When people talk about IPTV or Internet TV, because of the similarity between digital television and Internet TV, many people would not be able to see what they want from their programs and whatever they like with receivers and TVs without the need for a dish that receives signals And frequencies of satellite broadcasting.
IPTV or IPTV is a system based on the provision of digital television broadcasting over the Internet via computer networks and the Internet, which often operate using broadband infrastructure and broadband lines. In general, the difference The main difference between IPTV and traditional television systems is the use of computer and Internet networks, rather than traditional broadcasting methods, to deliver visual material to viewers.
Experts believe that the advantage of Internet TV service is the provision of video on demand, "in conjunction with VOIP" with the ability to access the Internet, and allows some of the providers of this service to the viewer to choose what he wants to see during A low latency and low cost. It has the ability to record and display what the user can not see, and to watch the channel and record another program via another channel on the same receiver.
The last 10 years have witnessed the birth of HDTV technology, which enables the presentation of the high-definition video content transmitted via satellite, and has played a role in accelerating the development of the television broadcasting arena. The latest development of this development is the emergence of Internet TV technology « IPTV ».
IPTV analysts say IPTV is the new direction for the future of television broadcasting, where a small receiver is used to connect over Internet networks. This device is responsible for regrouping data packets sent by the service provider and then decrypting them for On the contents of the video being transmitted, and it may be possible to include this device in the computer to perform this function, but it will then require the computer to remain in the operating position so that there is no interruption in the work, and the use of it via computers is a violation of privacy and copyright of channels and providers of cheek At present.
The content of all the TV channels goes through a system to monitor and encrypt such content when necessary, and is usually based on MPEG-2 format or one of the supported video playback formats. Digital content is then divided into groups and packets of data transmitted using IP, These packages all data types such as image, sound, and other data, as well as video contents.
Instead of relying on more than one network and using more than one LNB on the receiver, all the data they require will be available via IPTV, which will replace other satellite networks soon. Quality Assurance (QoS) or "quality of service" which controls the transmission of the channel to prevent any delay in the access of the content or interruption of the TV signal.
The new infrastructure for high-speed Internet service providers, such as satellite or fiber-optic communications, supports the spread of IPTV as it offers a fairly fast and stable Internet connection.
Mohammed Al-Luhaidan, one of the users of this service, said: "I participated in this service during my study abroad for small sums. The most important thing that attracted me was the possibility of using the video on demand feature, which enabled me to choose and watch the video content through a wide library of videos and programs All kinds of time and what I want ».
He added that this service provides the possibility of recording and retrieving programs that were not seen at the time of presentation, and was able to access the re-run of television programs during the previous several days such as serials and games and others, as well as containing an electronic program guide, which makes it easy to know what can be seen before Display it by days by providing a date of presentation, type of program and classification by the age group of the viewer, and a brief description of the film or program displayed.
Abdul Rahman al-Makri, a researcher in the field of technology, said that the Internet TV service is facing some obstacles. It is dependent on the Internet as a means of use, meaning that any interruption or malfunction in the internet connection stops the service. However, the new infrastructure of high-speed Internet service providers, Satellite or fiber optic supports its spread as it offers a fast and fairly stable Internet connection.
"One of the obstacles that affects the spread of the service is also the issue of digital rights management (DRM), and how the service provider restrict access or access to Internet TV by anyone except subscribers, has recently spread many devices Of Internet-based satellite decoding, as well as how to restrict users' ability to copy and distribute content through IPTV receivers, most of which are protected by copyright.
