1. A decoding method, applied to a decoder, the method comprising:
decoding a bitstream of a video and determining decoding parameters of a current picture in the video, wherein the decoding parameters of the current picture comprises reconstructed data of a first picture component of one or more pictures in the video;
determining, according to the decoding parameters of the current picture, reconstructed data of a second picture component of the current picture based on the reconstructed data of the first picture component by using a prediction model, wherein the second picture component differs from the first picture component; and
determining decoded data of the current picture based on the reconstructed data of the first picture component and the reconstructed data of the second picture component of the current picture,
wherein the decoding parameters of the current picture further comprise identification information, wherein the identification information indicates whether to use the prediction model for determining the reconstructed data of the second picture component.
