3 TV over IP

The architecture of IP networks for delivering linear broadcast TV services looks similar to some traditional delivery networks, being a type of secondary distribution network. The major components are:
  • Head-End (HE) – where feeds are acquired and ingested.
  • Core transport network – where IP packets route from one place to another.
  • Central VoD Nodes – where the video servers reside.
  • Regional VoD Node – where access network elements such as the DSLAMs are aggregated.
  • Access network – which takes the data to the home – together with the home gateway and the user’s STB.
  • Inhome network – where the STBs access to TV channels.

End-to-end TV service network architecture

The whole network, however, is controlled, managed and maintained as a single service.
