Abstract

Η παρούσα εφεύρεση αφορά μια μέθοδο επανασυγχρονισμού η οποία επιδιώκει τον επανασυγχρονισμό ενός συμπιεσμένου σήματος δεδομένων βίντεο που λαμβάνεται από έναν αποκωδικοποιητή, μετά τον εντοπισμό σφάλματος μετάδοσης στο εν λόγω συμπιεσμένο σήμα δεδομένων βίντεο. Η μέθοδος επανασυγχρονισμού βασίζεται στη χρήση λέξης επανασυγχρονισμού. Προκειμένου να διασφαλιστεί η σωστή αποκωδικοποίηση του συμπιεσμένου σήματος δεδομένων βίντεο, η λέξη επανασυγχρονισμού είναι διακριτή από τις γνωστές λέξεις VLC, καθώς και τον κώδικα έναρξης VOP.
