The N2 doesn't have an infrared transmitter so it won't be possible.

It might be possible if you have Comcast Xfinity, through an app called Zeebox, not sure though.

As Caloy stated, it's a hardware feature. But I think the Logitech Harmony line of products might be able to do what your looking for via BT to IR (or something like that). But it is an expensive piece of equipment.

I remember having a blast changing channels of a TV in a restaurant/bar with my Sony Clies and Axim x51v. It was hilarious (to me).

The Note 8 and Note 10.1 are the only Notes that have built-in IR transmitters.

 

Also if you had Direct TV Genie, which is WiFi it is possible as well. Had a hoot flippin channels from my office while the wife was watching the tube, she couldn't figure out what was going on and why the channels kept changing. She was ready to call and complain that something was wrong with the new setup.

 

I'm able to change channels, set DVR using the Comcast Xfinity app which is perfect for me.
