Method for calculating the addresses in the navigation pack of a VOBU unit |
摘要 |
<p>A picture target amount-of-code calculating unit (14) calculates a target amount of codes for each picture type that corresponds to an encoding rate that has been determined by an audio/video encoding rate determining unit (13). An amount-of-code controlling unit (12) controls the quantizing scale of a quantizing unit so as to make the target amount of codes for each picture type match with a total amount of codes of a unit as a whole. A unit address calculating unit (15) calculates the addresses used when a search is made, as navigation data, on the basis of the target amount of codes for each picture type and the encoding rate. A unifying unit (17) makes a construction of the unit while, on the other hand, a navigation data producing unit (16) depicts navigation data at a foremost position of the unit.</p> |
