Outputs of this process are the initialised decoding engine registers codIRange and codIOffset both in 16 bit register precision. The status of the arithmetic decoding engine is represented by the variables codIRange and codIOffset. In the initialisation procedure of the arithmetic decoding process, codIRange is set equal to 510 and codIOffset is set equal to the value returned from interpreted as a 9 bit binary representatio
