UHD provides 4 to 16 times crisper screen quality than HD
4K UHD has 4 times more, while 8K UHD has 16 times more pixels than conventional HD
(4K and 8K indicate the number of pixels in a horizontal scanning line of a TV screen)
With the HEVC compression method, the transmission speed required is about 16 to 128Mpbs
4K needs 16 to 32Mbps while 8K needs 64-128Mpbs
A digital TV screen has numerous dots (pixels). It ‘draws’ a frame as one would paint on a canvas dot by dot.
So if the screen resolution increases, the screen quality gets better, thus requiring higher transmission speed.
