In this part of the video, the speaker explains the importance of HDR (High Dynamic Range) in comparison to traditional screen resolutions like 1080p, 4K, and 8K. While resolutions deal with the number of pixels and sharpness of the image, HDR focuses on brightness, contrast, and color accuracy. There are various HDR formats that handle these aspects differently, and it’s crucial to understand them when purchasing a new TV. The speaker highlights the 65-inch Amazon Fire TV Omni that supports multiple HDR formats. Features like voice control via Alexa without the need for a remote and the ability to disable Alexa are also discussed. HDR allows for better detail in both bright and dark parts of an image and supports 10-bit color, offering over a billion color shades for more accurate color representation.

In this part of the video, the presenter discusses advanced TV features and HDR (High Dynamic Range) formats. They highlight the benefit of selecting specific colors, such as “candy red,” for more realistic visuals. Integration with smart devices, like a ring doorbell, allows users to see who is at the door without interrupting the show. The video explains different HDR formats, starting with HDR10, the most popular because it’s free for companies to use but limited by static metadata.

This format is also not widely supported by streaming services. A brief interruption by a phone call leads to a mention that the TV can handle Zoom calls with a compatible webcam.
Next, the video explains HLG (Hybrid Log-Gamma), developed by the BBC and Japan’s NHK for broadcasting. HLG allows a single signal to be sent that can display HDR or SDR depending on the TV’s capability, helping broadcasters save bandwidth. It uses 10-bit color and supports up to 4,000 nits of luminance. HLG content is available on BBC iPlayer, YouTube, and DirecTV, but is less common compared to other formats.
The segment then covers Dolby Vision, another popular HDR format, known for its high-quality dynamic metadata and 12-bit color which provides 68 billion colors and supports up to 10,000 nits of luminance. However, it requires manufacturers to pay licensing fees. Dolby Vision is available on various streaming platforms including Netflix, Apple TV Plus, Disney Plus, and Amazon Prime Video.
