What is IPTV?

The IP is similar to that of used in our internet connections.
It works in contrast to traditional television programming that uses cable networks or satellite signals.
IPTV works with the help of the internet in a more efficient way as compared to conventional media.
How IPTV work?
Unlike the traditional methods of broadcasting, IPTV works with the help of digital signals that are conveyed over the internet.
However, in conventional television, analog signals are used with the help of radio waves that travel through the air.
The following are some steps that a TV program has to complete before streaming a program or video on IPTV.
For streaming a program on IPTV, whether live or recorded, the analog signals of program converted into digital signals by using the analog to digital converter and deliver the signals in packets.
They also need to be compressed to lessen the size and allow the video to play smoothly without buffering. However, these programs or videos are converted either in MPEG4 or MPEG2.
After this, ads are inserted, and all the information has to encrypt to finalize the preparation.
IPTV stream live programs as they are broadcasting while the prerecorded movies and TV programs are compressed and stored for streaming at a later time as an on-demand program.
However, due to limitations in bandwidth, the storage is limited to reduce the impact on the internet.
Web streaming activities take place with the help of IP multitasking.
It is a type of data downloading available in packets that are sent from servers to a different location at the same time.
This works in opposition to simple web browsing where data is shared between client and server simultaneously using IP unicasting.
While IP multitasking empowers the server to handle multiple requests at the same time for the same video.
Moreover, IPTV service providers use content delivery networks that are capable of keeping the mirror copy of the same data and provides reliable data delivery from different locations around the world.
For watching the programs by using IPTV, users have to use a set-top box that is capable of receiving the digital signals from the internet.
Users can also watch streaming on their computers, but many people do not like to use their computers as television.
Set-top boxes are eligible to decode the signals and stream the high definition videos on your TV.
