METHOD, APPARATUS AND SYSTEM FOR ENCODING AND DECODING A TREE OF BLOCKS OF VIDEO SAMPLES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18408334 titled 'METHOD, APPARATUS AND SYSTEM FOR ENCODING AND DECODING A TREE OF BLOCKS OF VIDEO SAMPLES
Simplified Explanation
The method described in the abstract is a technique for decoding coding blocks of a coding tree unit for an image frame from a bitstream. It involves determining the chroma format of the image frame, which includes subsampled chroma channels relative to a luma channel. Based on the chroma format, the size of a chroma coding block is determined, which is collocated with corresponding luma blocks. If the size of the chroma block is above a certain threshold, it is encoded using intra prediction. The coding blocks are then decoded using intra prediction for the chroma coding block and inter prediction for at least one of the corresponding luma coding blocks.
- Determining chroma format of the image frame
- Determining size of chroma coding block based on chroma format
- Encoding chroma coding block using intra prediction if size is above threshold
- Decoding coding blocks using intra prediction for chroma and inter prediction for luma

Original Abstract Submitted
A method of decoding coding blocks of a coding tree unit for an image frame, from a bitstream. The method comprises determining a chroma format of the image frame, the chroma format having chroma channels of the image frame being subsampled relative to a luma channel of the image frame; and determining, based on the determined chroma format, a size of a chroma coding block of one of the chroma channels of the coding tree unit, wherein the chroma coding block is collocated with a plurality of corresponding luma blocks. The method comprises determining the chroma coding block is encoded using intra prediction if the determined size of the chroma block is a predetermined minimum chroma block size; and decoding the coding blocks of the coding tree using intra prediction for the chroma coding block and inter prediction for at least one of the plurality of corresponding luma coding blocks.
