1. A method for transmitting video data, applied to a chip for substrate management control, wherein the method for transmitting the video data comprises:
compressing the video data sent by a host end to obtain video compression data, and respectively storing the video compression data into a first storage space and a second storage space according to a ping-pong operation structure, so that the first storage space stores video compression data of odd frames, and the second storage space stores video compression data of even frames;
when a data transmission instruction is received, reading first data to be transmitted with a preset byte length from the first storage space, and reading second data to be transmitted with the preset byte length from the second storage space;
determining whether a similarity between the first data to be transmitted and the second data to be transmitted is greater than or equal to a preset value;
when the similarity between the first data to be transmitted and the second data to be transmitted is greater than or equal to the preset value, setting the first data to be transmitted added with a first transmission identifier as current frame data, and setting a second transmission identifier corresponding to the first transmission identifier as next frame data; and
sending the current frame data and the next frame data to a video data receiving end.
