Abstract

A set-top box and a TV for automatically detecting and displaying disaster alarm are provided to compulsorily turn on a main power of the TV using a broadcasting signal or a data signal when emergency disaster is generated and quickly offer disaster information. A broadcasting signal receiving unit(10) receives a tuned broadcasting signal, and divides the received broadcasting signal into a complex video signal and an audio signal. An audio signal processing unit(40) processes the divided audio signal as an audio signal capable of being outputted through a speaker. A video signal processing unit(20) processes the divided complex video signal as a video signal capable of being displayed on a display device. A decoder(111) separates an alarm broadcasting signal from the complex video signal, divides the alarm broadcasting signal into control information, and outputs control information. A storing unit(113) stores alarm broadcasting start information and region information from separated information. If alarm broadcasting start information and region information are detected, a control unit(112) turns on a main power(109) of a TV, converts a current mode into a TV watching mode, and controls switching units to output the broadcasting signal as audio and video signals.

Description

Disaster alarm automatic detection and display system (settop box / TV) {settop box / tv}

To turn on the TV, turn on the standby power (108) of the first tv, the second main power (109) of the TV with a remote control switch or the like.

The prior art is limited to turning on the standby power 108 of the first tv using relays.

An object of the present invention relates to a method of turning on the main power supply 109 of a tv 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 turned off once again.

By using this, when an emergency disaster or the like occurs, the main power source 109 of the TV is forcibly turned on by a broadcast signal or a data signal, and the information is provided to promptly respond.

A. stb (settop box) for receiving tv, has almost same tv parts

B. As a stb having almost as-is-tv parts, in order to turn on / off the main power supply 109 of the tv, a sensor 104 for detecting the state of the tv main power supply 109 (power detecter) Should be internal and external to stb.

A. stb for receiving TV has almost as it is a tv circuit, the alarm broadcasting reception method is as follows.

In analog stb, when only one tuner is provided, the alarm broadcast can be viewed in all cases only in the standby power source 108 mode.

When alarm broadcast is made through specific channel

When the control unit (n) 112 receives a power-off command, it selects a channel that transmits an alarm broadcast, and then switches to the standby power 108 mode or monitors each channel when the power is off.

When alarm broadcasting is provided in all broadcasting channels, alarm broadcasting can be viewed using only one channel even when the TV is on.

In Figure 1

Through the decoder (m) 111 and the control unit (n) 112, it is checked whether a start signal / data is detected.

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 the value is within the allowable error range, the control unit (n) 112 and the storage unit 113 check whether information corresponding to the stored region, etc., exists in the information such as the receiving region.

If there is matching information, the control unit (n) 112 outputs a signal such that the main power source 109 is supplied to the tv which is the standby power source 108 mode.

The control unit (n) 112 outputs a volume adjustment signal so that the volume is adjusted upward in stages.

The controller 112 outputs a signal to be switched or switched to a contracted channel.

Adjust the volume up or subtitles.⑧

In case of analog tv broadcasting system

Alarm broadcast control codes and data are encoded in the video signal with an encoder to be superimposed on the vertical blanking interval (VBI), or in the case of digital tv broadcasting, the encoded control codes and data are inserted into a data stream of the digital signal. (Overlapping) to propagate.

The control unit (n) 112 controls the switching units to output the broadcast signal.

The broadcast signal receiver 10 includes a well-known tuner and an IF processor for receiving the tuned broadcast signal under the control of the controller (n) 112 and separately outputting 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 and amplified by 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 speaker is separated from the voice signal processing unit 40 by the speaker. It converts and outputs the output signal through R / L.

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 113.

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 113 among the separated alarm broadcasting 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 to control tv to output a predetermined broadcast signal, where the current time information is an optional function to ignore the starting information comparison. In this case, even if only the start signal / data is detected, the alarm broadcast mode can be switched.

The region code may be inputted through a remote controller or the like, and the region code may be stored in the storage unit 113 by the control unit (n) 112 and compared with the reception region information. Therefore, the user can save the necessary channel through the remote controller.

The transmission of digital broadcasting is composed of a data stream. The data is coded in a predetermined 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, the channel has the effect of changing the channel if necessary. Similar to analog, except for the characteristics of digital broadcasting.

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 under the control of the controller n, 112, the channel processor 310. Channel), and converts the IF signal according to the channel into a baseband signal and outputs it.

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 string reproduced by the channel processing unit 310. The audio data is the MPEG2 audio start signal 360. After decoding according to the standard in the amplifier 370 is amplified and output.

The image data is decoded according to the standard in the MPEG2 image start signal 330, and in the osg (on screen graphic) mixer 340, is combined with the osg data generated under the control of the control unit (n) 112 and image processed. The OSG data is then output on the screen through the image output unit 350. The OSG data is data for the control unit (n) 112 to display various types of information on the screen as a graphic or text.

The auxiliary data separated by the TS decoder (m) 111 is applied to the control unit (n) 112. Such auxiliary data may include control information codes for alarm broadcasting. When the operation of the stb system is controlled and the main broadcasting unit 109 is turned on when detecting start information / region information / transmission time information among alarm broadcasting control information, or the operation mode is switched to the TV viewing mode, the broadcasting signal of the alarm broadcasting is The system controls the system to output AV. The storage unit 113 temporarily stores the control program data and data generated during the system control operation.

In the standby power source 108, when the alarm broadcasting start data is detected through the TS decoder (m) 111, the control unit (n) 112 checks whether or not the time information / region information matches. n) 112 turns on the main power source 109 of the tv so that power is supplied to each system in the standby state, and outputs a volume control signal so that the volume level is raised.

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.
