In static voltage mechanism MPEG video player, takes more energy. In the authors' paper Dynamic Voltage/frequency Scaling (DVS) mechanism is implemented and the player scales the voltage level for the frames of next interval based on decoding time prediction. The decoding time of a frame is predicted by the size and the type of the frame. They implemented their mechanism by modifying a traditional MPEG1 decoder. Their experiments show that a significant amount of processor energy savings can be achieved while enhancing QoS of video playback.
