Abstract: This application provides encoding and decoding methods and apparatuses for an enhancement layer. The encoding method includes: an encoder obtains a reconstructed block of a base layer of a to-be-encoded picture block; calculates a difference between corresponding pixels in the to-be-encoded picture block and the reconstructed block of the base layer to obtain a residual block of an enhancement layer of the to-be-encoded picture block; determines a transform-block partitioning manner of the residual block of the enhancement layer; and performs transformation on the residual block of the enhancement layer based on the transform-block partitioning manner. This application can simplify a processing procedure for the encoder and improve encoding efficiency of the encoder. In addition, compression efficiency of the residual block can be improved more effectively by using an adaptive TU partitioning method.

Abstract: The technology of this application relates to an encoding method, an encapsulation method, a display method, an apparatus, and an electronic device. The encoding method includes obtaining a to-be-encoded image, determining N encoding scales (N is an integer greater than 1) for the image, determining an encoding parameter corresponding to each of the N encoding scales, to obtain N groups of encoding parameters, and encoding the image N times by using a preset single-scale encoder based on the N groups of encoding parameters to obtain N groups of bitstream data. In this way, the image is encoded to obtain the bitstream data with a small data amount (namely, the bitstream data with a low encoding scale), so that when a network fluctuates, the bitstream data corresponding to the image can arrive at a decoder side with a higher probability, thereby ensuring smoothness of video playing.
