`
`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 isatleast8+imes-as-much-aso64 pixels and the heightis 8 pixels or (ii) the height is 64
`
`
`
`pixels andatleast8+times-asmuchas-the width is 8 pixels.
`
`2.
`
`3.
`
`(Canceled)
`
`(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
`
`memory connectedto the circuitry,
`
`wherein the circuitry, in operation,
`
`
`
`Application No. 17/116,137
`Reply to Office Action Dated October 14, 2021
`
`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 64 pixels andatleast8+mes-as4much-as-the height is 8 pixels or (11) the height is
`
`
`
`64 pixels andatleast8-+times-asmuch-as-the width is 8 pixels.
`
`5.
`
`6.
`
`(Canceled)
`
`(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 isatleast8+times-as-much-as64 pixels and the heightis 8 pixels or (ii) the height is 64
`
`
`
`pixels andatleast8+times-asmuchasthe width is 8 pixels.
`
`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 heightof the block;
`
`
`
`Application No. 17/116,137
`Reply to Office Action Dated October 14, 2021
`
`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 64 pixels andatleast8+imes-as-much-asthe height is 8 pixels or (11) the height is 64
`
`
`
`pixels andatteast8+times-asmuchas-the width is 8 pixels.
`
`9.
`
`(Currently Amended) The encoder according to claim 1, wherein,
`
`
`
`when(i) the width isatleast8-times-asmuch-aso4 pixels and the heightis 8 pixels
`
`
`
`or(ii) the height is 64 pixels andatteast8+times-asmueh-asthe width is 8 pixels, 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 mode to be applied to the block.
