1. Network adaptability (paperless conference system, ultra-thin one lift)
The adaptability requirements of the video conferencing system network include two aspects: one is the adaptability of the docking method, that is, the end user can access the system through many existing methods: the second is in the case of extremely strict network security measures, various The performance of network devices, including the penetration of firewalls, still meets the requirements of video conferencing capabilities. Mainly in the following points:

(1) In the same video conference system, the configuration of each terminal device is not required to be completely consistent, and only needs to comply with relevant international standards.
(2) Through the special internal data stream forwarding of the MCU, the network bottleneck between different network service providers can be easily avoided, and the data between different regions and different networks can be ensured smoothly and stably.
(3) Unique encoding processing, automatically adjust the code stream size. Audio and video data have network error correction and sufficient packet loss prevention mechanism in network transmission.
2. Multi-screen conference
The system provides multi-screen display such as 2, 3, 4, 5+1, 8+2, 12+1, 16 split screens
Function, each sub-picture can be selected at will, or you can freely set the position of a sub-site in multiple pictures. A sub-picture can be patrolled or switched by voice excitation. During the conference, various split screen modes can be switched in real time, and the screen display can be switched to the desired split screen mode at any time.
There are also three selection modes for each screen: you can display a specific venue; you can set the rounds of each venue; you can also switch the venue by voice excitation. For example:
In the three-screen mode, the above centered screen can be set to manual switching, set to the main venue screen; when the lower left corner of the screen is set to voice excitation, the floor of the speaking site will appear in the lower left corner; the lower right corner of the screen will be When set to automatic round robin, the rest of the venues will be automatically tracked according to the time set by the system, and each sub-site screen will be displayed one by one in the lower right corner. During the conference, various split screen modes can be switched in real time, and the screen display can be switched to the desired split screen mode at any time.
3, dual-stream conference (paperless conference system, ultra-thin one lift)
Dual video streaming means that McU can transmit two dynamic video signals simultaneously between conference sites. In dual video streaming, the first video stream mainly transmits the moving image signal captured by the main camera, and the second video stream may be the moving image of the auxiliary camera, or may be a PC picture, a DVD dynamic picture, a slide or an electronic whiteboard. Wait. Supports up to UXGA (1600X1200 pixels) resolution when transferring PC pictures.
Both video streams can be H.264 encoded, ensuring high definition of mainstream and auxiliary streams at low bandwidth. The video codec terminal has built-in H.239 dual-stream protocol, which eliminates the need for an external dual-stream box and is more convenient to use.
4, image round robin function
The MCU can separately select and view any sub-site image in the main site without affecting the display of the carousel images of other sub-sites.
The MCU image round robin function includes the main venue round robin, broadcast round robin, and custom round robin function:
(1) The main venue is patrolled. The main venue can patrol the images of each sub-station, so that the conference chairperson can keep abreast of the situation of each sub-station, control the atmosphere of the venue and the progress of the conference.
(2) Broadcasting rounds. All the venues can watch the images of each venue together, fully mobilize the enthusiasm of each venue, and better adjust the atmosphere of the conference.
(3) Custom round robin. Screen the venues participating in the conference and exclude venues that do not participate in the round robin.
5, conference control function
The MCU has a variety of conference control methods: chairman control, director control, voice excitation, and automatic round robin. The conference control function includes: specifying/adjusting the conference executive chairman, the representative to apply for the speech, the subtitle setting, the multi-screen setting, the multi-screen round robin, the site sound reinforcement, the site mute, the site mute, the addition of the site, the deletion of the site, the call site, and the hang up. Meeting place, meeting convening, ending meeting, offline re-invitation, advance notice at the end of the meeting, group invitation online, home round patrol, broadcast round patrol, terminal control, etc.
(1) Voice stimulation. Broadcast the loudest voices without manual intervention.
(2) Director mode. The administrator controls the conference through the MCU management platform.
(3) Chairman mode. The conference is controlled by the chairman terminal. (Paperless conference system, ultra-thin one lift)
(4) Round robin mode. The scheduled time is displayed in turn.
(5) Speech mode. The main venue has a multi-screen view of the breakout venue, and other venues only watch the main venue.
6, redundancy and stability
(1) Support MCU multi-level cascading, network optimization, and cluster fault tolerance. When an MCU crashes or loses power, other MCUs will automatically take over to ensure normal operation of the system.
(2) Multiple MCUs can automatically load balance each other, intelligently judge and automatically provide the MCU with the lightest load and the best network condition for stream forwarding.
7, security management
The functions of remote conference management include user management, conference reservation management, conference configuration management, conference notification, conference suspension, conference extension, and server resource statistics.
(1) Strict hierarchical authorization management mechanism to clarify the permissions of each user and effectively prevent illegal user intrusion. (2) A powerful conference chair authority control mechanism to ensure the smooth running of various meetings.
(3) Support multiple operating systems such as Windows and Linux to meet the needs of different users. (Paperless conference system, ultra-thin one lift)
