1. Postupak za dekodiranje video zapisa, te postupak sadrži slijedeće:
dobivanje, iz toka bitova, informacije o tipu korekcije vrijednosti piksela;
kada informacija o tipu korekcije vrijednosti piksela označava jedan od pojasnog tipa i rubnog tipa, dobivanje kompenzacijske vrijednosti iz toka bitova;
naznačen time da:
kada informacija o tipu korekcije vrijednosti piksela označava pojasni tip, dodavanje kompenzacijske vrijednosti pikselu u pojasu između piksela trenutnog bloka, pri čemu ukupan raspon vrijednosti piksela je jednoliko podijeljen u mnoštvo pojaseva, te je pojas jedan od mnoštva pojaseva, vrijednost piksela je u rasponu vrijednosti piksela koje odgovaraju pojasu, te kompenzacijska vrijednost odgovara pojasu između mnoštva pojaseva; i
kada informacija o tipu korekcije vrijednosti piksela označava rubni tip, dodavanje kompenzacijske vrijednosti pikselu koji odgovara razini rubne vrijednosti između piksela trenutnog bloka, pri čemu se razina rubne vrijednosti određuje na temelju toga da li je vrijednost piksela (30) veća ili manja od vrijednosti susjednih obnovljenih piksela (31. 32, 33, 34, 35, 36, 37 i 38) u okomitom, vodoravnom ili dijagonalnom smjeru, te vrijednost kompenzacije odgovara razini rubne vrijednosti između mnoštva razina graničnih vrijednosti.
