1. A video decoding method, comprising:
decoding predetermined information indicating whether residual block information for a target block in an image is encoded in a bitstream or not;
determining whether the residual block information is present based on the predetermined information;
generating the target block based on an intra prediction value and the residual block information in response to the predetermined information indicating that the residual block information is present; and
generating the target block based on intra prediction using intra prediction direction information decoded from the bitstream in response to the predetermined information indicating that the residual block information is absent,
wherein the intra prediction value is generated based on a reference pixel value,
wherein the reference pixel value is determined based on a position of the target block, and
wherein 0 and 1 are values for the predetermined information to indicate whether the residual block information is encoded in the bitstream or not.
