Paris Olympics 4K Dolby Vision: Will It Be Available?

Card No. 06·28271 · Updated · Standard formula, shown below

Yes, the Paris 2024 Olympics were broadcast in 4K with Dolby Vision HDR for select events, but not for every moment and not on every platform. The Olympic Broadcasting Services (OBS) produced a native 4K HDR signal using HLG (Hybrid Log-Gamma), and Dolby Vision was available on certain streaming services and devices that support it. This article explains exactly where you could watch in 4K Dolby Vision, what the technical setup was, and what it means for your viewing experience.

What Was the Official Broadcast Format?

OBS, the host broadcaster for the Olympics, produced the Paris 2024 Games in native 4K (3840×2160) with High Dynamic Range (HDR). The standard HDR format used by OBS was HLG, which is a broadcast-friendly HDR standard that doesn’t require metadata. However, Dolby Vision is a different HDR format that uses dynamic metadata to optimize the picture scene-by-scene. To deliver Dolby Vision, a broadcaster or streamer must take the HLG signal and convert it to Dolby Vision, or receive a separate Dolby Vision feed.

Which Platforms Offered Dolby Vision?

Dolby Vision availability for the Paris Olympics varied by region and platform. In the United States, NBCUniversal’s Peacock streaming service offered select events in 4K HDR, and some of that content was available in Dolby Vision on compatible devices. In the UK, BBC iPlayer and Eurosport provided 4K HDR coverage, but BBC used HLG, while Eurosport (via Discovery+) offered Dolby Vision on certain events. In France, France TV and Eurosport also provided 4K HDR, with some Dolby Vision support on compatible platforms.

It’s important to note that not all 4K HDR broadcasts were Dolby Vision. Many were HLG, which is the standard for live TV. Dolby Vision was more common on streaming platforms that could process the conversion, and even then, it was often limited to specific events like the opening ceremony, swimming, gymnastics, and athletics.

How Does Dolby Vision Work for Live Sports?

Dolby Vision is a dynamic HDR format that uses metadata to adjust brightness, contrast, and color on a scene-by-scene basis. This is different from static HDR formats like HDR10, which apply the same settings to the entire program. For live sports, this means that the bright sunlight of a stadium and the dark shadows of a tunnel can both be rendered with optimal detail, without the viewer needing to adjust their TV settings.

The production chain for Dolby Vision live broadcasts is complex. The camera captures a high dynamic range signal, which is then processed with Dolby Vision metadata. This metadata is embedded in the signal and transmitted to the viewer’s TV, which uses it to display the picture correctly. For the Paris Olympics, OBS provided a 4K HDR signal, and broadcasters like NBC and Discovery+ applied Dolby Vision conversion at their end.

What Do You Need to Watch in 4K Dolby Vision?

To watch the Paris Olympics in 4K Dolby Vision, you needed a few specific things:

  • A 4K TV that supports Dolby Vision. Most high-end TVs from LG, Sony, Samsung (2024 models), and others support Dolby Vision.
  • A streaming device or set-top box that supports Dolby Vision, such as an Apple TV 4K, Roku Ultra, or a compatible smart TV app.
  • A subscription to a streaming service that offered Dolby Vision coverage, such as Peacock (in the US) or Discovery+ (in Europe).
  • A fast, stable internet connection. 4K HDR streaming requires at least 25 Mbps, but for Dolby Vision, you may need more, especially for live events.

Even if you had all of these, not every event was available in Dolby Vision. The availability depended on the broadcaster’s production choices and the specific event. For example, the opening ceremony was a major showcase for 4K HDR, and many platforms offered it in Dolby Vision. But a preliminary heat of a less popular sport might only be available in HD.

Common Problems and Solutions

Many viewers experienced issues when trying to watch the Olympics in 4K Dolby Vision. Here are some common problems and what to do about them:

  • No Dolby Vision option: If you didn’t see a Dolby Vision option, check your TV’s picture settings. Some TVs have a separate HDR mode that needs to be enabled. Also, make sure you’re using an HDMI cable that supports HDMI 2.1, as older cables may not have the bandwidth for 4K HDR.
  • Picture looks dark or washed out: This can happen if your TV is not properly configured for Dolby Vision. Check that your TV’s firmware is up to date and that the streaming app is set to output Dolby Vision. You may also need to adjust the TV’s brightness and contrast settings.
  • Buffering or low quality: Live 4K HDR streaming requires a lot of bandwidth. If you experience buffering, try lowering the streaming quality or connecting your device via Ethernet instead of Wi-Fi.
  • Dolby Vision not available on all events: This is normal. Broadcasters only produced Dolby Vision for select events, often the most popular ones. Check the broadcaster’s schedule to see which events were available in 4K HDR.

Comparing Dolby Vision to HLG and HDR10

Dolby Vision is often considered the best HDR format because of its dynamic metadata. HLG, on the other hand, is designed for live broadcasts and doesn’t use metadata. HDR10 is a static format that is more common on streaming platforms and 4K Blu-rays. Here’s a quick comparison:

  • Dolby Vision: Dynamic metadata, 12-bit color depth, up to 10,000 nits brightness. Requires a license and is not supported by all devices.
  • HLG: No metadata, 10-bit color depth, up to 1,000 nits brightness. Compatible with most 4K TVs and set-top boxes.
  • HDR10: Static metadata, 10-bit color depth, up to 1,000 nits brightness. The most common HDR format, supported by all 4K TVs.

For the Paris Olympics, the native OBS feed was HLG. Broadcasters that offered Dolby Vision converted the HLG signal to Dolby Vision, which allowed for better scene-by-scene optimization. However, this conversion process can sometimes introduce artifacts or color shifts if not done correctly.

Is It Worth Watching in Dolby Vision?

For most viewers, the difference between HLG and Dolby Vision is subtle, especially on mid-range TVs. Dolby Vision’s dynamic metadata can improve the picture in scenes with high contrast, like a bright stadium with deep shadows. However, if you have a high-end TV with excellent HDR performance, you may notice the difference.

If you’re a sports enthusiast, the main benefit of 4K HDR is the increased detail and more vibrant colors. Dolby Vision adds an extra layer of optimization, but it’s not a night-and-day difference. If you don’t have a Dolby Vision-capable TV, you can still enjoy the Olympics in 4K HDR with HLG, which is what most broadcasters used.

Frequently Asked Questions

Was the entire Olympics available in 4K Dolby Vision?

No, only select events were produced in 4K HDR, and even fewer were available in Dolby Vision. The opening and closing ceremonies, swimming, athletics, and gymnastics were the most likely to be in 4K HDR. Check your local broadcaster’s schedule for specific events.

Do I need a special TV to watch Dolby Vision?

Yes, your TV must support Dolby Vision. Most mid-range and high-end TVs from 2020 onwards support Dolby Vision, but some budget models do not. Check your TV’s specifications to confirm.

Can I watch 4K Dolby Vision on my phone or tablet?

Some streaming apps supported 4K Dolby Vision on mobile devices, but it depends on the device and the app. For example, the Peacock app on an iPhone 15 Pro or an iPad Pro supported 4K Dolby Vision, but not all devices do. Check the app’s support page for details.

Why does my TV say it’s receiving Dolby Vision but the picture looks the same as HD?

This can happen if the streaming service is not actually sending a 4K HDR signal, or if your TV is not properly configured. Make sure you have a fast internet connection and that your TV’s HDMI input is set to enhanced mode if needed. Also, check that the streaming app is set to the highest quality.

Is Dolby Vision better than watching in 4K SDR?

Yes, Dolby Vision provides a significantly better picture than standard 4K SDR (Standard Dynamic Range). The HDR improves brightness, contrast, and color, making the image more lifelike. If you have a Dolby Vision-capable TV, it’s worth using.

Will the 2028 Los Angeles Olympics also have Dolby Vision?

It’s likely, as the trend is moving towards higher-quality HDR broadcasts. However, it will depend on the production choices of the host broadcaster and the platforms that carry the Games. As technology improves, we can expect even more events to be available in 4K HDR and Dolby Vision.
