The present invention relates to a high-efficiency communication method facing cloud rendering. The method comprises communication of a data flow and communication of a control flow, the communication of the data flow comprises pre-rendering, capture of multimedia audio and video and audio and video decoding, and the communication of the control flow comprises capture of interaction events, playback control flow and scene rendering of a client. The high-efficiency communication method facing cloud rendering is characterized that a screen is subjected to pre-rendering through spatial prediction and time prediction based on the current state of a rendering object, a scene roaming behavior and the interaction operation behavior of a client so as to reduce the delay time when a server transmits rendering frames to a client. The server transmits the rendering frames to the client in real time, and a rendering intermediate achievement can be stored so as to avoid rendering time waste caused by rendering interruptio
