Abstract

The invention relates to a wireless screen projection method, and a wireless screen projector and a conference system suitable for the wireless screen projection method. The wireless screen projectionmethod comprises the following steps: establishing communication connection with source equipment through a plug-and-play interface so as to display a preset storage space of the wireless screen projector to the source equipment and establish an HID channel between the wireless screen projector and the source equipment; loading the screen capture application program to the source equipment so asto run the screen capture application program on an operating system of the source equipment to perform screen capture operation to obtain screen projection picture data; automatically running the automatic screen projection application program to enable the energy equipment to transmit screen projection picture data through the HID channel; and receiving the screen projection picture data transmitted through the HID channel and sending the screen projection picture data to the display device in a wireless mode. According to the embodiment of the invention, a plug-and-play automatic screen projection starting mode is adopted, so that the screen projector does not need to be provided with a physical key, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of data transmission and display, in particular to a wireless screen projection method, a wireless screen projection device and a conference system. Background technique [0002] In related technologies, displaying content on one screen to another screen is called screen projection. Screen projection technology is widely used in work conferences, video education, home theaters, and other occasions. Based on screen projection technology, the media data played and displayed in the source device can be transmitted to the display screen of the display device for synchronous playback and display; the source device refers to the device that projects the media data to the display device for synchronous playback and display, such as a desktop Desktop computer, notebook computer, mobile terminal, etc. At present, screen projection technology is divided into wired screen projection technology and wireless screen proj...
