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.
Wireless real-time video transmission has become a hot spot in the field of communication at present, but the bandwidth provided by the current wireless communication technology can not meet the demand of real-time video transmission with a high code rate.To solve this problem, a multi-link aggregation technology Of wireless real-time video transmission system.This system by aggregating multi-link bandwidth, the use of TFRC rate control for each link to effectively improve the data transfer rate and stability, while using early discard and key frame priority real-time optimization strategy, Get better video quality.
