delegates from the Advanced Television Systems Committee, CEA, NCTA, and the Society of Motion Picture and TV Engineers was disclosed by a senior executive at Harmonic, who described the lack of HDR standards as perhaps Ultra HD’s “biggest roadblock.” Of the groups we canvassed for comment on the meeting and the lack of HDR standardization that brought it about, only ATSC President Mark Richer responded with a statement that addressed the HDR issue, if only in the most general terms. “HDR is one of the many issues being considered in the development of ATSC 3.0,” Richer said. “The industry recognizes that there are many technical parameters in addition to total pixel count that determines perceived quality. Since ATSC is focused on the standardization of the transmission to the home, a lot will depend on the plans of the production and consumer electronics industries.” At the NAB Show, the chairwoman of the ATSC’s “S34” specialist group responsible for ATSC 3.0’s audio and video codecs, closed captioning and its other “applications and presentations” said her group would “definitely” study HDR, but she said little more on the subject (CD April 8 p11). Brian Markwalter, CEA senior vice president-research and standards, declined comment on HDR standards. Recently, he said there was much industry “discussion” taking place about getting together this year and devising more up-to-date Ultra HD definitions, logos and certifications than was possible when CEA adopted its Ultra HD nomenclature in fall 2012, but whether that update effort would involve studying HDR standards remains to be seen. At NCTA, “we don’t really have any comment on the HDR standards issue as it is early on with this topic,” said a spokeswoman by email.
