Abstract
Description
As personal handheld communication devices such as mobile phones, PCS, two-way pagers, mobile satellite phones, and IMT2000 are spreading, researches for video and data transmission through them are already in progress and commercialized. However, this image and data transmission is convenient, but there is a problem that state secret and company secret data can be transmitted without sanctions from national security agencies, national public research institutes, private research institutes and development offices. In the present invention, in order to solve this problem, indoor and aisle-mounted signal generators have a portable communication device that receives this signal to block video and data transmission.
As wireless transmission of video and data through portable communication devices becomes possible, it may be possible to circumvent national confidentiality, research and development contents of research institutes, and important information of the company without any restrictions. There is no.
When a passage signal generator generates a signal indicating whether a portable communication device enters or exits a room, and a signal forbidding the transmission of images and data from the indoor signal generator, the signal is recognized after entering the room. The mobile communication device that detects the data is automatically prohibited from transmitting images and data. The prohibiting method is a part of inputting data to connect a digital device such as a computer to transmit data and images, a video camera and a digital camera. Multiplexer is used to block the input of video and the output from the built-in camera to connect to an external video device such as a switch or multiplexer, or to prevent video and data from being selected by the multiplexer that selects audio, video and data. There is a driving method.
1 is an overall configuration diagram
2 is an indoor signal generator
3 is a detailed block diagram of a mobile communication device;
The present invention is installed inside the passage as shown in Figure 1 is a passage-mounted indoor signal generator 100 for generating a signal indicating that the mobile communication device has entered the room, and a signal to inform the mobile communication device that the outdoor came out The indoor signal generator 300 which is installed in a room that needs to prohibit image and data transmission, and which generates a video and data transmission prohibition signal and a normal operation signal, is installed inside the passage-mounted outdoor signal generator 200 which generates a path. Only when it is recognized that it has been entered, it is composed of a portable communication device 400 that automatically prohibits the transmission of video and data according to the signal or operates normally. The passage-mounted indoor and outdoor signal generators 100 and 200 are simple signal generators that generate different signals to distinguish whether the portable communication device enters a place where data transmission is prohibited or out of a prohibited area. On the other hand, the indoor signal generator 300 installed indoors and generating a video and data transmission prohibition signal and a normal operation signal is configured as shown in FIG. 2, and a desired one of an image and data transmission prohibition signal or a normal operation signal is input through the input device 301. When selected, the controller 302 drives the display device 304 according to this signal to inform the user in the room whether the current room is a video and data transmission prohibition zone or a video and data transmission zone, and also the signal generator 303. After driving to generate an image and data transmission prohibition signal or a normal operation signal is converted into an RF signal through the RF conversion and amplification unit 305, and is amplified and transmits the signal through the antenna 306. 3 is a detailed block diagram of the portable communication device 400. When the signal detector 401 detects a signal generated from the passage-mounted indoor signal generator 100 installed inside the passage when the user moves indoors, The controller 402 is notified of this, and the controller 402 stores in the internal memory that it is currently in the place where the image and data transmission is prohibited. On the contrary, when the user moves outward, the signal detection unit 401 detects a signal generated from the passage-attached outdoor signal generator 200 installed outside of the passage and notifies the controller 402 of the current image. And from the place where data transfer is prohibited is stored in the internal memory.
When the mobile communication device enters the video and data transmission prohibition zone, the signal detected by the indoor signal generator 300 is detected by the signal detector 401 and input to the controller 402. When is detected, the controller 402 drives the multiplexer 1 404 to block the video signal input through the video input terminal 403 and the video signal output from the built-in camera 414 and select ground, and also the data input terminal. The multiplexer 2 406 is driven to block digital data input through 405 and to select ground, and amplifies the voice input from the microphone 407 even when an image and data transmission mode is selected through the input device 413. After multiplying by the unit 408, the digital unit converts the digital signal through the D / A converter 409 and then selects only the compressed digital voice signal through the voice compression unit 410. It drives a Lexus 3 411. The digital signal output from the multiplexer 3 411 is now transmitted through the portable communication transmitter 412.
If the 'normal operation signal' is detected or no signal is detected, the controller 402 allows the multiplexer 1 404 to select the image input terminal 403 and the built-in camera 414 selected by the user, and the multiplexer 2 406. ) Selects the data input stage 404 and the multiplexer 3 407 drives to select the desired audio, video and data selected by the user and transmits this signal through the portable communication transmitter 412.
Video and data transmission through personal mobile communication devices such as mobile phones, PCS, two-way pagers, mobile satellite phones, and IMT2000 enables national and national security agencies, state and public research institutes, private research institutes, and development offices to ensure that state and corporate secrets are not sanctioned. There is a problem that can be transmitted and can solve this problem.
