What’s Complicated HDR through Technicolor? – CNET

Technicolor has been a part of the Hollywood panorama for over a century, and now it is aiming for prominence in your house too. Its weapon is a brand new structure referred to as Complicated HDR.

The corporate faces some sturdy festival on your front room. High dynamic range (HDR) delivers the most efficient house video photographs to be had lately, boosting distinction and dad. Completed smartly, particularly on a pleasing TV, it supplies a a lot more visual get advantages than 4K resolution. 4K HDR is mainly the way forward for tv, which is why Technicolor (and reputedly everyone else) has an HDR structure.

The industry-standard HDR10 structure is just about all over the place, to be had from a couple of streaming services and products together with Netflix and Amazon, 4K Blu-ray in addition to TVs as cheap as $280. 3 different HDR codecs also are to be had: Samsung’s HDR10+, hybrid log gamma (HLG) and naturally Dolby Vision.

HDR10 vs. Dolby Vision vs. HLG: How do HDR formats compare?

A couple of years in the past I visited Technicolor during the early days of Advanced HDR, however now the structure is if truth be told to be had in TVs, particularly the ones from LG. Does Complicated HDR have sufficient distinctive options to compete with the likes of Dolby Imaginative and prescient and HDR10+? Does it have the breadth of give a boost to of HDR10? (Spoiler: now not but). Does it have some distinctive and engaging sides plus plenty of letters and numbers? You wager! Let’s dive in.


Brace your self: the time period “Complicated HDR” if truth be told covers a bunch of Technicolor’s HDR technologies. For you at house it is 3 other HDR codecs. There may be additionally some tech advisable to broadcasters and vendors (like Netflix or Vudu). Listed below are the fundamentals:

SL-HDR1: Single-Layer HDR1 is in all probability probably the most fascinating. It is necessarily an SDR (normal dynamic vary — call to mind it as common TV) sign, however with HDR knowledge “hidden” inside of. This implies a unmarried broadcast may just paintings with older SDR TVs, and likewise supply more moderen HDR TVs with HDR content material. 

This unmarried flow lets in for more effective manufacturing, like at a are living carrying match. A unmarried manufacturing truck may just broadcast each the HDR and SDR program with minimum effort. The advantages for broadcasters are evident: More practical manner inexpensive. Additionally, it really works on each TV. The drawback is that it does not somewhat have the image high quality attainable of the opposite choices. Nonetheless, it is probably higher than SDR. That is very similar to what is promised through Hybrid Log Gamma (HLG). SL-HDR1 been authorized for inclusion within the upcoming ATSC 3.0 broadcast standard.


The trail to SDR and HDR in a single SL-HDR1 sign. The highest is the content material advent, the ground is what your TV will do with it. The SDR content material is routinely constituted of the HDR sign.


SL-HDR2: It is a complete HDR sign, the usage of HDR10 as a base. Added on best of this is dynamic metadata, so each and every scene, and even each and every symbol inside of a scene, can glance its very best for your TV. It is a step up over HDR10’s static metadata that has one world HDR “glance” in keeping with display or film. HDR10+ and Dolby Imaginative and prescient even have dynamic metadata. The drawback right here, like the ones codecs, is that it is HDR or not anything. A SDR TV would do not know what to do with the sign. This, in fact, is not a subject with streaming or 4K Blu-ray, which will have a SL-HDR2 flow at the side of an SDR flow. With broadcast, the loss of SDR makes it a non-starter.

SL-HDR3: This makes use of HLG as a base, however provides metadata on best, probably making improvements to the picture high quality of that structure. That is nonetheless within the early phases, so we’re going to most probably listen extra about it someday.

That is numerous letters and numbers. OK, 5 letters and 3 numbers, however nonetheless. The principle factor you must remove is that SL-HDR1 is backwards appropriate with non-SDR TVs. That is what makes it just right for broadcast. SL-HDR2 has dynamic metadata, so it probably provides the image high quality enhancements of the extra complicated HDR codecs like HDR10+ and Dolby Imaginative and prescient. SL-HDR3 remains to be within the early phases, and is tied to HLG which itself is within the early phases, so it isn’t value being concerned about for now.

Additionally, and type of similar, the “Complicated HDR” banner from time to time additionally comprises Technicolor’s proprietary SDR-to-HDR conversion procedure referred to as Clever Tone Control. For more information on that, take a look at this explainer.

The place are you able to see it?

With any video structure, there are two major questions: is there content material to be had now, and are you able to show that content material for your TV? The fast solution is not any to the primary phase, and theoretically sure to the second one (as soon as content material turns into to be had).

There’s recently no Complicated HDR content material to be had in any of its 3 flavors. There’s some check pictures, just like the Dodgers recreation you notice on the best, however in the case of “sit down down and watch a brand new display on my TV,” not anything but. This would exchange as soon as ATSC three.zero arrives round 2020. If we begin to see ATSC three.zero announces the usage of SL-HDR1, it isn’t a stretch to suppose we would see different flavors of the structure in wider use, like SL-HDR2 on a streaming platform, as an example. It is also imaginable we’re going to see SL-HDR2 on Extremely HD Blu-ray discs, however there is not any content material but.

Although they have got a overdue begin to the HDR race, the ace up Technicolor’s sleeve is LG. You’ll be able to purchase an LG TV lately, in all probability you even purchased one in every of theirs final yr, that may already decode Complicated HDR. This is a part of a technique through LG to hide as many structure bases as imaginable, very best described through their Senior Director of Product Advertising, Tim Alessi:

“LG’s method has been to provide the widest give a boost to for HDR codecs with the intention to supply a cinematic revel in in the house, and take away any attainable uncertainty about compatibility. As an example, we had been a few of the first to introduce give a boost to for the top class viewing revel in of Dolby Imaginative and prescient, and upload give a boost to for HLG along with HDR10.  We see inclusion of Complicated HDR through Technicolor as a continuation of that philosophy.”

LG TVs do not give a boost to HDR10+, in fact, however no marvel there as a result of that structure used to be mainly created through arch-rival Samsung, partially to make up for a loss of Dolby Imaginative and prescient give a boost to on Samsung TVs. 

LG’s OLEDs, and shortly their UHD LCDs, even have a “Technicolor Knowledgeable Mode” as probably the most image presets, which LG claims will make the picture glance as shut as imaginable to the way it did within the Technicolor mastering suites. In CNET’s review of the C8 OLED TV, that mode did supply a particularly correct image with each SDR and HDR content material, in order that’s cool.

Past LG, Funai, which sells TVs underneath the Philips emblem and several other others, has introduced give a boost to for Technicolor Complicated HDR of their 2019 fashions.

Even supposing that is only one, quickly to be two, firms, that is nonetheless a large put in and rising base. That is a a long way higher place than Technicolor used to be in two years in the past: bobbing up with a structure and seeking to store it to content material creators and not using a manner for shoppers to look at it.


So can we see extra firms be offering Technicolor Complicated HDR? Samsung, pushing their HDR10+ structure, turns out like a non-starter. Vizio has had Dolby Imaginative and prescient from the start, whilst Sony used to be overdue to Dolby Imaginative and prescient however it is catching up this yr. Both corporate may well be subsequent. 

Complicated HDR has been incorporated within the draft of the impending broadcast normal in China. If it is followed, may just that imply wider availability from Chinese language TV firms, like TCL or Hisense? Most likely.

Technicolor claims we’re going to see extra TVs with interpreting integrated on the IFA industry display in September. Additionally they advised us we would listen about much more firms supporting Complicated HDR at CES 2019 in January.

Joseph and the Superb HDR Dreamcoat

Technicolor’s Complicated HDR is fascinating sufficient, however at this degree it is a long way from essential on your subsequent TV. And its luck is hardly ever confident.

The true query now could be whether or not Technicolor can persuade content material creators that Complicated HDR’s choices be offering sufficient of an growth in image high quality, relief in manufacturing prices or each, in comparison to different HDR strategies. In that manner it is in large part out of our, the patrons, fingers. We will have to attend and notice the way it all shakes out, particularly with ATSC three.zero across the nook.
