Hiya Q

I assume from your comments about the devices in /dev/dvb that your hardware is correctly detected and working. If this is not the case then you need to take a couple of steps back and tell us which dvb card(s) you have, kernel version, patches applied etc.

====== Step 1
Once your hardware is correctly detected. The first step is to perform a channel scan which will yield a list of channels available in your area. Channel scanning is performed by a dvb-utility called scan (this is in the dvb-apps module in CVS) . You will need to supply scan a config file which tells it where to fine one of the multiplexes available in your area. If you are lucky there will be an existing config file for your transmitter, look in dvb-apps/util/scan/dvb-t/uk-{name of your transmitter}.

====== Step 1 .1
If you dont have an existing channel config file (like i didnt + I will add to mailing list asap oops) you will need to create one manually. Refer to
http://www.ofcom.org.uk/static/reception_advice/index.asp.html
and choose the area you are in, then click on the line ' Digital Transmitter Information' and finally choose the transmitter you are using. This will take you to a page which details the frequency and offsets for the multiplexes ( a multiplex is a collection of digital TV channels) available to you.
e.g. For Knock Moor
Multiplex 1 BBC
Channel 34
Offset +
ERP 1.0
Multiplex 2 Digital 3&4
Channel 30
Offset +
ERP 1.0
Multiplex A SDN
Channel 53
Offset 0
ERP 1.0
Multiplex B BBC
Channel 57
Offset +
ERP 1.0
Multiplex C Crown Castle
Channel 60
Offset 0
ERP 1.0
Multiplex D Crown Castle
Channel 56
Offset -
ERP 1.0

====== Step 1 .2
The next step is to construct the config file from this information.
create a new file called uk-{transmitter name} in the dvb-t sub dir of scan.

In my case I created uk-Caradon
# UK Caradon
# Caradon is channel 34 = Multiplex 1 BBC1 = 578MHz with no +- offset
# refer to
# http://www.ofcom.org.uk/static/reception_advice/digital_trans_guide/show_transmitter.asp-siteID=65.html
#
# for other uk digital transmitters look at
# http://www.ofcom.org.uk/static/reception_advice/index.asp.html
#
# To convert from channel No. to frequency in MHz
# Multiply by 17
#
# Peter Henderson.
# www.starjar.com
#
#
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 474000000 8MHz 1/2 NONE QAM16 2k 1/32 NONE

If your transmitter has an offset you will need to add/subtract 167kHz from the frequency
As for the the FEC (the 1/2 field) I had to guess until it worked, as I couldnt find a source of information on that. The same applies for QAM16 you may have to try QAM64. The rest of the parameters are fix as far as I know in the UK.

====== Step 2
Once you have a config for your transmitter. Its time to scan
./dvbscan dvb-t/uk-Cardon > channels.conf

Which will output something like
[root@broadmead scan]# ./dvbscan dvb-t/uk-Caradon > channels.conf
scanning dvb-t/uk-Caradon
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

====== Step 3
Now you have a channels.conf file its time to test.
This only works if you have a recent version of the dvb-apps (please correct me here people) .
Open a console and run
[root@broadmead szap]# ./tzap -c /home/peter/email.conf "BBC ONE"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/home/peter/channels.conf'
tuning to 578000000 Hz
video pid 0x0258, audio pid 0x0259
status 00 | signal 10c4 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal 10c4 | snr c7c7 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 10c4 | snr c4c4 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 10c4 | snr b7b7 | ber 00008cf0 | unc 00000000 | FE_HAS_LOCK

This tunes the DVB card to a station, FE_HAS_LOCK means it has tuned successfully.

====== Step 3 .1
(Untested Instructions please help)
Open another console and run (while tzap is running in the other console)
dvbstream -c channels.conf | mplayer -

Phew

I hope this helps

OK I 'm a total n00b I admit it! I'm sorry... But I just got round to
taking a look at The DVB tools. Unfortunately I am sorry to say thatI I
have found it all deeply confusing.

I have all of the required dvb modules listed in /dev/dvb. In there I
have exactly three devices listed which are: demux0, dvr0 and net0.

To begin with I'm not even sure what these three devices are - insomuch
as which of these would give me any kind of TV output? I had a look at
tzap, since I understand that this is what I would use for dvb-t TV
viewing, but like many things in Linux it seemed utterly cryptic.

I live in Newcastle upon Tyne in the UK - could anyone offer me a
working example of how to use these tools to generate a valid config
file for my device - and also suggest what I need to do next after
having made this to get DVB working on my box?

I had a look at some of those things in the supplied tools and some of
them look like there are executables that need to be run at boot time if
DVB TV is to function correctly?

It all seems highly cryptic.

I'm using KDE and Gentoo with a 2.6.7 kernel if that is of any
significance.

My TV card is a WinTV Nova-T.

Any at all input would be appreciated.

What I need is some docs that lay out how to get this working in clear
step by step instructions. (It's the only way I managed to set up
Gentoo) I don't mind reading the docs providing they are clear, but
those provided with the driver seem anything but clear. I have read all
over the site looking for simple easy to follow instructions on how to
set up this specific card - but what I found either didn't relate to me,
or it read like a Martian technical manual.

Please advise.

GJ

Thanks in advance.
