Method and apparatus for efficiently allocating memory in audio still video (ASV) applications

A method of dynamically allocating available audio still video (ASV) buffer memory space in an ASV buffer for a current pack in a DVD audio bitstream, comprising:

• (a) determining a pack type of the current pack;
• (b) updating an ASV table with a pointer corresponding to an available memory location in the ASV buffer memory space;
• (c) concurrently with the updating, storing a current payload associated with the current pack to the available memory location;
• (d) incrementing a pack counter;
• (e) computing a next ASV memory write address based upon the incremented pack counter;
• (f) determining a next pack type based upon the current pack type;
• and
• (g) repeating (a)-(f) for a next pack in the bitstream when the current pack is not a last pack in the bitstream.
