(and the DVB-T works too) this T-DMB stuff is still based on Transport Stream: http://en.wikipedia.org/wiki/Digital_Multimedia_Broadcast as i'd like to dump a full TS of the stream, i was thinking that it was just setting the proper mode (2) in the sms1xxx module, i would have been able to use the same "dvb-tools" like dvbstream to tune the right frequency and dump the whole TS. too easy, it seems! there were my steps: 1. i put the firmware file for T-DMB demodulation with the right name "tdmb_stellar_usb.inp" in /lib/firmware 2. i loaded the module with the supposed right default mode: modprobe sms1xxx default_mode=2 3. i put my stick on the linux, but the module didn't got up with this error: "SMS Device mode is not set for DVB operation." I'm halted. The showstopper come from this smsdvb.c where there's this control: ==================== if (smscore_get_devicke_mode(coredev) != 4) { #if 1 /* new siano drop (1.2.17) does this -- yuck */ sms_err("SMS Device mode is not set for " "DVB operation."); return 0; #else ==================== of course, this seems only a safety check. let's hope it's not just a "marketing" showstopper (i'm going anyway to try to relax this control, i bet i'm not going to burn anything inside the device!) probably there's more to be implemented to driver correctly the Siano chip when not in DVB mode. but how much? ask here could be useful.. it should be easy to "implement" the T-DMB stuff inside the same DVB scenario! it's already a system based on transport stream. right? sadly there are no open specs about it on the siano web site, just this brief: http://www.*siano-ms*.com/*pdf*s/00_Siano_SMS*1010*.*pd*f does anyone know a solution about this issue? is it so though to implement T-DMB decoding inside the DVB architecture? are the specs available somewhere? bye andrea venturi --------------050708050702050905050503 Content-Type: text/x-vcard; charset=utf-8; name="a_venturi.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="a_venturi.vcf" begin:vcard fn:Andrea Venturi n:;Andrea Venturi org:Avalpa Digital Engineering SRL adr;dom:;;Via dell'Arcoveggio 49/5;Bologna;BO;40129 email;internet:a.venturi@avalpa.com title:CEO tel;work:+39 0514187531 tel;cell:+39 3477142994 url:www.avalpa.com version:2.1 end:vcard --------------050708050702050905050503 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb --------------050708050702050905050503--
