Calculate the bandwidth necessary for transmitting in real$-$time HDTV high$-$definition video at a resolution of $1920$ x $1080,25$ bits$/$pixel$,25$ frames$/$s$.$ Assume that no data compression is done.

$($G$=10^9)$

Ans: The bandwidth is Blank $1$Gbps $($round your answer to X$.$X digits, e$.$g$.,2\mathrm{.}3).$
