Xlet

An Xlet is very similar to a Java applet and is designed to support applications for Digital TV. Xlets, unlike applets, can be paused and resumed. The Xlet interface is part of Sun's JavaTV specification.

The interface for an Xlet is defined in the java.tv.xlet package:

public interface Xlet { public void initXlet(XletContext ctx) throws XletStateChangeException;

public void startXlet() throws XletStateChangeException;

public void pauseXlet();

public void destroyXlet(boolean unconditional) throws XletStateChangeException;}

The pause/resume feature is essential for a Set-top box (STB) environment, which has limited memory resources and restrictions on bandwidth from the headend provider.
