TV zenderlijst is pure DVB-T frequencies. I have not found a single FM frequency there. Note that if you open it via their website, there are two lists, FM zenderlijst and TV zenderlijst. > > After I have completed the scan (I leave in the Netherlands in Delft > area) I have not found few TV stations.

You are probably using an old scan file. I pushed an updated version a week or two ago. I'm still working on an automated way to have daily frequency releases, but even then it can take a while before packagers pick it up. Until then, you are free to use: http://git.linuxtv.org/dtv-scan-tables.git/blob_plain/HEAD:/dvb-t/nl-All As for your patch, I think it's wrong. On 522 Mhz (through the country, Delft as well) we have NTS4 (Bouquet 5) which is on a 2/3 coding rate, in your patch it's at 1/2. On 698 MHz we have NTS1 (Bouquet 2) which is on a code rate of 1/2. Feel free to correct me if I'm wrong. > > Thanks. > > Additional links: > > http://dvbt4all.nl/digitenne/zenders/zuid-holland-noord/delft/ > http://nl.wikipedia.org/wiki/DVB-T-frequenties > -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Thanks for updating the nl-All file. What will be the dvb-apps future version which will include the fix? Also what is the relation between git repo you've referred and this repo: http://linuxtv.org/hg/dvb-apps/log/f3a70b206f0f/util/scan/dvb-t/nl-All ? > As for your patch, I think it's wrong. On 522 Mhz (through the country, > Delft as well) we have NTS4 (Bouquet 5) which is on a 2/3 coding rate, > in your patch it's at 1/2. You're absolutely correct. Perhaps that is the reason why I cannot watch TV on 522 MHz. > On 698 MHz we have NTS1 (Bouquet 2) which is on a code rate of 1/2. Still I cannot make them working. More exactly: This works (722 MHz): xine "dvb://Nederland 1" xine "dvb://Nederland 2" xine "dvb://Nederland 3" These do not (522 MHz and 698 MHz): xine "dvb://Nickelodeon" xine "dvb://RTL 4" ... It can be the case the signal is better on 722 MHz... Could you share your channels.conf? Are there any specific options you pass to scan utility? But it's likely I need to buy better antenna. Can scan utility show the signal level? Thanks.

We've split the dvb-tables from dvb-apps, so never :p I'll work in the next few weeks on having 'releases' when there are changes so that package maintainers can start picking it up. > > Also what is the relation between git repo you've referred and this repo: > http://linuxtv.org/hg/dvb-apps/log/f3a70b206f0f/util/scan/dvb-t/nl-All > ? > >> As for your patch, I think it's wrong.

I don't 522 or 698 MHz, RTL4 is on 768 MHz here in Eindhoven. Try scanning with w_scan; wscan tells you exactly where what exactly is. It can produce an inital scanning file. Send me and I'll fix it up for you. > > It can be the case the signal is better on 722 MHz... Could you share > your channels.conf? Are there any specific options you pass to scan > utility?

Your ber isn't great but you have unc's UNC = Unrecoverable Error. This can usually be seen on screen or heard. unc should be 0 for 'perfect' image. So it looks like a bad signal reception to me, which could be the reason you are not receiving everything. > > $ tzap -c channels.conf "Nederland 1" > using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' > reading channels from file 'channels.conf' > tuning to 722000000 Hz > video pid 0x1b63, audio pid 0x1b64 > status 0f | signal 8f7d | snr 006e | ber 001fffff | unc 0000010a | > status 1f | signal 8e9f | snr 007b | ber 000a5010 | unc 0000000c | > FE_HAS_LOCK > status 1f | signal 8e2e | snr 0078 | ber 00084ed0 | unc 00000005 | > FE_HAS_LOCK > >> Signal is indeed important, Remember that RTL4 etc are all encrypted >> and need a hardware cam or softcam (oscam) to properly work. > Now I see!
