Using the Digital TV Framework
==============================
February 14th 2006
Introduction
~~~~~~~~~~~~
.. note::
One significant difference between Digital TV and Analogue TV that the
unwary (like myself) should consider is that, although the component
structure of DVB-T cards are substantially similar to Analogue TV cards,
they function in substantially different ways.
This documentation is outdated. Please check at the DVB wiki
at https://linuxtv.org/wiki for more updated info.
There's a section there specific for Avermedia boards at:

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:
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 frames
per second in Europe) rasterised using an interlacing technique.
Interlacing takes two fields to represent one frame. Therefore, an
Analogue TV card for a PC has the following purpose:
* Tune the receiver to receive a broadcast signal
* demodulate the broadcast signal
* demultiplex the analogue video signal and analogue audio
signal. **NOTE:** some countries employ a digital audio signal
embedded within the modulated composite analogue signal -
NICAM.)
* digitize the analogue video signal and make the resulting
datastream available to the data bus.
* demultiplex the analogue video signal and analogue audio
signal.
The digital datastream from an Analogue TV card is generated
by circuitry on the card and is often presented uncompressed.
For a PAL TV signal encoded at a resolution of 768x576 24-bit
color pixels over 25 frames per second - a fair amount of data
is generated and must be processed by the PC before it can be
displayed on the video monitor screen. Some Analogue TV cards
for PCs have onboard MPEG2 encoders which permit the raw
digital data stream to be presented to the PC in an encoded
and compressed form - similar to the form that is used in

The purpose of a simple budget digital TV card (DVB-T,C or S) is to
simply:
* Tune the received to receive a broadcast signal.
* Extract the encoded digital datastream from the broadcast
signal.
* 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.

Getting the card going
~~~~~~~~~~~~~~~~~~~~~~
In order to fire up the card, it is necessary to load a number
of modules from the DVB driver set. Prior to this it will have
been necessary to download these drivers from the linuxtv CVS
server and compile them successfully.
The Device Driver API for DVB under Linux will the following
device nodes via the devfs filesystem:
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/dvr0
* /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/osd0
* /dev/dvb/adapter0/video0
The primary device nodes that we are interested in (at this
stage) for the Avermedia DVB-T are:
The ``/dev/dvb/adapter0/ca0`` is used to decode encrypted channels. The
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.
* /dev/dvb/adapter0/dvr0
* /dev/dvb/adapter0/frontend0
Receiving a digital TV channel
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The dvr0 device node is used to read the MPEG2 Data Stream and
the frontend0 node is used to tune the frontend tuner module.
This section attempts to explain how it works and how this affects the
configuration of a Digital TV card.
On this example, we're considering tuning into DVB-T channels in
Australia, at the Melbourne region.
Receiving DVB-T in Australia
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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:
The frequencies broadcast by Mount Dandenong transmitters are,
currently:

=========== ===========
The Scan utility has a set of compiled-in defaults for various
countries and regions, but if they do not suit, or if you have
a pre-compiled scan binary, you can specify a data file on the
command line which contains the transponder frequencies. Here
is a sample file for the above channel transponders:
The digital TV Scan utilities (like dvbv5-scan) have use a set of
compiled-in defaults for various countries and regions. Those are
currently provided as a separate package, called dtv-scan-tables. It's
git tree is located at LinuxTV.org:
::
https://git.linuxtv.org/dtv-scan-tables.git/
If none of the tables there suit, you can specify a data file on the
command line which contains the transponder frequencies. Here is a
sample file for the above channel transponders, in the old "channel"
format::

The defaults for the transponder frequency and other

When Scan runs, it will output channels.conf information for
any channel's transponders which the card's frontend can lock
onto. (i.e. any whose signal is strong enough at your
antenna).
Nowadays, we prefer to use a newer format, with is more verbose and easier
to understand. With the new format, the "Seven" channel transponder's
data is represented by::
Here's my channels.conf file for anyone who's interested:

exists into each channel's transponders which the card's frontend can
lock onto. (i.e. any whose signal is strong enough at your antenna).
