IPTV is the term used to describe the internet streaming of TV programs over broadband Internet instead of the more traditional cable or satellite service. The new TV content is streamed directly to a single set-top unit. In essence, it’s the digital transmission of television programs and other media over IP networks. The term “iplexer” simply means an IPTV subscriber. They can stream IPTV via a computer satellite TV connection or using special IPTV devices.
