HDMI 2.1: technology and first practical experience Dynamic HDR formats Extended audio return channel Resolutions and refresh rates DSC compression method Variable refresh rate Conclusion Article in c’t 1 / 2021 read With the latest specification of the HDMI interface, one can really not speak of a snap shot: Although the beginning 2017, audio / video receivers and players – namely Microsoft’s Xbox Series – have only been available for a few months after televisions , Sony’s Playstation 5 and Nvidia’s RTX – 30 – graphics cards – available with HDMI 2.1. AMD’s Big-Navi series graphics cards have just started.

In defense of the HDMI forum behind the interface, it must be said that some of the innovations introduced with HDMI 2.1 compared to the last version 2.0b bring significantly more changes to the basic technical structure than the numbering suggests. On the other hand, HDMI 2.1 also includes functions that impatient system developers and manufacturers have already cleverly integrated into devices that use even older HDMI versions, some in a slimmed-down form.

Dynamic HDR formats These include the dynamic HDR formats Dolby Vision and HDR 10 +, where film studios create the desired image impression scene for Set scene and not only – as with the previously specified static HDR 10 – once for the entire film. Dolby and Samsung succeeded in converting the metadata from Dolby Vision and HDR 10 + as a workaround to “hide” in the video data stream, so that streaming clients and UHD Blu-ray players have been able to deliver HDR images in these formats to suitable TVs for years.

Samsung’s Galaxy Buds Pro will have a feature just like ‘spatial audio’ on the AirPods Pro

With its upcoming Galaxy Buds Pro, Samsung is planning to counter one of the differentiating features of Apple’s AirPods Pro (and now AirPods Max): spatial audio. Spatial audio crams an immersive, surround sound-like experience into a set of earbuds or headphones. And it accurately keeps the sound source anchored to your iPhone or iPad, so if you turn your head, you’ll notice that the audio stays in front of you. Wherever you move the device, that’s where it’ll sound like the audio track is coming from.

But Samsung seems to be readying its own take on spatial audio. As is becoming oddly common, the company’s mobile Galaxy Buds app has prematurely spilled some of Samsung’s latest earbud tricks. As noted by 9to5Google, an updated version of the app was found on Samsung’s servers with screenshots and features for the unannounced Galaxy Buds Pro. One of those new software capabilities is referred to as “3D audio for videos,” and the app says this will let you “hear vivid, immersive sound coming from all directions so you feel like you’re right in the scene when you watch videos.” Yep, sounds like spatial audio.

There’s also this note: “To get the best experience, keep your earbuds near your phone.” According to a teardown of the app, it looks as though Samsung will try to replicate the positional awareness / head-tracking aspect as well. Apparently, you’ll need a Samsung phone running Android 11 or newer for the feature to work. Other headphones (like those from Sony) offer 3D audio, but this is for music rather than movies from streaming apps.

The app also reveals that the Galaxy Buds Pro will have a “voice detect” feature that automatically enables transparency mode and lowers the volume of your audio when the earbuds sense that you’re speaking. Again, Sony has something similar to this on its 1000XM4 headphones where music immediately pauses when you start talking.

The Galaxy Buds Pro are expected to be announced in January alongside the Galaxy S21 series at the next Unpacked event.

Samsung Galaxy Buds Pro – Leaked renderings and full specification of TWS in-ear headphones. News: ANC and 3D sound

The Samsung Galaxy Buds wireless in-ear headphones have enjoyed well-deserved popularity since the first generation. Although of course (as befits Samsung) you could add a price that is too high, both Budsy and Budsy + regularly find themselves in quite good promotions. The last musical construction of the Koreans was a slightly different model in terms of construction, i.e. Samsung Galaxy Buds Live, but it looks like the company wants to return to a more classic look with the Samsung Galaxy Buds Pro. The first renders and elements of the headphones specification appeared on the network. What can we count on and when will the new “fleas” be presented?

An almost full specification of the next Samsung TWS wireless headphones has appeared on the network. The Galaxy Buds Pro will finally receive ANC. However, this is not the end of the news.

Samsung Galaxy Buds + headphones test. Endless gaming

In fact, it is currently unknown how much the Samsung Galaxy Buds Pro headphones will cost. We know when they will be presented (along with the Samsung Galaxy S series of smartphones 21 – so next month), we also know their appearance and specifications. The new headphones are finally to offer active noise reduction (ANC) as well as 3D surround sound known from competitor audio devices (Apple, Creative). The specification also includes such elements as gyroscopes, Dolby Atmos and SoundAlive (a list of pre-installed equalizer settings, dedicated to different types of environment).

Voice detection also seems to be an interesting option. Well, when we start talking to someone using headphones, the intensity of the music is reduced, and the Ambient mode will also be activated, amplifying the sounds coming to us from the outside. In addition, cooperation with BIxby and the gaming mode already known from Galaxy Buds Live will also be on board. The new Buds are to have one battery with a capacity 61 mAh for a “flea” and a case that is also a powerbank with additional capacity 472 mAh.
