- This documentation is outdated. Please check at the DVB wiki
- at https://linuxtv.org/wiki for more updated info.
+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.
- There's a section there specific for Avermedia boards at:
- https://linuxtv.org/wiki/index.php/AVerMedia
+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.
-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.
+ some countries employ a digital audio signal
+ embedded within the modulated composite analogue signal -
+ using NICAM signaling.)

-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

-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:
+* digitize the analogue video signal and make the resulting datastream
+ available to the data bus.
-* 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.
-
-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)

-
-* 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.

-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
-* /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/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.
-* /dev/dvb/adapter0/dvr0
-* /dev/dvb/adapter0/frontend0
+Depending on the card's feature set, the Device Driver API could also
+expose other device nodes:
-The dvr0 device node is used to read the MPEG2 Data Stream and
-the frontend0 node is used to tune the frontend tuner module.
+* /dev/dvb/adapter0/ca0
+* /dev/dvb/adapter0/audio0
+* /dev/dvb/adapter0/net0
+* /dev/dvb/adapter0/osd0
+* /dev/dvb/adapter0/video0
+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.
-Receiving DVB-T in Australia
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Receiving a digital TV channel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-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.
+This section attempts to explain how it works and how this affects the
+configuration of a Digital TV 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.
+On this example, we're considering tuning into DVB-T channels in
+Australia, at the Melbourne region.
-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:

+Channel 31 557.625 Mhz
+=========== ===========
+
+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::
# Data file for DVB scan program

# S Frequency Polarisation SymbolRate FEC
# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier

-
-The defaults for the transponder frequency and other
-modulation parameters were obtained from www.dba.org.au.
-
-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).
