The biggest challenge of broadcasting is to be able to deliver high quality video content (UHD 4K and 8K) from point A to point B, anywhere in the world and on all connected devices (television, smartphone, tablet ). According to the Futuresource Consulting’s study, the proportion of 4K TVs will represent 35% of television purchases worldwide thanks to lower prices and the desire of users to have bigger screens.
What is UHD?
UHD is a combination of several parameters:
-
HDR, or high dynamic range television restores real colors. Contrasts and luminous intensity are increased for a closer perception of how our eyes see in reality Wide Color Gamut (WCG) manages the color space and provides a better color display.
-
Next Generation Audio, like Dolby Atmos, guarantees the best sound quality.
-
High Frame Rate (HFR) increases the number of frames per second (60 frame/s) and thus improves the viewing experience, especially in 3D.
These technologies reproduce better textures, transparency and file quality. 4K, meanwhile allows to keep an optimal quality regardless of the size of the screen.
But like all good things, the use of UHD 4K brings many challenges:
-
4K UHD files have more pixels and are, therefore, much larger. It is necessary to compress those files to be able to deliver and share them. To do so, H265 / HEVC compression allows to divide the file size by 2 without degrading the rendering.
-
You also need the space to store the content, which leads to issues concerning storage solutions like the Cloud.
-
4K video is the most hacked content for downloading and streaming. Therefore, additional precautions must be taken to ensure safe exchange and broadcast (DRM, Watermarking).
-
Hardware questions must also be considered. Even though 4k is growing more and more, it is not yet compatible with all screens and competing TV standards.
