With the booming development of audio and video industry, hd video data line categories emerge in an endless stream, not only many are listed as the standard of digital terminals, but also many wires are continuing to upgrade new standards.
For example, HDMI hd line, now has developed to version 2.1, and with 8K@60Hz, 4K@120Hz ultra HD output level, popular in the industry. Not only that, there is a lot of news about the new HDMI standard in the market.
HMDI LA has confirmed that it will release the HDMI 2.1A standard specification during CES 2022, which has caused a stir in the video industry.
At first hearing this news, you should apply and small you as curious: compared to the previous generation of HDMI2.1 standard, HDMI2.1A new standard exactly how "A"? Let's find out today.
In addition to the original HDMI2.1 standard, the new HDMI2.1a standard will add a small auxiliary feature -- SBTM function, which can automatically generate optimized HDR signals, and can better utilize the HDR function of the display without the need for manual Settings, which can greatly improve the user audio-visual experience.
However, the release of the new specification was accompanied by a mysterious operation in the HDMI forum, which was renamed.
In early December 2021, the HDMI forum that developed the interface specification cancelled the concept of HDMI2.0 and split HDMI2.1 into two sets of protocols: HDMI2.1 FRL and HDMI2.1 TMDS. HDMI 2.1 FRL is HDMI 2.1 and HDMI 2.1 TMDS is HDMI 2.0
In addition, HDMI LA recently published HDMI 2.1a standard specification overview, HDMI 2.1a content name is still HDMI 2.1, but the Chinese content name has been changed to HDMI 2.1a.
It is likely that an upgrade to HDMI 2.1 to HDMI 2.1a will follow, and the previous decision to name the specification HDMI 2.1 will be maintained.
To cancel an idea adds a lot of trouble. Especially for ordinary users who do not know, want to buy real HDMI2.1 standard wire later, may need to spend energy to study some ~~~
