We should add that the High Dynamic Range (HDR) standard being used by the BBC is known as Hybrid Log-Gamma (HLG), which the BBC says “ provides improved picture quality not only to HDR Ultra HD devices, but to the vast majority of Standard Dynamic Range Ultra HD devices, too.”
All footage will be shown at 50fps (frames per second). At present the BBC iPlayer service recommends a download speed of just 2.8Mbps (Megabits per second) for their normal HD video streams, which falls to 1.5Mbps for “ standard quality” (SD).īy comparison the BBC are now recommending “ at least” a 40Mbps connection to view the best full 4K quality (3840 x 2160 pixels) and if your connection can only deliver 20Mbps+ then you’ll instead be presented with a lower resolution of 2560 pixels (wide), which is still well above full 1080p HD quality (1920 x 1080 pixels) but it’s obviously not 4K. Assuming you actually manage to get on to one of these trial screenings then you’ll also require a better than “ superfast broadband” (24Mbps+) connection to get the most out of it, as well as a 4K and HDR supporting TV.
