SMPTE has two standards on the way regarding metadata pertaining to HDR, and it has a study group charged with studying the 4K eco chain and identifying gaps. Meanwhile, the DVB is due to discuss UHD TV Phase 2, which goes beyond static resolution.
“One of the most important issues will be HDR in environments where there are screens available with very high peak luminance,” said David Wood, chair of the DVB commercial UHD module. “Technical additions need to be made, starting with more bits per sample. Secondly, what we used to call the gamma curve will be called the OETF (Opto Electronic Transfer Function).
“The decision will be taken very soon on whether to include this feature in the UHD DVB Phase 2 spec intended for broadcasting in 2017, when the chips with the necessary memory bandwidth are available from manufacturers,” he added.
