Package org.dvb.spi Description

This package defines a central registry for all DVB Service Provider Interface (SPI) providers. This encourages a consistent architecture for such providers. Additionally, it gives some support for debugging. For example, a list of installed providers might be useful in a crash log.

In normal operation, xlets using a provider never get a direct reference to that provider. Rather, xlets interact with the terminal through standardized APIs, such as Java TV. The service underlying those underlying APIs can be:

• An integrated part of the implementation, or
• interoperable downloaded code, either in the form of an xlet-bound or a system-bound provider.

NOTE: The Java platform class java.security.Provider is unrelated to the providers defined in this package and its subpackages. Additionally, java.security.Provider in the Java platform is typically associated with a completely different lifecycle model.
