satellite provides for an innovative intercontinental contribution link service using a single Ka-band transponder with a
European footprint and a Ku-band transponder serving southern Africa. Contribution feeds can be transferred from one region to the other, and in one frequency band to the other,

A single satellite link can span a huge distance that would take a terrestrial link through many countries and commercial operators. The satellite operator provides a single point of accountability whereas establishing a link and resolving service interruptions with fibre can prove difficult,

Ka-band provides for a smaller contribution uplink dish size (typically 1.8m compared to a minimum of 2.4m using Ku-band) and it can also be used as a backup for the DTH uplink itself or when a full DTH uplink antenna (typically 9m) cannot be accommodated at the client's studio.
94:
Monitoring of the signal allows for fast and effective changes before problems affect the service. E.g. uplink power may be automatically increased during adverse weather conditions.

Duplication of active components in the transmission and reception sites, and in-orbit backup satellite capacity provides a fully redundant contribution connection.

and live video streaming specialists, LiveU, launched an integrated hybrid end-to-end video contribution and distribution system for broadcasting live events using

Satellite operators and third party agencies provide satellite contribution links for the occasional or regular use of the client broadcasters.
