It typically has multiple inputs and one output. A <CODE>Multiplexer</CODE> can also have a single track as input. In this case, multiple tracks don't have to be interleaved, but the <CODE>Multiplexer</CODE> might format the output stream with additional data interleaved with the input track. <p> If a <code>Multiplexer</code> implements the <code>Clock</code> interface, it can be used by a <code>Player</code> as the master time base for synchronization. In this case, the <code>Multiplexer</code> should update the media time and time-base time as it processes the media.<P><DL><DT><B>Since: </B><DD>JMF 2.0</DD></DL><HR><P><!-- ======== INNER CLASS
