The science behind green screens

Future Tech 'St. Patick's Day' Edition: Featuring a pot of bitcoin & Irish tech for connected cars.

Celebrate all the green you’ll be seeing this St. Patrick’s Day with a little tech trivia. Take a look at how those clever green screens work on news programs and TV shows. Explore how Kodak may help you find your own pot of gold…or rather, a pot of cryptocurrency. Then read about the Dublin startup that is helping make sure that new Irish cars are connected to LTE networks right off the assembly line.

How green screens actually work

From Popular Science:

For those unfamiliar, a green screen is a tool used in film and television production that allows editors to erase and replace the colour of said screen. This is accomplished through a tool called a “chroma key.” Essentially, setting a chroma key tells the computer to ignore a certain color in a picture or video. Once that color is gone, a new image or video can be placed underneath the original, filling the now-transparent area.

Here’s an example of how a green screen and chroma keying look on-air from “Whose Line Is It Anyway?”:

Chroma keying can also be used strategically to eliminate parts of bodies or entire people, which is why you may see people wearing polyester/spandex suits that are all one color — better known as “chroma key suits” or “morph suits” — in behind-the-scenes clips of your favorite movies and TV shows.

But every now and then, you’ll see someone accidentally wear the same color as the screen that’s being taken out. And when that happens, it’s usually pretty funny.

Will KashMiner lead you to a pot of Bitcoin at the end of the rainbow?

From CNBC:

Kodak’s stock more than tripled in a week since the once-giant of photography announced a pivot into blockchain technology and cryptocurrency.

Part of their move is a Kodak-branded mining rig called the KashMiner, which was showcased at this year’s CES. It’s created and run by a company called Spotlite and has licensed the Kodak name.

Here’s how it works: Users pay $3,400 to rent the mining machine for two years. Kodak claims the KashMiner will produce about $375 worth of new bitcoins every month, which would lead to estimated revenues roughly $9,000 over those two years.

But here’s the catch: You have to give back half your profits.

Dublin startup gets cars connected to any high-speed mobile network

From Irish Tech News:

The next generation of cars and trucks are getting a lot more connected thanks in part to a Dublin startup.

Cubic Telecom, a company that creates software for connecting cars to LTE mobile networks, now has software in more than a million cars as they roll off the line. The privately-held startup announced the major milestone at the Mobile World Congress in Barcelona Monday.

The software, installed in new vehicles, enables the cars’ systems to log into any high-speed mobile network. The company began rolling out the software 15 months ago. Today, those Cubic-enabled smart cars are in 35 countries and on 40 different mobile networks.
