Internet television allows viewers to choose the show or the TV channel they want to watch from a library of shows or from a channel directory, The 2 forms of viewing Internet television are streaming and downloading onto a computer. The video may be broadcast with a peer-to-peer network, which doesn't rely on a single website's streaming.It differs from IPTV in that IPTV offerings, while also based on the IP protocol stacks, are typically offered on discrete service provider networks, highly managed to provide guaranteed quality of service and good bandwidth, and usually requiring a special IPTV set-top-box. However, some definitions of IPTV such as that defined by the ITU and the DVB, use the term IPTV as a superset of both 'managed' IPTV and Internet TV.
