Sky Multiscreen is a paid add-on available with a Sky Q TV subscription that enables you to watch your Sky TV content in more than one room. It allows you to watch all channels to which you subscribe in any room you like, and even outside of the house using mobile and tablet devices. With Sky Multiscreen, you can add up to four Mini boxes to your main Sky Q box setup, and each Mini box lets you watch Sky in another room. Sky Go Extra comes included as part of Multiscreen, and you can download shows to watch on your tablet or mobile on up to four devices. The cost of Sky Multiscreen is £15 a month, on top of your Sky Q subscription.
