Description

Security control method by two way communication of TV

The present invention relates to a method for controlling security by two-way communication of a television, and more particularly, through a two-way communication between each television installed in a plurality of settlements, an intruder in one residence can be identified through a television in another residence. The present invention relates to a security control method using two-way communication of a television.

As is well known, in a television which receives a predetermined channel from among a plurality of television broadcasting signals transmitted from a plurality of television broadcasting stations, and performs video / audio playback through a CRT and a speaker, In addition to the video / audio playback function for a variety of functions to meet the various needs of the viewer is to be added.

The various functions included in the television include an on / off timer reservation function for turning on or off the television when the input time has elapsed by inputting a wake-up time and a sleep time. On-screen display (OSD) display function for visually confirming the function execution status or setting status of the overall function, and analog level of the video / audio signal (i.e., contrast and brightness in the case of a video signal) And video / audio analog level adjustment functions for adjusting the volume and high / low sound level in the case of an audio signal.

On the other hand, such a television is generally installed in the indoor center space of each home, and the video / audio information from the external playback device can be signaled and reproduced. In addition to the urgent need for the adoption of a security function to prevent the situation, it is necessary to make a more realistic security effect occurs.

Recently, when the predetermined security mode is set in the absence of the viewer, the operation of turning on / off the power of the television by a certain number of times is repeated to express the residual state of the viewer's residence. By connecting a video camera and a video tape recorder installed at a predetermined location in the residence, the intruder's intrusion status can be recorded, so that the intrusion situation of the intruder can be recorded on the recording surface of the video tape. The playback operation makes it possible to check through the television's CRT and speakers.

However, a passive security effect is provided in a pseudo-security function that turns on / off the power of the television a certain number of times, or in a security function that connects a video camera and a video tape recorder to record an intruder who invades the residence and records it on a video tape. There is a possibility that an intruder can easily detect the crime prevention method, and since the intruder takes a way of recognizing the crime state after the invasion of the crime is completed, there is a disadvantage that the intruder can not be prevented in advance.

Accordingly, the present invention has been made in view of the above-described circumstances, and when security data which detects the occurrence of an intruder is transmitted by a television installed in one residence, the two-way communication is possible for each of the plurality of televisions installed in the plurality of settlements. It is an object of the present invention to provide a method for controlling security by two-way communication of a television which receives the transmitted security data from another television and alerts the occurrence of an intruder.

According to the security control method by the two-way communication of the television according to the present invention for achieving the above object, the first step of setting the security mode in the television of one side of the plurality of televisions respectively installed in a plurality of residences, and the crime prevention A second step of detecting a movement of an intruder who has entered the residence on a television set in one mode; a third step of wirelessly transmitting security data according to the detection of an intruder's movement from the television of one side; and wireless transmission from the television of one side The fourth step of receiving the recognized security data from the television of the other residence and recognizing the security data received from one television on the other television, and invading an intruder into the residence where the television of one side is installed. Interactive two-way television consisting of a five-stage alert It provides a security control method of the new.

According to the present invention configured as described above, two-way communication is possible for each television set in a plurality of settlements, and the residences are settled by the television of one side while the security mode is set in one television. When an intruder detects an intruder's intrusion, the security data is transmitted to the other side's television. If the other side's television receives security data from one side of the television, the one side's television is installed in the residence. In addition to displaying an intruder's intrusion state in the form of OSD display characters, the intruder can make a voice alarm in the form of a voice alarm message.

Next, the operation of the present invention made as described above will be described in detail with reference to FIGS. 1 and 2.

First, in a state where the first and second televisions 100 and 200 installed in different residences are set to enable bidirectional communication, for example, the security mode is activated by a key operation by the first function setting unit 16 of the first television 100. When set, the first motion detection sensor 34 of the first television 100 detects the intrusion of the intruder existing in the front of the first television (100).

In this state, when an intruder enters a residence where the first television 100 is set, the first motion detection sensor 34 detects the intruder's movement and generates a detection signal. The first microcomputer 42 receives the digitally converted sensed data by the first signal converter 36 to recognize the intrusion state of the intruder and generates preset security data to generate the local oscillation by the signal mixer 38. It is matched with the frequency signal to be wirelessly transmitted to the predetermined frequency band through the signal transmitter 40.

At this time, the second signal receiver 68 of the second television 200 in which the security mode is not set receives the security data signal transmitted from the signal transmitter 40 of the first television 100. 2 The micro-communication 92 is a state in which an intruder intrudes in the residence where the first television 100 is installed by receiving the decoded security data that is waveform-processed through the second waveform processing unit 70 and the second signal decoder 72. If the power of the television is turned off and the second power circuit unit 74 is recognized, the power is turned on.

Subsequently, the second microcomputer 92 of the second television 200 controls the second OSD signal processing unit 76 to generate OSD display information for alerting the intruder to the other residence. By performing an analog conversion through the 78 to undergo the image processing operation of the image processing unit 58, as shown in FIG. 2, the OSD such as generation of intruders in the X × X house on the screen of the second CRT 60, for example. The display text is displayed on the screen, and the second voice memory 80 is read-controlled so that a voice alarm message for alarming an intruder's invasion state is read and decoded by the voice decoder 82. The voice is output through the second speaker 64 through the voice processing operation of the voice processor 62.

In the present invention having the above-described embodiments, the security operation in the state where the security mode is set in the first television 100 among the first and second televisions 100 and 200 has been described, but in the second television 200 Even when the mode is set, the security mode can be executed by the same operation as that of the above-described embodiment.

According to the present invention made as described above, the two-way communication between a plurality of televisions located in different residences each possible to transmit a certain security data to the other side of the television when an intruder is detected on one side of the security mode is set As a result, the other television can be alerted to an intruder's invasion in the other's residence, so that theft accident caused by the intruder who has entered the residence where the viewer is absent can be prevented.
