Abstract
Official abstract text for this publication.
Disclosed is a high-resolution video encoding/decoding method and apparatus. The video encoding method includes: predicting a current block to generate a predicted block, subtracting the predicted block from the current block to generate a residual block, determining a transform and quantization type according to the block type of the current block; transforming and quantizing the residual block according to the determined transform and quantization type; and encoding the transformed and quantized residual block. According to the video encoding/decoding method and apparatus, not only the encoding efficiency can be improved because it enables an encoding using a high correlation between temporally/spatially adjacent pixels appearing in a video, but the compression efficiency can also be improved by reducing block distortion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A video decoding method for decoding video data obtained by dividing an input video into a plurality of macroblocks having various sizes and encoding each of the macroblocks, the method comprising: decoding macroblock information indicating the size of each of the macroblocks; and decoding a macroblock based on the macroblock information, wherein, when the macroblock is intra-predicted, the decoding of the macroblock comprises: decoding macroblock…
