If Hybrid Log Gamma, the solution in the HDR confusion?

Who already closer busy with HDR production, probably knows the current stumbling blocks. Whether one uses or Dolby Vision or even both on HDR-10th You need for each format on the end device actually own grading. And even if the domestic HDR-TV in the profile is switched and all clip flags indicated correctly one must first of all get at an HDR source. Over the Internet can thereby indeed different HDR-Streams next SDR, will be provided, for an existing television station infrastructure but this is too expensive as a rule. The Missing Link was previously a transmission standard which can spread both SDR and HDR signals over a single transmission channel. On the most beautiful it would be of course if normal SDR devices can interpret this format it right.Say Abwaertskompatibilitaet. And no less than this promises hybrid Log Gamma. Hybrid Log Gamma (HLG) is therefore likely to be at least the third major HDR format next HDR10 and Dolby Vision. And while HDR10 and Dolby Vision in the range Ultra HD Blu-ray and argue Internet distribution for supremacy, HLG should almost certainly make the grade in the field of television. The trick of the third format sounds as simple as it is ingenious hybrid Log Gamma uses the lower part of the transfer function, a typical gamma curve, while in the upper half of a log function is adhered. In the corresponding Wikipedia entry on hybrid Log Gamma this is quite well explained. A normal SDR-TV sees only the lower part of the curve, a whileHDR-TV can evaluate the whole graph showing. Currently equip just many manufacturers of HDR TVs to this profile for older models and Newcomers seems HLG profile now mandatory. In HEVC and HDMI 2b HLG profiles have been standardized also already. And if this HDR standard is established at the usual stations not excluded that it is in the medium term play in the Netzdistibution a bigger roles. After all, the studios tens of different grading will pay exactly the same film so reluctant for. For slashCAM readers could Hybrid Log Gamma still be interesting on the other side. Because Panasonic has already announced for its GH5 HLG profile that should come with the summer firmware update 2017th Thus  more infos at bei www.4kfilme.de deutsche Version dieser Seite: Wird Hybrid Log Gamma die Lösung im HDR-Wirrwarr?
