  • Publication number: 20160050422
    Abstract: A method of generating intra-predicted samples for a chroma channel of a video bitstream configured for a 4:2:2 chroma format. An intra-prediction angle is determined from an intra-prediction mode for the chroma channel, the intra-prediction mode being one of a plurality of horizontal intra-prediction modes. The intra-prediction angle due to the 4:2:2 chroma format is adjusted. A change threshold between the horizontal intra-prediction modes and vertical intra-prediction modes is modified if the adjusted angle exceeds a predetermined value, the modified change threshold being configured for converting the adjusted intra-prediction angle from one of the plurality of horizontal intra-prediction modes to a vertical intra-prediction mode. Intra-predicted samples are generated using a vertical intra-prediction mode according to the adjusted intra-prediction angle, and the change threshold.
