Abstract

Fremgangsmåter og verktøy for selektiv bruk av flere entropimodeller ved adaptiv koding og dekoding er beskrevet her. For flere symboler kan en lydinnkoder for eksempel velge en entropimodell fra et første sett av modeller som omfatter flere entropimodeller. Hver av de flere entropimodellene omfatter et modellskiftepunkt for å skifte til et andre sett av modeller som omfatter én eller flere entropimodeller. Innkoderen behandler de flere symbolene ved anvendelse av den valgte entropimodellen og mater ut resultater. Fremgangsmåter og verktøy for å generere entropimodeller er også beskrevet.
