Abstract

Kódoló és dekódoló eljárás több sorba kapcsolt kódoló és dekódolómodul használatával, amelynek során egy soron következő kódoló vagydekódoló modul működését azon nyomban megkezdik, amint az azt megelőzőkódoló vagy dekódoló modultól származó eredménynek egy része márrendelkezésre áll. ÓEncoding and decoding method using several encoder and decoder modules connected in series, during which the operation of a subsequent encoder or decoder module is started as soon as a part of the result from the preceding encoder or decoder module is available.
