Abstract

The invention discloses a light wireless transmission system for high-definition videos. The light wireless transmission system comprises a video server side and a video browser side, wireless data transmission between the video server side and the video browser end is performed through a Mesh network, the video server side comprises a kernel processing chip and a wireless transmitter module connected with the kernel processing chip, an image collecting interface is arranged on the kernel processing chip, and the video browser side adopts a computer and client-side video browsing software based on a Windows platform. According to the light wireless transmission system, long-distance transmission of 720P high-definition images under the condition of limited wireless bandwidth is achieved, a transmitting side device has the advantages of being light in mass, low in power consumption and the like, expensive application to mobile equipment with limited loads is facilitated, problems of major natural disaster scenes, large-scale mass meetings, important security scenes and the like can be assisted to solve, rear commanders need to know problems of real-time information timely to improve the decision response accuracy and timeliness and to improve the working efficiency.
