The invention relates to a coaxial adaptive analog high-definition transmission anti-attenuation device and a method based on differential compensation. The device comprises a distortion information analysis module, a differential calculation module, an amplitude control module and a compensation signal superposition module. After original signals are processed through the differential calculation module, original compensation signals are obtained, the original compensation signals are then transmitted to the amplitude control module and are processed by the amplitude control module, compensation signals are then outputted to the compensation signal superposition module, the compensation signal superposition module superposes the compensation signals on the original signals, signals after compensation are fed to a coaxial line for transmission, the superposed compensation signals are used for cancelling distortion signals transmitted by the coaxial line, coaxial control signals are analyzed by the distortion information analysis module, the compensation degree is determined, differential control parameters are outputted to the differential module respectively, and amplitude control parameters are outputted to the amplitude control module.
