UHD has been a buzzword these days and gained its popularity day by day. Besides UHD, you may also have heard about HDR, 4K and SDR, and UHD Blu-ray. These words must have confused you a lot. What is UHD? What is UHD Blu-ray? Is UHD the same as HDR? If not, what’s the difference between UHD and HDR? Or is there any difference between UHD and 4K? How about SDR? These questions must have blown your mind. If you have been tortured terribly by all of these questions, you can dive in this article. This article is packed with all the things you want to know about these questions, even more than that, including "burn-4k-uhd-iso-to-disc".

Part one: 4K vs UHD vs HDR vs SDR

Let’s start from the basic knowledge and figure out all these terms.

4K vs UHD: what’s the difference

One way to differ them is they originate different. The term 4K originally derives from the Digital Cinema Initiatives (DCI), a consortium of motion picture studios that standardized a specification for the production and digital projection of 4K content. 4K refers to resolution, which is stated in pixels. In this case, 4K is 4,096 by 2,160, and is exactly four times the previous standard for digital editing and projection (2K, or 2,048 by 1,080).

While UHD, short for Ultra High Definition, originates from a consumer display and broadcast standard. It is the next step up from what’s called full HD, the official name for the display resolution of 1,920 by 1,080. UHD quadruples that resolution to 3,840 by 2,160. It’s not the same as the 4K resolution made above – yet in practice, you will often see UHD used interchangeably with 4K, whether describing TVs, source devices, accessories or content. Therefore, when we say 4K, in most case, it also refers to UHD. From the above analysis, we can see that 4K and UHD is not exactly the same, but the differences between them don’t matter so much. More details refer to UHD vs. HD.

UHD vs HDR: what’s the difference

Since you already know the relationship between 4K and UHD, now let’s figure out UHD vs HDR, namely the difference between UHD and HDR. In fact, UHD and HDR are totally different technology terms. From the above information, you have already knew that UHD, short for Ultra High Definition, is used for resolution. While different than resolution, HDR stands for High Dynamic Range and is an expansion of the distance (contrast) between white and black in which bright whites can be captured and/or corrected so that they are more intense but don’t overwhelm the rest of the image that would normally be due to overexposure. What does this mean? This means images have more overall detail, a wider range of colors, and look more similar to what is seen by the human eye when compared to SDR. More details refers to UHD vs. HDR.

HDR vs SDR: what’s the difference

What is SDR? SDR is short for Standard Dynamic Range. It is a standard for video and cinema displays for now. Unluckily, SDR is limited by its ability to only represent a fraction of the dynamic range compared with HDR. Therefore, HDR preserves details in scenes where the contrast ration of the monitor could otherwise be a hindrance. SDR, on the other hand, lacks this aptitude.

To put it simply, HDR allows you to see more of the detail/ information and color in scenes with a high dynamic range while SDR doesn’t. More dtails refers to HDR vs. SDR.


What is 4K UHD Blu-ray?

Compared all these terms in groups, there is one left- 4K Ultra HD Blu-ray.

4K Ultra HD Blu-rays, as the name suggest, support 4K Ultra HD (3840 x 2160p) videos encoded using the High Efficiency Video Coding (HEVC) standard (also known as H.265). As it’s known to us all that streaming is more convenient for us, so people who desire the best possible picture and sound quality need 4K Ultra HD Blu-rays or 4K UHD Blu-rays. Why 4K UHD Blu-ray is so great? The reason comes down to one very simple, but important factor: Bit rate. To put it simply, the more data you can deliver, the better the picture and sound quality are going to be. 4K UHD Blu-ray uses 10-bit color depth and can cover the cover the full spectrum of the Rec.2020 color space. In terms of pixel, that’s approximately 8.3 million, four times what you get in Full HD (1920 x 1080p). By cramming such a giant volume of pixels into the same sized TV screens, the image becomes sharper and clearer. There is answer to How to Rip 4K UHD Blu-rays.
