Set-top box EPG application transplanting development interface system

Abstract

The invention relates to digital STB EPG application transplanting development interface system, especially a relatively convenient interface design for different STB platforms to make universal transplating development. And the invention comprises chip OS (operating system), OSD, Demux Stor, Channel, and Others standard interfaces, hardware driving modules and chip OS, where the standard interface is a set of standard functions of describing the corresponding hardware driving modules and chip OS, designed according to the current basic EPG application's functional requirements and by considering feasibility of bottom-layer hardware driving modules and OS interface; and it adopts a common transplating mode, uniformly packing the bottom-layer hardware driving modules and chip OS fuction according to the defined standard interfaces at lower cost, forming the interface system.

Description

technical field [0001] The invention relates to an interface design scheme for application transplantation and development of a digital TV set-top box, in particular to a more convenient interface design for digital TV terminals for general transplantation and development for different set-top box platforms, that is, a set-top box EPG application transplantation development interface system. Background technique [0002] Based on the promotion of digital TV, the corresponding digital TV set-top box (Set Table Box, STB) has become an indispensable tool. Electronic Program Guide (EPG, Electronic Program Guide) is an application program running on the digital TV set-top box made to facilitate digital TV users to obtain and browse digital TV program channel information. It provides users with text, The human-computer interaction interface composed of graphics and images displays TV program information and navigation of various services to users. Through the electronic program g...

Problems solved by technology

[0007] Compared with the two methods 1 and 2, the former is combined with the bottom layer and the application, and each manufacturer designs the application independently, and it is almost impossible to transplant EPG applications to each other, basically it has to be developed from scratch; although the latter avoids this situation, it is relatively For the current domestic set-top box consumption level, the expensive middleware integration cost is not worth the candle. At the same time, the middleware takes up a lot of memory space due to the integration of various interface technologies, which is reduced for the limited memory space of the set-top box. Therefore, there are almost no domestic set-top boxes that actually integrate middleware and are put into the market.
