Description of the Invention (1) [Field of the Invention] The present invention relates to a video conference system and a method for implementing the same, and particularly to a video conference system for a wireless internet machine and a method for implementing the same.背景 [Background of the invention] Modern communication and communication technology are changing rapidly, which greatly shortens the distance in space. The birth of the video conference system allows us to bid farewell to the era of catching the wind and catching the shadows, and to reach a new world with sound and shadows. The advantages of the video conference system not only can improve the efficiency of the office, shorten the decision-making time, but also improve the timeliness, avoid the waste of lengthy traffic time, greatly shorten the distance, and enter into opportunities for communication with each other; whether it is a comprehensive decree or global Sex education training and technical seminars, etc., video conferences have greatly improved the efficiency of enterprises. Simply put, the video conference system is a video conference system 10 that uses the same protocol standard as itself and the other party. It uses compression and decompression technology to bi-directionally transmit data, video images and sound, and this transmission method is through the data line 20 Such as Integrated Services Digital Network (ISDN), Asynchronous Transfer Mode (ATM), Public Switched Telephone Network (PSTN), Ti line or satellite, etc. Transmission media transmission (as shown in Figure 丨), so that the video and sound at this end will appear on the other end of the TV 30, which is called a video conference system. However, ‘some video conferencing systems are too expensive to build and must be implemented with a computer or TV. On the other hand, the location of the video conference is fixed because it ’s connected to the Internet through a cable’.
