8 k ultra-high definition (UHD) is paving the way for the next-generation video systems. In the audiovisual industry, besides delivering a more immersive experience, it is a mean to smooth spatial artifacts during video sampling. In the medical industry, it may provide surgeons with increased reality in surgeries such as endoscopy. Nevertheless, researchers are struggling to meet the high throughput required by this resolution and hardware solutions miss the flexibility required for on-demand updates. In this context, we propose an 8 k video-card based on a hybrid platform endowed with “soft” programmable logic and “hard” processors. The former accelerates the video pipeline from capture to encoding and playback—via SDI or PCIe. The later connects with a cloud to stream video and interfaces with the user. Results showed that our platform outputs 8 k UHD video in YUV 4:2:2 10-bits and H.264 formats at 60 and 30 frames per second, respectively.

墙屏：用于物联网的超高清视频卡

8 k超高清（UHD）正在为下一代视频系统铺平道路。在视听行业中，除了提供更身临其境的体验外，它还可以在视频采样过程中平滑空间伪像。在医疗行业中，它可以为外科医生提供诸如内窥镜检查之类的手术的更多真实性。尽管如此，研究人员仍在努力满足此分辨率所需的高吞吐量，并且硬件解决方案缺少按需更新所需的灵活性。在这种情况下，我们提出了一种基于混合平台的8 k视频卡，该混合平台具有“软”可编程逻辑和“硬”处理器。前者通过SDI或PCIe加快了从捕获到编码和回放的视频管道。后者与云连接以流式传输视频并与用户进行交互。
