With the popularization of the use of video conferencing systems, users will have more comprehensive and deeper regulations on the role of the Console for PA System. In the presentation of the basic elements, video conferencing should also consider increasingly prominent user requirements, such as the increase in the total number of interactive targets, the improvement of video picture quality, and the improvement of security. This is also a further sound regulation clearly put forward for the natural environment required to complete the Console for PA System. With more sound technical standards, the Console for PA System can produce higher-quality audio-visual interactive services, and can promote the further marketing and promotion of the use of video conferencing.

The key shortcomings of current video conferencing application scenarios are as follows:

1. The development trend of Console for PA System to this day, its bottom support point network is mainly IP network, which is also the development trend of communication network. As everyone knows, the traditional IP network does not produce QOS guarantee. It was originally designed for simple data communication, it was open to the outside world and shared resources, and its characteristic was "doing what you can." To show many instant multimedia communication service items in such a natural network environment, there must be some additional countermeasures.

2. The bandwidth problem of the access network. The bandwidth resources of the communication network required by the Console for PA System have shortcomings in the access network. The bandwidth of the main pole transmission network is generally of the order of Gb/s and Tb/s, which is very colorful, while the access network at the user terminal device looks relatively anxious.

3. Internet browsing is hindered. The Console for PA System must transmit various information content such as video, voice, image, data information, manipulation, etc. It must use a lot of network resources, such as creating connections, obtaining real IP addresses, and several applications. Port number, and the server firewall, server proxy, wireless router and other equipment in the specific network have carried out numerous restrictions on the actual operation of network resources.
