基于通知服务的车载多媒体网络视频传输研究

摘要

为了增强车载信息娱乐系统功能，满足日益增加的车载多媒体网络对于视频传输的功能性需求，深入研究了 MOST （Media Oriented System Transport）网络（一种车载多媒体网络）视频传输的原理，并探讨了在 MOST 网络视频传输中引入通知服务的可行性。根据 MOST 网络视频传输的原理和通知服务的特点进行实验，并有效地实现两者的结合。实验结果表明，通知服务可以使MOST 网络视频数据传输具有更强的应用空间，并且节省 MOST 网络控制信道带宽。%To enhance the function of in-vehicle infotainment system and to meet growing functional needs of in-vehicle multimedia network for video transmission,we make the thorough study on the principle of MOST (media-oriented system transport)network (which is an in-vehicle multimedia network)video transmission,and discuss the possibility that to introduce notification service to MOST network video transmission.We carry out the experiment based on the principle of MOST network video transmission and the feature of notification service, and effectively realise the combination of them two.Experimental result proves that the notification service can make MOST network video transmission apply widely,and it can save bandwidth for MOST network control channel.
