Abstract: A screen recording method computes an encoding delay for each frame of a screen of an electronic device. The frame is encoded by a first compression algorithm if the encoding delay is short. The frame is encoded by an second compression algorithm if the encoding delay is middle and a time interval between the encoding time of a previous frame and the encoding time of a current frame does not exceed a first preset time interval. The frame is encoded by a third compression algorithm if the encoding delay is long and a time interval between the encoding time of a previous frame and the encoding time of a current frame exceeds a second preset time interval.

Abstract: A server communicates with at least one client. If the server wants to transmit streaming media to a client, the client sends a package to the server. The package indicates if the client can decode the streaming media. If the client can decode the streaming media, the server decodes the streaming media and outputs the decoded streaming media on a display of the server. The server sends the streaming media to the client. The client decodes the streaming media and outputs the decoded streaming media on a display of the client. If the client cannot decode the streaming media, the server obtains the streaming media on the desktop of the server and compresses the streaming media to a compressed file. The client receives the compressed file from the server, and decompresses the compressed file. The decompressed files are output on the display of the client.
