The Ultra HD Forum has released the Phase B Guidelines for UHD, covering dynamic metadata, higher refresh rates, lower bandwidth requirements and next-gen audio. 

The Guidelines, released ahead of the start of NAB, aim to “de-mystify” five areas involving the future of UHD: Content-aware encoding, dual-layer HDR technologies, Dynamic HDR Metadata Systems (Dolby Vision and SL-HDR1), high-frame rate (100/120 frames per second), and next-gen audio (Dolby AC-4 Audio and SL-HDR1). 

Phase A Guidelines address technologies that were solidified in 2015 and 2016, then in the summer of 2017 we ran a survey with operators to guide the choice of the next phase of technologies,” said Madeleine Noland, chair of the Guidelines Work group.

She added that the aim is to “remain strongly focused on backwards compatibility,” and that Phase B will soon add workflows for all distribution systems, including over-the-air, MVPD and OTT.
