Abstract At present, we are in the era of a big video explosion, and various emerging video technologies have sprung up, forming a situation in which multiple video interface standards coexist. Therefore, the compatibility of video interfaces has become a prominent problem. This paper proposes a scheme based on STM32, combined with high-speed video processing chip to HDMI interface 4K video stream real-time LVDS interface, and selects the code stream of different formats for test verification. After testing, the scheme can realize the separate output of audio and video data streams, and at the same time support audio and video parameter conversion to meet the expected design requirements, which will contribute to the promotion of ultra-high definition digital TV.
