The UK’s Digital TV Group (DTG) has launched what it claims is the world’s first UltraHD product testing zoo with a 4K HDMI interoperability event.


zooThe members-only occasion brought together retail 4KTVs from 10 different manufacturers, set-top boxes, an up-scaling Blu-ray player, an AV receiver and testing equipment from two providers. It also included 12 UltraHD 4K displays, all of which are currently available in retail, plus two set-top boxes and a reference STB design from a silicon vendor, with HDMI test tools supplied by Rohde & Schwarz and Quantum Data.

Participants tested different combinations of outputs and 4K resolutions, frame-rate and bit depth to build a picture of which HDMI features were supported. Device manufacturers and the DTG’s testing partners were joined during the day by observers from the UK broadcast platforms to assess the state of the technology’s development.

The DTG’s findings from the day are now being collated to investigate whether there are specifications or guidelines we can create to improve interoperability in the future. “This event marks the beginning in a new era of testing facilities at the Digital TV Group and we look forward to further collaboration with industry to create a thriving 4K Ultra HD ecosystem in the UK,” commented DTG chief technology officer Simon Gauntlett.
