PCT No. PCT/EP97/03714 Sec. 371 Date Sep. 8, 1999 Sec. 102(e) Date Sep. 8, 1999 PCT Filed Jul. 8, 1997 PCT Pub. No. WO98/02966 PCT Pub. Date Jan. 22, 1998Known systems use two probability signals for coding an input signal into an output signal and for decoding said output signal into the input signal. In a first memory field two probability signals are stored, and in a second memory field two other probability signals are stored, and in response to a further received symbol processor means adapt the probability signals. Such a system needs a giant memory capacity, which can be reduced by combining probability signals into a first combination signal to be stored in the first memory field and by combining further probability signals into a second combination signal to be stored in the second memory field, and by converting a third combination signal into at least one probability signal just before (de)coding takes place.
