Abstract
Editors' note:Backlight power minimization can effectively extend battery life for mobile handheld devices. This article proposes an adaptive middleware-based approach to optimize backlight power consumption when playing streaming video. The technique simultaneously minimizes the negative impact on perceived video quality. -Radu Marculescu, Carnegie Mellon University; and Petru Eles, Linköping University
