.. to include streaming of recorded content from the Q, but you would not be able to view live TV.
So the preview could function easily as a monitor device that would control the quality and quantity of the shows your child can watch. They would be limited to watching predetermined television shows and/or movies rather than scan through the channels.
I had friends who made their children keep the TV in the closet. They were allowed to take it out to watch certain shows, but they had to dismantle the TV and put it back in the closet when the show was done. It wasn't adult content that they worried about, it was the habit of just idly flicking through the channels to kill time.
They now have three beautiful, very articulate and athletic daughters.
This seems like a valuable option that is worth promoting.
