Abstract
An image encoding and decoding method includes obtaining a to-be-encoded image, where the to-be-encoded image is divided into a base layer and at least one enhancement layer; when feedback information sent by a decoder side is received, determining a reconstructed image corresponding to a frame sequence number and a layer sequence number indicated in the feedback information as a first reference frame, and performing inter encoding on the base layer based on the first reference frame to obtain a bitstream of the base layer; encoding the at least one enhancement layer to obtain a bitstream of the at least one enhancement layer; and sending the bitstream of the base layer and the bitstream of the at least one enhancement layer to the decoder side, where the bitstream of the base layer carries coding reference information.
