Abstract

En fremgangsmåte og innretning for skjuling av rammeslettinger som skyldes rammer av et omkodet lydsignal slettet under transmisjon fra en omkoder til en dekoder, og for gjenvinning av dekoderen etter rammeslettinger, innbefatter, i omkoderen, bestemmelse av skjuling/gjenvinningsparametere, inkludert i det minste faseinformasjon relatert til rammer av det omkodede lydsignal. Skjuling/gjenvinningsparameterne som er bestemt i omkoderen, transmitteres til dekoderen og i dekoderen blir rammeslettingsskjulingen gjennomført som respons på de mottatte skjuling/gjenvinningsparameterne. Rammesletting-skjulingen innbefatter resynkronisering, som respons på den mottatte faseinformasjon, av sletting-skjulte rammer med korresponderende rammer av lydsignalet som er kodet i omkoderen. Når ingen skuling/gjenvinningsparametere transmitteres til dekoderen, blir en faseinformasjon for hver ramme av det omkodede lydsignal som er slettet under transmisjon fra omkoderen til dekoderen, estimert i dekoderen. Det gjennomføres også en ramme sletting/skjuling i dekoderen som respons på den estimerte faseinformasjon, idet rammesletting-skjulingen innbefatter resynkronisering, som respons på den estimerte faseinformasjon, av hver sletting-skjulte ramme med en korresponderende ramme av lydsignalet som er kodet i omkoderen.
