IPTV is a television transmission technology that uses the Internet Protocol (IP) for its function. Hence the abbreviation IPTV.
In addition, other IPTV protocols are used to optimize the viewing experience.
These would be:
Rapid Spanning Tree Protocol, or RSTP for short
This protocol is only activated when required or on request and enables time-shifted on-demand.
Internet Group Management Protocol, IGMP for short
This protocol is primarily active during a live stream and provides channel signaling.
IPTV- how does the technology work
I composed the data stream from IPTV of different data packets of the same size. These reach the recipient via the Internet.
Thanks to the IP address, which guarantees a simple assignment, which enables a targeted exchange of information between the sender, in this case the provider and the recipient (end device).
IPTV is interactive, so to speak, but digital TV is not.
Which video codecs are used in IPTV to compress the data?

The advantages of IPTV
Compared to digital TV or TV reception via cable network, IPTV offers clear advantages for the consumer:
The programs can be called up or saved at different times as required. (Timeshift TV or video on demand)
An almost unlimited number of participants can view the programs offered.

Internet technology – what are the basic requirements for interference-free IPTV?
Hardware and software are decisive for the image size of IPTV and the quality, just like the data transfer rate and bandwidth of the Internet connection.
ADSL meets the minimum requirements for IPTV. VDSL2, VDSL and / or ADSL2 + are of higher quality.
Regardless of which data connection you want to use for the use of IPTV, do not forget that at least a data transmission rate of at least 8 Mbit / s must be given, that HDTV with a resolution of 1080 × 1920 pixels is properly displayed.
IPTV vs. TV reception via cable
When receiving television via the BK network, all services and programs are each assigned to a special and, above all, fixed frequency range.
The precise assignment makes it possible for each individual service to be used by several subscribers. IPTV is operated via a DSL connection, but can also be used via radio networks or BK network.
Good to know: Whether simultaneous use is possible with IPTV depends on how high the bandwidth is. If this is not very high, it is only possible to use a service or a program.
