Abstract

A device and a method for parallel video transmission based on visible light belong to the technical field of wireless video communication. Real-time, ultrahigh-speed and distortion-free wireless transmission of field video signals has yet to be achieved in the prior art. Based on the fact that a camera can output digital video signals in parallel via multiple channels, video signals are wirelessly transmitted in a multi-channel parallel and multi-transmitter multi-receiver manner through a video acquisition and pixel splicing module, a plurality of LEDs, a plurality of photoelectric detectors, a pixel separation module and the like in the invention. There is no data transmission bottleneck. There is no need for any digital video signal compression processing. The integrity of video signals is ensured, and distortion is avoided. The visible light channels for visible light communication are independent of one another, so that crosstalk in radio-frequency communication is avoided. Meanwhile, compared with radio frequency communication, there is no electromagnetic radiation, no harm is caused to the human body, and the work of other electromagnetic sensitive devices is not hindered.

Description

technical field

[0001] The invention relates to a device and method for parallel video transmission with visible light, and belongs to the technical field of wireless video communication. Background technique

[0002] 2K, 4K and other ultra-high-definition and ultra-high-resolution video technologies have higher requirements for bandwidth, but radio frequency communication cannot meet this requirement. Compared with radio frequency communication, visible light communication has the basis of high-speed digital communication because the commonly used LED light source can be modulated at high speed; now the data transmission rate of visible light communication has reached 3.4Gbit / s, and the limit data transmission rate of Wi-Fi as radio frequency communication Only 700Mbit / s, therefore, visible light communication is more suitable for video transmission. However, existing technologies have not yet fully exploited the high data rate advantages of VLC. For example, a Chinese pa...
