Different between outdoor antena TV ,Cable TV, DTH TV

In Our Country Nepal we are watching Cable TV .outdoor antena TV ,Cable TV, DTH TV[Direct broadcast satellite (DBS) )], IPTV (Internet Protocol Television) , etc.Origin of TV in Nepal From the time when TV came into existence, there were different types of Antennas too that helped people view the channels. The traditional Yogi Uda Antenna was used. It was quite difficult at those times because we cannot rely upon the signal of the transmission. In times of rain, and wind we have to keep adjusting the antennas and there are chances that the antenna changes direction even when a crow sits on it. And there were only a very few channels. And when lightning strucks the first thing to be done is to remove the antenna connection.

Direct broadcast satellite (DBS) is a term used to refer to satellite television broadcasts intended for home reception, also referred to more broadly as direct-to-home signals. The expression direct-to-home or DTH was, initially, meant to distinguish the transmissions directly intended for home viewers from cable television distribution services that sometimes carried on the same satellite. The term predates DBS satellites and is often used in reference to services carried by lower power satellites which required larger dishes (1.7m diameter or greater) for reception.

IPTV (Internet Protocol Television) is a system where a digital television service is delivered using Internet Protocol over a network infrastructure, which may include delivery by a broadband connection. A general definition of IPTV is television content that, instead of being delivered through traditional broadcast and cable formats, is received by the viewer through the technologies used for computer networks. For residential users, IPTV is often provided in conjunction with Video on Demand and may be bundled with Internet services such as Web access and VoIP.
