Title: CONTENT-AWARE ENERGY SAVINGS FOR VIDEO STREAMING AND PLAYBACK ON MOBILE DEVICES
Abstract:
A system, computer readable medium, and method are provided for reducing the power consumption of a mobile device. The method includes the steps of detecting video content to be viewed in an application executed by the mobile device; detecting unwanted content associated with the video content; and operating the mobile device in a low-power mode during playback of the video content in the application in response to detecting the unwanted content. The mobile device may include a memory storing the application and a processor executing the application, which configures the processor to implement the method. Five techniques may be applied in the low-power mode to reduce power consumption including Dynamic Voltage and Frequency Scaling (DVFS), reducing resolution of content, reducing brightness of a display, masking content, and thread throttling. The low-power mode saves energy when playing back videos on the mobile device.
