Abstract

Et bildeområde oppfrlskes under transmissjonen av et sett av bevegelseskompenserte sekvensielle videobilder. Videobildene oppdeles l et flertall av hosliggende regioner. Blldeområdet oppfrlskes under en oppfrlsk- nlngssyklus ved å kommunisere en forskjellig region l hvert suksessive videobilde av settet uten bevegelses- kompensering. Bevegelseskompenserlng av de tidligere oppfriskede regioner av blldeområdet under oppfrisk- nlngssyklusen er begrenset til et område som inneholder kun de tidligere oppfriskede regioner. Videobildedata fra en eksisterende region som oppfrlskes blir kodet for bruk ved hjelp av en dekoder (figur 2) for å identifisere nevnte data som ikke-bevegelseskompensert data.
