Power-aware H.264 computation resource allocation

The high computational complexity of H.264 poses as a challenge for it´s feasibility in power-constrained devices. In this paper, the key modules of the encoder which can be power-optimized are analyzed at first. Based on the analysis results, a novel computation resource allocation method is proposed. The algorithm can allocate the computation resource of the encoder adaptive to available battery power and video contents. Experimental results show the proposed algorithm can highly reduce the computation resource while maintaining video encoding quality.
