Abstract

For fleksibel signalering av en synkron modus eller en asynkron modus i flerkanalsparameterrekonstruksjonen, blir en parameterkonfigurasjonscue satt inn i datasstrømmen som blir bruk av en konfigurasjonsanordning på en flerkanaldekoderside for å konfigurere en flerkanalsrekonstruksjonsanordning. Hvis parameterkonfigurasjonscue har en første mening, vil konfigurasjonsanordningen se etter ytterligere konfigurasjonsinformasjon i sine inngangsdata, mens når parameterkonfigurasjonscue har en annen mening, vil konfigurasjonsanordningen utføre en konfigurasjonsinnstilling av flerkanalrekonstruksjonsanordningen basert på informasjonen om en kodealgoritme med hvilken overføringskanaldataene har blitt kodet, slik at det effektivt sikres på den ene side og fleksibelt på en annen side at det alltid vil oppnås en riktig tilknytning mellom parameterdataene og de dekodede overføringskanaldata.
