摘要 |
Known 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 memor y 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 fie ld and by combining further probability signals into a second combination signa l to be stored in the second memory field, and by converting a third combinati on signal into at least one probability signal just before (de)coding takes pla ce.
