Short technical lexicon
Transponder
A transponder is a satellite transmitter which transmits TV and radio
signals. A satellite has several transponders.
Analogue transponders transmit only one TV channel and possibly
several radio channels on their transmit frequencies.
Digital transponders simultaneously transmit several TV and several
radio channels on their transmit frequencies. When a channel provider
broadcasts several TV channels via a digital transponder, this is
referred to as the channel package of the channel provider. The terms
"digital transponder" and "channel package," therefore have the same
meaning.
Video bit rate
The video bit rate describes the quantity of data of the digitised video
signal that is transmitted per second.
Viterbirate
The viterbirate (code rate, error rate) characterises the type of error
protection used by the channel provider. The DVB standard stipulates
the following values: 1/2 -2/ 3 - 3/4 - 4/5 - 5/6 6/7 - 7/8.
