We present a straightforward, non-intrusive adaptive bit rate streaming segment quality selection policy which aims at extending battery lifetime during playback while limiting the impact on the user's quality of experience, thus benefiting consumers of video streaming services. This policy relies on the relationship between the available channel bandwidth and the bit rate of the representations in the quality ladder. It results from the characterization of the energy consumed by smartphones when running adaptive streaming client applications for different network connections (Wifi, 4G, and 5G) and the modeling of the energy consumed as a function of said relationship. Results show that a significant amount of energy can be saved (10 to 30%) by slightly modifying the default policy at the expense of a controlled reduction of video quality.

无线自适应流媒体客户端的能源和质量感知视频请求策略


我们提出了一种简单的、非侵入性的自适应比特率流媒体分段质量选择策略，旨在延长播放过程中的电池寿命，同时限制对用户体验质量的影响，从而使视频流服务的消费者受益。该策略依赖于可用信道带宽与质量阶梯中表示的比特率之间的关系。它源自智能手机针对不同网络连接（Wifi、4G 和 5G）运行自适应流媒体客户端应用程序时所消耗的能源特征，以及作为所述关系的函数所消耗的能源的建模。结果表明，通过稍微修改默认策略，可以节省大量能源（10% 到 30%），但代价是视频质量的受控降低。
