What Is IPTV? Everything You Need to Know About the Future of Video
If you’re not a part of the media landscape, there’s a good chance you haven’t heard of IPTV. But you’ve probably been using it for years.
And it’s likely that you’re going to be using it more in the future. IPTV is growing quickly, with new providers and services popping up alongside traditional TV providers with more IPTV offerings.
But what is IPTV? What does IPTV stand for? How does it work? And how can you use it to improve your TV-watching experience?
We have the answers.

What Is IPTV?
Let’s start with the basics. What, exactly, is IPTV?
IPTV stands for “internet protocol television.” The “IP” in IPTV is the same as the one in your IP address or VoIP (voice over IP). All that means is television programming is being communicated using the internet protocol.
To understand what that means, you need to know a bit about how non-IPTV works. With cable or satellite TV, broadcasters send out signals and viewers receive them—you’re only able to watch what’s being broadcasted. Unless you have some sort of recording device, you don’t get to dictate what’s on when. You just tune in when you can and watch what’s available.
IPTV is different. Instead of transmitting content via light pulses in fiber-optic cable or radio waves from a satellite, IPTV sends shows and movies through your standard internet connection. (You may be using a cable or satellite internet connection, but these are independent of the ones that usually carry your TV signals.)
Instead of broadcasting a range of shows on a specific schedule, most IPTV uses video on demand (VOD) or time-shifted media—we’ll discuss these, and a third format, in just a moment.
There’s some complicated network architecture behind all of this making it work, including lots of transcoding from traditional signals to IP-friendly ones. But the important thing is that you don’t have to watch what’s being broadcast. 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 or Hulu, it’s the same idea, but with TV instead of movies or syndicated shows.
Do You Need a Set-Top Box for IPTV?
Because most TVs aren’t equipped for IPTV, you may need a set-top box that “translates” what you receive over your internet connection into a format that your TV can read.
Your computer, on the other hand, doesn’t need anything to watch IPTV. Once you sign up for a service, you can use it to stream whatever you want in any of the IPTV formats (which we’ll discuss next).
So if you can mirror your screen to your TV, you can watch IPTV without a set-top box.
Many TV providers are now adopting a hybrid approach to IPTV to solve some of the issues with fully IP-enabled broadcasts. IPTV requires a great deal of bandwidth to transmit a ton of data at high speed.
Hybrid IPTV combines traditional TV services with IP-based ones. The biggest selling point is that it’s all delivered through a single box. This lets TV providers expand their offerings to their subscribers.
It also makes it easier to roll out new products and services without completely overhauling the set-top box. It’s a good way to transition from a traditional model to a more modern one.
How Does IPTV Work?
There are three different IPTV formats. We’ll take a look at each one individually.
Video on Demand (VOD)
VOD streaming is exactly what it sounds like; you get video whenever you demand it. Movie-streaming sites are VOD providers. There’s no time limit on what you can watch (other than what the service currently has the rights for).
You tell the service what you want to watch, they send it to you via the internet, and you watch it. Simple
Netflix, Hulu, and Amazon Prime Video are popular examples of VOD services. (There are many smaller, niche services available, as well.)
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 when they have the time to do it.
The important difference between time-shifted media and VOD is that the content being shared has a limited shelf life. You can’t go back and watch an episode of a show that you missed several years ago (well, you could, but it would be VOD then).
One of the most popular services that offers time-shifted media is BBC’s iPlayer.
(If you think that VOD and time-shifted media sound very similar, you’re right. It mostly has to do with how long you’re able to watch a show after it airs.)
Like broadcast TV, you can also watch shows live on IPTV. Many people watch sporting events this way; it’s easy to stream a game on your phone while you’re on the go.
Other than being broadcast over the internet instead of through traditional TV media, live IPTV is pretty much the same as regular TV.
FOX Sports Go, CBS Sports HQ, Hulu Live TV, and Sling TV all offer live IPTV.
The Future of IPTV
It’s difficult to tell how many people are using IPTV services at the moment. With the wide variety of providers, different formats, and a huge amount of pirated content available, there are a lot of things to keep track of.
But there’s no doubt that IPTV will be increasing in popularity. Grand View Research estimates that the market will be worth over $117 billion by 2025. The increase in user demand as well as improvements in networks will support this growth.
Grand View also predicts that subscription-based IPTV will grow quickly over the next decade, suggesting that services like TVPlayer and Hulu Live TV will gain in popularity.
Some of that growth has started already.
Major media providers are planning to offer new streaming services to compete with Netflix, Amazon Prime, and other streaming heavyweights. And more traditional TV providers are allowing for time-shifted media via their apps. Even cable providers are allowing their subscribers to watch from their phones.
And now that people can create their own channels to distribute their content with ease, the amount and variety of IPTV options will be increasing quickly. Viewers won’t be limited to what broadcasters are sharing anymore; they’ll be able to go to each other to see everything from fitness videos to audience-specific movies.
In short, the future of TV is IPTV.
