- Abstract
- A video decoding apparatus according to the present invention includes an entropy decoding module for performing entropy decoding on an input bit stream to derive a quantized transform coefficient associated with a target decoding unit, an inverse quantization module for transforming the quantized transform coefficients Performing an inverse quantization to derive a transform coefficient; an inverse transform module for performing inverse transform on the transform coefficients to generate a residual block; a prediction module for deriving adjacent lines from the left adjacent prediction mode and the adjacent prediction mode Prediction mode information for deriving an intra prediction mode for the target decoding unit by using the derived adjacent prediction mode information and performing intra prediction on the target decoding unit based on the derived intra prediction mode; an adder for adding The residual block being added to a prediction block generated by intra prediction to generate a reconstruction block; and a filtering module for performing filtering on the reconstruction block.
