The HDMI Forum Releases Version 2.1a of the HDMI® Specification

The HDMI Forum has published Version 2.1a of the HDMI Specification which is available to HDMI 2.x Adopters. One of the highlights of this update is the addition of a new feature, Source-Based Tone Mapping (SBTM).
Source-Based Tone Mapping (SBTM) is a new HDR feature that allows a portion of the HDR mapping to be performed by the Source device instead of the Display device. SBTM is especially useful in cases where HDR and SDR video or graphics are combined together into a single picture, such as picture-in-picture or a program guide with an integrated video window. SBTM also enables PCs and gaming devices to automatically produce an optimized HDR signal in order to maximize the utilization of the display’s HDR capabilities without manual user configuration of the Source device.
