摘要
Mirror Link是汽车行业里推出的唯一统一标准,旨在规范手机与车机互联,给用户带来方便实用的体验效果,但是Mirror Link的VNC在传输多媒体数据的时候帧率低,卡顿现象严重,且不支持语音控制,这严重影响了用户的体验效果。针对这个不足,课题组修改了VNC传输协议方法,设计出了一种新的多媒体传输方案。实验结果表明,VNC实时性有所增强,在多媒体传输中视频能够流畅播放,同时有效地降低了CPU利用率。
Mirror Link is the automotive industry＇s only uniform standard, it is designed to regulate the mobile phone and the vehicle connecting, and give users a convenient and practical experience. But the frame rate is low in the VNC of Mirror Link in the transmission of multimedia data, and it cannot supports voice control, which will seriously impact the user＇s experience.To modify thisdeficiency, our research group changed the VNC transport protocol method into a new multimedia transmission program, we also input a voice control system in the VNC transport protocol. The results show that the function of VNC has been strengthen. Videos can be played smoothly in the multimedia transmission,in addition,the CPU utilization was reduced, and the voice control function was implemented successfully.
