What Is IPTV And How Does It Work???
With Netflix and the Internet, TV has become outdated. Why have to watch shows only when they are broadcast? Wouldn't it be better to watch TV as if you were browsing the web, so you can choose the show you want to watch when and where you want it? This is one of the promises of Internet Protocol Television (IPTV), which uses Internet technology to broadcast TV programs "on demand". Let's see what it is!
What is IPTV?
IPTV is growing rapidly, with the emergence of new providers and new services alongside traditional TV providers, which offers to increase IPTV offerings.
IPTV stands for "Internet Protocol Television". The “IP” of IPTV is the same as that of your IP or VoIP (voice over IP) address. This means is that television programming is transmitted using the Internet Protocol.
With cable or satellite television, broadcasters send signals and viewers receive them. You can only watch what is being broadcast. Unless you have a recording device, you can't just choose from the programs broadcast by the different channels and watch what's available.
IPTV is different. Instead of transmitting content by pulses of light over a fiber-optic cable or radio waves from a satellite, IPTV sends shows and movies over a broadband Internet connection.
Instead of showing a series of shows on a specific schedule, most IPTV channels use video on demand (V0D) or time-lapse media.
There is a complicated network architecture behind it all which makes it functional, including a lot of transcoding from traditional signals to IP signals. But the important thing is that you don't have to watch what's on the air. You can tell your provider what you want to watch and they'll send it to you immediately.
If you've used a streaming service like Netflix, it's the same idea, but with TV instead of movies or series.And We recommended The Best Site For IPTV IPTVSpacex.com
Reception of IPTV
All three forms of IPTV can work either using your computer and a regular web browser or (for much better quality) a set-top box and regular digital TV. All three of these services can be offered either over the public Internet or through a managed private network that operates essentially the same (for example, from your telephone and Internet service provider to your home, entirely through the provider's network). .
Do you need a decoder for IPTV?
Your computer, on the other hand, does not need anything to watch IPTV. Once signed up for a service, you can use it to watch whatever you want in any of the IPTV formats. So if you can mirror your screen to your TV, you can watch IP TV without a set-top box.
Since most televisions are not equipped for IPTV, you may need a set-top box that "translates" what you receive over your Internet connection into a format that your television can play. The future of IPTV probably involves purchasing set-top boxes that receive input from your Internet connection (via Ethernet cable or Wi-Fi), decode the signal, and display a picture on your large-screen high-definition TV. Set-top boxes are in fact stand-alone computers programmed to do only one chosen thing: receive video packets continuously, decrypt them, convert them to video files (MPEG2, MPEG4, or whatever format), and then stream them. display as high quality TV pictures. Apple TV works this way, using a set-top box to perform simple applications on a lightweight operating system (tvOS), which handles the process of streaming video over the Internet.
As a simple, more compact, and much more discreet alternative to a set-top box, you can use what is called a dongle, which looks a bit like a USB flash drive, but allows secure access to Internet TV programs. The dongle plugs into an HDMI price on your TV and connects via Wi-Fi to the Internet to directly stream TV programs, movies and music.
Google's Chromecast is a little different :, you launch it with your computer, tablet or smartphone (which effectively becomes a remote control), after which it streams your movie or TV program directly from the Internet.
IPTV exists in three different versions
Video on demand (VOD)
VOD streaming is exactly what it sounds like; you receive video whenever you request it. Movie streaming sites are providers of VOD. There is no time limit on what you can watch (other than what the service is currently licensed for).
You tell the service what you want to watch, they send it to you over the Internet and you watch it. Simple.
With a service like Netflix or Amazon Prime video, you select a TV show or movie that you want to watch from a wide range. They work in the form of a subscription, there are also services where you pay per content consumed
If you've watched “catch-up TV,” you're familiar with this type of IPTV. Many broadcast networks now allow users to watch shows that they missed while on air.
The important difference between delayed broadcast media and video on demand is that shared content has a limited shelf life. You can't go back and watch an episode of a show that you missed years ago.
You watch regular and scheduled shows at a time that suits you.
Video on demand and delayed media are very similar. The main difference is the length of time you can watch a program after it has aired.
The third type of IPTV is to broadcast live TV broadcasts over the Internet while watched, that is, live on IPTV or simulcast over IP. So as with TV broadcasting, you can also watch live broadcasts on IPTV. Many people watch sporting events this way; It's easy to watch a game stream on your phone when you're on the go.

Sport appears to be the area of television that has been adopted the most quickly by IPTV. There are many sports subscription packages (beIN or Eleven Sport for Belgium) that you can watch from your computer or stream on your TV whenever you want.
Live IP TV looks like regular TV to the consumer.
TV becomes multidirectional media with IPTVSpacex
Traditional television broadcasting means broadcasting information in one direction only. Now, the combination of television and videos with the Internet opens up the possibility of a much more interactive experience where information flows both ways.
We can expect much more participation in the shows we watch.
Instead of speaking live to an audience of a few hundred people in a studio, TV stations will reach an audience of millions of viewers who can send comments instantly. We can ask questions and have the witness answer them a few minutes later, we will vote on how we want the TV series to play out, with multiple endings filmed in advance and different endings shown to viewers. different !
Targeted advertising on your TV
If you've used video-on-demand services, you may have noticed that some of them are already showing interactive advertising: since you are only watching a video on a regular web page, you may click on a video. ad to go to a website and find out more.
With the trend towards highly targeted behavioral advertising online, advertisers will use IPTV to serve ads that are much more relevant to the people who watch them. This will prove to be more effective and more appealing to them than the catch-all ads they are showing today on current TV channels. It is very likely that you will even be able to choose which ads you want to watch by setting your settings as on Facebook.
How does IPTV work?
With conventional television, broadcasts are broadcast by being turned into radio waves and broadcast through the air to an antenna on the roof of your home. The antenna converts the waves into electrical signals and your TV decodes them to produce sound and picture (satellite TV works the same, except that the signal bounces back and forth in space, while satellite TV cable sends signal directly into your home without radio waves). How is IPTV different?
Technical constraints for the broadcaster
From a broadcaster or telephone company perspective, IPTV is a bit more complex. You need a sophisticated storage system for all the videos you want to make available and a web interface that allows people to select the programs they want. Once a teleview
ator has selected a program, you must be able to:
encode the video file in a format suitable for streaming,
encrypt it (by encoding it so that only people who have paid can decode and receive it), integrate advertisements (especially if the program is free),
to distribute it on the Internet at any time, from one person to (potentially) thousands or millions of people at a time,
find a way to deliver a consistently high-quality image (especially if you're running ads with your programming - because that's what your paid advertisers will certainly expect).
Live shows are streamed as they are produced, but pre-recorded shows and movies must be stored so that they can be selected and played on demand. Some V0D services limit the number of programs they offer not because they lack storage space, but because it is a way of limiting their service's overall bandwidth and its impact on the Internet.

Preparation of programs
First, the TV program must be converted into a digital format that can be delivered in packets using Internet Protocol. Sometimes the original program will already be in digital format; sometimes it will come in the form of a standard analog television picture that requires a little more processing to turn it into a digital format.
With current bandwidth limitations, videos must also be compressed so that they can be streamed without being buffered (periodic delays caused by the accumulation of incoming packets by the receiver). In practice, this means that the programs are encoded in MPEG2 or MPEG4 format. Once this is done, the announcements should be inserted and the information should be encrypted.
When you browse a website, you are actually creating a temporary link between two computers so that one can "suck" information from the other. Your computer, the client, pulls information from the other, usually much more powerful computer, the server, by connecting directly to an IP address that corresponds to the website you want to visit.
The client and the server have a brief, intermittent conversation in which the client asks the server for all the files it needs to build the page you are viewing. The servers are generally so fast and powerful that many clients can download this way simultaneously with very little delay. This ordinary type of download between a client server and a server is known as IP unicasting.
However, when it comes to streaming, clients are putting a much greater (and concurrent) load on the server, which can cause unacceptable delays and buffers. So with streaming another type of download is used, known as IP multicast, in which each packet leaves the server only once but is sent simultaneously to many different destinations; in theory, this means that a server can send information to multiple clients as easily as to a single client.
IPTVSPAFCEX to save bandwidth
Many TV providers are now taking a hybrid approach to IPTV to solve some of the problems associated with fully IP broadcasts. IPTV requires a lot of bandwidth to transmit so much data at high speed.
IPTVSPACEX combines traditional television services with IP-based ones. The biggest selling point is that everything comes in one box. This allows television providers to broaden their offering to their subscribers. It also facilitates the deployment of new products and services without a complete decoder overhaul. This is a good way to go from a traditional model to a more modern model.

Barriers to IPTV
The broadcasting of IPTV seems easier to implement than it can be in practice. The biggest hurdle right now is that too few homes have broadband connections of enough capacity to handle a single high-quality TV stream, let alone multiple streams simultaneously.
Upgrading ordinary broadband connections to broadband fiber optic, so that they consistently deliver 10-100 Mbps speeds to homes, will take time and require significant investment. Until then, IPTV providers will not be able to guarantee a "quality of service" as good as television broadcast by cable, satellite or over the air.
Latency and packet loss are already issues for VoIP phones and they become much more of a problem when broadcast quality video is added into the stream. As IPTV uses compressed video formats such as MPEG2 and MPEG4, packet loss has a much more severe effect than uncompressed video or audio streams: the higher the compression rate, the greater the effect of each packet. lost in the picture you see is important.
The future of IPTV
There is no doubt that IPTV will gain popularity. Increased user demand as well as improved networks will support this growth. Television will increasingly move away from broadly defined channels and rigid schedules and towards more focused, pay-per-view and pay-per-view programming.
IPTV could take off in exactly the same way broadband Internet did in the early 2000s: Back then, as people used the Internet, they felt constrained by the limits of dial-up connectivity, demanded a high higher quality throughput.
Major media providers plan to offer new streaming services to compete with Netflix, Amazon Prime and other streaming heavyweights. And more traditional TV providers allow time-lapse media through their apps. Even cable companies allow their subscribers to watch from their phones.
And now that people can create their own channels to easily distribute their content, the number and variety of IPTV options will increase rapidly. Viewers will no longer be limited to what broadcasters share; they'll be able to walk towards each other to see everything from fitness videos to movies aimed at special audiences.
Another side of it is that there are many services emerging that allow users to create their own video on demand and live streaming services. This way people can share their skills, advice, and passions with anyone else in the world.
