The differences between IPTV and Web TV
In Turkey, one of the most popular methods of differentiating IPTV and internet television, Web TV, is that one has set-top box and the other doesn’t. I think that this is a serious mistake. Because Web TV has versions which work with a set-top box and Samsung developed new IPTV applications which work with a direct connection to the television instead of through a set-top box. In my opinion, one of the best methods of differentiating IPTV and Web TV is the infrastructure. The difference in the infrastructures of both systems is rather clear. Internet is a system which enables communication between two points where each data and package is sent one at a time. If you’re going to send visuals or do anything that deals with visuals you have small data packages. These data packages start communicating with the other computer, a handshake is performed. When the computer is defined the packages are sent one by one. After each package a verification of whether that package was received is sent back. After that verification if the package is not received yet or if there are serious problems involved, the package is sent again. Some of the packages sent being unreadable and new packages being required to be sent go by the name of quality of services.
If the quality of services is high, all packages reach the other side without issues. When I say all, it’s a bit of an exaggeration because as the service quality goes higher, the traffic goes down accordingly, because the aim is not sending faulty packages, but the proper ones. The second point in question is the traffic, which is irrelevant to the service quality of the service packages. Let’s go over an exemplary scenario. You have a computer and this computer sends video to 15 computers. The video needs to reach the other side and other computers need to confirm their connection to your computer and perform handshakes. After this mutual confirmation and the establishment of the protocol, 15 packages need to be prepared for one second of the video and sent to 15 people separately. Clearly this situation causes a serious amount of traffic. When the IPTV technology is in question, the computer sends all parts of the video to the router. The router relays the packages to anyone who wants to watch the video. As of now packages have been used only once in all internet technologies. For this reason a security system is in place, and since all packages go through the same internet environment, there exists an admissibility rate.
Needless to say, since the other media were founded upon one-on-one communication, security at security listening point was of foremost importance and admissibility was presenting a big problem. But the aim is admissibility now, to enable as many people to access the information as possible. You post the package once and it is fragmentized, multiplied and these new packages are made accessible to all computers by the router. As I stated before, this heavily decreases traffic. Let’s say that you have the live broadcast server of a television channel. The live broadcast server doesn’t have to send information to a great deal of people; it only sends information to the people who do. This new structure, which goes against the nature of the internet, will enable video to communicate in a more effective way. Not only will it enable that, but it will also allow broadcasting into the internet. Every time we talk about internet entering different industries, but this time it takes into effect the broadcasting and internet technologies side of the industry as well. This is the reason why IPTV takes a little more time to emerge. This is a crucial point. Many companies tried this in the past, one of which is Akamai. Akamai is a system with the aim of distributing information in the world. And they do it only with their own computers and infrastructure. It works in unison with the internet infrastructure. But of course it is not a natural infrastructure change like IPTV, but a forced one. Akamai’s accomplishments are really important, because in previous systems dealing with the distribution of information there aren’t any successful examples. They are slowly being formed. Because yet another important matter is the content managers.
