Abstract

PURPOSE: A method for monitoring a remote place by using an automatic response mode is provided to add a manager mode function to an absent automatic response mode in a packet network-based IMT2000 video phone terminal, so that a user can see a screen and an image of other party during a call, and to assign a password function to the absent automatic response mode, thereby using as a remote monitoring mode. CONSTITUTION: An automatic response mode is set in a terminal located in a monitoring area. A transmitter calls the terminal. A monitoring terminal checks an elapse of a certain time or the number of rings, and delivers a prestored absent announcement message. The absent announcement message is received, and a manager password is transmitted to the monitoring terminal. The monitoring terminal decides whether the inputted manager password is identical with a preset password. If so, the monitoring terminal delivers video and audio signals through a camera and a microphone.

Description

Remote watching method of using auto answering mode}

A common function of the current video telephone system is a call function through video and audio. Another additional feature of this is the missed answering function and the remote monitoring function. The remote monitoring function refers to a function of viewing a remote image and sound through a receiving device. On the other hand, the automatic answering function is to answer automatically when a call request continues for a predetermined number of rings for an incoming call in the absence, and to answer automatically, and send a guide message to record the voice and video if the other party wants, This stored message refers to the function that the user can listen to later.

Figure 1 shows the general operation flow diagram of the existing automatic answering function. When the auto answer function is set, if the ring is turned on for a certain number of rings, it automatically responds and sends a fixed screen and voice guidance message. After a certain tone, the other party leaves a message and the call ends. Even if there is a remote monitoring function, the other party does not need to receive it, and if only a call is made, it is automatically connected and can receive the video and audio of the other party. If you look closely at these two features, there are a lot in common, but most existing products take the form of implementing these features individually. In this sense, a method for implementing a remote monitoring mode by using an existing auto attendant function that has been implemented is raised as a problem to be solved in terms of preventing the dual function of the terminal and reducing complexity.

The present invention is to add the administrator password function to a conventional video telephone terminal that implements the automatic answering function to enable the remote monitoring.

1 is a method of transmitting and receiving an out-of-office guide message using a conventional auto answering function

2 is a block diagram of the present invention

3 is a remote monitoring method using an automatic response function according to the present invention

The present invention comprises the steps of setting an automatic answering mode to a terminal in the surveillance area, calling a terminal in the surveillance area from the sender side, and checking the elapsed time or the number of rings in the monitoring terminal, and accordingly stored in advance. Transmitting the absence guide message, transmitting the administrator password to the monitoring terminal after receiving the absence guidance message, and in the monitoring terminal, determining whether the input administrator password matches the preset password and matching the camera and the microphone. Remote monitoring method comprising the steps of transmitting the input video and audio signals.

Fig. 2 shows a configuration of a video telephone applicable to the present invention, and Fig. 3 shows an operation flowchart according to Fig. 2 above. Hereinafter, the present invention according to FIG. 2 will be described.

A camera unit for obtaining an image signal, a camera driving and signal input unit for driving the camera unit and inputting an image signal photographed by the camera unit, and a camera digital signal for processing the image signal output from the camera driving and signal input unit Controlling the processing unit and the camera digital signal processing unit to compress or restore the image signal, and to control the signal processing of the camera digital signal processing unit to display an image on a monitor; System control unit for performing missed guidance and recording of phone number, password matching for remote monitoring input from the other party and transmission control of camera image, and moving picture processed by the camera digital signal processor. Monitor to display on the pressure And a communication control and interface unit for controlling image communication and performing signal input / output under the control of the system control unit, and controlling information or image information of the system control unit, and an absence guide message and answering phone number. And a handset connected to the memory unit 309 and the communication control and interface unit to perform voice transmission and reception.

The present invention comprises the steps of setting an automatic answering mode to a terminal in the surveillance area, calling a terminal in the surveillance area from the sender side, and checking the elapsed time or the number of rings in the monitoring terminal, and accordingly stored in advance. Transmitting the absence guide message, transmitting the administrator password to the monitoring terminal after receiving the absence guidance message, and in the monitoring terminal, determining whether the input administrator password matches the preset password and matching the camera and the microphone. Remote monitoring method comprising the steps of transmitting the input video and audio signals. Hereinafter, with reference to Figure 3 will be described in detail. First, set the auto answering mode and the password for monitoring at the communication terminal in the monitored area at the remote site, and the caller dials the communication terminal with the password set for the monitoring and sends a predetermined tone or message from the missed answering mode. Enter the password accordingly, and the communication terminal of the surveillance area receiving the input compares the previously set password with the currently input password and transmits the video and audio signals input from the camera and the microphone to the other terminal.

The present invention provides a password function for remote monitoring to the missed automatic answering mode implemented in the video phone terminal to be utilized as a remote monitoring mode.
