Real-Life Math
The editors at your TV station want to create a splashy opening
sequence for a new TV program. While the credits are rolling, they want to
flash a sequence of images across the screen.
They want to create the
idea of movement and fast-paced fun. However, they also want to be careful
that they don't harm viewers by flashing the images too quickly. Some
reports say that rapidly flashing images can cause seizures.
"Math
skills are necessary, but you don't have to be a wizard, as there are many
tools online and in the industry to help you," says Peter Gillespie, who works
for a broadcast engineering association.
"Most of the
'math' done these days is in figuring out a particular bit rate, or storage
capacity, or IOPS [Input/Output Operations Per Second], or the bandwidth of
media."
The editors want you to create images that flash up on the
screen 15 times per second. If you are running the piece for 3 seconds, how
many images will flash across the screen?
How many images per second
would flash on the screen if you reduced the number of images by 20 percent?
