You came home tired and tired of work. You want to sit down and watch some TV and relax. But you couldn’t find a program to watch. Although you can select, navigate through channels, you can watch very limited and unless you record programs in advance, you can only watch what you capture during the broadcast. Wouldn’t it be better if there was something like watching TV or browsing the Web, so you could choose the program you want to watch. This is one of the promises of IPTV (Internet Protocol Television), which uses Internet technology to deliver bağlı on demand ”TV programs. How does this system work? What benefits does it bring us? What are the challenges for broadcasters and telephone companies to offer these new services? Let’s take a closer look!
From a TV observer’s point of view, IPTV actually works in a very simple way. Instead of receiving TV programs with broadcast signals that come with a roof antenna, satellite dish or fiber optic cable to your home, you can stream them through an internet connection (such as videos that you download and play at almost the same time). Your internet connection speed up to 10 Mbps is probably not enough. You will be able to watch with an internet speed between 10 and 100 Mbps. You can watch TV programs on your computer or on your TV with a set-top box. This box acts as a kind of adapter between your internet connection and your existing TV receiver, allowing you to view the Internet programs on your TV by analyzing the incoming signals.
IPTV is a bit more complicated for a broadcaster or telephone company. You need an advanced storage system for all the videos you want to use and a web-style interface that allows people to choose the programs they want. Once a viewer selects a program, it can encode, encrypt (so that only payers can decrypt it), place ads (especially in free programs) and stream online from one person (potentially) to thousands or millions of people simultaneously There are many things that need to be done, such as sending something, providing transfer. You also need to figure out how to do this to ensure a consistently high-quality video stream.
IPTV is generally offered in three different types. The first kind is called optional video (VOD video on demand) which is probably a system you already use. With a service such as Netflix (an online series-movie site), you select a TV show, series, or movie that you want to watch, pay and watch. A different type of IPTV is offered by some of the more entrepreneurial TV broadcasters in the world. In the UK, the BBC (British Broadcasting Corporation) takes last week’s programs online using a web-based video player called BBC iPlayer. Such services are sometimes called time-shifted IPTV, because you are watching ordinary, scheduled broadcasts at a time that is convenient for you. The third type of IPTV requires broadcasting of live TV programs being watched over the internet; therefore, it is also called live IPTV or IP simulation broadcasts. All three types of IPTV can work with your computer using an ordinary web browser or using a set-top box and a regular digital TV for better quality. All three can work either on the public internet or on a private network that works essentially the same (for example from your phone and your internet service provider).
Personalized Interactive TV
Traditional TV broadcasting means one-way multi-communication of information, but combining television and video with the Internet offers the opportunity to provide a much more interactive experience where information flows in both directions. So far, we have seen that people can vote for people they like at TV talent or song competitions simultaneously, but in the future, where TV shows are broadcast online, we can expect much more participation in the programs we watch. Instead of talking to a live audience of several hundred people in a studio, a host will be able to talk to thousands or millions of live audiences who can send instant feedback. Everyone who follows can ask questions and wait for the server to answer. Or maybe we can vote and change the course of the program as we want TV shows to go. Or we’ll be able to follow our chosen end or match our profile for numerous alternative finite films and series.
How IPTV Works
With traditional TV, programs are broadcasted into radio waves and transmitted from the air to a roof antenna in the house. The antenna converts the waves back into electrical signals and your TV set decodes them to produce audio and video. How does IPTV work?
Live programs are streamed when broadcasting, but pre-recorded programs and movies should be optionally selected and stored to stream. Some VOD services limit the number of programs they provide because of insufficient storage space, but this is a way to limit their service’s overall bandwidth and impact on the Internet. For example, if the BBC presented every program ever produced on the iPlayer that it was using, a significant portion of all of the UK’s Internet bandwidth could potentially slow down the network or any other net traffic by streaming television series and shows.
First, the TV program (previously recorded or captured live with a camcorder) must be converted to a digital format that can be delivered as a package using the Internet protocol. Sometimes the original program will already be in digital format; it will sometimes be in the form of a standard analog TV image (known as SD format) that requires an extra process (analog to digital conversion) to convert to digital format. Videos must be compressed (converted into smaller files) with valid bandwidth restrictions. Thus, they ensure smooth flow without buffering (the receiver may create periodic delays when generating incoming packets). In practice, it means that programs are encoded in MPEG2 or MPEG4 format. MPEG4 is a new video compression format that provides much better quality image transmission at similar bandwidth. It uses half the bandwidth of MPEG2 compression technique that transmits SD broadcasts. After the process is complete, ads must be added and the information must be encrypted.
When you browse a website, you create a temporary connection between two computers; so one biri pulls bil information from the other. Your computer (client) connects directly to an IP address that corresponds to the website you want to look at, pulling information from the other, usually a much more powerful computer (server). Between the client and the server, the client requests the files required to create the page you are looking for a short and intermittent conversation. Servers are usually very fast and powerful, so many clients can download information at the same time with very little delay. This is a one-to-one IP connection. It is known as a single-point IP connection.
However, in the case of video streams (while video programs play incoming streams while downloading them), clients place a much more simultaneous load on the server, causing unacceptable delays and buffering. Thus, with streaming, a different type of downloading process, known as IP multicasting, is used, where each packet leaves the server only once, but is sent to several different places at the same time; theoretically, this means that a server can send information to as many clients as easily as a single client. Thus, if all 1000 people are watching the World Cup final over the internet at the same time, there will be a single video packet stream sent from the server to 1000 customers using IP multicast. If the same TV provider offers a number of episodes simultaneously, and if some 1000 people decide to değiştir change channels için to watch it, they can effectively switch from one IP multicast group to another and start receiving a different video stream.
The worldwide geographic location of Internet servers makes it difficult to provide equal services to users in different countries. Therefore, IPTV providers often use synchronized, worldwide networks on servers known as content delivery networks, which hold copies of the same data; so people in the United States buy from the server in California, while people in Europe buy from Frankfurt.
When you receive a program as a video stream, you do not download it as an ordinary file. Instead, you download and play a file at the same time, and you’re ready to download the next stage of the file in a few seconds. None of the files are stored for too long. The video streaming process works because your computer (client) and the computer that receives data from the server are negotiated to do things like this. The Internet successfully connects computers around the world because they all agree to speak to each other in the same way, using pre-prepared technical procedures called protocols. Instead of using ordinary, standard, web-based protocols (technically switch to HTTP and FTP names) for downloading, simultaneous downloading in the video stream, such as Real Time Protocol (RTP Real Time Protocol) and Real Time Streaming Protocol (RTSP Real Time Streaming Protocol) and protocols adapted for playback. Multicast streaming, ie multicast, involves using the IP Group Membership Protocol (IPGP), which allows a server to broadcast to members of a group of customers (effectively many people watch the same TV channel).
Anyone with a computer and broadband internet connection can watch IPTV, but most of us don’t want to watch TV on a laptop. Therefore, the future of IPTV decodes the signal through receiver boxes that receive information from your internet connection (via an Ethernet cable or Wi-Fi) and uses high-quality, widescreen TVs to display videos. Receiver boxes are effective stand-alone computers that are programmed to do one thing. They receive video stream packets, decrypt them, convert them into video files (MPEG2, MPEG4, or whatever format they originally were) and then transmit them to the high-quality TV screen.
It is predicted that the future television technology will be largely composed of IPTVs. There is no reason why IPTVs should not become widespread as a result of the development of Internet technologies, the provision of broader bandwidth, and the increase in speed. It is very interesting to be able to watch the program, series, movies and make them in high quality at any time. With this technology, which is becoming widespread in our country, it is very pleasant to be able to download the episode episodes you missed from the internet and connect them to your smart TV with a USB and watch them with a single button. Fun and enjoyable cruises.
