Blindscan on VU+ Solo2 with OpenPLI image

[v1c10u5]

Hello,

I recently purchased your your MediaTV Digital Home and managed to install it succesfully on my VU+ solo2 running the latest OpenPLI image.
Currently the only option to scan for channels is through the Manual scan.
The Automatic scan is giving me:"ERROR - failed to scan (error starting scanning)!".
Blindscan 1.4 and Fast scan are not recognizing the DVB-C tuner in the Tuner option inside the plugin. (I can only scan the built-in Tuner A and Tuner B).

Any ideas what i'm doing wrong or how can i get the blindscan plugin to recognize your usb tuner?

Thanks in advance,

[Sundtek]

Blindscan is not supported by external tuners at the moment, we will release an update within the next 1-2 Weeks which finally will add support for this.

For now you need to scan one frequency manually and enable the network scan. This should discover all Transponders in your network.
Please note even we add support for Blindscan in the near future this will only work with tuners from 2014 on (earlier versions do not have hardware support for that).

[v1c10u5]

Thank you for the fast and informative reply.

Do you by any chance know how i could check if my solo2 hardware supports blindscan or not?
And also do you have any idea why the Automatic scan is giving me an error message?

[Sundtek]

When did you buy the Tuner?

All tuners from 2014 support Blindscan.

[Sundtek]

Blindscan support is available with the latest driver update.

scaning sat 13e

Question what is the frequency?
The second column?

[Sundtek]

Is that Ku-Band? The frequency is usually the second column. The third column is the symbol rate.

[Dima73]

Yes Ku band 13E
In the second column the wrong digit.

Code: [Auswählen]

if freq < 4201000 and freq > 2999000 :
band = 'C'
self.is_c_band_scan = True
elif freq < 12751000 and freq > 10700000 :
band = 'Ku'

[Sundtek]

It depends how you scan, I see that the value is in the intermediate band 950-2150 MHz you need to re-calculate it by yourself.

/opt/bin/mediaclient --blindscan /dev/dvb/adapter1/frontend0 will retrieve the Ku-Band frequencies.

What does /opt/bin/mediaclient -e show up? I guess you have more than one tuner attached.
I guess you have used the wrong tuner. try adapter2 then possibly.

[Sundtek]

I think it is better to calculate it by yourself

Code: [Auswählen]

                                                if(strcasecmp(band, "C-BAND")==0) {
                                                        frequency = 5150000-feparm.frequency;
                                                } else if(strcasecmp(band, "UNIVERSAL")==0) {
                                                        if (tone == SEC_TONE_ON) {
                                                                frequency=feparm.frequency+10600000;
                                                        } else {
                                                                frequency=feparm.frequency+9750000;
                                                        }
                                                } else {


There's C-band and Ku-band

Low Band V = 13V No tone
Low Band H = 18V No tone
High Band V = 13V + 22khz tone
High Band H = 18V + 22khz tone

edit: copied the wrong code snippet, the current one shows you how to calculate the frequency

[Dima73]

Sorry, this is С++.
I need Python code.
C-BAND? where does this matter?

Code: [Auswählen]

OK 968531 27500 FEC_AUTO NOT_IMPLEMENTED INVERSION_OFF

Code: [Auswählen]

MODE: DVB-S  FREQUENCY(MHz): 10718 SYMBOL_RATE: 27500 MODULATION: QPSK VOLTAGE: 13V TONE: OFF
this is egual value.Only different formats.

is 968531 need 10718 why?

[Sundtek]

C-Band is used in America, we also have users in the United States and Canada who use Settopboxes.

For Ku-Band:
MODE: DVB-S  FREQUENCY(MHz): 10718 SYMBOL_RATE: 27500 MODULATION: QPSK VOLTAGE: 13V TONE: OFF

it says 10718 MHz
while
OK 968531 27500 FEC_AUTO NOT_IMPLEMENTED INVERSION_OFF
is in KHz

10718XXX KHz = 968531 KHz + 9750000 (=10718531) -- since tone is off you only need to add 9750000, if tone would be on you would need to add 10600000


It's about the calculation itself and that one should be clear (regardless of the programming language).

For C-Band you need to calculate it that way:
cband_frequency = 5150000-tuner_frequency;

the tuner_frequency is always between 950 - 2150 MHz (950.000 - 2150.000 KHz)

This is an example for a C-Band Satellite:
http://www.lyngsat.com/Telkom-1.html

see the frequency they are comparable low compared with the Ku-Band Satellites.
