HLG vs HDR10: Which Is Better

When it comes to high-quality pictures, HLG (Hybrid Log-Gamma) and HDR10 (High Dynamic Range) are two important codecs that improve the viewing experience. But how do they differ, and which should you select?

In this article, we'll look at five major differences between HLG and HDR10 and explain them clearly. Whether you're a technology expert or simply want to watch your favorite movies and shows in the highest quality, you'll find everything you need to make the right decision.

Part 1. What Is HLG and What Is HDR10?

HDR technology has changed the face of how we experience visuals with brighter highlights, richer colors, and better contrast. Among HDR formats, there are two major types: HDR10 and Hybrid Log-Gamma (HLG). They serve different purposes and cater to different audiences. Knowing about them can help you make a choice for which format you would like to use.

HDR10

HDR10 is the most commonly known standard for HDR content and includes static information. It employs metadata to establish brightness and contrast characteristics, resulting in a consistent view. HDR10 can support up to 10-bit color depth and 1,000 nits of peak brightness, making it ideal for streaming services, Blu-ray discs, and video games. Its open standard nature makes it compatible with a wide range of devices, but it lacks the dynamic adaptability of new formats like as HDR10+.

HLG

Hybrid Log-Gamma, or HLG, is an HDR format designed for broadcast TV. Unlike HDR10, it does not need metadata; thus, it can be transmitted in real time. The BBC and NHK jointly developed HLG, combining a logarithmic curve for highlights with a gamma curve for shadows to allow compatibility with both HDR and SDR displays. This format is useful for live broadcasting, where the absence of metadata simplifies delivery.

Part 2. Main Differences Between HDR10 vs HLG

When it comes to HDR formats, both HDR10 vs HLG offer different features. Let's find out their differences and see what makes them different.

1. Purpose

• HDR10: HDR10 is designed for pre-recorded content such as movies, TV shows, and video games. It delivers a consistent viewing experience because of the set parameters applied throughout the content for brightness and contrast.
• HLG: HLG is specifically designed for live broadcasts. Its main target is to provide real-time HDR content for sports, concerts, and news events.

2. Metadata

• HDR10: This mode depends on fixed metadata that sets a fixed range for brightness and contrast over the whole content. This can create consistency but is not responsive to changes in lightings over scenes.
• HLG: Unlike HDR10, HLG does not rely on metadata. It uses a hybrid approach in which standard gamma is utilized for SDR content, while logarithmic encoding is used for HDR. It can be easily integrated into the live broadcasting workflows.

3. Compatibility

• HDR10: HDR10 needs an HDR-supportive screen. It does not work natively on SDR screens, so viewing of the full visual effects can only be experienced through current HDR-capable TVs, monitors, and gadgets.
• HLG: One of its best attributes is backward compatibility-works well with both SDR and HDR displays, which is the main reason it finds applications in broadcasting to all kinds of audiences.

4. Color Depth

• HDR10: HDR10 is provided in a 10-bit color depth, thus rendering more than a billion colours. The outcome is natural and highly vivid visuals without colour banding or transition issues.
• HLG: HLG offers 10-bit color depth, resulting in stunning graphics. However, the actual output depends on the broadcasting infrastructure and device compatibility.

5. Adoption

• HDR10: HDR10 has been widely supported by platforms such as Blu-ray players, gaming consoles, Netflix, and Amazon Prime Video. The entertainment industry embraced it due to its open standard.
• HLG: While not as widespread with on-demand material, broadcasters such as the BBC and NHK are increasingly using HLG for live transmissions. Its ability to offer HDR material without additional metadata streamlines the production and delivery processes.
