Hãy viết đoạn tóm tắt về nội dung bằng tiếng việt kích thích người mua: Every HDR TV Format Explained

Pretty much every  and has the ability to decode , or high dynamic range, video. In most cases, HDR content looks better than non-HDR material, though an individual display’s ability to deal with the extra data can vary greatly. 

However, there isn’t just one HDR format. There are a number, including , HDR10,  and a couple of others. Few displays can decode them all, but all can decode the basic HDR formatting that all HDR content includes. Streaming services like Netflix and Amazon Prime Video, along with , can also support multiple formats, though often they only have one or two. 

The good news is, this isn’t a format war. All HDR displays can watch all HDR content. However, some of the formats have additional features that can be used by compatible displays for an even better image. Knowing what each of the formats does, and what to look for on your own TV, can be very helpful. Here’s everything you need to know

The basics

In CNET’s TV and projector reviews, both the capabilities of the TV itself and the way HDR is used in the movie or TV show have a greater impact on image quality than the specific HDR format. Which is to say, just because a display can read a “better” HDR format, doesn’t mean that display will look better than one that can’t read that format. Here’s a tour of the HDR landscape as it stands today.

• It’s not a full-fledged “format war,” it’s more like a slap fight.
• Multiple HDR formats can exist in a single TV.
• Everything supports HDR10, but many TVs and sources will also have at least one of the other formats.
• One format might look “better” than another on paper, but in the real world the biggest factors are the TV’s overall performance and the content itself.

Most new TVs have the ability to display HDR content, which has more detail in the bright and dark areas of the image, for a greater “dynamic range” compared to non-HDR content (i.e. pretty much everything you’ve ever watched). Older content is now referred to as “SDR,” or standard dynamic range. HDR content on an HDR TV can look far more punchy and vibrant than traditional content.

Right now — beyond Samsung — Panasonic, TCL, and Hisense are the biggest display brands supporting the format in the US. On the content side, there’s Amazon, Hulu, Paramount Plus, Apple TV Plus and Google. It’s unlikely HDR10 Plus will ever become the standard dynamic metadata HDR format, but it does give companies an alternative to the licensing fees of Dolby Vision.

Dolby Vision

• Widely supported.
• Potentially the best image quality of all the formats.
• Less content than stock HDR10.

Dolby Vision, like HDR10 Plus, can have dynamic metadata. Streaming services like Netflix, Amazon, Vudu and Apple TV Plus support it, and you can find it on some 4K Blu-rays. Aspects of Dolby Vision, like how it handles dynamic metadata and color, are optional for HDR formatting in the upcoming NextGenTV, aka . 

The issue with DV is that companies have to pay Dolby to use it. On the plus side to that, Dolby will then show them how to make their TVs look best when showing DV content. So for some companies, this is an easy way to get their TVs to look better than perhaps they would on their own. For larger companies (like certain Korean companies that begin with S), they don’t need such assistance and would rather dump money into their own HDR format, thank you very much.

There’s already wide TV support. Content is still in the early stages, however. If you can get the BBC’s iPlayer (whether you’re in the UK or using a VPN), that service has HLG support. DirecTV and YouTube also support HLG, but there’s just not a lot of content so far. Since it’s free, and fills an important niche, expect to see more HLG in the future. Some phones can record HDR via HLG, which you can playback on HLG-compatible displays.

Advanced HDR by Technicolor (SL-HDR1, 2 and 3)

• Not widely supported.
• Each “flavor” has its own niche.
• Potentially useful, but we shall see.

Technicolor’s Advanced HDR comes in multiple flavors: SL-HDR1 is similar to HLG, in that it’s fully backward-compatible with SDR TVs, allowing for one signal to rule them all; SL-HDR2 has dynamic metadata like HDR10 Plus and Dolby Vision; SL-HDR3 uses HLG as a base, but adds dynamic metadata.

Content is limited to some NextGenTV broadcasts. It’s unlikely it will get wide acceptance among streaming companies.

There can be only one. Or three. Or maybe five

A few things here are pretty easy to guess. HDR10 is the de facto base format. Nothing is likely to change that. Dolby Vision, with its wide industry support, especially on the content side, is likely to remain the “step-up” format. HDR10 Plus has increased in acceptance since its launch and is now a viable alternative to Dolby Vision.

, and it remains to be seen how much HDR content we’ll get with over the air content, though both HLG and Advanced HDR are viable options. 

In reality the long-term outlook is, to be honest, one of universal playback and irrelevant content format. Do you care if your TV is showing Dolby Vision or HDR10 Plus, as long as it looks as good as possible and just like the other format? Since a TV’s HDR performance is almost entirely based on its physical hardware, as long as the content looks good and can be shown properly, its specific format “language” doesn’t matter. Well, it doesn’t matter as long as your TV can speak it.
