基于Android的机顶盒CAS系统的开发

Development of Set-top Box CAS System Based on Android

详细阐述了机顶盒CAS终端子系统的设计过程,提出一种CAS子系统软件框架,并介绍了Android系统的NDK环境搭建以及上层应用(JAVA)与底层(C语言)的无缝衔接,并成功地把CAS子系统移植到Android系统中。实验证明,此CAS子系统可以稳定地在华为H3716C平台(Android平台)上运行。

This article elaborates the design process of set-top box CAS terminal subsystem in detail, puts forward a software framework of CAS subsystem and introduces NDK environment building of Android system and the seamless convergence between the application layer（JAVA） and the underlying layer（C language）. CAS subsystem is successfully transplanted to Android system. Experimental results prove the CAS subsystem can stably run on Huawei H3716C platform（Android platform）.
