Middleware Introduction
 
Middleware is a kind of independent system software or service program. By integrating middleware, distributed applications can share resources. Middleware is located on the client/server operating system, it manages computer resources and network communication. It is the software that connects two separate applications or stand-alone systems. When systems are connected, even though they have different interfaces, they can exchange information through middleware. Information transmission is a key way of implementing middleware. Through middleware, applications can work on multi platform or OS.
 
When it comes to set-top box, middleware is located between set-top box internal real-time operating system and application software, it exists in the form of application program interface (API), the API set are stored in the digital STB flash memory.
 
 
Functions of Middleware
 
Middleware is to digital set-top box as Windows operating system is to PC. It can standardize digital TV interactive function, and reduce the data quantity of the service project (the application and set top box) to the minimum. Middleware system includes a series of functions, such as memory management, communication management, graphics system management, SI data loading, system resource management and communication and control between the front-end systems etc.
 
 
Digital Set-top Box Middleware System
                                            
Digital set-top box middleware system is hierarchical structure composed of many modules including the set-top box driver layer, core system module, multimedia module and the lower platform interface, SI engine, etc.
 
STB Driver layer design and compile by the set-top box manufacturers according to the Standard Specification, which provides MPEG 2 table data extraction, conditional access and smart card control, channel parameter setting, audio/video streaming control, Moderm management, TVPVCR control and other functions. The core system module system consists of a series of modules, including memory management, thread control, event management, safety control, data download management and network management protocol (TCPPZP, PPP, HTTP) etc. Image, multimedia module and the lower platform interface, provide advanced functions for graphics, multi window management and audio/video control. SI engine manage the Si database. It is responsible for the extraction of EIT, PMT and other common Si table data, and it has supervisory function, it also can search stored data, such as the channel name.
