ogical bitstreams multiplexed at the page level and may
include a 'meta-header' at the beginning of the multiplexed logical
stream that serves as identification magic. Whole pages are taken in
order from multiple logical bitstreams and combined into a single
physical stream of pages. The decoder reconstructs the original
logical bitstreams from the physical bitstream by taking the pages in
order from the physical bitstream and redirecting them into the
appropriate logical decoding entity. The simplest physi
