摘要
为了能够实现传统的家电影音设备与网络媒体服务的互连互通,满足人们对数字媒体资源家庭网络共享的要求,提出了一种基于DLNA标准的数字媒体适配器的系统设计方案,并完成了系统的软硬件架构设计、以及基于UP-NP协议栈中间层的软件设计。该系统的硬件部分采用Amlogic公司的AML 8726-M芯片,构成可组合的模块化硬件平台,软件部分完成对内核的裁剪以及硬件驱动,中间层基于UPNP协议栈及UPNP AV架构,以嵌入式linux为操作系统进行编程,能够实现DLNA设备间的零配置连接,实现媒体资源的输出播放。
In order to achieve the interconnection between the traditional home appliance audio equipment and network media services,to meet the requirements that people can share the media resources in home network,this paper puts forwards a System design of the digital media adapter based on DLNA,and accomplish the design of the hardware and software architecture,and the middle layer the UPNP protocol stack.The hardware part of the system adopts the Amlogic AML 8726-M processor,constitute a combination of modular hardware platform.The software accomplish the clipping of the kennel and the driving of the hardware.The interlayer based on the UPNP protocol stack and UPNP AV framework,with embedded operating system Linux for for programming.It can realize the connection and the output of the broadcast media resources without any configuration between the DLNA equipment.
