This means that the TV material is packetized to IP packets and delivered by means of a high speed accessibility system (like Digital Subscriber Line (DSL)).
The saying IPTV should not be mistaken with the shipping of TV on internet (for example viewing YouTube films or live channels like NDTV on your PC in your broadband connection). Traditionally internet is still a best effort program and does not offer any warranties for one service. On the other hand, the IP platform employed for shipping of IPTV is built specially to supply this service and consequently has performance and security features required to build a reliable service which customers will pay for.
Therefore, IPTV is normally supplied by fixed system Providers who already offer voice and internet services to the last period (i.e., the customer premises), and also have control within the neighborhood by the head end prior to the customer premise. Traditional TV using satellite or cable only includes Live TV and possibly a predetermined little assortment of images which might be regarded as pay per view. IPTV is typically wealthier with features like gaming, time shift tv and Video on Demand (VoD), apart from live TV. More on these characteristics are described in the FAQ.
