Complexity scalable IDCT based approaches for power-efficient video decoding

Running a multimedia application such as audio playback or video playback on a mobile handheld device is a power hungry task. Mobile devices in question here may include smart phones, palmtops or ipods. As the battery time is limited on these platforms, complexity cutting and power saving is a critical issue and optimization of such power intensive tasks is inevitable. This paper outlines two complexity scalable approaches for video decoding on embedded platforms.
