Currently, there is a small confusion. Most drivers in kernel, just report some crap as signal strength, snr etc. For the STB0899, STM helped so much, alongwith i had some help from one of the Newtec guys, we were able to get the statistics in some proper form, currently a dBm/10 scale is used. Since this scale is different from the in kernel existing scale of randomness to a standardized one, currently this change might look a bit nonsense to you as it will report different signal statistics as reported by the API. There will be a need to add one more ioctl, where the user can request the driver to provide the statistics in a relative scale or an absolute scale which can be used for measurements too. The result would be that and end application can display the statistics like any other commercial STB, in a nice and beautiful way, while being quite accurate (depending on the driver) without any hacks or workarounds to be \ done in the application (The statistics that you get is very much device specific and not device independant and hence is not very easy for a user application to get proper statistics as of now) With the change, all statistics related operations can be implemented within the driver such that the user is presented with standard and uniform statistics across multiple devices without the need to do device specific code as done by MythTV etc, where it looks for specific device drivers (really ugly) > The rotor plugin doesnt return anything and I can't get anything out > of VDR-Femon. > > Is it working OK with the TT 3200? The statistics is working with the STB0899, maybe i didn't follow what exactly you are looking at. If you can detail a bit, it would be much more helpful. The STB0899 supports TT S2 3200, KNC1 DVB-S2+, KNC1 DVB-S2, Pinnacle PCTV 450e and the VP-1041 as of now and the same signal related stuff is applicable to all. > BTW I have a TT3200 on order so I can compare the difference between > the two cards soon. Currently, the STB0899 is _not_ calibrated for actual statistics. I have requested Azurewave for some sample devices to be sent to STM for proper calibration of the LUT's for the statistics. (Most probably, tomorrow or so STM will receive the samples at Grenoble) Regards, Manu _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
