Energy Analysis of Multimedia Video Decoding on Embedded Systems

Expanding components and applications on hand-held devices include radio, camera functions, audio, and video media, etc. Due to the complex computing characteristic of video decoding, the video application consumes large amount of energy and demands strict strategies for power management. Codecs are used to encode video media from original sources of films; lots of new compression codecs are released in recent years. In this paper, we aim to find the optimal video codecs on embedded systems from analyses of consumption of energy. Experiments have been done to investigate the effects of various codecs, file formats, and parameters of codecs.
