The technical principle in three steps
A video stream is encoded, transported across the internet as data packets, then decoded by an app or a set-top box at the viewer's end. This principle applies to both live broadcasts and video on demand.
Operators offering connected television manage this transport over their own controlled network, which lets them guarantee a certain quality of service, unlike a stream carried over the public internet without congestion control.
Live, catch-up and video on demand
IPTV covers three distinct uses: live, which retransmits a programme as it airs; catch-up, which lets viewers watch a programme again afterwards; and video on demand, which gives access to a catalogue available at any time.
Belgian public broadcasters' apps often combine all three for their own programmes, within the rights they hold over their production.
Why quality depends as much on the network as on the service
The stability of an IPTV stream depends heavily on the local internet connection: available bandwidth, latency, Wi-Fi stability and the number of devices using the network at the same time. An otherwise legitimate service can therefore appear faulty because of an insufficient connection.
That is why two households using the same service can have very different experiences: the determining factor is often the quality of the local internet connection, not the service itself.
Frequently asked questions
01Does IPTV automatically mean piracy?＋
No. IPTV only describes a method of transporting television over the internet. Legality depends on the rights covering the content delivered, not on the technology itself.
02How is it different from satellite television?＋
Satellite broadcasts a radio signal from space to a dish; IPTV carries data over an internet network, managed or public, to an app or set-top box.
03Why does my legal IPTV stream sometimes buffer?＋
Most often because of insufficient internet bandwidth, Wi-Fi congestion, or too many devices connected to the network at the same time.
