Abstract

In this paper, a region of interest (ROI) oriented partial H.264/AVC decoding scheme is proposed to enable low-power and low-complexity HD video content display on low resolution screens. The proposed scheme is a macroblock level based partial decoding, which employs several strategies to maintain the good video quality in the ROI The simulation results show that, the proposed scheme provides better visual quality, and very limited PSNR loss quality in the ROI, but it achieves much lower computational complexity and power consumption. On average, it reduces the decoding time by about 40.66% with the PSNR loss up to O.77dB in the ROI among the test cases. The partially decoded sequences maintain more details in the ROI, thus provide better user experience. This proposal is especially useful for the portable devices.
