Most folks are familiar with Closed Captioning (CC)—the system for displaying text during a TV or video to help those with hearing disabilities follow along. But the system isn’t useful solely to them—if you’d like to watch a movie or TV show silently, for instance. Luckily, there’s lots of CC-enabled content available from the iTunes Store, and enabling the service on Apple’s devices is fairly simple. In iTunes on a Mac or PC, open up the Preferences, select Playback, and turn on the “Show closed captioning when available” option. On an iPad, iPhone, or iPod touch, open the Settings app, tap on Video, and turn Closed Captioning on. Last but not least, you can access the same option on the Apple TV by visiting the Settings menu, selecting Audio & Video, and then turning Closed Captioning on. Now you can enjoy your content—and some peace and quiet. [via OS X Daily]
