Abstract
A wireless screen transmission method, an extension device, and a wireless screen transmission system are disclosed. The wireless screen transmission method includes: receiving screen display data and audio data captured by a source end device; transmitting the screen display data and the audio data to a touch screen display end over a wireless network, so that the screen display data and the audio data are presented by the touch screen display end; receiving touch data generated by the touch screen display end over the wireless network; and transmitting the touch data to the source end device, so that an operation corresponding to the touch data is performed by the source end device. The present invention further implements returning of touch data from a display end in a wireless manner based on wireless screen transmission, thereby improving flexibility and convenience of operations.
