Using the Digital TV Framework

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This documentation is outdated.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 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

If none of the tables there suit, you can specify a data file on the

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).
