The present application relates to a wireless screen sharing method, device, system and intelligent interactive tablet. The method includes: acquiring the input frame rate and decoding frame rate of the screen transmission image at the receiving end; comparing the input frame rate and the decoding frame rate; determining the target input frame rate of the receiving end according to the comparison result; according to the target input frame rate and sending According to the number of terminals, a corresponding adjustment command is generated; an adjustment command is sent to the sender, and the adjustment command is used to adjust the encoding frame rate of the transmission screen image at the sender. Using this method can make the encoding frame rate of the transmission screen image at the sending end adaptively change and adjust according to the decoding ability of the receiving end, thereby ensuring that the image quality finally presented by the receiving end is high, and reducing or avoiding the appearance of the image after wireless screen transmission Distortion or freezing, to meet user needs.
Description
technical field [0001] The present application relates to the field of wireless screen transmission, in particular to a wireless screen transmission method, device, system and intelligent interactive panel. Background technique [0002] Wireless screen transfer technology is used to synchronize the information displayed on the screen of source devices such as mobile phones and computers to receivers such as projectors, TVs or conference panels for display through WIFI or other wireless communication methods. At present, the implementation process of wireless screen transfer is mostly: obtain the screen image to be synchronized on the source device, encode the screen image according to the set frame rate; pack the encoded data into a data packet, and transmit it to the transmission medium; The transmission medium sends the data packet to the receiving end; the receiving end unpacks and decodes the data packet according to the set frame rate, and finally displays it. [0003]...
