Hello all,

I've setup the http://mercurial.intuxication.org/hg/scan-s2/ repository with
scan utility ported to work with Igor's S2API driver.
Driver is available here: http://mercurial.intuxication.org/hg/s2-liplianin/

Special thanks to Igor for his driver and for szap-s2 utility that I've used
as a reference for scan-s2.
Thanks also to someone from the net that posted his changes to scan utility
that allowed it to work with uncommitted diseqc.

Pay attention to parameters (see README as well), I've added some and
removed some that I don't think are needed.

Scan results gave me the same channels as with multiproto driver on all my
satellites, so that confirms also that Igor's driver is working well.

I didn't yet tested the output files with szap-s2 or with VDR, don't have
time right now.
Please test and let me know if changes are needed.

I have only Twinhan 1041 card (stb0899), so I can't test it with DVB-T,
DVB-C and ATSC standarts, but theoretically it should work.

Enjoy,
Alex.

Thank you for this usefull tool. I have tried them with TT S2-3200.
It works with s2-liplianin.
Some question
Is it possible to implement in vdr-dump
1. Options for Modulation (MN where N=2  is QPSK if DVB-S and N=2 for
QPSK and N=5 for 8PSK)
2. Options for FEC. As I know cx24116 can't FEC AUTO for DVB-S2
3. ROLLOFF?
4. CAID dump.  http://arvdr-dev.free-x.de:8080/freex-dvb-apps/rev/47e9dbb968fc
5. Channel Name encoding to UTF.
http://arvdr-dev.free-x.de:8080/freex-dvb-apps/rev/55bf7441a602

Thx a lot
Oleg Roitburd

Hi Oleg,

I had plans to do most of the things you've requested, but had no time and
decided to release the utility without those options so it will be tested.
I'll send an update when it will be ready.

A question about modulation. Can you point me to a place that describe what
modulation number N means what?
"man 5 vdr" lists the options, but its impossible to understand the mapping:
"M   Modulation (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 16, 32, 64, 128, 256,
512, 998, 1024)"

FEC you can specify in the frequency file as "AUTO", "1/3", "2/3" and so on.
I'll update README to make it clear. All frequency files samples show that
option.

i have seen, that FEC will be set if FEC is in initial file.
If transponder was found via NIT it will be not set

Thanks. I'll use it in the dump.

Yeah, it was my change since I saw NIT specifying incorrect FEC for a
channel that was in my frequency list already!
I'll probably change it so NIT will be considered as the correct info unless
frequency list include non-AUTO value.
This way it will be possible to overwrite values or rely on network
announcements if you want full automatic behavior.

Hi all,

Some updates for scan-s2:
- Frequency files parameters that can specify AUTO are now optional, not
required to appear in the file. See README.
- Added ROLLOFF and modulation specification for DVB-S format. See README.
- Fixed usage of -n (network search) switch. NIT messages will not add new
transponders by default now, so add -n if you really want it.
- NIT messages will not update existing transponders any more. After seeing
several bad NIT messages that caused to miss channels I think that will be
better that way.
- Added dumping of modulation and rolloff to VDR format file. The program
queries the driver after successful tuning to get real parameters of the
channel. Currently the driver do not return real values except for FEC, so
if you specify AUTO values the output file will not have the real rolloff
and modulation values. Igor said he will look at it.
- Added CAID dump to VDR file format, see "-x -2" switch.
- "-x XXX" switch opeation is fixed. Don't know who might want to use it
after real CAID dump (option -2) and dump zeroes to CAID (option -1) is
available.


Currently my TODO list include UTF channel names encoding. If you think of
something else, please let me know and I'll try to add.

Please test the latest version of scan-s2 from:
http://mercurial.intuxication.org/hg/scan-s2/

Enjoy,
Alex.

Приветствую, Alex

thanks for you work. But for me scan-s2 works strange - scan-s2 couldn't find a lot of dvb-s2 & dvb-s channels from Astra
19e

I have a lot of copies of 4th channels with different freq

the full log in 
http://paste.org.ru/?g0b0pn

I think scan-s2 is scanning only current 11914 transponder (in my case). With this transponder I worked with vdr before
scan2 started.

That's definitely looks strange. Can you check your driver output to see if
it reported some errors?
Looks like your driver didn't tune to other frequencies at all.

What card do you have?
Did you exit from VDR when you scanned?

Try also adding "-k 3" to the command line.

Hi, again.
Some improvements were made. Changed frequency scan file from above to
the one below and a few more parameters were added by scan-s2.

 # 30W
S 12012000 H 30000000 3/4 AUTO 8PSK
S 12052000 H 30000000 3/4 AUTO 8PSK
S 12092000 H 30000000 3/4 AUTO 8PSK

The resulting scan:

(null) - [000-0065];:12012:hS1C34M5:30W:30000:4097:4098:4100:100:101:0:0:0

(null) - [006-006b];:12012:hS1C34M5:30W:30000:4145:4146:4100:100:107:0:0:0

(null) - [00b-0070];:12012:hS1C34M5:30W:30000:4185:4186:0:100:112:0:0:0

Notice the difference from hS1 to hS1C34M5? Quite an improvement. I
don't know the rolloff parameter, do.

Any one knows you we can get rolloff?

BTW, a very complete set of files with satellites transponder list is
available at

>> http://joshyfun.cjb.net/ <<.

I recommend it's use. Thanks Joshy for providing such great files.

Testing continues.

And thanks Alex, for a great tool. The first one I used with
satisfactory results on DVB-S2 transponders. Well done.

Try adding "-k 3" to the command line, it should solve your random scan
problems.

Re: [linux-dvb] [ANNOUNCE] scan-s2 is available, please test

I don't know if anyone mentioned it already, but scan-s2 does not work for DVB-T.

Here is a patch which fixes DVB-T support.

Thanks Hans,

I have only TwinHan 1041 card (DVB-S/S2 stb0899 based), so could not test
anything else.

I will include your fix as soon as I'll get to work on it.

Will post a message with changes after that.

Some more updates for scan-s2:
- Fixed skip count specified by "-k" option (skipped one message less than
specified).
- Removed dumping (null) provider name.
- Fixed DVB-T tuning. Thanks to Hans Werner.
- Fixed some network ID output problems. Thanks to Oleg Roitburd.
- Added options to specify "S1" and "S2" entries in frequency file that will
use DVB-S and DVB-S2 scan modes respectively.
- Added "-D" option to disable scanning of some modes. "-D S1" will disable
DVB-S scan, "-D S2" will disable DVB-S2 scan.
- Added 3/5 and 9/10 FEC options. Thanks to Michael Verbraak.

In my TODO list so far:
- Revise and add diseqc motor support patch from Hans Werner.
- Revise and add few more patches sent by different people.
- Revise NIT message parsing to figure out why it doesn't add transponders
with correct delivery system.
- Add UTF-8 channels encoding support.

Please test the latest version of scan-s2 from:
http://mercurial.intuxication.org/hg/scan-s2/

Let me know if something doesn't work as it should.

Thanks.
Alex.

Hi

Sorry for a stupid question but as also the dv-apps version of scan and 
szap seems to work with S2API due to api's backward compatibility,
is the finding and locking of of S2 channels the "new" 
features that are visible for the end users?

I mean is the output of scan and scan-2 commands for example the same?

Mika

[-- Attachment #1.1: Type: text/plain, Size: 1257 bytes --]

I'm not aware of dvb-apps that use S2API, can you point me to that version?

S2 channels are found with old scan version using mantis driver as well.
The output of scan-s2 is a bit different to support S2, there are few more
parameters that will appear in the output such as:
Sx - used delivery system
Mx - modulation
Rx - rolloff
Cx - FEC rate

Some of those are not yet ready, but I'm adding them right now.
The frequencies files will be also extended to support those parameters as
inputs.

scan-s2 I've posted also includes uncommitted diseqc support that allows to
work with more than 4 LNBs.

I meant that because S2API drivers are backward compatible and supports 
also the older driver API, the old apps works also with S2API version of 
drivers.

Ok. Do you have time to add to README some words listing the 
names and order for all parameters that scan-s2 requires to be in the 
input files. That would be very helpful, when one later try to add 
information from other satellite frequencies to those files.

Ok. I didn't know that.

Alex,

Tested your scan-s2 with a Technisat HD2 card.

Scanning works. But some channels are reported twice with different 
frequency. I found an error which is fixed by the patch file named 
scan.c.diff1.

I would also like to propose the following change (see file scan.c.diff2 
or scan.c.diff which includes both patches). This change makes it 
possible to only scan for DVB-S channels or DVB-S2 channels or both. 
This is done by specifying lines starting with S or S2 in the input file.

example input file:
# Astra 19.2E SDT info service transponder
# freq pol sr fec
S 12522000 H 22000000 2/3       <only DVB-S channels are scanned>
S 11914000 H 27500000 AUTO
S 10743750 H 22000000 5/6
S 12187500 H 27500000 3/4
S 12343500 H 27500000 3/4
S 12515250 H 22000000 5/6
S 12574250 H 22000000 5/6
S2 12522000 H 22000000 AUTO    <only DVB-S2 channels are scanned>
S2 11914000 H 27500000 AUTO

I hope this is usefull.

Regards,

Michel.

Приветствую, Michel

but cx24116 based cards don't work with fec=auto for dvb-s2 

I'm not sure - may be for cx24116 cards the parameters roll off & modulation are obligatory (not optional)

Goga,

AUTO fec does work because the following is the result for the DVB-S2 
channels I get with the above input:

PREMIERE HD:11914:h:0:27500:767:772:129:6
DISCOVERY HD:11914:h:0:27500:1023:1027:130:6
ASTRA HD+:11914:h:0:27500:1279:1283:131:6
ANIXE HD:11914:h:0:27500:1535:1539:132:6

Regards,

Michel.

you have stb0899 based card, but I have mean cx24116 based card.

Goga,

Sorry I mis understood you. I used AUTO fec because the DVB-S2 channel 
on Astra 19.2 and frequency 11914 use FEC 9/10 according to the webpage 
kingofsat (http://nl.kingofsat.net/pos-19.2E.php). Because current 
scan-s2 does not handle this I changed it to AUTO.

fec table according to scan.c
struct strtab fectab[] = {
        { "NONE", FEC_NONE },
        { "1/2",  FEC_1_2 },
        { "2/3",  FEC_2_3 },
        { "3/4",  FEC_3_4 },
        { "4/5",  FEC_4_5 },
        { "5/6",  FEC_5_6 },
        { "6/7",  FEC_6_7 },
        { "7/8",  FEC_7_8 },
        { "8/9",  FEC_8_9 },
        { "AUTO", FEC_AUTO },
        { NULL, 0 }
};

New DVB API can handle FEC 9/10 (include/linux/dvb/frontend.h)
typedef enum fe_code_rate {
        FEC_NONE = 0,
        FEC_1_2,
        FEC_2_3,
        FEC_3_4,
        FEC_4_5,
        FEC_5_6,
        FEC_6_7,
        FEC_7_8,
        FEC_8_9,
        FEC_AUTO,
        FEC_3_5,
        FEC_9_10,
} fe_code_rate_t;

Will create a patch for this as soon as possible.

Regards

Michel.

Hi.
For me is also working strange scanning 30W Meo provider >>
http://pt.kingofsat.net/pack-meo.php
As you can see from the link above, all channels are on DVB-S2 8PSK
and sometimes scan picks up every channel and other times it doesn't.

After a few tries, every channel was picked up, but some parameters are missing.

This is a scanned channel list.
(null) - [000-0065];:12012:hS1:30W:30000:4097:4098:4100:100:101:0:0:0

As you can see, no network and provider are known, along with other
parameters, aldo I scanned with

./scan-s2 -O 30W -x -2 -t 1 -p -o vdr -s3 -v -U HispaOnlyMEO > Meo_3_test

I have tried with FEC 3/4

# 30W
S 12012000 H 30000000 3/4
S 12052000 H 30000000 3/4
S 12092000 H 30000000 3/4

and FEC AUTO

# 30W
S 12012000 H 30000000 AUTO
S 12052000 H 30000000 AUTO
S 12092000 H 30000000 AUTO

Auto seems to work better.

If anyone wants to give it a try, go ahead and leave feedback.

Using a TT-3200 on ubuntu 64.

Hello Michel,

Thanks for your proposals.

I also has a thought about S2 parameter in frequency file, but decided to
perform both DVB-S and DVB-S2 scans automatically since it easy on
maintaining the frequency file.

I will probably leave "S" frequency as is and will add "S1" and "S2" if you
want to specify what delivery should be used.
Also, I've been reported that some drivers can't work with AUTO modulation
so it have to be implicitly specified. scan-s2 will have to monitor the
modulation and scan S2 channels directly when 8PSK is specified or scan only
DVB-S if QPSK is specified.
