The set-top box is connected between the aerial socket and your television set. Disconnect you current aerial cable from your television set and connect it to the set-top box. Finally, connect the set-top box to your television set.

In the most common set up, the set-top box and your television set should both have SCART sockets (see figure 1), so that you can connect them using a SCART-SCART cable which is suitable for both devices.

If your television set and set-top box both have HDMI sockets (see Figure 2), you should use this connection, for better sound and picture.

If your television set does not have any of these sockets, you can:

• acquire a set-top box with integrated modulation or you can acquire an RF signal modulator and a DTT set-top box;
   
• purchase a new television set with DVB-T and MPEG4/H.264 or one with a SCART or HDMI socket.

DTH set-top boxes are connected in the same way as DTT set-top boxes: connect the cable from the satellite dish satellite to the set-top box and then connect the set-top box to your television set using a SCART or HDMI cable.
