Abstract: Before a network jitter occurs, a server receives operation instructions from an electronic device, generates a plurality of first rendering instruction streams based on the operation instructions, sends the plurality of first rendering instruction streams to the electronic device, and generates and stores one or more first rendering contexts for one or more first rendering instruction streams in the plurality of first rendering instruction streams. When the network jitter occurs, the server generates a second rendering instruction stream based on received operation instructions, and generates and stores a second rendering context based on the second rendering instruction stream. After the recovery from the network jitter, the server sends a set of rendering context differences to the electronic device. In this way, network transmission traffic after the recovery from the network jitter is reduced, transmission and processing delays are also reduced, and user experience is improved.
