What You Need to Know About HDMI 2.1 and CES 2022.

Many people might be asking themselves how the new HDMI 2.1a standard will impact them. The answer is that it won’t. This is because at this time it remains to be seen what specifics will be included in the final specification and that it is likely to take years before a significant number of devices will incorporate HDMI 2.1a features. Even so, there are a few features that are likely to become game-changers.

HDMI 2.1a comes with a single new feature called Source-Based Tone Mapping (SBTM). This new feature helps optimize HDR signals, by producing a baseline tone map for a source, and then compensating for it with a tone map of the HDR signal. This is a simple but powerful new feature that can help optimize a signal for a certain display.

Features of HDMI 2.1a

HDMI 2.1 makes it possible for an audio return channel to be added, among other features. One of the new features is called the Super Bit Mapping technology that Bluetooth has been adopted. However, HDMI 2.1a is a new version of SBTM, the Super Bit Mapping technology, which will require some additional features as well.

Drawbacks of HDR.

HDR is the buzzword of the moment in consumer electronics, as well as video content that is pushing the boundaries of what is achievable in terms of picture quality. HDR imaging is offering significantly better contrast and colors. However, there is a problem with the display.

With today’s technology, the display is only able to drive HDR content from the source device, even if the display itself is not capable of producing HDR content. If a projector is connected to a computer that is not equipped with HDR content software for the projector, the projector will be in HDR mode with no HDR content, resulting in a low-quality image. This is just one issue with the current display technology.

Role of HDMI LA.

The HDMI LA looks to solve this problem by introducing SBTM, which should allow a device to stream HDR content from a source that is below the display in terms of capabilities to the display itself.

This would enable HDR content to be displayed regardless of the capabilities of the source. This is something to look forward to when the technology.HDR10 is going to stay the format of choice for the market for a while. Source-based tone mapping is an interesting technology, but not something that will replace HDR10.

What do Verge reports say?

It says at CES 2022, HDMI 2.1a will be there but HDMI LA won’t be there. Organizers plan to hold the event and not CES 2021.

The HDMI 2.1 standard is expected to arrive in the market soon. This upgrade is expected to introduce some new features to the current HDMI hardware. Along with new features, the HDMI 2.1a standard will also reduce the required bandwidth for 4K visuals by a whopping 80%, in comparison to the HDMI 2.0 standard.
