METHOD FOR DECODING A POWER SCALABLE DIGITAL VIDEO

摘要

PURPOSE: A method for decoding a power scalable digital video is provided to extend the battery life of a portable electronic device by decoding image data by a power scalable scheme. CONSTITUTION: A target platform is defined(180). A plurality of video decoding profiles are discriminated(182). Each performance of a plurality of the video decoding profiles is measured by a plurality of video streams(184). A part of a plurality of the video decoding profiles is discriminated(186). Each of a part of a plurality of the video decoding profiles is associated with a different power level.
