Video conferencing uses a communication system consisting of various terminals and lines to view a video screen between people in distant places, and to conduct a meeting in an atmosphere of being together in a conference room. Video systems include conference room video conferencing systems and desktop video conferencing systems.

It is called video conferencing or TV conferencing because it allows users to visually present information related to the participant's appearance with voice as well as meetings between distant people. If the meeting between corporate headquarters and branch offices or conference halls is separated and it is difficult to gather in one place and conduct meetings, it is done remotely using a computer network.

The video conferencing system basically installs cameras, video compression codecs, monitors, microphones, and speakers in both conference rooms, and connects them to two-way video and audio lines, or dedicated lines. T recommends the use of a global standard for this purpose. In recent years, there are products that have a function of meeting with a personal computer, so that computer data can be shared with each other, and a function of drawing or drawing with an electronic pen on both monitor screens is being utilized.

Herein, the name of the contact is a liquid crystal, such as '01 John: message ', by combining the order of access to the conversation and the name of the subject corresponding to each IP address previously stored in the memory 160 of the codec unit 100. Mark on. At this time, 01 is the first participant of the conversation (always 01 when talking to one person), and John is the name corresponding to the previously stored IP address.

In addition, when an important character or a notice is notified during a conversation, pressing a specific selection key (for example, 'important notification key') among the selection keys 122b provided in the keypad 122, the keyboard 120 of the person and the counterpart The corresponding key is activated (flashes) on the liquid crystal display 121. At this time, the flicker of the liquid crystal display 121 blinks until the sender finishes inputting the text and presses the 'Enter' button, and 'B' enters the replying letter and blinks until the 'Enter' button is pressed. In other words, the flashing signal of the corresponding key on the liquid crystal display must read and respond.

In addition, when a specific selection key (for example, a "backlight off key") of the selection keys 122b included in the keypad 122 is pressed during the conversation, the monitor displaying the conversation window W according to the user's preset setting ( 20) or the backlight of the liquid crystal display 121 is turned off. This backlight off function is applicable to the tactical imaging system and can be used in exhibition situations requiring concealment / hiding.

And many documents come and go in general meetings. It may be a general memorandum or a secret document. It is not accurate enough to deliver these on video and voice calls, and it is difficult to fully understand the person. You can also use e-mail separately, but it is a disadvantage that it is difficult to deliver quickly in case of a large amount, and sometimes the file transfer can be difficult due to the capacity limitation of the e-mail server.

In order to compensate for these disadvantages, the present invention can transmit and receive file data during video conferencing or text conferencing. When the USB memory 50 is coupled to the second USB port 123 of the keyboard 120, the central processing unit ( Under the control of 160, the file or folder of the USB memory 50 is displayed on the monitor 20 or the liquid crystal display 121, and after the user selects a specific file or folder through the keyboard 120, the keypad 122 is displayed on the keypad 122. When a specific selection key (for example, an "upload key") of the selected selection key 122b is pressed, it is transmitted to the opposing codec unit 100 through a text data transmission / reception path under the control of the central processing unit 160. . At this time, when the upload key is pressed, the phrase '01: John is ready to transmit the file 'is displayed on the dialog window of the monitor 20 or the liquid crystal display 121 of the counterpart and the other party.
