After having carefully analysed the latest move of the HDMI Forum, that is the decision to merge HDMI 2.0 and HDMI 2.1 leaving the manufacturers the burden of specifying its functions, interesting innovations come in the innovation front.
We are talking about HDMI 2.1a, standard that should enrich the already abundant catalogue of features put on the plate by the HDMI 2.1. In this regard, we welcome the first news on this issue, a few days after CES 2022, and concern a functionality that could revolutionize our current approach to HDR. As reported by the source, an information note on this technology appeared on the official HDMI.org website, where you can read that “the Source-Based Tone Mapping (SBTM) is a new function of the HDR that allows you to perform a The SBTM is particularly useful in scenarios where HDR and SDR content are combined together in a single screen, such as image in the image or program guide with an integrated video window. SBTM technology also allows PCs and gaming devices to automatically produce an optimized HDR signal to maximize the use of the display HDR capabilities without user manual configuration on the source device.”
The most interesting part of the speech is definitely the one where you mention the possibility of mixing in a screen content with and without HDR. For example, we think of a game in window mode, or the coexistence of unoptimized material on screen for HDR. In short, it is clear that the drive to strengthen this standard is still strong, but the discussions of the last few days are still bound to leave it long.
