Classification: CPC H | IPC H

Claim 10:
11. A video encoding apparatus, comprising:
an entropy encoder encoding predetermined information indicating whether residual block information for a residual block is encoded in a bitstream or not; and
a predictor determining whether the residual block is used to generate a target block or not, wherein:
the predictor generates the target block based on an intra prediction value and the residual block for the target block when the predetermined information indicates that the residual block information is present,
the entropy encoder performs entropy encoding for intra prediction direction information indicating an intra prediction direction to generate entropy-encoded intra prediction direction information in the bitstream for the target block,
the predictor generates the target block based on the intra prediction direction when the predetermined information indicates that the residual block information is absent,
the intra prediction value is generated based on intra prediction using a reference pixel value, and
0 and 1 are values for the predetermined information to indicate whether the residual block information is encoded in the bitstream or not.
