After discussing video compression, quality, and performance aspects in the previous chapters, in this chapter we turn our attention to another dimension of video application tuning: power consumption. Power consumption needs to be considered together with those other dimensions; tradeoffs are often made in favor of tuning one of these dimensions, based on the needs of the application and with a view toward providing the best user experience. Therefore, we first introduce the concept of power consumption and view its limits on typical modern devices, then we follow with a discussion of common media workloads and usages on consumer platforms. After that, we briefly introduce various criteria for power-aware platform designs.
