摘要: Video is the most prevalent traffic type on Internet today. Significant research has been done measuring user's Quality of Experience (QoE) through different metrics. We take position that energy use must be incorporated into quality metrics for digital video. present our novel, energy-aware QoE metric video, Energy-Video Index (EnVI). EnVI measurements from playback a diverse set online videos. observe 4K-UHD (2160p) video can ~30% more client device compared to HD (720p), and up ~600% network bandwidth than FHD (1080p), without significant improvement in objective measurements.
