4K refers to the 4K resolution based on the integration of HDR and WCG that is high dynamic and wide color gamut of a high-definition display technology. HDR refers to high dynamic range images. Different from ordinary images, high dynamic range images can provide many image details and dynamic image range. The final high dynamic range image can be synthesized by referring to the LDR image with the best details at each exposure time, so as to objectively reflect the real visual effect. Under the influence of media convergence, 4K video and audio signal transmission has become one of the important measures to ensure the quality of signal transmission and speed up the signal transmission . This study provides relevant theoretical reference for relevant researchers and effectively enriches the theoretical research in this field. At the same time, it can also point out the direction for the long-term development of 4K video and audio signal transmission and provide some practical guidance and help. Describes the existing video and audio signal transmission system, 4k video and audio signal transmission technology, different video and audio signal transmission.
