API = Application Programming Interface
The Java TV application programming interface (API) is an extension of the Java platform developed through an open process by Sun Microsystems and leaders in the digital television industry. Major consumer electronics manufacturers have announced their public support for the adoption of this API as a digital television standard worldwide.
The Java TV API is being designed to provide access to functionality unique to digital television receivers, including:
Audio/video streaming
Conditional access
Access to in-band and out-of-band data channels
Access to service information
Tuner control for channel changing
On-screen graphics control
In addition, the Java TV API is being designed to provide additional functionality in the form of media synchronization and control of the application life-cycle. Media synchronization will allow interactive television content to be synchronized with the underlying video and background audio of a television program. Application life-cycle control will enable content to coexist gracefully with television programming content such as commercials.
Overall, the Java TV API and the underlying Java platform will enable content developers to create truly compelling, differentiated interactive television content for the viewer.
