`
`AMENDMENTS TO THE CLAIMS
`
`This listing of claims will replace all prior versions andlistings of claims in the
`
`application.
`
`Listing of Claims:
`
`1.
`
`(Currently Amended) An encoder, comprising:
`
`circuitry; and
`
`memory connectedto the circuitry,
`
`wherein the circuitry, in operation,
`
`determines a modeto be applied to a block from a plurality of merge
`
`modesbased on a width of the block and a heightofthe block,
`
`when the mode determinedis a first mode, stores in a bitstream an index
`
`indicating a distance and an angle that define twopartitions in the block, and encodesthe block
`
`using the first mode, and
`
`disables the first mode and storing of the index in the bitstream when (1)
`
`the width is at least 8 times as muchasthe heightor(ii) the heightis at least 8 times as much as
`
`the width.
`
`2.
`
`(Original) The encoder according to claim 1, wherein
`
`the circuitry disables the storing of the index in the bitstream when(i) the width is
`
`64 pixels and the heightis 8 pixels or (ii) the width is 8 pixels and the heightis 64 pixels.
`
`3.
`
`(Original) The encoder according to claim 1, wherein
`
`a line that determines shapes of the two partitions in the block is defined by the
`
`distance and the angle,
`
`the distance is a distance between a center of the block and the line, and
`
`the angle is an angle related to the line.
`
`4.
`
`(Currently Amended) A decoder, comprising:
`
`circuitry; and
`
`
`
`Application No. 17/116,137

`
`memory connectedto the circuitry,
`
`wherein the circuitry, in operation,
`
`determines a modeto be applied to a block from a plurality of merge
`
`modesbased on a width of the block and a heightofthe block,
`
`when the modedeterminedis a first mode, obtains from a bitstream an
`
`index indicating a distance and an angle that define two partitions in the block, and decodes the
`
`block using the first mode, and
`
`disables the first mode and obtaining of the index from the bitstream when
`
`(i) the width is at least 8 times as muchasthe heightor(11) the height is at least 8 times as much
`
`as the width.
`
`5.
`
`(Original) The decoder according to claim 4, wherein
`
`the circuitry disables the obtaining of the index from the bitstream when(i) the
`
`width is 64 pixels and the heightis 8 pixels or(ii) the width is 8 pixels and the height is 64
`
`pixels.
`
`6.
`
`(Original) The decoder according to claim 4, wherein
`
`a line that determines shapes of the two partitions in the block is defined by the
`
`distance and the angle,
`
`the distance is a distance between a center of the block and the line, and
`
`the angle is an angle related to the line.
`
`7.
`
`(Currently Amended) An encoding method, comprising:
`
`determining a modeto be applied to a block from a plurality of merge modes
`
`based on a width of the block and a heightof the block;
`
`when the mode determinedis a first mode, storing in a bitstream an index
`
`indicating a distance and an angle that define twopartitions in the block, and encoding the block
`
`using the first mode; and
`
`disabling the first mode and the storing of the index in the bitstream when (1) the
`
`width is at least 8 times as muchasthe heightor(11) the height is at least 8 times as much as the
`
`width.
`
`
`
`Application No. 17/116,137

`
`8.
`
`(Currently Amended) A decoding method, comprising:
`
`determining a modeto be applied to a block from a plurality of merge modes
`
`based on a width of the block and a height of the block;
`
`when the mode determinedis a first mode, obtaining from a bitstream an index
`
`indicating a distance and an angle that define twopartitions in the block, and decoding the block
`
`using the first mode; and
`
`disabling the first mode and the obtaining of the index from the bitstream when(i)
`
`the width is at least 8 times as muchasthe heightor(ii) the heightis at least 8 times as much as
`
`the width.
`
`9.
`
`(New) The encoder according to claim 1, wherein,
`
`when(i) the width is at least 8 times as muchasthe heightor (11) the height is at
`
`least 8 times as muchas the width, the circuitry disables the first mode and storing of the index
`
`in the bitstream, and determines a second mode, whichis different from the first mode, as the
`
`modeto be applied to the block.
