About the Digital TV receiving system software platform
Middleware is a software platform for digital TV reception systems that provides a working environment and software interface for digital television applications.
Middleware, as a separate software layer in the digital set-top box, separates the application software from the underlying hardware and operating system, defines a unified interface to the operating system and drivers, and also defines a uniform interface to applications. In addition, Radio and television services and value-added services also provide a unified interface.
Middleware defines a set of more complete and standard application programming interfaces that make applications independent of the operating system and hardware platform, making application development easier and making the product more open and portable.
It is usually composed of Java virtual machines, web browsers, image and multimedia modules, and the middleware separates the application software from the hardware-dependent driver layer software so that the application software does not depend on the specific hardware platform.
