Abstract:
The method was introduced to encapsulate the detailed controls of the concrete DVB-CI device with device driver and provide the uplayer program an abstract device on the embedded Linux system. A DVB-CI device driver based on MontaVista's Hard Hat Linux system and IBM STB02500 Set-Top Box Integrated Controller was implemented as an example.
Key words: embedded Linux, digital TV, PCMCIA, DVB-CI, CA(Conditional Access)
摘要：
介绍了在嵌入式Linux系统中，使用设备驱动程序隐藏具体DVBCI设备的控制细节、向上层程序提供抽象DVBCI设备的方法，并以MontaVista的Hard Hat Linux系统、IBM的STB02500机顶盒硬件平台为例，说明了DVBCI设备驱动程序的实现方法。
