Corresponding method for encoder, decoder and chroma intra mode derivation |
| abstract |
A decoding method implemented by a decoding device, comprising: acquiring a video code stream; decoding the video code stream to obtain an initial intra prediction mode value of a chroma component of a current decoding block; determining the current decoding Whether the ratio of the width of the luminance component of the code block to the width of the chrominance component of the current decoding block is equal to a threshold; when it is determined that the ratio is equal to the threshold, according to a predefined mapping relationship and the initial intra prediction The mode value obtains the mapped intra prediction mode value of the chroma component of the current coding block; obtains the predicted sample value of the chroma component of the current coding block according to the mapped intra prediction mode value. |
