Philadelphia SMPTE & SBE18 Joint Meeting
October 13th, 2016
Hampton Inn & Suites
Karl Kuhn – Tektronix
Presentation: Implementation Challenges of 4K/UHD and New Testing Methodologies
The presentation will be a tutorial on what you need to know to meet quality and operational challenges when 720p and 1080i are just not good enough and the industry moves to 4K/UHD. We are now presented with broader questions and need to embrace new measurement techniques to maintain quality, staying away from the dreaded digital cliff.
Quad Link, 12G SDI and SDI over IP are new interfaces that present new technical challenges to maintain interoperability. We need to look at CRC, checksums and packet jitter/loss to make sure we have a clean interconnect. Moving into SDI over IP necessitates replacing Black Burst/Tri Level Sync with Precision Time Protocol (PTP). System stability is dependent on sending packets over a bursty and asymmetrical network. High Dynamic Range (HDR) and Wide Color Gamut (WCG) allow for more lifelike creative elements and bring along new technical issues to maintain interoperability and deliver content with high Quality of Experience scores.
