Video has to be tailored to fit within the transmission capacity 
available. The resolution of analogue black and white TV was designed 
for the spectrum available. When color was added, its resolution was set 
even lower to fit it in. Digital TV has similar compromises with 
compression.

UHD has to be compressed for transmission.
