ENCODER, ENCODING METHOD, DECODER, AND DECODING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18530032 titled 'ENCODER, ENCODING METHOD, DECODER, AND DECODING METHOD

Simplified Explanation

The encoder described in the patent application determines whether a ternary split process is allowed, splits a block into sub-blocks based on the split direction parameter, and encodes the sub-blocks.

• The circuitry in the encoder compares the size of the second shorter side of the block to a minimum threshold value to determine if a ternary split process is allowed.
• If the ternary split process is allowed, the encoder writes a split direction parameter into a bitstream indicating the splitting direction.
• The block is then split into multiple sub-blocks in the direction indicated by the split direction parameter, and the encoder encodes these sub-blocks.
• The minimum threshold value corresponds to the minimum size supported in a transform process.

Original Abstract Submitted

An encoder includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, determines whether or not a ternary split process of splitting a block into three sub blocks in a first direction parallel to a first longer side of the block is allowed by comparing a size of a second shorter side of the block to a minimum threshold value. The circuitry, responsive to the ternary split process being allowed, writes, into a bitstream, a split direction parameter indicative of a splitting direction. The circuitry, in operation, splits the block into a plurality of sub blocks in a direction indicated by the split direction parameter; and encodes the plurality of sub blocks. The minimum threshold value corresponds to a minimum size supported in a transform process.
