该论文提出了一款支持4096×2160p分辨率的212MPixels/s多视点视频编码器芯片,用于3D/四倍高清电视应用。通过视差估计有效利用视间冗余,降低比特率20%-30%。
Chiu, Yu-Han Chen, Pai-Heng Hsiao, Shao-Yi Chien, Tung-Chien Chen, Ping-Chih Lin, Chia-Yu Chang, Liang-Gee Chen National Taiwan University, Taipei, Taiwan To provide more vivid perception, TV resolution is increasing dramatically. In addition, 3D video is emerging because it can present immersive and complete scenes. Therefore, multiview video coding (MVC) is currently being developed as an extension of H.264/AVC [1]. Disparity estimation (DE), which effectively exploits the inter-view redundancy and reduces bit rates 20% to 30%, is the most significant feature. However, DE and motion estimation (ME) require ultra-high computation and memory access. To encode a 3-view 1080p video, 82.4TOPS computing power and 54.6TB/s memory access are required with a full search algorithm. Moreover, view scalability is a critical functionality to deal with various MVC structures. There are 3 challenges to design an efficient MVC encoder chip: 1) Encoding
