Abstract

A találmány tárgya eljárás video képinformációk megjelenítési ésképrögzítési formátumának kiválasztására. A videokép-információkmegjelenítési formátumának kiválasztására szolgáló eljárás lényege,hogy (a) fogadják a különféle képfelbontási formátumok közül azegyikhez társított videokép-információt és feltételes hozzáférésiinformációt tartalmazó jelet; (b) dekódolják a vett jelben továbbítottfeltételes hozzáférési információt, ahol a dekódolt feltételeshozzáférési információ olyan adatokat tartalmaz, amelyek olyanképfelbontási formátumokra vonatkoznak, amelyek az alábbi két funkcióközül legalább az egyik végrehajtására alkalmas: (i) a videokép-információ rögzítése; és (ii) a rögzített videokép-információreprodukálása; (c) a dekódolt feltételes hozzáférési információalapján adaptív módon kiválasztanak egy képfelbontási formátumot; és(d) a kiválasztott képfelbontási formátum felhasználásávalfeldolgozzák a videokép-információt. A videokép-információmegjelenítési formátumának kiválasztására szolgáló eljárás egy másikváltozatának lényege, hogy (a) fogadják a különféle megjelenítésiformátumok közül az egyikhez tartozó videokép-információt ésmásolásvédelmi információt tartalmazó jelet; (b) dekódolják a beérkezőjelben fogadott másolásvédelmi információt, ahol a másolásvédelmiinformáció olyan adatokat tartalmaz, amelyek olyan megjelenítésiformátumokra vonatkoznak, amelyek alkalmasak az alábbi funkciók közülaz egyik végrehajtására: (i) a videokép-információ rögzítése; és (ii)a rögzített videokép-információ reprodukálása; (c) a dekódoltmásolásvédelmi információ alapján a videokép-információnak egyképernyőn történő megjelenítéséhez adaptív módon kiválasztunk egyformátumot; és (d) a kiválasztott megjelenítési formátumfelhasználásával feldolgozzák a videokép-információt. A videokép-információ képrögzítési formátumának kiválasztására szolgáló eljáráslényege, hogy (a) fogadják a különféle képrögzítési formátumok közülaz egyikhez tartozó videokép-információt és másolásvédelmi információttartalmazó jelet; (b) dekódolják a beérkező jelben fogadottmásolásvédelmi információt; (c) a dekódolt másolásvédelmi információalapján adaptív módon kiválasztanak egy formátumot a videokép-információnak egy képrögzítő közegen történő rögzítéséhez; és (d) akiválasztott képrögzítési formátum felhasználásával feldolgozzák avideokép-információt.
