Report ITU-R BT.2390-7 High dynamic range television for production and international programme exchange

Highlighted sections to read in this report:

• Section 1.1 Common misconceptions on HDR - ‘It is all about brighter pictures’ ’, ‘It is all about dynamic range’ , ‘It is all about bit-depth’, ‘It is primarily an image capture issue’, ‘It is primarily a display capability issue’, ‘It makes images look like paintings’
• Section 10 Mapping of SDR content into HLG and PQ – Guidelines for SDR to HDR and HDR to SDR conversions

Dolby Vision typically operates downstream of the HDR production standards defined in ITU-R BT.2390-7. Since Dolby Vision processes standardised HDR content (HLG and PQ) as input material, proper implementation of these ITU guidelines directly affects our downstream processing quality. The SDR-to-HDR conversion methods in Section 10 are particularly relevant, as they often form the technical foundation for Dolby Vision's dynamic metadata generation and tone mapping.
