Hello Dmitry, I am pleased that I was able to help you! But there is one thing that caught my interest, so I am again posting this question to the -dvb mailing list, and I guess to linux-media too: On Fri, 16 Jan 2009, vdp wrote: > But when I add -tm8 (THANK YOU FOR AUDIT !!!!): > it start !!!! > dvbstream -tm 8 -c 0 -I 2 -qam 64 -gi 32 -cr 2_3 -bw 8 -f 650000000 -net 224.12.12.12:1234 4311 4312 > tuning DVB-T (in United Kingdom) to 650000000 Hz, Bandwidth: 8 To the readers of the list, and of linux-media, the default of `dvbstream' here is to use FFT transmission mode 2k, as was introduced in the UK, and it's clear how UK-centric this utility is based on the above line. (UK not meaning UA or Ukraine) Now as part of DSO in the UK, the multiplexes are slowly to convert from 2k to 8k, and most other parts of the world are presently using 8k. In fact, as I `grep' the latest dvb-apps scan files, only the UK sites listed seem to be using 2k, for now. Does anyone familiar with DVB-T know whether 2k transmission mode is used elsewhere in the world? If not, would it not be reasonable to default to 8k for this code, to make it applicable to the parts of the UK that have switched as well as most of the rest of the world? Reading the CVS RCS files, this doesn't seem to have been updated for several years, and presumably distributed binary packages are using the UK defaults, the code of which seems unchanged from 2002, so I imagine this could use reworking. > wonderful word !!! You, from other country help me, real-time and free !!!! It is indeed my pleasure. While I have not made a visit to your country, with the closest being in Košice, SK, I prefer to think that we are in the same part of the world, with much in common... > with best regards, Dmitry > Odessa, Ukraine Now, back to the original subject of this message, a scanfile for Kиïв, with proper modulation values... Can you run the following commands for me, then send me the files in /tmp/stream-* so that I can verify the modulation? These will record three seconds worth of the NIT data with the modulation, into several small files in /tmp, for all the different multiplexes. First, the command you used above to stream 5 ĸaнaл : dvbstream -tm 8 -c 0 -I 2 -qam 64 -gi 32 -cr 2_3 -bw 8 \ -f 650000000 -o:/tmp/stream-650.ts -n 3 16 Now try it with the other frequencies and see if you still can lock: dvbstream -tm 8 -c 0 -I 2 -qam 64 -gi 32 -cr 3_4 -bw 8 \ -f 634000000 -o:/tmp/stream-634.ts -n 3 16 dvbstream -tm 8 -c 0 -I 2 -qam 64 -gi 32 -cr 2_3 -bw 8 \ -f 714000000 -o:/tmp/stream-714.ts -n 3 16 dvbstream -tm 8 -c 0 -I 2 -qam 64 -gi 32 -cr 2_3 -bw 8 \ -f 818000000 -o:/tmp/stream-818.ts -n 3 16 And last, a frequency where the services are in MPEG-4: dvbstream -tm 8 -c 0 -I 2 -qam 64 -gi 32 -cr 2_3 -bw 8 \ -f 682000000 -o:/tmp/stream-682.ts -n 3 16 If you have success, then you can send me all the files in /tmp/stream-*.ts, and I will look at them, make sure that all the data in the scanfile is correct, and confirm it to Christoph Pfister... thanks, barry bouwsma -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
