Abstract

Περιγράφεται ένα ψηφιακό σύστημα τηλεοπτικής λήψης, το οποίο έχει ένα μηχανισμό ασφαλείας, ο οποίος χειρίζεται ταυτόχρονα δύο ή περισσότερα τηλεοπτικά σήματα. Το σύστημα περιλαμβάνει μια πληθώρα ψηφιακών μηχανισμών τηλεοπτικής λήψης προκειμένου να λαμβάνει πολλές ξεχωριστές ροές σημάτων τηλεοπτικών προγραμμάτων. Επίσης, το σύστημα περιλαμβάνει ένα μηχανισμό πολυπλεξίας συνδεδεμένο με τους ψηφιακούς μηχανισμούς τηλεοπτικής λήψης προκειμένου να ενώνει και να πολυπλέκει τις εισερχόμενες ροές τηλεοπτικών σημάτων σε μια ενιαία συνδυασμένη ροή σήματος. Η συνδυασμένη ροή σήματος παρέχεται σε ένα μηχανισμό ασφαλείας, ο οποίος περιορίζει την χρησιμοποιήσιμη πρόσβαση στη συνδυασμένη ροή σήματος στους εξουσιοδοτημένους χρήστες. Το σύστημα λήψης περιλαμβάνει επιπλέον ένα μηχανισμό αποπολυπλέκτη για να λαμβάνει από τον μηχανισμό ασφαλείας μια συνδυασμένη ροή σήματος με εξουσιοδότηση πρόσβασης και να αποπολυπλέκει την συνδυασμένη ροή σήματος στη συνέχεια σε ξεχωριστές ροές τηλεοπτικών σημάτων που αντιστοιχούν στις ξεχωριστές ροές τηλεοπτικών σημάτων που λαμβάνονται από τους μηχανισμούς λήψης. Το σύστημα περιλαμβάνει επίσης κύκλωμα, το οποίο ανταποκρίνεται σε μία τουλάχιστον από τις αποπολυπλεγμένες ροές τηλεοπτικών σημάτων για την παροχή σημάτων εικόνας σε ένα μηχανισμό τηλεοπτικής προβολής για τη δημιουργία τηλεοπτικών εικόνων.
