는 장르 별로 부분집합(131~n)으로 구성하고 ,그 부분집합(131~n)의 교집합 또는 합집합등의 방법으로, data(제어 신호 또는 정보)를 송출 하는 방법If there is a customer db (data base) 130, such as data broadcast or satellite broadcast, the db 130 is composed of subsets (131 to n) according to the conditions, groups, or genres according to the conditions, and the subset ( 131-n) Method of sending data (control signal or information) by intersection or union

재해경보방송 시작시에 자막(open,closed자막),data(문자,graphic,화상등),음성 등의 방법으로 정보를 제공하는 방식Method of providing information through the method of subtitle (open, closed subtitle), data (text, graphic, image, etc.), voice, etc. at the start of disaster alarm broadcasting

아나로그 방송에서는 tv등을 시청중 일때,다른 채널에서 재해경보 방송을 하는 경우등을 고려하면 튜너가 2개 있어야하나 디지털방송은 방송국 자체에서 코드 분할 방식으로,방송국 자체에서 지정된 채널로 선택 하여 재해경보방송을 시청 하게 하는 방식으로 1개의 demux만 필요 하다.In analog broadcasting, if you are watching tv, etc., you should have two tuners in consideration of disaster alarm broadcasting on other channels, but digital broadcasting should be selected by the channel division by code division method by the broadcasting station itself, Only one demux is needed to watch the alarm broadcast.

규약으로 정해진 재해경보방송 시작으로 정한 시작신호(100)송출시 현재 시각을 동시에 송출 하여,이 시각과 rtc의 시각이 오차 한계내에 있으면 재해경보방송 실행 시작으로 인식하여 tv등의 전원을 on 또는 off 등으로 제어하고 정보를 제공하는데, 오작동을 방지하는 송출 방식When the start signal 100 determined by the start of the disaster alarm broadcasting specified by the agreement is sent out at the same time, if the current time and the time of the rtc are within the error limits, it is recognized as the start of the disaster alarm broadcasting and the power of the TV is turned on or off. Controlling and providing information, etc., to prevent malfunction

수신기를 구성하는 거의 모든 부품이 디지털 tv(d-tv) 또는 디지털위성방송 stb에 이미 내장 되어 있어 소프트웨어 변경으로 구현 할 수 있는 것이 특징 이다.Almost all the components that make up the receiver are already embedded in digital tv (d-tv) or digital satellite broadcasting stb, and can be implemented by software change.

아나로그 tv로 tv를 시청중인 경우에,다른 채널로 주어지는 재해경보를 접하기 위해서는 한 개의 튜너가 더 필요 하고,아나로그 tv에는 rtc(real time clock) 또는 decoder 가 내장 되어 있는 model도 있고 없는 model도 있다. 없는 경우 에는 rtc(real time clock) 또는 decoder 을 내장 해야 한다.If you are watching tv on analog tv, you will need one more tuner to access disaster alerts from other channels, and analog tv has a model with built-in rtc (real time clock) or decoder. There is also. If not, an RTC (real time clock) or decoder must be built in.

디지털이나 아나로그,유선 또는 무선 으로 송출 되는 모든 신호가 같은방식으로 처리될수 있고 다른 기기에도 활용 가능 하다.All signals transmitted digitally, analog, wired or wireless can be processed in the same way and used in other devices.

수신기중 아나로그 형태의 stb의 한 예를 들면 다음과 같다.An example of analogue stb in the receiver is as follows.
