Abstract
A method for decoding an image in intra prediction, includes generating two-dimensional quantized block by applying an inverse scan pattern to significant coefficients, sign flags and levels respectively; generating a quantization parameter predictor; adding the quantization parameter predictor and a differential quantization parameter to generate quantization parameter; inversely quantizing the quantized block using the quantization parameter; inversely transforming the inversely quantized block to restore a residual block; generating a prediction block; and generating a reconstructed block using the residual block and the prediction block.
