摘　　要：通过海事卫星传输流媒体视频已成为当前通信领域发展的热点,但海事卫星由于其本身通信资源的不足,其提供的带宽尚很难满足高码率的实时视频传输需求。针对这一问题,提出了一种链路聚合解决方案,通过链路聚合多路卫星链路,采用对流媒体视频数据进行分拆、传输路由分配和控制、以及数据缓冲、帧失序控制等方法,实现数据传输速率的提高,从而有效提升海事卫星链路流媒体视频的传输质量。Transmitting streaming media via Inmarsat system has become a hot spot in communication.However,the bandwidth of Inmarsat system is quite limited for high bit rate real time videos. To solve this problem,a method called link aggregation technology is proposed. Channels of the satellite are bundled together in software application layer,and the streaming media packets are transited through the bundled channels with techniques of packets splitting,multi-path routing and controlling,buffering,as well as transmitting order management. Experimental results show that this method could support high bit rate and enhance the transmission quality of the streaming media.
