Hello.

I think I came across a bug in either of the drivers si2168 and dvbsky
regarding
blind-scanning DVB-T2-frequencies.

HW: Technotrend CT2-4400v2 (afaik based on or the same as DVBSky T330)
     demod: Si2168-B40
     tuner: Si2158-A20
OS: Ubuntu 15.04 (kernel 3.19)

In Austria, the DVB-T2-service "SimpliTV" is currently airing up to four
muxes, next to one or two DVB-T-muxes.
In my region, the frequencies are 490MHz, 546MHz, 690MHz, 714MHz for
DVB-T2,
and 498MHz for DVB-T.
These numbers might be of interest when reading the logs.

The peculiar aspect of these T2-muxes is that they're aired on PLP 1
without
there being a PLP 0. I think this is also the root of my problem.

dvbv5-scan is working, but w_scan not?

Could you hack si2168.c file and test?

if (c->delivery_system == SYS_DVBT2) {
    /* select PLP */
    cmd.args[0] = 0x52;
    cmd.args[1] = c->stream_id & 0xff;
//    cmd.args[2] = c->stream_id == NO_STREAM_ID_FILTER ? 0 : 1;
    cmd.args[2] = 0;
    cmd.wlen = 3;
    cmd.rlen = 1;
    ret = si2168_cmd_execute(client, &cmd);
    if (ret)
        goto err;
}

The scan only finds one of the four transponders (714MHz), but it doesn't end up in the tuning-file.
The other three are tuned, but not locked.

When doing a blind-scan using w_scan 20140727 on Ubuntu 15.04 (kernel
3.19),
w_scan does not find any of these four DVB-T2-muxes.
It just finds the DVB-T-mux.

Logs:
media-tree_dmesg_lsusb.txt http://pastebin.com/0ixFPMSA
media-tree_w_scan.txt http://pastebin.com/yyG3jSwj

The found transponder:
initial_v3_media_build_trunk.conf http://pastebin.com/LmFQavpy
initial_v5.conf http://pastebin.com/Jx6kymVt

I also tried a fresh checkout from git.linuxtv.org as of last weekend
and the
most recent w_scan version (20141122).

As you can see, w_scan tries to tune(?) the DVB-T2-frequencies, but
ultimately doesn't find anything on them.


Then I tried the DVBSky-linux-driver[1]
(media_build-bst-20150322.tar.gz)[2]
from their site, which is using a binary called sit2 for this card.
Using this driver, w_scan found all four DVB-T2-muxes and the DVB-T-mux.
Additionally, it found the DVB-T2-muxes during the DVB-T-scan.

Logs:
media_build-bst_dmesg_lsusb.txt http://pastebin.com/vJeDMxtu
media_build-bst_w_scan.txt http://pastebin.com/yhwAYjen

Found transponders:
initial_v3_bst.conf http://pastebin.com/ECKQvRWX
initial_v5_bst.conf http://pastebin.com/CbhY6Hpz

Of course, doing a channel-scan using dvbv5-scan on these transponders
worked
too:

dvbv5_sit2.conf http://pastebin.com/3W52bbhv
dvbv5_sit2.log http://pastebin.com/nc66PTkt

Afterwards, I tried to do a channel-scan with the same initial tuning-file
using the opensource-driver, which also worked:

dvbv5_si2168.conf http://pastebin.com/A6FbqUL1
dvbv5_si2168.log http://pastebin.com/ewyVPJR2

This should verify that tuning PLP 1 without there being PLP 0 is not
the issue.


Additionally, if you compare the two channel-lists, you find interesting
differences:

The scan with si2168 has AUTO for "MODULATION" and "INVERSION" for
DVB-T2-channels, and for "CODE_RATE_LP" and "INVERSION" for DVB-T-channels.

The scan with sit2 has the respective values in the channel-list.

The dvbv5-scan-logs also differ, as using sit2 also displays the signal
quality
during tuning.


I know that there were changes regarding DVB-T2-scanning[3], but as the
blog-
article specifically mentions si2168 and w_scan to be fully dvbv5-compliant
and good for using with DVB-T2, I thought you should know about this
particular problem.


In the attachment I've packed the previously linked logs, for archival
reasons.


Thank you for your attention.
