rrently multiplexed bitstreams may be chained
consecutively. Such a physical bitstream obeys all the rules of both
grouped and chained multiplexed streams; the groups, when unchained ,
must stand on their own as a valid concurrently multiplexed
bitstream.</p>

<h3>multiplexing example</h3>

<p>Below, we present an example of a grouped and chained bitstream:</p>

<p>In this example, we see pages from five total logical bitstreams
multiplexed into a physical bitstr
