  • Panasonic has revealed to us that all 2016 4K TVs from the DX750, and up, are to receive a software update making them compatible with the Hybrid Log Gamma (HLG) format, which will be the prevalent standard used in High Dynamic Range (HDR) video delivery in broadcast TV from the BBC and NHK, among others, and likely industry wide.
    This means that owners of the TX-65DX902B, TX-58DX902B, TX-58DX802B, TX-50DX802B, TX-65DX750B, TX-58DX750B and TX-50DX750B will all able to get in on the action. Going forwards, all of Panasonic’s 4K HDR range will feature HLG support, out of the box.

    Hybrid Log-Gamma (HLG) a version of HDR that was jointly developed by NHK and the BBC. HLG has a number of advantages but the main ones are that it is royalty-free and compatible with Standard Dynamic Range (SDR) displays and has already been trialled via the iPlayer by the BBC, using clips of Planet Earth II.

    Hybrid Log-Gamma archives this backwards compatibility by combining two different curves to create a third curve. This hybrid curve is composed of a traditional gamma curve, which has been used for decades, for the lower or darker part of the signal and a logarithmic curve for the higher or brighter part of the signal.
