Design of video transmission system based on IMX6ULL

With the continuous development of the Internet of Things, vehicle systems, and smart homes, the demand for video transmission systems is growing. The existing video transmission system has poor adaptability and has problems such as blurred and stuck video images under low bandwidth conditions, resulting in poor transmission quality. To solve this problem, a video acquisition and transmission system based on the IMX6ULL processing unit is designed and implemented in this paper. The system realizes efficient and reliable video streaming transmission through a three-layer architecture design of embedded devices, relay servers, and receivers. The system adopts a communication protocol based on TCP/IP and combines a video quality control algorithm to effectively solve the problem of video transmission under changing network environments. Experimental results show that the video transmission system can maintain the clarity and smoothness of video images under fluctuating bandwidth conditions, has good adaptive capabilities, and ensures the best user experience.
