A decoder decodes a bitstream of a video and determines decoding parameters of a current picture in the video; determines, 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; determines decoded data based on the reconstructed data of the first picture component and the reconstructed data of the second picture component. An encoder determines identification information of a current picture in a video; codes reconstructed data of a first picture component; the encoder skips encoding of the reconstructed data of the second picture component, in response to the identification information indicating using the prediction model for determining the reconstructed data of the second picture component; and signals coded bits into a bitstream of the video.
