Abstract: This application provides a video transmission method and an electronic device. One example method includes: The encoder generates a video frame, where the video frame includes a plurality of image blocks, and each of the plurality of image blocks is sent within a respective specified period; and the encoder sends a target frame to a decoder if a first image block in the plurality of image blocks is not completely sent at an end moment of a corresponding specified period, where the target frame is used to request feedback information from the decoder.

Abstract: A clock synchronization method, including: obtaining (S201), by a slave clock apparatus, a first time point at which a master clock apparatus sends first information, a second time point at which the slave clock apparatus receives the first information from the master clock apparatus, a third time point at which the slave clock apparatus sends first feedback information, and a fourth time point at which the master clock apparatus receives the first feedback information from the slave clock apparatus; then obtaining (S202) a first clock count offset based on the first time point, the second time point, the third time point, and the fourth time point; then obtaining (S206) a first clock frequency offset based on the first clock count offset; and finally adjusting (S207) a clock count step of the slave clock apparatus based on the first clock frequency offset.
