Patent ID: 8730298

Claim:
A method for switching video resolution, comprising: confirming that a video sender and a video receiver have established a video communication connection, and obtaining an initial video resolution of the video sender; confirming that bandwidth of the video communication connection and hardware of the video sender meet preset conditions, and switching the initial resolution of the video sender to a target resolution; wherein the target resolution is higher than the initial resolution; wherein confirming that the bandwidth of the video communication connection and the hardware of the video sender meet the preset conditions, comprises: confirming that the bandwidth of the video communication connection is greater than or equal to a preset value of bandwidth; confirming that a Central Processing Unit (CPU) dominant frequency of the video sender is greater than or equal to a preset value of dominant frequency; wherein confirming that the bandwidth of the video communication connection and the hardware of the video sender meet the preset conditions, further comprises: confirming that frame rate of the video sender with the initial resolution meets a preset value of the frame rate, and corresponding network packet loss rate is smaller than or equal to a preset value of the network packet loss rate.
