Video encoding method and apparatus, video decoding method and apparatus, device, system, and storage medium
The present application provides a video encoding method and apparatus, a video decoding method and apparatus, a device, a system, and a storage medium. The method comprises: during prediction of a current chroma block, determining a prediction mode of the current chroma block; if the prediction mode is a cross-component intra-frame prediction mode, determining a limited range of a predicted value of the current chroma block, the limited range comprising at least one of a maximum limit value and a minimum limit value of the predicted value; then determining a first predicted value of the current chroma block on the basis of the cross-component intra-frame prediction mode; and determining a second predicted value of the current chroma block on the basis of the first predicted value and the limited range.
