摘要
设计了一款基于三网融合的数字家庭媒体中心。采用SMP8644做高清解码与系统控制,配备UTI机卡分离的有线数字电视(DVB-C)接收模块、e家佳家庭子网控制模块、CBHD蓝光光头机芯和前端处理模块以及一些外围接口,通过SATA接口可内置或外挂大容量硬盘,通过10/100 Mbit/s以太网卡和WiFi无线网卡,可以上网连接固定网站,并实现与数字家庭子网中的计算机、移动媒体终端及其他设备互连,实现资源共享。通过外接CVBS摄像头和传声器,可扩展支持视频通话。通过UART接口外接TD-SCDMA模块,可进行3G数据通信。对构成的硬件、软件系统做了简要介绍。
A digital home media center is designed based on the tri-networks integration. SMP8644 is adopted for HD video and audio demodulation and system control, and some modules are provided, such as a module for receiving cable TV （DVB--C） according to the specification of UTI conditional access separation, a module for controlling home sub-network complied with the specification of I Top Home （industry alliance of home network standard）, a module for pick-up and mechanism of CBHD blue- ray disc player, a module for front end signal process, some interfaces for peripherals. A high capacity HDD can be built in or connected outside to it by SATA interface. Via 10/100 Mbit/s Ethernet network card or wireless network card, it can be connected to some specific websites and can be joined to computers, mobile media terminals and other equipments in digital home sub-network to share resources with each other. It can be extended to support video call via connecting CVBS camera and microphone outside. It also can fix up a TD-SCDMA module outside by UART interface for 3G digital communication. The hardware and software of this system are briefly introduced in this paper.
