The invention discloses a time sequence configurable multi-channel dynamic video simulation method and a processing system thereof. The system comprises an interface module, a video decoding module, an RGB/YCbCr data caching module, a data writing module, a memory time sequence control module, a data reading module, an output data caching module, a time sequence generation module, a protocol generation module and an output interface module which are sequentially connected; the control interface module is connected with the time sequence generation module through a control command analysis module. According to the invention, any customized dynamic video can be received; According to the invention, multiple paths of dynamic video images are independently output, the frame frequency, resolution and time sequence characteristics of the dynamic video images can be independently adjusted on line, any video can be converted into multiple paths of dynamic videos with different frame frequencies, resolutions and time sequence characteristics, the research and development cost of image processing equipment is reduced, and the research and development cost of matched products is reduced; Thebatch production capability of the image processing equipment is improved, simultaneous debugging and testing of a plurality of image processing equipment are met, and the production period is shortened.
