Behind the scenes in the world of 4K/UltraHD screens is a technological debate about the underlying high dynamic range (HDR) video formats – namely HLG (Hybrid Log-Gamma) and Perceptual Quantizer (PQ) variants (such as HDR10 and Dolby Vision). HLG was originally developed by the BBC and NHK, and later standardized by ITU-R, to solve for live video delivery with top-level HDR visual performance, low complexity and ease of implementation by program producers, broadcasters and service providers. PQ was originally developed by Dolby, and later standardized by SMPTE and ITU-R, to best represent the entire HDR capabilities of the human visual system whether for pre-produced content (motion pictures, episodics, etc.) or live events. In 2018, the SCTE•ISBE Standards Program released SCTE 247 2018, “High Dynamic Range (HDR) Video: System Requirements for Cable Phase 1 – Initial Deployment” to provide guidance to the cable industry. This session, featuring standards participants and leading technologists from CBS and MediaKind, will cover the background, current status and best practices for delivering HDR video over broadband distribution networks.
