摘　　要：数字电视机顶盒(STB)实现接收数字电视和接入Internet网络两种基本应用功能,传统的解决方案必须由两种主要芯片来完成。CX24430是机顶盒设备的核心芯片,它集成了一个Cable Modem和一个互动电视MPEG解码器,由单芯片来代替两种芯片,因此可以减少系统的软硬件开销,降低系统的成本开支。介绍CX24430的主要特点、内部结构及其典型应用。Digital TV set-top-box （STB） realizes receiving digital TV and connecting internet network two basic application functions. Traditional solving plan is completed with two chips. CX24430 integrates a Cable Modem and interactive TV MPEG decoder. CX24430 STB solving plan substitutes two chips for single chips thus to reduce the hardware and software cost of terminal system. CX24430 is the main chip in set-top-box. The feature, internal structure, pin functions and typical application of CX24430 are given.
