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
The data stream from IPTV is composed of different data packets of the same size. These reach the recipient via the Internet. Thanks to the IP address, which guarantees a clear 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.

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, on the other hand, is operated via a DSL connection, but can also be used via radio networks or BK network.
Good to know: Whether or not 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.
