Abstract
Embodiments of this application provide for a wireless projection method and apparatus. The embodiments relate to the communication field and reduce an occurrence of image tearing and freezing and image quality deterioration during wireless projection to improve a user's experience. The wireless projection method is applied to a Wi-Fi communication system. In the method, an electronic device transmits a scalable video coding slice of a first video frame to a display device in a first video transmission period. The method also includes obtaining channel state information that is fed back by the display device and that is used for transmitting the first video frame. The method also includes selectively enabling a retry mechanism based on the channel state information.
