Following DVB’s announcent last week that it had agreed the commercial requirements for UHD-1 Phase 2 (see previous story), the Geneva-based standards body has revealed that these requirements do include a request for support for “progressively scanned sub-resolutions”, including a 1920 x 1080-pixel profile. This means that future Phase UHD-1 Phase 2 receivers would be expected to cope with an HDR transmission in 1080p. The move has proved contentious within DVB, since it associates the term ‘UHD’ with HD resolution levels. Generally, it is expected that such 1080p HDR transmissions would mainly be used by operators facing constrained bandwidth, with a view to the images being up-converted to 2160p on ‘4K’ TV sets.
