Abstract
Οι ενσωματώσεις της παρούσας εφεύρεσης παρέχουν μία μέθοδο κωδικοποίησης ή αποκωδικοποίησης και μία διάταξη. Η μέθοδος περιλαμβάνει: την εξαγωγή των πρώτων πληροφοριών σε μία δυφιορρευματική τεχνική (bitstream), τον προσδιορισμό ενός τρόπου λειτουργίας ενδο-πρόβλεψης (intra prediction mode) στοιχείου χρώματος σύμφωνα με τις πρώτες πληροφορίες, όταν ο τρόπος λειτουργίας ενδο-πρόβλεψης του στοιχείου χρώματος δεν μπορεί να προσδιορισθεί σύμφωνα με τις πρώτες πληροφορίες την εξαγωγή των δεύτερων πληροφοριών στη δυφιορρευματική τεχνική, και τον προσδιορισμό του τρόπου λειτουργίας ενδο-πρόβλεψης του στοιχείου χρώματος σύμφωνα με τις δεύτερες πληροφορίες, όπου οι πρώτες πληροφορίες περιλαμβάνουν τις πληροφορίες για την ένδειξη του κατά πόσον ο τρόπος λειτουργίας ενδο-πρόβλεψης του στοιχείου χρώματος είναι ένας τρόπος λειτουργίας DM ή ένας τρόπος λειτουργίας LM, οι δεύτερες πληροφορίες χρησιμοποιούνται για να υποδείξουν έναν εναπομείναντα τρόπο λειτουργίας ως έναν τρόπο λειτουργίας ενδο-πρόβλεψης του στοιχείου χρώματος, και ο εναπομείνας τρόπος λειτουργίας είναι ένας από τους διαθέσιμους τρόπους λειτουργίας ενδο-πρόβλεψης του στοιχείου χρώματος διαφορετικός από έναν τρόπο λειτουργίας ο οποίος μπορεί να προσδιορισθεί σύμφωνα με τις πρώτες πληροφορίες. Η συσκευή συμπεριλαμβάνει μία πρώτη μονάδα εξαγωγής, μία πρώτη μονάδα προσδιορισμού, μία δεύτερη μονάδα εξαγωγής, και μία δεύτερη μονάδα προσδιορισμού. Οι προαναφερόμενες τεχνικές λύσεις μπορούν να μειώνουν τις πληροφορίες κωδικοποίησης ενός τρόπου λειτουργίας χρώματος και να βελτιστοποιούν τη διαλογή των πληροφοριών για να μειώσουν τα βήματα κωδικοποίησης ή αποκωδικοποίησης, μειώνοντας κατά αυτόν τον τρόπο την πολυπλοκότητα της κωδικοποίησης ή της αποκωδικοποίησης και βελτιώνοντας την απόδοση της αποκωδικοποίησης.
