Abstract
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.
