Abstract

Official abstract text for this publication.

Disclosed decoding method of the intra prediction mode comprises the steps of: determining whether an intra prediction mode of a present prediction unit is the same as a first candidate intra prediction mode or as a second candidate intra prediction mode on the basis of 1-bit information; and determining, among said first candidate intra prediction mode and said second candidate intra prediction mode, which candidate intra prediction mode is the same as the intra prediction mode of said present prediction unit on the basis of additional 1-bit information, if the intra prediction mode of the present prediction unit is the same as at least either the first candidate intra prediction mode or the second candidate intra prediction mode, and decoding the intra prediction mode of the present prediction unit.

First claim

Opening claim text (preview).

The invention claimed is: 1. A video decoding apparatus using a quad tree structure, comprising: an entropy decoder configured to decode integrated code block flag information in an coding unit, decode a split information flag based on the integrated code block flag information and size information of a transform unit, decode a code block flag information in the transform unit in response to the transform unit not being additionally split into an additional transform unit bas…
