The system may include a bitrate adaptation unit determining a maximum length of a prefix using a compression bitrate of the video data, a binarization unit dividing the video data into a prefix and a suffix according to the determined maximum length of the prefix and binarizing the video data, and an arithmetic encoding unit performing an arithmetic encoding on the binarized video data. The video data may be encoded/decoded using binary arithmetic encoding/decoding by determining the maximum length of the prefix, an order of an exponential Golomb code, and the number of contexts based on the compression bitrate. Accordingly, it is possible to obtain high encoding efficiency regardless of a range of the desired compression bitrate.
