IPTV is the delivery of television content using internet over Internet Protocol networks. This is in contrast to delivery through traditional terrestrial or satellite and cable television formats. IPTV offers downloaded media the power to stream the source media continuously. As a result a client media player can begin playing the content (such as a TV channel) soon. This is known as streaming media. Although IPTV uses the web protocol it's not limited to television streamed from the web (Internet television). It is widely deployed in many subscriber based telecommunications networks with usually  high speed access channels into various end user premises with the help of set top boxes or other customer equipment. IPTV is additionally used for media delivery around corporate and personal networks. IPTV within the telecommunications arena is notable for its ongoing standardization process. IPTV services could also be classified into live television and live media, with or without ...

History of IPTV:

Up the first 1990s, it had been not thought possible that a television program might be squeezed into the limited telecommunication bandwidth of a copper telephone cable to supply a video-on-demand television service of acceptable quality as the required bandwidth of a digital television signal was around 200 Mbps which was 2,000 times greater than the bandwidth of a speech signal over a copper telephone wire. DCT may be a lossy compression technique that was first proposed by Nasir Ahmed in 1972, and was later adapted into a motion-compensated DCT algorithm for video coding standards such as the H.26x formats from 1988 onwards and therefore the MPEG formats from 1991 onwards. Motion-compensated DCT video compression significantly reduced the quantity of bandwidth required for a television signal, while at an equivalent time ADSL increased the bandwidth of knowledge that would be sent over a copper telephone wire. ADSL increased the bandwidth of a telephone line from around 100 kbps to...
