Claim:
1. A video decoding apparatus for decoding a current block comprised of a plurality of subblocks by using an intra prediction, the apparatus including a microprocessor and comprising: a prediction mode extractor, implemented by the microprocessor, configured to extract an intra prediction mode of the current block from a bitstream, without extracting intra prediction modes of respective subblocks in the current block from the bitstream; an inverse quantization unit, implemented by the microprocessor, configured to inversely quantize transformed and quantized residual subblocks corresponding to the subblocks of the current block to thereby generate transformed residual subblocks; an inverse transform unit, implemented by the microprocessor, configured to inversely transform the transformed residual subblocks to thereby reconstruct residual subblocks; and a reconstructor, implemented by the microprocessor, configured to sequentially reconstruct the subblocks by adding the predicted subblock and a residual subblock corresponding thereto,
