The controller(108) generates a control command corresponding to the code number output from the data recognizer. The video camera(109) commands the control signal generated from the controller. The data recognizer(107) further determines whether the remote control signal corresponding to a combination number for executing a specific control command is input by determining the frequency signal according to the number of the telephone.

Description

Remote control apparatus of video camera

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video communication device, and more particularly, to a remote control apparatus for a video camera for a user to actively control a video camera constituting the video communication device using a telephone remotely.

In general, a video communication apparatus installs a video camera at a remote location, encodes a video signal photographed by the video camera, and transmits the video signal to a modem of the user side via a modem through a modem. Then, the video data received through the modem of the user side is demodulated and then displayed on the monitor.

By the way, it is common for the video camera of the conventional video communication apparatus to be fixed in one direction, or to rotate by the set program in the monitoring camera system.

Therefore, the user cannot actively change the operation or the direction of the video camera at a remote location, so in order to change the operation or the direction of the video camera installed at a remote location, it is inconvenient to use, in which the user must go to a place directly installed and change it manually. there was.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a remote control apparatus for a video camera that allows a user to remotely control an operation or position of a video camera constituting a video communication device through a telephone remotely.

1 is a configuration diagram of a remote control apparatus for a video camera according to the present invention.

In order to achieve the above technical problem, a remote control apparatus for a video camera according to the present invention is a device for controlling the video camera of a video communication system for receiving a screen shot from a video camera installed at a remote site and displaying the picture on a monitor. A data recognizing unit for determining whether a remote control command signal corresponding to the combined number for executing the specified control command is input through a telephone line, and finding and outputting a code number corresponding to the input number in the table, the data And a control unit for generating a control command corresponding to the code number output from the recognition unit, and a video camera for executing the control command generated by the control unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the remote control apparatus for a video camera according to the present invention includes a telephone A 101, a modem A 102, a video signal processor 103, a monitor 104, a modem B 105, a telephone. A B 106, a data recognition unit 107, a control unit 108, a video camera 109, and a data conversion unit 110 are provided.

Here, the telephone A101, the modem A102, the video signal processor 103, the monitor 104 correspond to the user side communication block 1000, and the modem B105, the telephone B106, The data recognizer 107, the controller 108, the video camera 109, and the data converter 110 correspond to a system communication block 2000 installed at a remote location.

In addition, there is a telephone line between the user side communication block 1000 and the system communication block 2000 installed at a remote location, and these communication blocks are connected by an exchange 3000.

First, the basic operation of the video communication system will be described.

The user sets a specific position of a place where the user wants to receive an image signal, and after installing the video camera 109 there, inputs an execution mode such as a recording mode.

Then, the video signal photographed by the video camera 109 installed at a remote location is encoded by the data converter 110. Then, the modem B 105 performs modulation for transmission over the telephone line, and then transmits it to the modem A 102 on the user's side through the switch 3000.

Then, the image data received by the modem A 102 on the user side is decoded by the video signal processing unit 103 and displayed on the monitor 104 after performing the R, G, and B signal processing.

By this operation, the video signal captured by the video camera 109 installed at a remote location is displayed on the monitor 104 of the user side.

An operation of remotely controlling the video camera 109 installed at a remote place in the video communication system through the phone A 101 of the user side will be described.

When the handset of the telephone A101 on the user side is lifted, the switching device 3000 transmits a dial tone indicating that a dial tone can be dialed to the telephone A101.

When a user inputs a telephone number provided with a video camera 109 of a remote video communication system to telephone A101, switchboard 3000 transmits a call signal to telephone B106 via modem B105.

At this time, if the hook of the telephone B 106 installed at a remote location is not turned off for a predetermined time, the data recognition unit 107 transmits a response signal for receiving data to the switch 3000. Then, the switch 3000 transmits a signal tone for instructing data transmission to the handset of the telephone A101 via the modem A102.

In this case, when the combined number corresponding to the specified control command is inputted to the telephone A 101, the data corresponding to the combined number after passing through the modem A 102 is transferred to the modem B 105 via the switch 3000. Is sent.

For example, data may be composed of a combined number of eight digits, the first four digits may be set as a password, and the fourth four digits may be defined to indicate the type of execution command.

Execution commands include basic functions such as power on / off, zoom on / off, recording, stop, etc., as well as commands to instruct the video camera to rotate up, down, left and right in a specific number. Can be.

For example, if the password is defined as 2475, the command to rotate the video camera to the left direction is 1234, and the stop command is 2345, the user inputs 24751234 with the numeric buttons of the telephone A101, The number corresponding frequency signal is input to modem B 105 via switch 3000.

Then, the data recognizing unit 107 reads the frequency signal inputted to the modem B 105, reads the code number corresponding to each number from the table of the internal memory, and outputs it to the control unit 108.

The controller 108 outputs a control command corresponding to the input code number to the video camera 109.

However, since the input number corresponds to a control command for rotating the video camera 109 in the left direction, the controller 108 rotates the video camera 109 in the left direction.

Then, when the user inputs 24752345 through the telephone A101, the data recognition unit 107 reads the frequency signal inputted to the modem B105 via the telephone line. The code number corresponding to the number read by the data recognition unit 107 is outputted to the control unit 108 so that the control unit 108 applies a stop command to the video camera 109 to stop the rotation.

After defining the telephone numbers corresponding to the respective control commands in this way, the data recognition unit 107 reads them out so that the user can freely control the position change and execution mode of the video camera remotely installed through the telephone. It became.

As described above, according to the present invention, by easily controlling the position and execution mode of the video camera of the video communication system installed remotely through the telephone, there is an effect that the video communication system can be actively used as the user intends.
