Claim 17:
18. The non-transitory computer-readable storage medium of claim 15, wherein the determining the context model index ctxInc of a flag of the current block further comprises:
if the flag of the current block is qt_split_flag, a picture region in which the current block is located is an I slice or an I frame, and a width of the current block is th4, determining that a value of the context model index ctxInc used by the flag qt_split_flag is 3, wherein the obtained size information of the current block comprises the width of the current block and a height of the current block, wherein the flag qt_split_flag is used to indicate whether quadtree split is used for the current block; or
if the flag of the current block is split_dir, the width of the current block corresponding to a current to-be-split node is a threshold th5, and the height of the current block is greater than the threshold th5, determining that the value of the context model index ctxInc used by the flag split_dir is 3; or
if the flag of the current block is split_dir, the height of the current block corresponding to a current to-be-split node is the threshold th5, and the width of the current block is greater than the threshold th5, determining that the value of the context model index ctxInc used by the flag split_dir is 4, wherein the obtained size information of the current block comprises the width of the current block and the height of the current block, wherein the flag split_dir is used to indicate a split direction of the current block.
