Abstract
Sposób kodowania obszaru odsłoniętego w strumieniu danych sekwencji wielowidokowych przez koder entropijny, obejmujący następujące kroki: (a) koduje się blok widoku bazowego; (b) przechowuje się stan oraz wartości prawdopodobieństw kontekstów kodera entropijnego w module przechowywania kontekstu z odniesieniem identyfikującym blok widoku bazowego; (c) powtarza się wspomniane kroki kodowania oraz przechowywania dla każdego bloku widoku bazowego strumienia danych sekwencji wielowidokowej; (d) rozpoczyna się kodowanie obszaru odsłoniętego oraz dzieli się na bloki odsłonięty obszar widoku bocznego powiązanego z widokiem bazowym; (e) określa się, dla bloków sąsiednich względem aktualnie kodowanego bloku, które nie znajdowały się w obszarze odsłoniętym, blok odniesienia w widoku bazowym, wykorzystując bazę danych odniesień dla bloków; (f) gdy odnajdzie się takie odniesienie, odczytuje się uprzednio zapisany stan oraz wartości prawdopodobieństw kontekstów kodera entropijnego dla bloków odniesienia; (g) kopiuje się wszystkie tryby kodowania z bloku odniesienia do sąsiada; (h) podaje się stan i wartości prawdopodobieństw kontekstów do kodera entropijnego do bloku poprzedzającego obecnie kodowany blok; (i) koduje się, za pomocą kodera entropijnego, wybrany blok widoku bocznego; (j) powtarza się kroki od (e) do (i) dla wszystkich bloków widoku bocznego powiązanych z widokiem bazowym, przetwarzanych w krokach od (a) do (b).
