To conform with the next generation of 12GSDI standards and 8K SHV Super Hi-Vision (7680x4320) test requirements, Chroma released its A223800 12G-SDI Signal Module. With 4 SDI signal output connectors supporting a variety of industrial SDI standards, and with more than 240 standard SDI timing parameters, one single module is capable to support up to 8K high resolution testing. Simultaneous output from multiple modules can accommodate any SDI test and measurement projects.
SD/HD/3G-SDI串行数字界面
SDI(Serial Digital Inter face)SDI (Serial Digital Interface) signal interface is standardized and announced by ITU-R BT.656 and the SMPTE (Society of Motion Picture and Television Engineers), it uses coaxial cables with a nominal impedance of 75 ohms for transmitting uncompressed digital component signals, and is widely adopted by the broadcasting industries.
SMPTE 259M是第一个发布的标准，它描述了模拟信号（例如NTSC和PAL）通过串行接口（通常称为SD-SDI）的传输，支持270 Mbps的传输速率。随着1080i和720p视频标准的高清晰度越来越流行，HD-SDI被发布以支持1.485 Gbps的数据速率，如SMPTE 292m中所述。当广播和其他视频产品供应商大量投资于同轴电缆及其硬件基础设施时，SMPTE宣布SMPTE 4.24亿标准，将带宽提高到2.97 Gbps，称为3G-SDI。它支持数字电影院的1080p和更高的分辨率，以获得更好的图像质量，并且也是过去几年实施最广泛的标准。
12G-SDI Serial Digital Interface
随着视频行业从SD（480p），HD（720p）转移到FHD（1920x1080）和UHD（3840x2160）的主流，现在正在进入Future SHV（7680x4320）ERA。在各种运动和大型活动广播中，12G-SDI界面起着非常重要的作用。
Chroma A223800 12G-SDI Signal Module is manufactured under SMPTE ST-2082 standards, supporting 12Gbps data rate and up to 12bit color depth with ITU-R BT.2020 Wide Color Gamut color space. The Video Payload Identification real-time editing function provides the end-user an even more flexible testing application.
HDR（高动态范围）图像
With the support to the High Dynamic Range image output, users can adjust HDR Metadata for HDR related testing from a various of built-in images such as gray scale, color bar, windows and many other patterns, for engineers to perform the Pre-Test before submitting for verification, ensuring that the product will meet the specifications.
