Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. The video encoding method, comprising:
generating predetermined information indicating whether residual block information is encoded in a bitstream or not;
generating a target block based on an intra prediction value and a residual block corresponding the residual block information when the predetermined information indicates that the residual block information is present; and
generating the target block based on intra prediction using an intra prediction direction when the predetermined information indicates that the residual block information is absent, wherein:
intra prediction direction information in the bitstream indicates the intra prediction direction,
the intra prediction value is generated based on a reference pixel value,
the reference pixel value is determined based on a position of the target block, and
0 and 1 are values for the predetermined information to indicate whether the residual block information is encoded in the bitstream or not.
