    • A method, an apparatus, and a system for adjusting a multimedia encoding rate are disclosed. The method includes: obtaining an expected multimedia encoding rate by using the available network bandwidth corresponding to the transmission path of a multimedia service, the expected QoE of the multimedia service, and the current multimedia encoding rate as input parameters and according to a preset multimedia resource policy decision, where the expected multimedia encoding rate is used as a reference for adjusting the current multimedia encoding rate. With the present disclosure, under the current network performance, an optimal point for balancing the effects of the media encoding rate and the network performance on the QoE is found by adjusting the multimedia encoding rate, thus achieving optimal QoE. In this way, the adjustment process is simple and fast and the success rate is high, thus improving the QoE.
    • 公开了一种用于调整多媒体编码速率的方法,装置和系统。 该方法包括:通过使用与多媒体业务的传输路径相对应的可用网络带宽,多媒体业务的预期QoE和当前多媒体编码速率作为输入参数,并根据预先设定的多媒体资源来获得期望的多媒体编码率 策略决定,其中期望的多媒体编码率被用作调整当前多媒体编码率的参考。 通过本公开,在目前的网络性能下,通过调整多媒体编码速率,找出平衡媒体编码速率与网络性能对QoE的影响的最佳点,从而实现最佳QoE。 这样,调整过程简单快速,成功率高,提高了QoE。
