description The embodiment of the invention discloses a multi-screen interaction method applied to the field of multi-screen interaction and can solve the problems of high cost, poor universality and serious delay in an existing multi-screen interaction method. The method comprises the following steps: obtaining frame data from a frame buffer by a server; performing FFmpeg conversion on the frame data by the server, and performing H.264 coding on the data subjected to FFmpeg conversion; adjusting H.264 coding parameters and sending speed through forward feedback and backward feedback by the server, wherein the forward feedback comprises adjustment of the coding parameters and the sending speed according to the data quantity of the frame buffer, and the backward feedback comprises adjustment of the coding parameters and the sending speed according to the network transmission packet loss rate.
