1. Postupak dekodiranja video podataka, koji predstavlja postupak koji obuhvaća:
prijem toka bitova koji se sastoji od kodiranih video podataka (2110); i
preuzimanje informacija iz toka bitova o maksimalnoj veličini jedinice za kodiranje, dijeljenju informacija o jedinici za kodiranje i informacija o vezi između dubine jedinice za kodiranje i načina kvantizacije, pri čemu informacije o danoj vezi ukazuju na način kvantizacije, za svaku dubinu između većeg broja dubina, što određuje da li se parametar kvantizacije delta treba koristiti za odgovarajuću dubinu (2120);
naznačen time da:
se slika koja odgovara kodiranim video podacima dijeli na veći broj maksimalnih jedinica za kodiranje pomoću informacija o maksimalnoj veličini jedinice za kodiranje,
maksimalna jedinica za kodiranje, između većeg broja maksimalnih jedinica za kodiranje, se hijerarhijski dijeli na jednu ili više jedinica za kodiranje s dubinama koje obuhvaćaju najmanje jednu trenutnu dubinu i manju dubinu, u skladu s podijeljenim informacijama,
dodatno uključuje, za jedinicu za kodiranje trenutne dubine:
određivanje, na osnovi informacija o navedenoj vezi, da se parametar kvantizacije delta treba koristiti u jedinici za kodiranje trenutne dubine (2130);
kada dijeljene informacije jedinice za kodiranje trenutne dubine označe dijeljenje, jedinica za kodiranje trenutne dubine se dijeli na četiri jedinice za kodiranje manje dubine, neovisno od susjednih jedinica za kodiranje, te
kada dijeljene informacije označavaju nemogućnost dijeljenja za trenutnu dubinu, nedjeljive jedinice za transformaciju se određuju iz jedinice za kodiranje trenutne dubine, inverzna kvantizacija se provodi na jedinicama za transformaciju koje koriste rezultat određivanja toga da li se parametar kvantizacije delta treba koristiti u jedinici za kodiranje trenutne dubine, a inverzna transformacija se provodi na jedinicama za transformaciju.
