The strong development of the global Internet has contributed to the birth of a completely new and promising form of television. It is Internet TV (IPTV).

Although it was born more than a decade ago, it can be seen that IPTV can hardly grow as expected because in the past the infrastructure and network bandwidth conditions have not allowed this new type of television to develop. all advantages. Therefore, IPTV still has to face with traditional TV and cable TV.

But in recent years, the Internet has made great progress. The most notable is the popularity of broadband networks with faster connection speeds. In some countries like South Korea fiber optic cable has been pulled to every house. This is the platform that helps IPTV start to develop strongly.

What is IPTV?

IPTV stands for 'Internet Protocol TV' and is translated as 'Internet Television'. This is a technology that enables the transmission of television programs through the broadband Internet.

Instead of receiving a traditional TV signal or satellite signal or via cable, IPTV allows the TV to be directly connected to the receiver's Internet line. It can be seen that television service has been integrated directly with Internet connection service.

There are two main methods of receiving Internet television signals. First, use a computer connected to an IPTV television service to receive signals and then convert them into traditional TV signals on standard TVs. Second, use a signal converter (set top box). In fact, this signal converter only acts as a PC as in the first method. Of course, with the development of technology, there will definitely be TV products that can connect and receive TV signals directly from the Internet.

Besides, users can also witness the development of wireless IPTV television. This is no longer a future forecast, but has become a simple reality of wireless Internet connection. IPTV is also wireless.

Advantages of IPTV

Multi-service integration . On an Internet connection, IPTV users can use many different services simultaneously such as Internet access, television, fixed and mobile phones, VoIP (Voice over Internet Protocol) . to bring give users the convenience of using it.

High interaction . IPTV gives users the experience of watching highly interactive and personalized television. For example, an IPTV service provider can integrate an interactive tutorial program that allows viewers to search for TV program content by title or actor name. Or the service provider can deploy picture-in-picture (picture-in-picture) functionality that allows users to watch multiple channels at once. Users can also use the TV to access other multimedia content on a PC such as a picture or video or use a mobile phone to control the TV at home to record a favorite program. .

Another interactive method that IPTV service providers can deploy is to provide information that viewers request directly during the program. For example, users can receive information about the team they are watching on the screen for example.

In fact, the high similarity can appear in other types of digital television such as satellite or cable television. But to deploy, it is necessary to have an interactive connection between the transmitter and the receiver. This is something that satellite TV and cable do not have. In order to deploy, these two forms of television must be combined with other network infrastructures such as Internet or mobile phones.

IP switching technology . Most users are unaware that cable and satellite television often send all the signals of every channel at the same time to allow users to switch channels instantly as we see them. This results in a waste of necessary bandwidth.

IPTV uses IP switching technology to eliminate this restriction. All television program data is stored in a central location and only the channel data that the user requires is considered to be transmitted. This will allow service providers to be able to add more services to IPTV because bandwidth is no longer a problem to deal with.

Family network . Connecting to the Internet in the home not only has TV but also other PCs. This will allow users to use the TV to access multimedia content on PCs such as digital photos, videos, surf the web, listen to music . Not only that, but some TV screens are now available. Integrated ability to operate like a normal TV. All links will become a perfect home entertainment network.

Video on demand - Video on Demand (VOD) . VOD is the most anticipated interactive feature in IPTV. This feature allows viewers to request to watch any television program they like. For example, a viewer who wants to watch a movie that has existed a few years ago only needs to do a search and take the time to watch or record it later.

Maximize the TV program . VOD said that is exactly a part of this advantage. This is a feature that users will enjoy most in IPTV because it allows them to control the maximum of television programs.

No longer passive to see what service providers broadcast like in traditional television or satellite, but now users will experience the ability to control the maximum content they want to see. With VOD, users can select favorite programs or burn it to disc for viewing later.

As a result, the IPTV remote control device will have full functionality such as controlling a player. While watching a program if you encounter a segment or users can rewind to playback, stop playing the program or fast forward . This is also simple because the content is provided only on demand. of the viewer, not as wide for everyone as a traditional television.

High quality television HD . The trend of high quality content is now available. Thanks to a broadband connection, it can be said that in the future not far from IPTV, only high quality television will be broadcast. This means that users will enjoy programs with high picture and sound quality.

Disadvantages of IPTV

The 'critical' disadvantage of IPTV is the very high data loss and signal transmission delay. If the user's network connection is not really good and there is not enough bandwidth needed, watching the program will be very jerky or the channel switching can take a lot of time to download. In addition, if the service provider's server is not strong enough, when the number of viewers access to the east, the deterioration of service quality is also very easy to understand. This is not really the disadvantage of IPTV but the whole web world.

But a world in which every device can be connected is one of the goals that the world is aiming for. IPTV television is also part of this trend. Internet technology has been increasingly developed, pushing the connection bandwidth higher, helping IPTV overcome the above disadvantages and turning it into a television technology of the future.

The deployment of IPTV television can be considered an inevitable trend in our country because in recent years VNPT Group has strongly promoted the development of broadband Internet with the aim of bringing high-speed Internet to each house. This is an essential basis to promote the development of new value-added services on the Internet and IPTV as one of the measures.
