Abstract

Przedmiotem wynalazku jest sposób transmisji sygnałów dźwiękowych pomiędzy nadajnikiem i co najmniej jednym odbiornikiem metodą priorytetowej transmisji pikselowej. Sygnał akustyczny jest najpierw dzielony na n części widma dźwięku. Rozłożony sygnał dźwiękowy jest zapamiętywany w dwuwymiarowej tablicy o dużej ilości pól, przy czym częstotliwość i czas określają pozycję pola w tablicy, w którym zapisuje się chwilową wartość amplitudy. Z poszczególnych pól i z co najmniej dwóch sąsiadujących pól tablicy, tworzy się grupy, którym przydziela się odpowiedni priorytet. Priorytet grupy jest tym wyższy, im większe są amplitudy wartości grup i/lub większe różnice amplitud wartości w jednej grupie i/lub im bliższa jest grupa do aktualnego czasu. W końcu grupy transmituje się do odbiornika w kolejności ich priorytetów.
