Abstract

PURPOSE: A system for automatically detecting and displaying a disaster alarm is provided to supply information so as to deal with urgent disaster by forcibly turning on a television with a broadcast signal and a data signal. CONSTITUTION: A decoder and a control part detect an alarm broadcast start signal overlapped with a video signal under the state that standby power is turned on. The video signal is received to a television by wire or wireless. The decoder and the control part is embedded in the television or installed at the outside of the television. The decoder and the control part receives start data of a digital disaster alarm broadcast in a digital broadcast system. When the decoder and the control part detect the start signal or the start data, the control part checks whether main power of the television is turned on or off. This television is kept turned on if it is under a turn-on state and switched to the turn-on state if it is under a turn-off state.

Description

Disaster alert automatic detection and display system (tv) {omitted}

To turn on the TV, turn on the standby power (108) of the first tv, the second main power switch (109) using the remote control switch, etc.

The prior art is limited to turning on standby power for the first tv using relayed.

An object of the present invention relates to a method of turning on a TV main power supply with a second remote control switch or the like. The remote control switch has a feature of a toggle type switch that is pressed once and then pressed again.

By using this, in case of an emergency disaster or the like, the television is forcibly turned on by a broadcast signal or a data signal, and the information is provided to promptly respond.

In standby power 108 state

In analog tv, when only one tuner is provided, it is only available in standby power 108 mode.

When alarm broadcasting is performed on a specific channel, the control unit (m) 112 automatically selects a channel for alarm broadcasting upon receiving the main power source 109 off command, and then switches to standby power mode or monitors each channel when the power is turned off. If you have a system

When alarm broadcasting is performed on all broadcasting channels, alarm broadcasting can be viewed with only one tuner even when the main power source 109 of the TV is turned on.

In Figure 1

The control unit 112 checks whether the start signal / data is detected through the decoder (m) 111.

Control codes are input when start signal / data is detected.

The control unit (n) 112 compares whether the transmission time and the current time have a value within the tolerance range.

If it has a value within the tolerance range, the control unit (n) 112 checks whether information corresponding to the stored region, etc., exists among the information such as the receiving region.

If there is information that matches the information of the stored area, etc., the control unit (n) 112 turns on the main power source 109 of the tv so that power is supplied to each of the tv units in the standby mode.

Outputs the volume adjustment signal to increase the volume step by step while tuned to the input channel.⑥

It is changed or switched to the promised channel.⑦

Control unit (n) 112 for controlling the switching unit so that the broadcast signal is output to the AV.

The broadcast signal receiving unit 10 is a well-known tuner and IF processing unit which receives the tuned broadcast signal under the control of the control unit (n) 112 and separately outputs the composite video signal and the audio signal.

The video signal processor 20 processes and outputs the composite video signal separated by the broadcast signal receiver 10 as the video signal component RGB. The video signal processor 20 outputs the composite video signal to the Y / C separation unit; And a color signal processor for converting the separated Y / C signal into an RGB signal and a video signal mixer for mixing a caption processing signal including an OSD.

The image signal output unit 30 serves to display the image signal component RGB output from the image signal processing unit 20 and includes a CRT driver or a liquid crystal display.

The voice signal processor 40 processes and outputs the voice signal separated by the broadcast signal receiver 10 into a signal R / L that can be output through a speaker, and includes an amplifier at the output terminal. The amplification control is performed by the volume control signal output from 112 to amplify the audible sound. A voice signal output unit 50 is provided at the rear end of the voice signal processing unit 40 so that the voice signal separated by the voice signal processing unit 40 is converted into a speaker. It converts and outputs the signal (R / L) that can be output through.

The remote controller receiver 80 receives a signal transmitted from the remote controller and transmits the signal to the controller (n) 112.

The decoder (m) 111 separates the alarm broadcast signal from the composite video signal output from the broadcast signal receiving unit 10, divides the alarm broadcast signal into alarm broadcast information, and outputs it to the control unit (n) 112. Alternatively, the decoder (m) 111 generates a caption processing signal according to the separated caption information and outputs it to the image signal processor 20.

The control unit (n) 112 controls the overall operation by the control program data stored in the storage unit 90.

For example, the control unit (n) 112 detects the same area information as the start information and the area information stored in the storage unit 90 among the separated alarm broadcast control information, and when the transmission time within the error range is detected, Turn on the main power 109 of the tv or switch to the tv viewing mode, and control tv to output a predetermined broadcast signal, where the current time information is an optional function to ignore the start information comparison. In this case, even if only the start signal / data is detected, the alarm broadcast mode may be switched.

Area codes, etc. can be input through the remote controller, and the area codes, etc., are stored in the storage unit 90 of the control unit (n) 112 and compared with the reception area information. The user can save the necessary channel through the remote control.

In Fig. 3, the case where one tuner is provided and the VCR is watched.

A voice signal switching unit 41 for selecting and outputting one of a voice signal separated from a voice signal input to an external input device;

A video signal switching unit 21 for selectively outputting one of a video signal and a composite video signal input to an external input device is added.

The video signal switching unit 21 selects one of the video signal input through the video input terminal and the composite video signal output from the broadcast signal receiver 10 according to the switching signal output from the control unit (n) 112.

The voice signal switching unit 41 selectively outputs one of an external voice signal input through the voice input terminal and a voice signal output from the broadcast signal receiver 10 under the control of the control unit (n) 112.

If the alarm broadcast is transmitted while watching a video played from an external input device such as a VCR, the main power source 109 of the TV is turned on to control the TV broadcast mode so that the alarm broadcast is displayed. You will encounter alarm broadcasting.

In Fig. 4, when there are two tuners

The broadcast signal receivers 10 and 15 are further added, and the video signal switch 230 and 240 and the voice signal switch 210 and 220 are further added. The video signal switching unit 230 and 240 may be integrated into one. The voice signal switching unit 210 or 220 may also be integrated into one switching unit.

The video signal receiver 2 (15) includes a tuner and an IF processor exclusively for alarm broadcasting, and is tuned and controlled by the controller (n) 112. The video signal receiver 2 (15) is input or designated to receive only alarm broadcasting. The received broadcast signal is separated into an audio signal and a composite video signal, and output to the audio first switching unit 210, the decoder (m) 111, and the video first switching unit 240, respectively. The voice first switching unit 210 selects and outputs one of a voice signal input from an external input device through the voice input terminal and a voice signal output from the broadcast signal receiving unit 2 (15) under the control of the control unit (n) 112. In the same manner, one of the video signals is selected and signal-processed by the video signal processor 20 and output.

The transmission of digital broadcasting is composed of a data stream. The data is coded by a certain unit (e.g., a packet), and the data stream is divided and transmitted by the code.

Example: ① Data ② Audio ③ Auxiliary signal (alarm broadcasting signal) ① Video ② Audio ③ Auxiliary signal (alarm broadcasting signal) of channel r ① Video ② Audio ③ Auxiliary signal (alarm broadcasting signal) ① Video ② Audio ③ auxiliary signal (alarm broadcasting signal).

To the back,

Even when watching the channel r, if the disaster alarm is broadcasted in other channels, the broadcasting station can change the channel code from r to s to transmit the alarm broadcast. In other words, there is an effect of changing the channel when necessary by the broadcasting station. Similar to the analog case except for the characteristics of digital broadcasting.

In FIG. 5, the broadcast signal receiver 300 includes a tuner and an IF processor. In the receiver 300, the tuner inputs a digital broadcast signal received through an antenna and, according to the control of the controller (n) 112, The channel processor 310 tunes a channel, converts the IF signal according to the tune into a baseband signal, and outputs the baseband signal.

The channel processor 310 reproduces the data bit stream by channel decoding the baseband signal output from the IF processor.

The TS decoder (m) 111 functions to separately output audio data, video data, and auxiliary data from the data bit stream reproduced by the channel processing unit 310. The audio data is stored in the MPEG-2 audio decoder 360. After decoding according to the standard, the amplifier 370 is amplified and output.

The image data is decoded according to the standard in the MPEG2 image decoder 330 and the OSG (on screen graphic) mixer 340 is merged with the OSG data generated under the control of the control unit (n) 112 and processed. The OSG data is data for the controller (n) 112 to display various information on the screen in graphic or text.

The auxiliary data separated from the TS decoder (m) 111 is applied to the control unit (n) 112. Such auxiliary data may include control information codes for re-alarm broadcasting. Control unit (n) 112 Controls the operation of the TV, turn on the TV main power when the start information / area information / transmission time information, etc. of the alarm broadcast control information is detected or by switching the operation mode to the TV watching mode, the broadcast signal of the alarm broadcast is AV output The storage unit 90 serves to temporarily store the control program data and data generated during the system control operation.

In the standby power state, when the alarm broadcast start data is detected through the TS decoder (m) 111, the control unit (n) 112 checks whether the time information / region information is matched, and if it matches, the control unit (n). 112 turns on the main power source 109 of the tv so that power is supplied to each unit of the standby power source 108, and outputs a volume control signal so that the volume level is increased.

The alarm broadcast subtitle data information separated from the TS decoder (m) 111 and input to the control unit (n) 112 is output in the form of OSG data, input to the OSG mixer 340, and output to the image output unit 350. Can be.

6, digital tv (2 tuners)

When the alarm broadcasting start data is detected through the receiver 2 (410), and the time information matches, and the region information matches, the control unit (n) 112 turns on the main power of the tv, and the broadcast signal receiver 2 (410). The MPEG audio decoder and the video decoders 360 and 330 are controlled to output an AV signal through the AV signal. The caption data of the alarm broadcast received through the broadcast signal receiver 2 410 is mixed with the broadcast signal by the OSG mixer 340. And output.

While watching the video input from the external input, you can switch to the TV viewing mode and output the alarm broadcast in the same way as in the analogue.

Several cases are described by way of example.

Almost all of the components that make up the receiver are already embedded in digital or color televisions, which can be implemented by software changes, so they are less expensive and simpler to implement.
