  • Publication number: 20250030874
    Abstract: A method is disclosed for predicting chroma components based on reconstructed luma information. In the disclosed embodiments, to intra-predict the current chroma block, the video decoding device decodes the prediction mode indicator of the current chroma block and checks whether the prediction mode indicator utilizes the Direct Mode_Intra Block Copy mode (DM_IBC mode) for the current chroma block. If the current chroma block utilizes DM_IBC mode, the video decoding device uses the block vector of the previously reconstructed corresponding luma block to generate the prediction block of the current chroma block.
