Abstract

Methods and apparatus for inheriting model parameters for cross-component prediction modes. According to one method, a target model parameter set associated with a target inherited prediction model is derived based on an inherited model parameter set associated with the target inherited prediction model selected from the prediction candidate list, where the target model parameter set comprises at least one re-derived or refined parameter being re-derived or refined from the inherited model parameter set, and wherein said at least one re-derived or refined parameter comprises a CCLM offset parameter when the target inherited prediction model corresponds to CCLM (Cross Component Linear Model), or two separate inherited model parameter sets are used for a second-colour block. At least one second-colour block is encoded or decoded using prediction data comprising cross-colour prediction generated by applying the target inherited prediction model with the target model parameter set to reconstructed first-colour block.
