Power consumption of video decoding on mobile devices

This paper investigates the impact of various codecs and coding parameters on power consumption of video decoding on mobile handheld devices. With limited battery capabilities of mobile device and with current trend of an increased demand on quality of video contents the power management becomes the vital aspect for mobile devices. Besides the decoding complexity, the file size of the investigated codecs is also taken into account. By using SSIM (Structural SIMilarity index) metric, the measured results for power consumption and storage demand are correlated with perceived video quality.
