Why choose someone you never meet and what you can watch on TV and when? True, there is always a choice option, but the selection is still quite limited and you can only track them when they are broadcast, unless you save the programs in advance. Wouldn't it be better if watching TV was something like browsing the Web, so you could choose the program you wanted to watch and where did you feel like watching it? This is one of the promises of IPTV (Internet Protocol Television), which uses Internet technology to "optionally" offer TV programs. How does it work? What benefits will it bring to us? What will be the challenges that broadcasters and telephone companies will face to offer these new services? Let's have a closer look!

What is IPTV?
From a TV observer's point of view, IPTV is very simple: instead of receiving TV programs with broadcast signals from your home to a roof antenna, satellite dish, or fiber optic cable, you get them streamed (downloaded and played at the same time) via your Internet connection. Probably only 1-10 Mbps (million bits per second / roughly the amount of information in an average novel that goes one second every day on your computer!) Not a type of connection you can process, but a broadband line about 10 times wider Maybe 10-100Mbps bandwidth ( information carrying capacity. You can watch the program on your computer or in a set-top box (some kind of adapter that fits between your internet connection and your existing television receiver can display the Internet programs by analyzing the incoming signals).
IPTV in terms of a publisher or telephone company is a bit more complicated. For all the videos you want to use, you need an advanced storage system and a web-style interface that allows people to choose the programs they want. After a viewer selects a program, it encodes the video file in a format suitable for streaming, encrypting it (so that only the paid person can decode and encrypt it), placing the ads (especially the Program is free), and thousands (or millions) from a person on the Internet let the person flow something at every moment. You'll also need to find out how to do this to ensure a consistently high-quality image (especially what your paying advertisers can certainly expect if you're advertising with your program).
Three types of IPTV
IPTV is offered in three different flavors. The first kind and possibly the video you already use is called an optional video (VOD). With a service like Netflix (an online movie site), you can watch a wide range, pay your money and choose a TV show or movie you want to watch from there. A different type of IPTV is offered by some of the world's more enterprising TV broadcasters. In the UK, the BBC (British Broadcasting Corporation) makes its programs online last week using a web-based video player called BBC iPlayer. Such services are sometimes referred to as time-shifted IPTV, because you are watching ordinary, planned publications at a convenient time for you. The third type of IPTV requires the broadcasting of live TV programs being viewed on the Internet; hence live IPTV or IP simulation broadcasts. All three forms of IPTV can work with your computer and an ordinary web browser or a set top box (for better quality) and a normal digital TV. All three can be delivered over the Internet or a managed private network that works basically the same way (for example, from your phone and Internet service provider to your home through your provider's network).

Personalized Interactive TV
Traditional TV broadcasting means one-way, multiple transmission of information, but combining television and video images with the Internet offers the opportunity to provide a much more interactive experience where information flows in both directions. So far we've been used to TV talent shows where people talk to people to play their favorite games, but we can expect more participation in the programs we're watching, where in the future TV programs are broadcast online. Instead of talking to a live audience of a few hundred people in a studio,
