The only thing I'd add to this is that it displays a webpage that can be controlled from the originating device (and possibly other devices, though I'm not sure if that's baked into the API or if you are on your own as far as getting other device involved). Using your phone or computer as a "remote" is one example of what you can do with these apis. It also has sufficient hardware video decoding capabilities to play back 1080p video streamed over the network.
