摘要：
A coding/decoding device using a bit-precision is disclosed. A coding device includes a bit-precision selecting unit, selecting a bit-precision value according to data to be coded; and a coding unit, generating a bit-stream by coding the data according to the selected bit-precision value, whereas the selected bit-precision value is inserted into the bit-stream.With the present invention, video data can be entropy-coded by selectively determining the number of bits and there can be provided the decoding method with a little complexity which has not only the identical compression rate to the conventional entropy coding method but also no necessity of additional computation when video data is decoded.
