The quest for better-(not-just-more)-pixels is a big theme at this year’s IBC conference – primarily for television but with major implications for film and cinema too. For anyone thinking of buying a 4K/UHD TV, this is the session that tells you to wait until more than just the resolution of the big television sets improves.
Session chair Alberto Morello (RAI, Italy) calls this one of the “most interesting development in the evolution of video.” He singles out (more) pixels, (higher) frame rate and HDR (high dynamic range) as the things that “will give pleasure” to our viewers.
Touradj Ebrahimi (EPFL, Switzerland) goes up to the podium first to present an overview of the topic. He starts off by confessing to being an IBC virgin, but being ‘impressed’. Prof Ebrahimi stresses the importance of being able to measure to quantify improvements such as HDR.
Tests used Dolby Pulsar Display 42″, calling Dolby their “good friend” who “defined past, present and probably future” of high quality innovation. For content they “begged again” and Dolby provided that as well. Test material was shown sequentially and side-by-side in four different grades/mappings (4,000, 1,000, 400 and 100 nit). Appropriately one of the pieces of content was “Star Trek: Into Darkness”, but he wasn’t authorised to show that to us.
