Abstract

Μια μέθοδος και μια συσκευή κωδικοποίησης και μια μέθοδος και μια συσκευή αποκωδικοποίησης. Στη μέθοδο κωδικοποίησης βίντεο, παράγεται μια πρώτη προβλεπόμενη μονάδα κωδικοποίησης μιας τρέχουσας μονάδας κωδικοποίησης που προορίζεται για κωδικοποίηση, παράγεται μια δεύτερη προβλεπόμενη μονάδα κωδικοποίησης με την αλλαγή μιας τιμής κάθε pixel της πρώτης προβλεπόμενης μονάδας κωδικοποίησης χρησιμοποιώντας κάθε pixel της πρώτης προβλεπόμενης μονάδας κωδικοποίησης και τουλάχιστον ένα γειτονικό pixel για κάθε pixel, και η διαφορά ανάμεσα στην τρέχουσα μονάδα κωδικοποίησης και τη δεύτερη προβλεπόμενη μονάδα κωδικοποίησης κωδικοποιείται, βελτιώνοντας έτσι την αποτελεσματικότητα της πρόβλεψης του βίντεο.
