What is IPTV?
IPTV (Internet Protocol Television) is the new way to watch Internet TV channels. Very simple to explain: instead of using an antenna, a satellite or fiber optic cables to receive the signals and therefore the traditional channels to be seen, these same channels, whether digital terrestrial or satellite, are transmitted almost simultaneously in streaming with a live stream or on demand, all through some protocols different from those we are used to seeing on the web.
In a nutshell, it is a method by which television signals are transmitted through the Internet, in a system technologically different from WebTV and more oriented to the use of live content. To take advantage of this service, you just need to have any smartphone, tablet, Mini PC, PC or smart TV connected to an internet network and there are many free channels that you can watch in comfort via IPTV.
But now let’s take a good look at how IPTV works.
How IPTV works
In normal television the signal is sent via radio waves to your antenna or from the satellite to the dish. The same antenna / dish then converts the received signal into an electrical signal and conveys it to the decoder (integrated into the TV or external) which decodes it into sounds and images.
IPTV, on the other hand, provides for the transmission of television channels via the internet and can have two types of programs: live ones, which are broadcast while they are being recorded, and pre-recorded ones, which need to be deposited on a web space to then be reproduced by the On Demand user.
The correct functioning of IPTV rests on two fundamental bases.
First the gang. To better understand what bandwidth is, we need to think of the internet as a series of highways and data as a series of cars running through them. If the bandwidth of a site is low, then some information is lost and not all are able to reach the recipient in a short time; the transmission, therefore, will suffer some interruptions, just as if there was a lot of traffic on these highways. On the contrary, if the bandwidth is large, then the information will be able to travel in a short time and in an orderly way, without losing data packets.
The second fundamental thing is audio and video streaming. Streaming, in fact, makes it possible to see the contents by downloading them directly to our device in the form of temporary files which will then be deleted, both live and On Demand.
To simplify everything, summarize and explain in a simpler way IPTV what it is: in a nutshell, it is a television that no longer arrives in homes via antenna, satellite dish or cable, but offered in streaming, and therefore through the network. Home internet (or you can use that of your smartphone or a more secure VPN ).
Multicast protocols (usually the IGMP protocol) are used for live contents, which are therefore used by many users at the same time, while unicast protocols are used for on-demand contents which are therefore sent to a single user.
How and where can I see IPTV channels
To watch IPTV, as mentioned above, you first need an adequate internet connection, as the bandwidth used can be considerable. Furthermore you need a device on which to play audiovisual content, therefore any smartphone, tablet, PC, TV (but with the addition of an external device which we will talk about shortly) or smart TV.
As happens in television with satellite or digital terrestrial, in order to view IPTV channels, a program for the use of IPTV is then necessary that functions as a decoder which is provided with an address from which it must receive the transmitted data.
Some widely used software are Kodi , which we talked about in this blog, VLC or windows media player, CherryPlayer, Net TV, Perfect Player and many others. The programs alone, however, do not automatically allow the use of the channels: you need an IPTV list. The lists are in M3U format and can be used in many Android and IOS applications.
Of course we mention our Anroid Application and Windows PC with integrated VPN
it only needs the credentials to work (user and password) provided by us.
