摘要： A method and apparatus for providing audio in a digital video system. Equations for a value n are provided for replacement into the conventional audio data shuffling equations. The equations for the value n provide for simple, efficient techniques to, in turn, calculate values for track number (TK), block number (BK), and data position number (DP). The values TK, BK, DP can be used in an address generation scheme to generate a page value and an offset value. The page value and the offset value for a particular sample of digital audio data, in part, determine the location of the sample in a memory storing the digital audio data. The present invention can be implemented for both four channel and two channel modes under both the NTSC and the PAL standards in accordance with specifications set forth in the Digital Video Standard (the “Blue Book”).
