Why does chromecast require an Internet enabled network connection...? Can it work with out internet ?

you're not actually streaming videos from your devices, that's why when you turn off your tablet or lock it when you're watching the video, it does not turn off. think of it as another computer, it just looks up the video and plays it. if you want to stream to your tv from something like your phone or tablet, you would have to use a cable.

for example, when I'm laying down, i use my nexus 10 to stream video via my chromecast. when I want to play a game like gta san andreas on the tv with my moga pro, I use a mini hdmi to hdmi for my tv to play games on it, it's actually really cool. I love the chromecast simply because it does what it's supposed to and it's cheap, it's almost too good
