Assumptions and Introduction
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It is assumed that the reader understands the basic structure
of the Linux Kernel DVB drivers and the general principles of
Digital TV.
One significant difference between Digital TV and Analogue TV
that the unwary (like myself) should consider is that,
although the component structure of budget DVB-T cards are
substantially similar to Analogue TV cards, they function in
substantially different ways.
The purpose of an Analogue TV is to receive and display an
Analogue Television signal. An Analogue TV signal (otherwise
known as composite video) is an analogue encoding of a
sequence of image frames (25 per second) rasterised using an
interlacing technique. Interlacing takes two fields to
represent one frame. Computers today are at their best when
dealing with digital signals, not analogue signals and a
composite video signal is about as far removed from a digital
data stream as you can get. Therefore, an Analogue TV card for
a PC has the following purpose:
* Tune the receiver to receive a broadcast signal * Tune the receiver to receive a broadcast signal
* demodulate the broadcast signal * demodulate the broadcast signal
* demultiplex the analogue video signal and analogue audio * demultiplex the analogue video signal and analogue audio

* digitize the analogue video signal and make the resulting
datastream available to the data bus.
The digital datastream from an Analogue TV card is generated .. note::
by circuitry on the card and is often presented uncompressed.

* Make the encoded digital datastream (MPEG2) available to
the data bus.
The significant difference between the two is that the tuner
on the analogue TV card spits out an Analogue signal, whereas
the tuner on the digital TV card spits out a compressed
encoded digital datastream. As the signal is already
digitised, it is trivial to pass this datastream to the PC
databus with minimal additional processing and then extract
the digital video and audio datastreams passing them to the
appropriate software or hardware for decoding and viewing.

In order to fire up the card, it is necessary to load a number The Device Driver API for DVB under Linux will the following
of modules from the DVB driver set. Prior to this it will have device nodes via the devfs filesystem:
been necessary to download these drivers from the linuxtv CVS
server and compile them successfully.
Depending on the card's feature set, the Device Driver API for
DVB under Linux will expose some of the following device files
in the /dev tree:
* /dev/dvb/adapter0/audio0
* /dev/dvb/adapter0/ca0
* /dev/dvb/adapter0/demux0 * /dev/dvb/adapter0/demux0
* /dev/dvb/adapter0/dvr0 * /dev/dvb/adapter0/dvr0
* /dev/dvb/adapter0/frontend0 * /dev/dvb/adapter0/frontend0
The ``/dev/dvb/adapter0/dvr0`` device node is used to read the MPEG2
Data Stream and the ``/dev/dvb/adapter0/frontend0`` device node is used
to tune the frontend tuner module. The ``/dev/dvb/adapter0/demux0`` is
used to control what programs will be received.
Depending on the card's feature set, the Device Driver API could also
expose other device nodes:
* /dev/dvb/adapter0/ca0
* /dev/dvb/adapter0/audio0
* /dev/dvb/adapter0/net0 * /dev/dvb/adapter0/net0
* /dev/dvb/adapter0/osd0 * /dev/dvb/adapter0/osd0
* /dev/dvb/adapter0/video0 * /dev/dvb/adapter0/video0
The primary device nodes that we are interested in (at this The ``/dev/dvb/adapter0/ca0`` is used to decode encrypted channels. The
stage) for the Avermedia DVB-T are: other device nodes are found only on devices that use the av7110
driver, with is now obsoleted, together with the extra API whose such
devices use.

I have no experience of DVB-T in other countries other than
Australia, so I will attempt to explain how it works here in
Melbourne and how this affects the configuration of the DVB-T
card.
The Digital Broadcasting Australia website has a Reception
locatortool which provides information on transponder channels
and frequencies. My local transmitter happens to be Mount
Dandenong.
The frequencies broadcast by Mount Dandenong are:
