Abstract
An encoding method of an image block is disclosed. The image block to be encoded is first partitioned in at least two partitions, wherein one of said at least two partitions is an L-shaped partition. Each partition is then encoded in encoded data.
Claims24
An encoding method comprising:
- partitioning a current block to be encoded using intra prediction sub-partition (ISP) mode into at least two partitions, wherein one of the at least two partitions is a L-shaped partition;
- and
- encoding the current block by encoding each of the at least two partitions with an intra prediction mode associated with the current block.

11-13. (canceled)
A decoding method comprising:
- obtaining encoded data for a current block to be decoded using intra prediction sub-partition (ISP) mode into at least two partitions, wherein one of the at least two partitions is a L-shaped partition;
- and
- decoding the current block by decoding each of the at least two partitions from the encoded data with an intra prediction mode associated with the current block.

24-30. (canceled)
An encoding apparatus comprising one or more processors and at least one memory coupled to the one or more processors, wherein the one or more processors are configured to perform:
- partitioning a current block to be encoded using intra prediction sub-partition (ISP) mode into at least two partitions, wherein one of the at least two partitions is a L-shaped partition;
- and
- encoding the current block by encoding each of the at least two partitions with an intra prediction mode associated with the current block.
