Distributed Conference System & Intelligent Conference Room

2023 Guangzhou DSPPA Audio Co., Ltd.
Solution Description

With the progress of society, the intelligent conference system has gradually shifted from single conferences to multi- cross-regional ones. With the distributed conference system, the industry's all-IP conference solution is developed, and the audio, video and control signals are transmitted, managed and controlled through the network by the input and output nodes and distributed control software distributed in the conference room systems, realizing the information sharing among conference rooms, enterprises and between individuals and enterprises.

There are 3 sub-systems included in our intelligent conference system as follows:

● 5G WiFi Conference System (D7201/D7301)

● 4K Distributed Audio&Video Management System (D6900)

● Audio System (Mixer, AMP, Speaker)


5G WiFi Conference System (D7201/D7301)

    Wireless Conference System far outweighs Traditional Conference System in terms of the need for a multi-functional hall, press conference hall, temporary venue,  etc., which can be quickly and easily set up and shifted.

  With the development of technology and the advent of the Internet era, the rate of smartphone ownership is almost 100%, combined with WIFI technology, communication is more convenient.

4K Distributed Audio&Video Management System (D6900)

The signal interconnection can be achieved between each area in the system, the signal of each meeting room can be retrieved in real-time, the signal of all meeting rooms can be monitored and dispatched in real-time by the machine room, and the equipment in each meeting room can be controlled in real-time. The signal interconnection can be achieved between each area in the system, the signal of each meeting room can be retrieved in real-time, the signal of all meeting rooms can be monitored and dispatched in real-time by the machine room, and the equipment in each meeting room can be controlled in real-time. Users only need to take the wireless device to conduct linkage control and real-time scheduling of signal sources in different zones, regardless of the signal source or peripheral equipment. No compression, no loss, and no delay transmission make the conference room less in cost, and user-friendly in management from construction, management, and control to after-sales service.

Audio System (Mixer, AMP, Speaker)

Sound reinforcement system, mainly composed of speakers, power amplifiers, mixers, microphones, audio sources, etc., is applied in meetings, speeches, reports, etc. As professional audio processing equipment, mixer and audio processor keep voice clear, and distortion-free and no acoustic feedback whistling, etc. Combined with the suitable speaker, the sound pressure margin is sufficient, sound field distribution is balanced and sound and image positioning is accurate.


 System Functions

5G WiFi conference system section

● High confidentiality encryption technology

It adopts 128-bit AES encryption and WPA/WPA2 wireless security technologies to guarantee the confidentiality of meeting information

● Highly reliable transmission technology

Using the 5GHz communication frequency band, it has stronger bandwidth and communication speed, with good resistance to electric waves and electromagnetic interference, ensuring faster and more stable wireless signal transmission.

● High-fidelity sound quality, no-latency transmission

It adopts uncompressed audio transmission technology, with 20Hz-20kHz perfect sound quality, and a 48K sampling rate; The no-latency Dante-based conference system seamlessly integrates with the 5G WiFi wireless conference system.

● Noise suppression processing

The host is embedded with a high-performance quad-core CPU processor, adopts soft mixing digital audio processing technology, and has an ARM7 processing chip to effectively prevent sound from returning. The microphone has a built-in high-fidelity speaker, which is automatically muted when the microphone is turned on, and it is not easy to produce howling, ensuring the quality of the meeting.


4K IP-Based Distribution Matrix System section 

● Intelligent reservation for the more convenient conference

In the past, conflicts of meeting resources were frequent, such as different departments holding meetings in the same meeting room at the same time, which could cause embarrassment. The distributed meeting room reservation function perfectly solves the problem by supporting direct reservations on the mobile app. It automatically checks the usage time of the meeting room, sends meeting notifications, retrieves the available meeting room in real-time, and sends warnings if there is a conflict.

● Fully decentralized design for more secure intelligent control

The distributed system integrates a central programmable control function, with a single node used as independent central control. The system does not need a CPU as it has an AI logic management unit or environment control interface machine.  As each module control work independently, the module control failure will not affect the operation of the whole system, and only the faulty node needs to be dealt with, ensuring the stable operation of the whole system, and also facilitating system maintenance.

● Cross-network transmission teleconferencing

Managers can efficiently share and synchronize voice, video and data files in real-time with teams and customers around the world with a simple operation through the touch panel interface. The distributed system supports interoperability of audio, video and control signals across the Internet, requiring only a 4G wireless network or regular broadband instead of dedicated network lines.

● Hierarchical rights management makes meetings more confidential and secure

The hierarchical right management function of the distributed system distinguishes administrators and operators, making it possible for simultaneous meeting operation and device and permission management in local or subordinate areas. It ensures that the operation authority is divided to the finest detail in order to meet the different customized needs.  Administrators at all levels can well grasp the degree of authority delegated to areas, greatly improving the confidentiality of the meeting.

● Visual touch control screen

The distributed system provides a reliable network connection between the touch screen and the controlled device. On the touch screen, the control status and the working environment condition of the controlled device can be viewed in real-time. Feedback can be acquired from text, button status, image display, video monitoring, etc., to achieve more intuitive interaction between humans and machines. The user only needs to conduct one-key touch so that each channel audio and video signal in the form of any multi-screen can be displayed on the large screen, achieving image roaming, overlay and zooming and other effects.
