The HDMI forum officially released HDMI 2.1 in November, 2017. Gamers around the world saw a new ray of hope in the new features announced in the latest specification – “Enhanced refresh rate features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video” (Ref: HDMI Forum releases v2.1 of the HDMI specification). These features include Variable Refresh Rate (VRR), Quick Mode Switching (QMS), and Quick Frame Transport (QMT).

HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transferring uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards, represented using one of several luminance/color-difference color spaces. We introduced HDMI 2.1 in our previous blog – HDMI 2.1: Channeling the GenX Audio Video Experience. In this blog we will discuss about evolution and key features of HDMI from v1.4 to v2.1.

In The HDCP 2.2 Authentication Process – an Introduction, we discussed why we need HDCP, and the basic steps of the HDCP Authentication Process. We noted that an advanced version of RSA is the underlying cryptography standard used during the Authentication and Key Exchange (AKE). AKE is the first step in the authentication protocol. Here we will continue exploring the next 3 steps of the protocol: Locality Check, Session Key Exchange (SKE) and Authentication with repeater.
Locality Check
This is an interesting checking mechanism introduced in HDCP2.X to ensure that the receiver and the transmitter are placed nearby. It prohibits sharing of HDCP2.2 protected content over a long distance.
