EchoNAV Version 2.2
A frequency range (3.70-4.20 GHz) used for satellite
broadcasts.
Both names are used for these modules. These modules are
PCMCIA cards with a slot in which you can insert a smart
card.
A DVB standard which defines the software and hardware
requirements for condition access systems.
A system which is used by service providers to control the
subscriber's access to certain services, programs and events
like Pay TV.
A standard through which it is possible to let a DiSEqC
compatible receiver send a signal over the RF cable to a
switching device to switch between different LNBs or dishes.
DiSEqC uses the 22kHz signal to control the switching
device.
A electronic program guide that comes with a broadcast.
Note that every station fills the EPG differently or not, so
differences in the EPG are not necessarily receiver errors.
Is an invisible part of a broadcast. that can correct possible
errors in the reception of the satellite signal.
A dish antenna that is pointed at one particular satellite.
An unscrambled broadcast which you can view without
additional payments to a service provider.
A frequency band is a range of frequencies which are
dedicate to a certain usage. In the satellite area, commonly
known bands are the C-band and the Ku-band.
In the satellite industry, horizontal is used to indicate the
direction in which the received signal is polarized. Normally
you will find that it is abbreviated as H.
A frequency range (10.70-18.00 GHz) used by most
European TV satellites.
A device behind the feedhorn which processes the signal
into a format which is understood by the receiver for further
processing
A LNB with an integrated Feedhorn. So the LNBF comes as
one single unit.
Multi channel system broadcasting many copies of a film
with staggered start times so a complete film is always
available to a viewer with a short waiting period.
With respect to the receiver, a network (also known as a
bouquet) is a set of programs that is offered by a single
service provider.
USA video standard with image format 4:3, 625 lines, 60 Hz
and 4 MHz bandwidth with a total of 6 MHz video channel
width.
European video standard with image format 4:3, 625 lines,
50 Hz and 4 MHz bandwidth with a total of 8 MHz video
channel width.
MPEG-2 transmits the audio and video information in so-
called packages. Each package has an identifier (PID)
present which tells the receiver what to do with the received
information. Satellite receivers use normally four types of
PID, these are VPID (Video PID), APID (Audio PID),
Program Clock Reference (PCR PID) and data PID (EPG).
