Power Consumption and Bandwidth Savings with Video Transcoding to Mobile Device-specific Spatial Resolution
Usage of mobile devices for multimedia content playback is drowning the battery power rapidly. High quality videos which are streamed from the internet are power consuming and demand high network bandwidth. We measured the power consumption and bitrate of video sequences in respect to different spatial resolutions and used acceptability-based Quality of Experience (QoE) model for determining the impact of video resolution on QoE. The results showed that both power and bandwidth can be saved without noticeable reduction in QoE when transcoding video to a resolution specific to the mobile device instead of using standard video resolutions.
