Additional Notes - The Prime Video app is no longer available on TiVo Series 2, HD, HD XL, 160, 320, or on Premiere models issued by a cable or satellite provider. Streaming Video Quality - up to Ultra HD (Apple TV 4K); up to HD (all other models) Sound quality - up to 5.1 surround sound, Dolby Atmos. Amazon's app for the ATV is really terrible. There's a rumor that Amazon is planning on rehauling the interface. Hopefully they will also add Dolby Vision and fix the audio issues people have been having.

Streamingvideo has come a long way since Netflix began supplementing its DVD deliveryservice with web-based video-on-demand content in 2007. Back then, movies andTV shows were served up in standard definition, in the old-school 4:3 aspectratio, and with a highly compressed mono or stereo soundtrack. It was goodenough to enjoy watching reruns of my favorite 1980s shows (I’m an unapologeticfan of MacGyver and Airwolf), but if I wanted to watch a movie, I waited forthe disc. For streaming, it was all about the novelty of instant gratification,and the all-you-can-eat buffet of content available. And just as buffet-stylerestaurants aren’t known for their Michelin-star cuisine, streaming mediasimply couldn’t deliver the kind of cinematic experience that home theaterenthusiasts enjoyed from physical media. But in 2018, after more than a decadeof technological advancements, the quality gap between streaming media andphysical media has narrowed so much that even the most die-hard of AV puristsgobble up at least a portion of their entertainment from online sources. You nolonger need a spinning disc to enjoy 4K video with HDR (high dynamic range),and now even the latest object-based audio formats are streamable. Amazon’sPrime Video service is the latest to embrace immersive audio when the newPrime Original series Tom Clancy’s Jack Ryan which began streaming on August31st with a Dolby Atmos soundtrack.

Thenew series is the first Dolby Atmos content available from Amazon. PrimeVideo has supported Dolby Vision HDR video since 2016, but not Atmos audio.(Dolby Vision is a premium HDR format that uses dynamic metadata to makepicture adjustments on the fly, delivering a more vibrant overallpresentation.) The Jack Ryan series will be available in both Dolby Vision HDRand Dolby Atmos, but it’s not yet clear which devices will be able to deliverthe double Dolby experience when the show premiers. Dolby has stated that Amazon’s Fire TV and Fire TV Cube streaming devices will supportAtmos on Prime Video, but neither device supports Dolby Vision HDR. No otherdevices have been confirmed, but Dolby did say in a recent press release thatAtmos will be coming to Prime Video on “a variety of other compatible devicesincluding TVs, sound bars, and home theater systems.” One very likely candidateis the latest Apple TV media streamer, which can deliver both Dolby Vision(currently) and Dolby Atmos (after a firmware update this fall). The Xbox One gaming consoles from Microsoft also support Atmos,and will be getting Dolby Vision support via a firmware update. LG’s latestOLED TVs support both Dolby formats. For the record, Amazon has indicated that JackRyan will also be available in the competing HDR10+ video format on compatible devices,such as Samsung TVs.

Withthe arrival of Atmos content on Prime Video, Dolby is expanding the reach ofits flagship audio format, which is already available on a small but growingnumber of titles on Netflix and Vudu. Hulu and HBO have not yet adopted DoblyAtmos (nor Dolby Vision), but I wouldn’t be surprised to see them follow thetrend. Amazon’s Greg Hart, Vice President of Prime Video, said that

Amazonis committed to delivering immersive and compelling content to… Prime Videomembers around the world,” and that “Dolby Atmos and Dolby Vision willenhance the action-packed scenes in Tom Clancy’s Jack Ryan, and makeviewers feel like they are at the center of the story.”

The series followsthe exploits of Jack Ryan, an up-and-coming CIA analyst whose adventures we’veseen before on the big screen, in films like The Hunt for Red October andClear and Present Danger. (John Krasinski, who plays the protagonist inthis new series, is the fifth actor to portray Ryan on screen, after AlecBaldwin, Harrison Ford, Ben Affleck,and Chris Pine.) In the new Prime Original series, some suspicious banktransfers lead the protagonist to leave the relative safety of his desk job andbecome entangled in an international terrorist threat. Amazon ordered a secondseason of the series back in April, over four months before the first season’spremier of August 31st.

Has Streaming Quality Caught Up with Physical Media?

Nowthat streaming services are offering leading-edge technologies like Dolby Atmosand Dolby Vision HDR, have they finally caught up to the audio-visual qualityavailable from Ultra HD blu-ray discs? Not quite. The version of Atmos used bystreaming services is based on Dolby Digital Plus, which uses lossy datacompression to reduce file size. Dolby Atmos on Ultra HD blu-ray discs is builtupon Dolby True HD, a lossless format that delivers the original,full-resolution soundtrack in its entirety. Similarly, the video compressiontechniques used by streaming services can introduce noise and video artifacts.But it’s not hard to imagine a time in the not-so-distant future when theperformance gap between physical and streaming media will go from narrow tonon-existent.

Dolby has played a key role in the development of HDR for both commercial cinema and home theatre applications. From a home entertainment perspective, the company’s most important contribution has been the advanced form of HDR (High Dynamic Range), known as Dolby Vision.

Dolby Vision has the potential to improve consumers’ viewing experience by constantly optimising the way their TVs deliver HDR pictures – just as the rival HDR10+ format does. It also gives content producers more control over how their HDR programming appears on TVs. And it's slowly coming to smartphones and tablets, too: it's supported on most iPhones now, including the iPhone 12 and iPhone 12 Pro. The iPhone 12 Pro can even film footage in Dolby Vision.

It was originally widely assumed that Dolby Vision hardware (screens and Ultra HD Blu-ray players) needed to carry a dedicated chip. However, it is now possible to add Dolby Vision support via a firmware update to devices with sufficiently powerful processors.

The industry standard HDR10 format is free for manufacturers to use, but Dolby Vision requires the payment of a licence fee. So what’s so special about Dolby Vision that hardware brands and consumers would pay extra for it? Quite a bit, actually.

What is Dolby Vision?

The most significant advantage of Dolby Vision HDR versus HDR10 is the addition of dynamic metadata to the core HDR image data.

This metadata carries scene-by-scene instructions that a Dolby Vision-capable display can use to make sure it portrays the content as accurately as possible. Dolby Vision-capable TVs combine the scene-by-scene information received from the source with an awareness of their own capabilities in terms of brightness, contrast and colour performance.

With HDR10 content, your HDR TV only receives static metadata; relatively basic ‘global’ information on the content being shown that applies to the entire film or TV show.

It can’t provide a display with updates on how each specific shot or scene should be shown. Nor does HDR10 carry the same facility for continually optimising the picture to the capabilities of the screen it’s showing on.

Dolby Vision is built on the same core as HDR10, which makes it relatively straightforward for content producers to create HDR10 and Dolby Vision masters together. This means that a Dolby Vision-enabled Ultra HD Blu-ray can also play back in HDR10 on TVs that only support that format.

Dolby Vision allows content producers to have either one or two ‘layers’ of data; one carrying just an HDR signal, the other carrying a standard dynamic range (SDR) signal. This single HDR/SDR workflow approach makes Dolby Vision a convenient tool for content creators and broadcasters to use.

Another advantage of Dolby Vision is that the metadata is embedded into the video signal, meaning it can run across ‘legacy’ HDR connections as far back as version 1.4b. Despite only using static metadata, HDR10 requires HDMI 2.0a compatibility.


On the content production side, Dolby Vision seems more focused on pushing HDR to its technical limits. The minimum specification for Dolby Vision mastering requires the use of reference monitors with a contrast ratio of 200,000:1, peak brightness of 1000 nits, colour range ‘approaching’ the Rec 2020 standard, and support for the SMPTE ST-2084 HDR format.

However, Dolby has also developed a reference ‘Pulsar’ monitor that provides an 800,000:1 contrast ratio, a peak brightness of 4000 nits, and the so-called P3 colour range used in digital cinema applications.

Given its greater creative palette, and the drive towards delivering consumer TVs with ever greater brightness (some of Samsung’s 2019 TVs claimed to hit 4000 nits), it’s certainly tempting to see this Dolby Pulsar monitor as a glimpse of HDR to come.

Does Dolby Vision deliver better pictures?

Our initial experience of Dolby Vision in the UK was limited to a few Netflix and Amazon streams, plus a handful of Dolby Vision film clips viewed on LG Dolby Vision TVs, and our impressions were that Dolby Vision makes a difference for the better.

In a head-to-head comparison of Dolby Vision and HDR10 demo clips, Dolby Vision images appeared to contain more tone definition in bright areas; more balanced, nuanced and natural colours right across the spectrum; better contrast range management; and a greater sense of detail – presumably a side effect of the colour and light management improvements.

However, we've since done a head-to-head comparison using two discs: Despicable Me and Power Rangers in 4K Blu-ray, and the results were unexpected. With Despicable Me, the Dolby Vision effect came across looking rather flat and contrast was more subdued; it was surprisingly less vibrant and spectacular than the HDR10 version of the film.

The Dolby Vision version of Power Rangers, however, is even punchier and more vibrant than the HDR10 alternative, with more nuance thanks to the extra detail revealed in the brightest and darkest areas of the image. It’s not utterly transformative, but it is quite clearly better.

Since Dolby Vision is applied on a disc-by-disc and frame-by-frame basis, it could well be that Despicable Me just isn’t a particularly good example of its implementation, while Power Rangers is more typical of what you can expect from the format.

The small sample size means we can’t draw absolute conclusions on this matter, but what's clear that, when implemented correctly, Dolby Vision can produce marked improvements on an already-impressive HDR10 presentation. We can only take each disc on its own and see how well Vision performs on a case by case basis.

How can you watch Dolby Vision?

With more and more 4K Blu-ray discs with Dolby Vision hitting the shelves, an increasing number of 4K Blu-ray players now come with Dolby Vision support as standard, including top end five-star players like the Cambridge CXUHD and Panasonic DP-UB9000 and the 2018 Award-winning Sony UBP-X700, together with upcoming 2019 models from Panasonic and Sony.

It’s a more complicated story when it comes to TVs. Not all manufacturers support Dolby Vision and those that do don't implement Dolby Vision on all their models. For the likes of LG and Sony it tends to be supported on more premium ranges.

Panasonic's GZ2000 flagship 2019 OLED TV was the first Panasonic set to ever support Dolby Vision. The manufacturer previously nailed its colours to the mast of rival format HDR10+ but it appears to be softening its stance. This goes for its 4K Blu-ray players too. For 2020, Panasonic's flagship HZ2000 will also support Dolby Vision, as well as HDR10+.

Philips also decided to offer both HDR10+ and Dolby Vision support on its 2019 OLED TV ranges, OLED 804 and OLED 854. Previously the company only offered HDR10+. The just announced OLED805 and OLED855 TVs for 2020 will support it too.

Sony continues its TV support into 2020 with its headline premium 8K and 4K TVs supporting the format, while LG also continues to be fully onboard the Dolby Vision bandwagon with its 2020 TVs.

Dolby Vision is also available via the Apple TV 4K, Google Chromecast Ultra and, more recently, the Amazon Fire TV Stick 4K, while in the US, Vizio, Hisense, LeEco, Philips (which has a different owner to Philips in Europe) and TCL all already have Dolby Vision TVs on sale or set for launch.

And which brands don't support Dolby Vision?

Samsung is the biggest hardware brand that doesn’t yet support Dolby Vision on any of its products.

There's the issue of adding to manufacturing costs with the licence fee, and Samsung has stated that it trusts its own TV processing, and the capability of its own hardware, arguing that it optimises HDR10 images efficiently enough without Dolby Vision.

However, that doesn’t take into account Dolby Vision’s potential for content creators to have more say over how their content appears.

But the main reason Samsung isn't currently courting Dolby Vision is because it's backing a royalty-free dynamic metadata HDR system called HDR10+.

Developed by Samsung, and with 20th Century Fox and Warner Bros as partners to license HDR10+ to other manufacturers, it's a direct rival to Dolby Vision. The format has started to appear on a small number of 4K Blu-ray titles, including Bohemian Rhapsody and Alien 40th Anniversary. Amazon Prime Video is also using this technology on a limited amount of content.

Samsung claims there are over 1000 titles available in HDR10+ on Amazon, including The Grand Tour but currently, compatible TVs are unable to flag up when they're receiving such content. This is set to change on a number of models though.

While Dolby has gone out of its way to dismiss talk of any possible format war with HDR10, positioning its technology as a ‘value added’ proposition in relation to HDR10 as opposed to a direct competitor, HDR10+ is certainly a rival to Vision.

What Dolby Vision content is available?

A number of major film studios including Lionsgate, Sony Pictures, Universal and Warner Bros - have all released Dolby Vision UHD Blu-rays.

Despicable Me and Despicable Me 2 had the distinction of being the first 4K Blu-ray titles with Dolby Vision to hit the market. Not the most scintillating start, but it’s picked up since then.

Existing titles include Solo: A Star Wars Story, Avengers Infinity War, Jurassic World - Fallen Kingdom.

Things are a bit more advanced on the streaming side. In the UK, both Netflix and Amazon Prime Video support Dolby Vision HDR streams, while in the US they are joined by VUDU.

Amazon Prime Drops Support for Atmos and Dolby Vision   Page ...

Netflix shows that support Dolby Vision include Marvel's Daredevil, Jessica Jones, Luke Cage and Iron Fist, as well as other Netflix Originals such as Lost in Space, Altered Carbon, Santa Clarita Diet, Stranger Things series two and Dynasty.

Meanwhile, Amazon Video is much more sparse when it comes to Dolby Vision, with only a limited amount of content available, including Jack Ryan and a handful of Sony Pictures films such as After Earth, Fury, Elysium, Men in Black 3 and The Amazing Spider-Man 2.

More recently, Rakuten has partnered up with Dolby and LG to bring Dolby Vision (and Atmos) movies to its film rental service. Titles include modern blockbusters such as Blade Runner 2049 and Baby Driver and older films such as Bad Boys II and The Amazing Spider-Man.

The PC game Mass Effect: Andromeda was the first game to support Dolby Vision, heralding a whole new outlet for the format. The Xbox One X and S both support Dolby Vision following a software update, but it's unlikely Dolby Vision support will ever arrive on Sony's PlayStation 4.

Dolby Vision can also be applied in a live broadcast environment – though we’re not aware yet of any broadcaster announcing plans to use it. Besides, another format, Hybrid Log Gamma (HLG), is currently the default format used with 4K broadcasts.

What about Dolby Vision on mobile phones and tablets?

Fancy enjoying Dolby Vision videos while on the bus or train to ease your daily commute? There is now a small selection of smartphones that let you do just that.

Has Amazon Prime Video Dropped Dolby Atmos? AVForums

The LG G6 was the first smartphone to come equipped with Dolby Vision HDR. Apple dominates the list, with the vast majority of its most recent handsets supporting the format, including the Apple iPhone 11, 11 Pro, X, XS, XS Max and XR.

Currently, the only tablets compatible with the format are second and third generation Apple iPad Pros.

We can expect Dolby Vision to come to more future Android phones courtesy of Qualcomm's December-announced Snapdragon 865 phone chipset, which promises support for 8K and Vision video capture, bringing a huge quality boost to phone camera footage.

So what's this we're hearing about Dolby Vision IQ?

Announced at CES 2020, Dolby Vision IQ is essentially a development of Dolby Vision, designed to optimise how Vision content looks according to the brightness of the room your compatible TV is in.

This should mean that Dolby Vision content, regardless of its overall brightness, is just as intelligible when watched in a bright room as in a dark room.

To do this, Dolby Vision IQ uses the dynamic metadata from Dolby Vision, as well as light sensors inside your TV, to dynamically adjust the HDR picture based on the content and ambient light conditions in your room.

If you switch from bright live sport to a darker TV show, the TV will adjust accordingly for the optimum picture. The promise: to deliver 'a perfect picture in your room at every moment'.

What's the future of Dolby Vision?

It's of course not just consumer products that support Dolby Vision. The UK's first Dolby Cinemas offering Dolby Vision and Atmos are now open, proving yet further that the company is eager to get Dolby Vision in front of more eyes. The technology is now well established and well supported in the AV industry, and, with Dolby Vision IQ now a thing too, looks to only get better and better.

There's no doubt the current HDR landscape is a little rocky, especially when you throw HLG (the broadcast HDR TV format), the LG-only Advanced HDR by Technicolor and, more crucially, Vision's main rival, HDR10+, into the equation.

Unfortunately, there's a chance it could get more confusing as the new formats and standards settle. But fear not - we'll be on hand to help you cut through the jargon.
