WIRELESS PROJECTION METHOD AND APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18343141 Titled 'WIRELESS PROJECTION METHOD AND APPARATUS'
Simplified Explanation
This application presents a wireless projection method and device that aim to enhance the user experience by addressing issues such as image tearing, freezing, and deterioration in image quality that commonly occur in wireless projection. The method is specifically designed for Wi-Fi communication systems. It involves transmitting a portion of a video frame, known as a scalable video coding slice, from an electronic device to a display device during a specific video transmission period. The electronic device then receives channel state information from the display device, which is used to determine whether to activate a retry mechanism for transmitting the video frame. Overall, this method aims to improve the wireless projection experience by reducing image issues and optimizing the transmission process.
Original Abstract Submitted
Embodiments of this application provide a wireless projection method and apparatus, and relate to the communication field, to reduce image tearing and freezing and image quality deterioration occurring in wireless projection, and improve user experience. The wireless projection method is applied to a Wi-Fi communication system, and includes: An electronic device transmits a scalable video coding slice of a first video frame to a display device in a first video transmission period; obtains channel state information that is fed back by the display device and that is for transmitting the first video frame; and selectively enables a retry mechanism based on the channel state information.
