Transponder
A transponder is a frequency converter which
receives TV and radio signals broadcast from
the earth, converts them and the 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
one transmission frequency. If a channel 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.
