video and data signals and sends them to the remote end in real time by using the existing communication network and digital signal compression technology, so as to realize real-time, visual and interactive information communication and further promote the information communication, cooperation and decision-making efficiency of users in various industries, such as point-to-point, point-to-many and many-to-many. In online classes, business meetings, remote training, online recruitment, remote consultation and other scenarios, the video conference system has the advantages of convenience and efficiency.
At present, the video conference system on the market has a variety of solutions, such as conference panel, Smart Camera + omnidirectional microphone + TV, desktop video conference screen, video conference all-in-one machine, etc., which can meet the needs of remote collaboration and video conference in different user groups and different application scenarios.
Conference terminals are mainly deployed in various conference rooms or offices for video conferences, which are used to collect, encode, decode and transmit audio signals in conference rooms, and display relevant information through connecting televisions or projectors. Clear image acquisition, high-quality video imaging, high definition audio and good communication functions are the most basic functions of intelligent video conference system, but this puts forward higher requirements on its hardware performance. The core board of Qiyang RK3399 is based on the six-core processor of Ruixin micro RK3399. It adopts the design of dual-core Cortex-72 plus quad-core Cortex-A53 and large-size cores. The Android operating system and rich interfaces support multi-function expansion. It is one of the best choices for building terminals such as conference panel, video conference all-in-one machine, desktop conference terminal and video conference host.
What are the advantages of RK3399 in creating video conference terminals?
Video image acquisition and output
RK3399 uses Mali-T860 GPU, supports 4K VP9/ H.265/H.264 ,1080p multi-format video decoding, and 1080p H.264/VP8 video encoding. Efficient video encoding and decoding technology provides faster encoding and decoding speed and lower latency, providing a smooth and high-definition remote experience.
RK3399 has HDMI display interface and MIPI-CSI camera interface. The camera interface can match a variety of cameras, and connect the wide-angle zoom high-definition camera in the video conference terminal. The large wide-angle camera can bring all the participants into the video picture. The zoom function can be combined with face recognition, sound source positioning and other technologies to automatically adjust the far and close-range picture and focus the speaker. The high-definition camera has accurate and natural color restoration, clean and exquisite picture quality, and provides high-quality video picture. The HDMI interface is connected to the high-resolution display, which can output 4K/1080p ultra-clear resolution video, restore the meeting scene and bring an immersive meeting experience. RK3399 also supports dual-screen display and can connect two high-definition screens. Video conferences and display documents are presented separately to create a more convenient conference service.
Audio function
RK3399 has excellent audio function and supports 8 input channels of digital microphone array. The built-in array microphone of the video conference terminal can realize 360-degree omni-directional and long-distance high-quality radio. It can automatically gain human voice and eliminate echo and noise with audio processing algorithm. The audio interface supports Hi-Fi speakers to realize clear and pleasant sound quality and no noise, ensuring smooth and efficient conference communication.
Network, interface, and system
RK3399 supports various communication modes such as Gigabit network port, 2.4G/5G dual-frequency Wi-Fi, Bluetooth, 3G/4G, etc. It can also be configured with NFC, zigbee and other communication modules according to user requirements.
RK3399 interface is rich and scalable, with a variety of audio and video interfaces, such as USB2.0 and USB3.0, which can be connected with mouse, keyboard, U disk, and expand microphone and other equipment;
RK3399 adopts Android operating system and an open system platform, which is convenient for software companies to carry out secondary development. It can install various mainstream conference software and communication protocols, support wireless OTA upgrade, realize plug-and-play video conference terminal, and can communicate with other devices remotely, synchronize in real time, and improve the efficiency of remote conference.
In addition to RK3399 core hardware, Qiyang I. MX8M Plus also has excellent audio and video processing technology, which can be applied to video conference terminal solutions.
