Transponder
A transponder is a frequency converter which receives TV and radio signals broadcast from the earth,
converts them and then rebroadcasts them to the earth at a different frequency. A satellite has several
transponders.

Analogue transponders transmit only one TV channel and possibly multiple radio channels on a single
transmission frequency.

Digital transponders simultaneously transmit several TV and several radio programmes on a transmission
frequency. If a programme provider is broadcasting several TV channels via a digital transponder,
we refer to the provider's channel package. The terms “digital transponder” and “channel package”
have the same meaning.

Video bit rate
The video bit rate describes the quantity of data from the digitised video signal that is transmitted per
