Have a look to
http://www.javaworld.com/javaworld/jw-04-1997/jw-04-jmf.html?page=1[^]
on the third page they say...

The java.media.Player interface extends from the Controller interface, which itself extends the Clock interface. The Clock interface specifies methods used for synchronization and timekeeping, while Controller adds variables and methods used to track state and state transitions

and on the 4th page...

Other advanced features are provided for in the Player API. Any player may act as a controller for one or more other players. This synchronization is achieved through the use of TimeBase objects, which function as clocks in JMF. Players can synchronize with one another using methods such as getTimeBase and setTimeBase.

因此，寻找Java.Media.Player clock会得到一些可能对您有帮助的结果.
