Channel Package
For the most part, the channel package contains several TV and radio channels. Each channel package is fixedly assigned to the transmit frequency, the polarisation (horizontal or vertical), the symbol rate and the Viterbi rate or error rate.
Symbol Rate
The symbol rate describes the amount of data transmitted per second. The symbol rate is measured in MSymbole/s and equal to the amount of symbols coming in per second.
Video Bit Rate
The video bit rate describes the amount of data of the digitalised video signal transmitted per second.
Viterbi Rate
The Viterbi rate (Code rate, error rate) characterises the type of error protection utilised by the programme provider. The DVB standard determines the following values: 1/2 - 2/3 - 3/4 - 5/6 - 7/8
