    摘要: A decoding method including receiving a bitstream corresponding to a residual block, decoding the residual block having a plurality of residual pixels represented as transform coefficients, and computing a reconstructed block based on the residual pixels. The reconstructed block includes reconstructed pixels and uses an intra prediction mode to generate prediction pixels in sequence vertically or horizontally based on reconstructed pixels in the reconstructed block. The reconstructed block includes initial reconstructed pixels based on initial prediction pixels. The intra prediction mode is used to generate the initial prediction pixels based on external reference pixels located in neighboring blocks decoded before the reconstructed block. Computing the reconstructed block includes combining prediction pixels with residual pixels to generate additional reconstructed pixels used to generate additional prediction pixels. The additional prediction pixels are located in one position before each the additional prediction pixels according to a prediction order of the intra prediction mode.
