SMART SET-TOP BOX AND OPERATING METHOD FOR SMART SERVICE AND DIGITAL TELEVISION SERVICE USING SINGLE OPERATING SYSTEM

摘要

A smart set-top box (STB) that provides a smart service and a digital television (DTV) service using a single operating system may be provided. The STB may load applications designed based on an application programming interface (API) of a framework corresponding to the operating system, may load a DTV stack including a DTV service function and a security service function, and may allow communication between at least one of the applications and the DTV stack when the at least one of the applications uses a binder driver included in a kernel of the operating system so as to access the DTV service function included in the DTV stack.
