An IPTV makes use of the internet to receive the content at home. Generally, this is done by attaching a set top box with the television. The set top box provides the link between internet signals received and converts these signals into a format which can be read by TV. Now, these boxes, also called the STBs in short, are connected to the smart TV through HDMI cables or using wireless connection. So, basically the set top box works as a translator.
