Video Encoding/Decoding Method and Apparatrus in Consideration of Low Frequency Component

The present invention relates to a video encoding / decoding method and apparatus taking into account the low-frequency components. Characterized in that the present invention is to produce an image data coding by prediction coding the current block and generates a restored block, generating a low-frequency data encoded by encoding only the low frequency component of the error block generated by subtracting the current block and the restored block It provides a video coding method. According to the present invention, it is possible to reduce the blocking effect by the transform and quantization, while improving the coding efficiency as the coding of the video in consideration of the low-frequency components.
