Abstract
Discussed are a method and an apparatus of encoding/decoding by using a bit precision. In accordance to an aspect of the present invention, it is possible to encoding and decoding an image or a video by using a bit precision. Accordingly, compression efficiency can be improved and the decoding complexity can be reduced by encoding/decoding video data by use of the bit precision.
