Basically, if you want to run video at 60Hz, you must run a reduced color sampling rate. The frame rate speed of video effects the color sampling rate we can use. Color depth can be produced in 8, 10, 12, and 16 bit rates. HDMI 2.0 includes support of BT.2020 colorimetry with 10-bit color depth or higher. This is obviously a considerable jump in data that hardware pieces must also handle.Ĭolor Space is another consideration that must be managed. Currently, the highest rated HDMI cable is the 2.0 standard, supporting 18 Gbps. To deliver 4K resolution, you would increased the required data rate by a factor of four.
When transmitting 1920x1080 video at 60fps, a data rate of 4.46 Gbps required. Now, let's dig into some of the design challenges. Very few sources beyond computers are outputting these resolutions due to bandwidth limitations
#What is 4k ultra hd video 1080p
This resolution has the same aspect ratio of 1080p HD, or 16:9.Ĥ096x2160, commonly referred to as 4K, is primarily used in the film and broadcast industry and has a native resolution of 4096x2160. Before we get into some design considerations, let's first clarify a few facts.ģ840x2160, commonly referred to as Ultra HD or "UHD," is exactly four times the resolution of 1080p (1920x1080). In today's current state of hardware and cables, there are a few things to understand when designing and deploying these Ultra High Resolution solutions. Some even say "4K ready." Unlike the 3D buzz several years ago, it would appear that 4K is here to stay. Everywhere we turn to lately in the Pro AV space has a "4K" or "UHD" badge stuck to it.
