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.
