Abstract
Official abstract text for this publication.
A reconstructed block creating method in a decoder can include obtaining an intra prediction mode group indicator and a prediction mode index from a received bitstream; decoding an intra prediction mode using the intra prediction mode group indicator, the prediction mode index and a MPM group, in which the MPM group is generated using intra prediction modes of left and top blocks of a current block, and the MPM group includes three intra prediction modes; constructing a prediction block using the intra prediction mode and reference pixels; inversely quantizing a received residual signal using a quantization parameter to create a quantized block and inversely transforming the quantized block to create a residual block; and adding the prediction block and the residual block to create a reconstructed block.
First claim
Opening claim text (preview).
What is claimed is: 1. A reconstructed block creating method in a decoder, the method comprising: obtaining an intra prediction mode group indicator and a prediction mode index from a received bitstream; decoding an intra prediction mode using the intra prediction mode group indicator, the prediction mode index and a most probable mode (MPM) group, wherein the MPM group is generated using intra prediction modes of left and top blocks of a current block, and the MPM group include…
