Windows Media Player and Windows Media Center will not play 3D Blu-ray movies in Windows 8. If your computer did not come with 3D Blu-ray player software, you may need to install third-party software to play 3D Blu-ray movies.
Best Answer: That's called an F-Type Barrel. See the link below. It's used on your wall jack for connecting the internal house wiring on the back side, and for you to connect a patch cable to your TV set's antenna jack on the front side. You could also use it to connect 2 patch cables together to make an extension.
With cable and satellite TV bills steadily climbing, it's no surprise that cord-cutting is the most-mentioned reason for connecting your TV to an antenna to get free over-the-air reception.
