Towards a Hierarchy of SDI DATA Rates

Once again our ability to capture and display images has leap-frogged our ability to transport, control and monitor them. — New ultra high definition formats, and high frame rates, require increasing data rates in image transport. Payload rates approaching 200Gb/s are required in support UHDTV-2 image structures at 120Hz progressive frame rate. — Building on the concepts presented in the paper “1080p50/60, 4K and beyond: Future Proofing the Core Infrastructure to Manage the Bandwidth Explosion” presented at the UHDTV: Ultra-High Definition Imaging Session of the 2012 SMPTE Annual Technical Conference, this paper introduces a hierarchical approach to increased SDI data rates, allowing affordable steps towards extended data rates, including those needed for UHDTV-2. — It describes progress in technical standards and technology development since the 2012 conference, for single-link and multi-link SDI interfaces operating at 6Gb/s, 12Gb/s and 24Gb/s using protocols which enable easy compatibility between data rates. It shows the performance that can be expected at these data rates, over copper and optical interfaces, and introduces coding concepts to improve the reliability of serial video.
