| 摘要 |
采用定向流的终端自发现和注册机制 保证了服务端能够正确定位交互终端 对边缘 QAM 的带宽资源采用动态管理的方式 在终端开始会话时实时分配资源 会话结束时及时回收资源 基于该设计实现了一个以时移电视和视频点播业务为主体的用户交互媒体分发系统 实际运营结果表明该系统能够实现有限的传输带宽资源的最大利用率

| 摘要_英文 |
In designed system, a terminal registration and self-discovery schemes based on directional flow are designed to guar antee that real-time stream is correctly delivered from media server to the requesting terminal. The edge QAM resources is dy namically managed through allocation on request and reclaim on finishing. A time-shift TV and Video on Demand VoD interac tive media system is developed based on the design. The experimental results prove that the system can maximize the utilization of limited network bandwidth.
