a modification unit to determine {TAIL ~ a modified first arithmetically coded portion} such that the second coded portion is decodable to produce a common result based on either an output from decoding the first coded portion or an output from decoding the modified first arithmetically coded portion, wherein {HEAD ~ the modification unit} determines a modified first arithmetically coded portion that generates a Context based Adaptive Binary Arithmetic Coding state value that is the same as a CABAC state value generated by the first coded portion
