And it defines intra, IBC, and inter coding modes can be used for MODE_TYPE_ALL. However, palette mode (MODE_PLT) should be used for MODE_TYPE_INTRA and MODE_TYPE_ALL as well. It is suggested to make the following changes to section 6.4.1, 6.4.2, and 6.4.3 to include palette for MODE_TYPE_INTRA and MODE_TYPE_ALL. Additionally, furthermore, it is suggested to rename “MODE_TYPE_INTRA” to “MODE_TYPE_NON_INTER” to better align its intent. '''6.4.1 Allowed quad split process''' Inputs to this process are: – a coding block size cbSize in luma samples, – a multi-type tree depth mttDepth, – a variable treeType specifying whether a single tree (SINGLE_TREE) or a dual tree is used to partition the coding tree node and, when a dual tree is used, whether the luma (DUAL_TREE_LUMA) or chroma components (DUAL_TREE_CHROMA) are currently processed, – a variable modeType specifying whether intra (MODE_INTRA), IBC (MODE_IBC), '''palette (MODE_PLT)''' and inter coding modes can be used (MODE_TYPE_ALL), or whether only intra, IBC '''and palette''' coding modes can be used (MODE_TYPE_INTRA), or whether only inter coding modes can be used (MODE_TYPE_INTER) for coding units inside the coding tree node. … 6.4.2 Allowed binary split process Inputs to this process are: – … – a variable treeType specifying whether a single tree (SINGLE_TREE) or a dual tree is used to partition the coding tree node and, when a dual tree is used, whether the luma (DUAL_TREE_LUMA) or chroma components (DUAL_TREE_CHROMA) are currently processed, – a variable modeType specifying whether intra (MODE_INTRA), IBC (MODE_IBC), '''palette (MODE_PLT)''' and inter coding modes can be used (MODE_TYPE_ALL), or whether only intra, IBC '''and palette''' coding modes can be used (MODE_TYPE_INTRA), or whether only inter coding modes can be used (MODE_TYPE_INTER) for coding units inside the coding tree node. …. 6.4.3 Allowed ternary split process Inputs to this process are: – … – a variable treeType specifying whether a single tree (SINGLE_TREE) or a dual tree is used to partition the coding tree node and, when a dual tree is used, whether the luma (DUAL_TREE_LUMA) or chroma components (DUAL_TREE_CHROMA) are currently processed, – a variable modeType specifying whether intra (MODE_INTRA), IBC (MODE_IBC), '''palette (MODE_PLT)''' and inter coding modes can be used (MODE_TYPE_ALL), or whether only intra, IBC '''and palette''' coding modes can be used (MODE_TYPE_INTRA), or whether only inter coding modes can be used (MODE_TYPE_INTER) for coding units inside the coding tree node. … ",defect,closed,blocker,VVC D10,spec,VVC D9 vB,fixed,,ksuehring bbross XiangLi fbossen jvet@…
