Description

Conference terminal interaction system and method supporting multiple agreements

This creation belongs to the field of network video conferencing technology, especially a conference terminal interactive system and method supporting multiple protocols.

With the development of Internet technology, video and audio codec technology, video conferencing products have been rapidly popularized, video conferencing for various software applications, and H.323-based terminal hardware video. The conference was widely used. The video conferencing system is a virtual meeting realized by network communication technology, so that dispersed users in the world can gather together to exchange information through various means such as graphics and sound, so as to help users to make timely messages outside a long distance. Communicate and share and develop application systems that work in sync. Videoconferencing assists the real and intuitive communication between members of the organization and plays a pivotal role in remote teaching and conferences. Video conferencing is mainly divided into the following three types:

First, the hardware-based video conferencing system: is the most commonly used means of implementation. The special feature is to use dedicated equipment to realize video conferencing. The system has high cost, simple use and convenient maintenance. The video quality is very good, the network requirements are high, and the high line quality requirements are required to ensure the running effect and stability.

Second, the software-based video conferencing system: to fully use soft The body to complete the function of the relevant hardware, mainly by means of the computer host to achieve the relevant hardware codec function. The feature is that it makes full use of the existing computer equipment, and the overall equipment cost is low.

Third, the network video conferencing system: based on the Internet, the focus is on the realization of very powerful data briefing or collaborative work, the minimum requirements for the network, completely based on the telecommunications public network-based operating methods, so that The relevant users are very convenient, do not need to purchase software and hardware equipment, just charge, but the video effect can be accepted by the average person.

Among them, the software video conferencing system is regarded as an important application of software video, mainly adopting the method of server and computer host architecture, setting MCU server, multi-screen processing server and multimedia server in the center; configuring on ordinary desk computer USB camera, headset and conference terminal software; high-performance computer, video capture card, conference camera and conference terminal software in the conference room. In the video conference, the operation and management of the conference is carried out using the operation interface based on the Windows operating system. When the video is connected, the video communication mode of the computer mainframe architecture mainly relies on the CPU to process the decoding of the audio and video. The biggest focus is cheap, easy to use, and easy to manage software. However, software video still needs to be improved in terms of stability and reliability, and the quality of video is generally beyond the hardware video system.

The hardware video conferencing system mainly includes embedded MCUs, conference room terminals, desktop terminals and other devices. The MCU is configured in the network center computer room (IDC), which is responsible for the processing and transfer of audio and video packets; the conference room terminal is configured at the conference site, and photography. Computers, microphones, and other peripherals such as televisions are connected; desktop terminals incorporate small cameras and LCD monitors that can be placed on a desk as a tool for video communication. The hardware video is based on the embedded architecture, and relies on DSP and embedded software to implement audio and video packet processing, as well as network communication and conference functions. Its biggest feature is its high performance and good stability. The disadvantage is that the price is high.

In summary, the combination of hardware and software video conferencing will undoubtedly achieve advantages and complementary benefits. However, the software video conferencing products on the market and the standard video conferencing terminals are not able to communicate well. Since most software videoconferencing products use different standards for message transmission conversion and video and audio decoding, although standard H.323 devices can be added to video conferences, they cannot be solved to make H.323 devices as software. The same as the client to which the video conference belongs, making it easy to integrate into the video conference. Therefore, there is a need for a system and method for adding an H.323 video conferencing terminal device to a software video conferencing session.

This creative department provides a conference terminal interactive system and method that supports multiple protocols. This creation can combine video conferencing systems of different communication protocols to realize the integration of various video conferencing products.
