The new HDMI 2.1 standard will be introduced at CES 2022

HDMI standards are generally a bit confusing. But the exclusive new standard to be unveiled at CES 2022, the HDMI 2.1 standard, has complex details. The new standard appears to be supported by some TV and cable manufacturers, and could cause problems for users, such as the 120Hz PS5 or Xbox Series X games. In general, it can be said that the new HDMI 2.1 standard complicates things.

Let's start with its good features: HDMI 2.1a is a new version of the HDMI 2.1 standard, which is a new and important feature, namely Adds sound source mapping or SBTM. SBTM is a new HDR (High Dynamics Range) feature that outsources some HDR mapping to a content source (such as a computer or set-top box) alongside the audio mapping done by your TV or monitor.

SBTM is not a new HDR standard and is not intended to replace HDR10 or Dolby Vision. Instead, the technology is designed to help with existing HDR settings, optimize the content displayed on the screen by accessing the content source, or eliminate the need for the user to manually calibrate the screen to configure its contents. . Other uses for this new standard could be for when there is a mix of content types, for example for streamers (who can play an HDR game next to a window of black and white text), this feature can be any part of the content HDMI community notes that this will be possible for set-top boxes, game developers, and TV makers through operating system upgrades to the HDMI 2.1a standard and sound-based maps. Its source, depending on your design, add support for it. Given that the development of TV specs is slow, it seems that in most cases, users will not buy a new TV that supports the HDMI 2.1a standard (which we do not currently have). They will not receive the standard

but it's a good idea to look at the disappointing features of the HDMI standard. In addition to the unique features of the HDMI 2.1a standard, such as variable rate refresh rate, low automatic latency, and bandwidth to provide things like 10K resolution or 120Hz refresh rate, the SBTM will be an optional feature that manufacturers can support. And they can not, because this feature is not something they are required to use. This is because the HDMI Association and the HDMI Licensing Authority (the two organizations that define and license HDMI standards, respectively) implement the standards as a set that includes all previous standards.

According to TFTCentral, now that HDMI 2.1 is in place, the HDMI 2.0 standard will no longer be produced, according to TFTCentral; All new HDMI 2.0 ports must support the HDMI 2.1 standard, but can not take advantage of the new features of this standard. The HDMI 2.1a standard will work in a similar way; Once the standard is released, all new ports will be HDMI 2.1a certified according to the rules of the HDMI Licensing Authority, but will not support new features such as the new SBTM. The HDMI Association argues that their standards are always the same. Shapes work, and optional features allow developers to adapt to the performance they provide to users. For example, a typical gaming system might not need ports that support 120Hz VRR 8K gaming. Therefore, manufacturers can support these new standards with their unique capabilities according to the needs of their users. The company added that companies are required to list features that their hardware supports for customers so that they know what specific capabilities their companies have.

However, these kinds of arguments are not really acceptable. The whole purpose of the standards is to make them available to users on all devices by simplifying and optimizing these special features. The TFTCentral report notes that most manufacturers do not follow the HDMI Licensing Authority's recommendations for port labeling. At least for now, most TV companies still list HDMI 2.0 ports with the same name as HDMI 2.0, and use the HDMI 2.1 tag for ports that actually support newer features.

But the problem Importantly, under the rules of the licensing organization, these companies are not required to do so, and technically, despite the fact that this type of labeling is better for customer awareness, they should not continue to do so. So it is likely that some companies will soon launch HDMI 2.1 ports that do not offer any of the standard 2.1 or 2.1a features. This will make the future HDMI 2.1a standard and its new SBTM feature similar to the features of the previous version, if they did not use it at all.

new features of this standard will likely need to be purchased It has new hardware and cables, and even devices that claim to have HDMI 2.1a ports may not actually support them. However, we will have to wait and see what other information about the capabilities and features of this new standard will be released at CES 2022.
