Claim 3:
4. An apparatus comprising:
an obtaining unit configured to:
obtain a prediction mode of a current coding unit
obtain a prediction partition mode of the current coding unit, wherein the current coding unit comprises a luma coding block and a chroma coding block, the prediction partition mode is a mode of splitting the current coding unit into prediction blocks or prediction units,
a processing unit configured to obtain a transform block of the current coding unit based on the prediction partition mode and the prediction mode; and
a reconstruction unit configured to generate a reconstructed picture block of the current coding unit based on the transform to:
when the prediction partition mode of the luma coding block is either a vertical quartering partition or a vertical asymmetric binary split, split the luma coding block through vertical the quartering partition to obtain a luma transform block, and skip splitting the chroma coding block and use the chroma coding block as a chroma transform block; or
when the prediction mode is the intra prediction mode and the prediction partition mode of the luma coding block is either a horizontal quartering partition or a horizontal asymmetric binary split, split the luma coding block through the horizontal quartering partition to obtain a luma transform block, and skip splitting the chroma coding block and use the chroma coding block as a chroma transform block; and
when the prediction mode is the inter prediction mode, skip splitting the current coding unit, and use the current coding unit as a transform unit.
