The defenition of second screening is when you would use a tablet/ phone along side the use of the television. This is used for engaging people in the occassion of event TV. This is when people tune in to a program when it is broadcasted, this second screening feature would not be available if you do not tune in to the program of film when it is being broadcasted.
Another way in which second screening can be used is along side the consoles for gaming. This is a feature that is being used with consoles such as the wiiU but will be used a lot in future gaming.
The main advantage of this would be that it makes interactivity among medias and may be a way of stopping piracy
