| 摘 要： | 无线实时视频传输已成为当前通信领域发展的热点,但当前的无线通信技术提供的带宽尚无法满足高码率的实时视频传输的需求.针对这一问题,设计并开发一个基于多链路聚合技术的无线实时视频传输系统.该系统通过聚合多链路带宽,对各链路运用TFRC速率控制,有效地提高数据传输速率和稳定性,同时采用提早丢弃和关键帧优先发送等实时性优化策略,获得更好的视频传输质量.

| Abstract: | Currently wireless real-time video transmission has become very hot,however,the bandwidth of those existing wireless transmission channels is not enough to meet the needs of high bit-rate real-time video transmission.To solve this problem,this paper designed and implemented a wireless real-time video transmission system based on multi-link aggregation.Our system aggregated the bandwidth of multiple links,used TFRC rate control on each link and adopted some optimizations such as early-drop and key-frame firs... |
