So, you’re wondering, how is ESPN able to broadcast 3D television from the World Cup? Here’s a look inside the sports cable giant’s 3D Master Control Room. Right now, it’s a humble setting, but as Engadget reports, it’s a highly sophisticated one — and one that figures to grow dramatically in size and scope as more content becomes available and more consumers purchase 3D equipment for the home.

Want to watch the World Cup in 3D? Come by our Denver and Colorado Springs stores during the games or drop by anytime to watch what we have taped so far.

Let’s face it, 3D viewing at home is an exciting prospect, but how do you ever have enough glasses to invite over a raft of people for, say, a Super Bowl party? Toshiba just demo-ed a prototype LCD at the SID 2010 show in Seattle that allows 3D viewing WITHOUT glasses. Right now, the technology isn’t full developed, but as you can read at Electronics House, it’s a step toward a glasses-free 3D viewing experience.

Speaking of 3D, remember you can watch the World Cup in 3D at Listenup’s Denver store. Learn more here.

The World Cup isn’t just the planet’s biggest sporting event: It’s a launching pad for 3D broadcasts. Beginning with Friday’s tournament-opening game between South Africa and Mexico, ESPN will be airing multiple games in 3D.

Don’t have a 3D-enabled TV yet? No fancy 3D glasses? ListenUp has you covered. Chris Havekost, our Denver store manager, wants you to stop by during store hours whenever there’s a 3D game on and take in the action on Panasonic and Samsung 3D-ready TVs. Here’s a complete schedule of 3D game broadcasts (all times are Eastern) to help you plan your visit. (Games also will be taped for replay, so just about any time can work). Call the store (303-778-0780) at 685 S. Pearl St. with any other questions you might have.

Live farther south in Colorado? Our store in Colorado Springs (719-633-2600) is showing World Cup games in 3D on a 65-inch Panasonic Plasma screen.
