Abstract
A data streaming method includes determining M key frames in a target group of pictures GOP, where the target GOP includes L frames, M is an integer greater than 0, and L is an integer greater than 2. Scalable encoding is performed on source data of each of the M key frames to generate M pieces of base layer data and N pieces of extension layer data, where data quality of extension layer data corresponding to each key frame is higher than data quality of base layer data corresponding to each key frame, and N is an integer greater than or equal to M. Differential protection is performed on the base layer data and the extension layer data of each key frame to obtain first encoded data of the M key frames.
