Abstract :
Video encoding is one of the most appealing features of modern mobile terminals, but also one of the most demanding for what concerns power consumption. We propose an H.264/AVC encoder able to adaptively self-adjust the accuracy of the motion-compensated prediction on the basis of the available power resources to achieve a progressive reduction of the computational requirements with graceful degradation of the rate-distortion performance.
