The pixel change-picture transmission quality curve can be explained as a curve in which the picture transmission quality curve changes with the pixel change value.
In the embodiment of the present invention, the pixel change calculation formula is as follows:

and identifying picture transmission quality coordinate points of the target video frames in the time-picture transmission quality curve according to the measured time of the target video frames.

By comparing the picture transmission quality represented by the pixel change-picture transmission quality curves of the ICA protocol and the Spice protocol at the same time, the optimal transmission protocol corresponding to different pixel change values is searched. For example: the whole measurement time is 10:00-11:00, and 10:00-10: in the 10 time period, the ICA protocol is larger than the pixel change-picture transmission quality curve value corresponding to the Spice protocol, and then 10:00-10: the pixel change value within the 10 time period is suitable for picture transmission using ICA protocol.

The current cloud desktop frame to be transmitted refers to a certain video frame in the cloud desktop video frame set to be transmitted.
And S8, judging whether the current cloud desktop frame to be transmitted is a video frame or not.
In the embodiment of the invention, the determination can be made by determining whether the frame rate of the video frame where the cloud desktop frame to be transmitted is currently located is greater than 20 frames/s, and if the frame rate of the video frame is greater than 20 frames/s, the video frame is indicated to be the video frame, otherwise, the video frame is not indicated to be the video frame.
And if the current cloud desktop frame to be transmitted is not the video frame, executing S9, transmitting the cloud desktop picture by utilizing the Spice protocol, and measuring the picture transmission quality.
Further, the alice protocol is applicable to an office environment, so that when the cloud desktop frame to be currently transmitted is not a video frame, the alice protocol is used by default.
And if the current cloud desktop frame to be transmitted is a video frame, executing S10, and calculating a current pixel change value of the current cloud desktop frame to be transmitted.

It can be understood that the PCoIP protocol refers to a PC over IP protocol, and since the PCoIP protocol is more suitable for use in a low bandwidth network, the PCoIP protocol can be used when the picture transmission quality is always disqualified.
And if the transmission quality of the current picture is qualified, returning to the step of acquiring the current cloud desktop frame to be transmitted, and finishing the android-based cloud desktop connection multi-protocol automatic switching method.
