INTRA PREDICTION METHOD AND DEVICE FOR A VIDEO SEQUENCE Russian patent published in 2023 - IPC H04N19/593 H04N19/186 H04N19/103 

FIELD: video coding and decoding technologies.

SUBSTANCE: invention relates to an intra prediction method. An intra prediction method for a video sequence is proposed. The method includes: obtaining a size and splitting mode of a chroma coding tree node; determining, based on the size and splitting mode of the chrominance coding tree node, as to whether to allow performing cross-component linear model (CCLM) intra prediction on a chroma coding unit included in the chrominance coding tree node; determining a chroma coding unit prediction mode depending on whether CCLM is allowed to be performed on the chroma coding unit; and processing a chroma coding unit based on the chroma coding unit prediction mode to obtain chroma coding unit prediction samples.

EFFECT: reducing the delay in processing a chroma coding unit and increasing the throughput of a hardware decoder.
