Hello Dmitry, I am pleased that I was able to help you! But there is one thing that caught my interest, so I am againposting this question to the -dvb mailing list, and I guessto 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 defaultof `dvbstream' here is to use FFT transmission mode 2k, aswas introduced in the UK, and it's clear how UK-centric thisutility is based on the above line. (UK not meaning UA orUkraine) Now as part of DSO in the UK, the multiplexes are slowly toconvert from 2k to 8k, and most other parts of the world arepresently using 8k. In fact, as I `grep' the latest dvb-apps scan files, only theUK 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 thiscode, to make it applicable to the parts of the UK that haveswitched as well as most of the rest of the world? Reading the CVS RCS files, this doesn't seem to have beenupdated for several years, and presumably distributed binarypackages are using the UK defaults, the code of which seemsunchanged 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 toyour country, with the closest being in Košice, SK, I prefer tothink that we are in the same part of the world, with muchin common... > with best regards, Dmitry> Odessa, Ukraine Now, back to the original subject of this message, a scanfilefor Kиïв, with proper modulation values... Can you run the following commands for me, then send me thefiles in /tmp/stream-* so that I can verify the modulation? These will record three seconds worth of the NIT data withthe modulation, into several small files in /tmp, for allthe 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 filesin /tmp/stream-*.ts, and I will look at them, make surethat all the data in the scanfile is correct, and confirmit to Christoph Pfister... thanks,barry bouwsma _______________________________________________linux-dvb users mailing listFor V4L/DVB development, please use instead linux-media@xxxxxxxxxxxxxxxxxxxxxxxx@linuxtv.orghttp://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
