摘要
视频传输时受到带宽波动的影响,会导致最终接收到的视频质量不稳定,因此,本文提出一种分级的视频传输控制方案,该方案由尽力而为、帧率优先和质量优先三种视频传输方案组成,实验表明,分级的视频传输控制方案在网络带宽波动时,可根据用户的不同需求,提供相应的视频质量保证。
The quality of video at receiver will be unstable when video transmission is influenced by network bandwidth fluctuation. Therefore, a hierarchical video transmission mechanism is proposed which are composed of three video trans-mission scheme-best effort, frame rate preferred and quality preferred. Experimental data shows our mechanism can provide corresponding QoS of video to meet user’s various requirements when network bandwidth fluctuates.
