1. A wireless projection method, applied to a Wi-Fi communication system, and comprising:
transmitting, by an electronic device, a scalable video coding slice of a first video frame to a display device in a first video transmission period;
obtaining, by the electronic device, channel state information that is fed back by the display device and that is utilized for transmitting the first video frame; and
selectively enabling, based on the channel state information, the electronic device to:
transmit, a first scalable video coding slice of a second video frame to the display device in a first time period of a second video transmission period, and
transmit, to the display device in at least one other time period after the first time period, a portion of the first scalable video coding slice that is discarded in the first time period, wherein one other scalable video coding slice of the second video frame is transmitted in the at least one other time period.
