Abstract
A method, system, and non-transitory computer readable medium is provided for decoding video data. Video data comprising a chroma component having a first nominal angle and first delta angles and a luma component having a second nominal angle and second delta angles is received, wherein the first delta angles are dependent on the second delta angles. The first delta angle values corresponding to the first delta angles are parsed or derived based at least on second delta values corresponding to the second delta angles, wherein the first delta angle values are derived from one or more nominal angles associated with one or more sample positions corresponding to one or more luma blocks. A prediction mode associated with the chroma component based on a nominal mode of a corresponding luma block is entropy-coded. The video data is decoded based on the first delta angle values corresponding to the first delta angles.
