<p>Now you can do a lot more with a second screen than post snarky comments on Twitter. Tech and media companies are rolling out apps and gadgets that let you send video wirelessly from a phone or tablet to your HDTV, get more information about the show you are watching and use your device as a remote control.</p><p>Mobile devices make convenient video players. But to get the thrill that only a big screen can provide, try Apple's AirPlay Mirroring app. With it you can wirelessly sling whatever is showing on your Apple phone, tablet or PC to an HDTV - as long as you also have an Apple TV media-streaming box ($99). AirPlay Mirroring can transmit everything that's on your mobile device, so it's handy for slide shows and other shared activities.</p><p>A free Google YouTube app does a similar trick for Android users.
