| Abstract |
This paper propose a real-time forensic mark technology based on HEVC(High Efficiency Video Coding) standard using heterogeneous systems of CPU and GPU. The previous HEVC-based copyright protection technology is delayed in ultra-high resolution video because it inserts marks through decoding and re-encoding process to prevent image quality deterioration. The proposed technique excepts the decoding and re-encode process of the highly complex HEVC process and inserts the mark using only entropy coding. And It is a technology that enables real-time copyright protection by processing high-speed bit operation (XOR) processing of the zero value of QTC(Quantified Transform Coordinators) area and the forensicmark using multi-cores of CPU and GPU. As a result of comparing this method with the previous study at ultra-high resolution (8K 60FPS), the Peak Signal-to-Noise Ratio (PSNR) increased by 10dB. As a result of comparison, it showed 2-4% higher performance. In addition, the forensic mark insertion speed is increased by more than 70 times compared to existing research, enabling real-time copyright protection. |
