DiSEqC™
DiSEqC™ (Digital Satellite Equipment Control) is a communication system between a satellite receiver (master) and the peripheral satellite components (slaves), such as LNBs,
It is a single
DiSEqC™ components
If DiSEqC™ switching matrices are cascaded, the master receiver must transmit the DiSEqC™ signal several times, so that all DiSEqC™
These days, DiSEqC™ components (slaves) must be reverse compatible, i.e. respond to the analogue switching criteria from receivers that are only equipped with H/V and 22 kHz control signals.
A DiSEqC™ switching matrix will work with analogue switching critiera until the DiSEqC™ command from the master is received. All analogue switching criteria are then ignored.
DVB MPEG-2
DVB is the abbreviation for Digital Video Broadcasting.
EB/NO ratio
The EB/NO ratio is a measure of the signal to noise ratio of a digital signal. The value is not identical to the C/N value familiar from analogue reception technology. At EB/NO values below 5 dB no reception is normally possible.
FEC
FEC is the abbreviation for Forward Error Correction. The FEC error rate corresponds to the Viterbi rate.
OTR
One Touch Recording
PID
The PID (Packet IDentification) number is an identification number for video signals and audio signals in the digital data stream of DVB-
