Abstract

Μία μέθοδος αποκωδικοποίησης βίντεο περιλαμβάνει λήψη μιας ροής bit που περιλαμβάνει ένα SPS, ένα PPS και υποεικόνες που σχετίζονται με μία αντιστοίχιση ID υποεικόνας. Γίνεται καθορισμός εάν μία σημαία SPS έχει μία πρώτη ή μία δεύτερη τιμή. Η σημαία PPS που έχει την πρώτη τιμή εξειδικεύει ότι η αντιστοίχιση ID υποεικόνας σηματοδοτείται στο SPS, και η δεύτερη τιμή εξειδικεύει ότι η αντιστοίχιση ID υποεικόνας σηματοδοτείται στο PPS. Η αντιστοίχιση ID υποεικόνας λαμβάνεται από το SPS όταν η σημαία SPS έχει την πρώτη τιμή και από το PPS όταν η σημαία SPS έχει τη δεύτερη τιμή ή η σημαία PPS έχει την πρώτη τιμή.
