1. A video encoding method using a bitstream comprising:
generating a prediction block for a current block by performing prediction for the current block; and
generating transformed and quantized residual block information based on a residual block which is generated using the prediction block for the current block,
wherein for decoding for the current block using the transformed and quantized residual block information, a first prediction block for the current block is generated based on a prediction block generation method for the current block,
wherein for the decoding for the current block, the prediction block generation method for the current block is determined based on a plurality of prediction block generation methods for a plurality of adjacent blocks which are spatially adjacent to the current block,
wherein for the decoding for the current block, the plurality of the prediction block generation methods for the plurality of the adjacent blocks are used to generate a plurality of second prediction blocks for the plurality of the adjacent blocks, respectively,
wherein for the decoding for the current block, the prediction block generation method for the current block is determined based on the number of one or more different values of the plurality of the prediction block generation methods for the plurality of the adjacent blocks,
wherein the first prediction block for the current block is equal to a specific decoded block indicated by difference information,
wherein the bitstream comprising the difference information is generated,
wherein the difference information indicates a position difference from a position of the current block to a position of the specific decoded block,
wherein a size of the first prediction block is 16×16, and
wherein a size of the specific decoded block is 16×16.
