车载系统MirrorLink方案的研究

Research of head-unit MirrorLink solution

介绍了车载系统的MirrorLink方案,分析了它的协议架构,对其两个主要内容——VNC架构和音视频传输架构做了介绍。分析了VNC架构中的核心RFB协议的过程和实现,RFB协议是负责MirrorLink系统中的界面传输和控制信号的传递,对它的编码要求进行分析,提出了更加优化的编码方式;在音视频架构中,提出了一种改进的可应用于车载MirrorLink中的UPnp视音频传输方案。

This paper presents the car＇ s MirrorLink solution, analyses the protocol architecture. It simply introduced the two main content-VNC architecture and audio ＆ video transmission ＇architecture. In VNC architecture introduced the core protocol-RFB protocol implementation,it used to transfer the HMI screen and the control signals, analyzed coding requirements and proposed more optimized coding methods. In audio ＆ video transmission architecture it proposed an improved UPnp video and audio transmission scheme ,it can be applied to the vehicle MirrorLink solution.
