RECORDED MEDIUM HAVING PROGRAM FOR CODING AND DECODING USING BIT-PRECISION, AND APPARATUS THEREOF

摘要

A coding/decoding device using a bit-precision is disclosed. A coding device includes a bit-precision selecting unit, which selects a bit-precision value according to data to be coded; and a coding unit, which generates 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 while the compression rate of the conventional entropy coding method is mostly maintained, the present invention is much less complicated because no additional computation is needed when video data is decoded.
