There’s little to beat the wow factor associated with beaming video straight from a tablet a TV. The good thing about Android is that there’s more than one way to do it. Miracast is a wireless standard that creates an ad-hoc network between two devices, typically your tablet and a set-top box which supports Miracast.
An increasing number of TVs support Miracast without the need for extra hardware. Miracast uses H.264 for video transmission, which means efficient compression and decent, full HD picture quality. Better yet, Miracast supports Digital Rights Management (DRM), which means services such as iPlayer and YouTube can be streamed to a TV. Not all services work, though – see Playing Back Video below. Android devices running Android 4.2 support Miracast.
An alternative is Google’s Chromecast. This inexpensive £30 ‘dongle’ plugs into a spare HDMI port on your TV and connects to your wireless network. Chromecast support is burgeoning, which means content from services such as iPlayer, Netflix, BT Sport and others can be played with the Chromecast dongle doing all the legwork instead of your tablet, and that’s good news for battery life.
As of July 2014, it’s possible to use Chromecast to mirror the display on your Android device, allowing you to hit play on a tablet and have (non DRM-protected) video start playing on your TV. The same goes for anything the screen can display, including apps, games and photos.
