摘要：
Provided are a method and apparatus of a lossless encoding and decoding based on a context. According to an embodiment, by aligning and coding symbols of a MSB, a coding efficiency may be enhanced. According to an embodiment, by estimating initial scaling information using a symbol located proximate to a symbol of the MSB, the coding efficiency may be enhanced.
