Description

 Portable audio and video desktop conference equipment and system

Technical field

The invention relates to the field of communication technologies, in particular to a portable audio and video desktop conference device and system.

Background technique

As a very important communication channel in various industries of today's society, the conference system is divided into the following stages.

The original form of meeting is to bring everyone together to discuss. This is actually a simple form of meeting. Due to conditions, there may not be any electrical equipment in the meeting. The drawback of this form of meeting is that it is limited to fewer meeting members. Group meetings, and the venue of the meeting can only be conducted locally.

With the continuous advancement of science and technology, in order to meet the needs of large-scale conferences, conferences in the form of microphones and speakers began to take shape. The venues were generally held in the form of speaker devices that were connected to the scene at the same time. Get information through the speaker device. Although this type of meeting meets the requirements of large-scale conferences, it is difficult to conduct orderly discussions when interacting with participants. At the same time, the layout of the venue requires a large amount of manpower and material resources, and needs to be laid out in advance. Meeting at any time has no advantage in teleconferencing and video conferencing.

People continue to make breakthroughs in audio, video and other technologies. High-fidelity voice quality, high-definition image quality conference system; this system provides high-quality audio signals, high-definition video dynamic images and images; can express physical data and accurate data.

At present, most of the mainstream conference systems are based on core audio and video processing equipment plus peripheral speakers, microphones, and desktop conference microphones. The central office of the main venue and the conference venue are equipped with an MCU processor, which is mainly used to handle the venue or local area. The video access service aggregates local audio and video services to the MCU. After being processed by the MCU, the data is distributed to the conference sites to implement local and remote conferences. The conferences are usually fixed in office spaces, and conference equipment such as video conference cameras and video. The conference desktop microphone (goose neck microphone) is fixed in the conference room; in addition, the desktop conference microphone commonly used in the conference room is relatively simple, and only provides audio input function.
