IPTV Overview– Part 1

IPTV with its long name Internet Protocol Television is a television system that this service is delivered using the IP suite over a packet-switched network like internet. Traditionally, the television system is delivered through terrestrial , cable tv or satellite. But IPTV is different than these traditional techniques. IPTV looks like the same with Internet TV. There is also Internet TV as you know. But there are many differencies between IPTV and Internet TV. Do not confuse! IPTV has a good QoS and delivered over a managed network. We can give Vitgin TV and BT Vision as an example for the IPTV service. Beside, Internet TV has no guaranteed QoS and usually delivered on unmanaged network/open internet. Youtube is a good example for Internet TV. We can classify IPTV services into three groups.These are: – Live television : Watching at the same time with the world. – Time-shifted television : Recording and watching television whenever you want. – Video on Demand(VoD) : Watching recorded videos , not television.
