IPTV makes it possible to have hidden contact with each user by means of a return channel of connection. The presence of the return channel of connection is a key parameter in the IPTV System. The connection with the end user is carried out through the receiver-decoder (Set-top-Box), established on the party of the user. The small size receiver-decoder saves space, and there is no need for extra furniture for the additional TV equipment.
Using the IPTV system, you can study consumer tastes and needs, and collect statistical data by using the ratings of telechannels, programs and films.
