New blind scan for DVB-C/T
« am: Mai 11, 2015, 07:53:18 Vormittag »
My name on openPli forum Dimitrij.
I want to add to the PLi image of the blind scan for sundtek tuners.
Show me examples of these command:
DVB-C  mediaclient --?
DVB-T  mediaclient --?

P.S.
mr. Sundtek my order 'Order No. 9692' for shop.sundtek.com
What do I do next?

Hi,

first of all the device needs to be set up into DVB-C or DVB-T/T2 mode - this is usually done with the sundtek control center.

Second of it the Blindscan feature is currently the same for DVB-C and DVB-T (because the DVB-T options are currently not exposed to the user).

DVB-T/T2 officially does not support hardware based Blindscan with the new devices, the devices are just able to scan DVB-T/T2 very fast so there's no noticeable difference but T/T2 would need some information eg. start frequency, stop frequency, frequency step at the moment we set up default values for Germany.
I think those values should be adjustable via the Controlcenter within the next updates.

Regular blindscan on the console, on any linux system:
/opt/bin/mediaclient --blindscan /dev/dvb/adapter0/frontend0

or in case of settopboxes
/opt/bin/mediaclient --blindscan NIMSOCKETNUMBER

Great idea.

create a blind scan for the DVB-S2 tuners(Sundtek SkyTV Ultimate)
and add this options for scan Controlcenter.

Since we updated our driver framework to support Blindscan in general it's all no problem now.

We'll update the drivers to support Blindscan for DVB-S/S2 once the new devices are available, I think it should even be possible to add Blindscan support for all our DVB-S/S2 products.

Thank you very much to order :)

And the question:
Three possible settings tuners add /etc/sundtek.conf?
If yes i will add the setting for the third tuner in SCC.

initial_dvb_mode you mean? The Sundtek Controlcenter supports all that already.

No.
Now it supports only two usb stick simultaneously.
Add support third stick for Sundtek Controlcenter.

Ah, yes.

The number of tuners supported should be limited by the number of vtuner interfaces in /dev/misc

And the number of tuners available can be figured out by running /opt/bin/mediaclient -e

This DVB-T frequency.
What is the answer scanning DVB-T2?
2)What is the third value(0)?

Our driver operates with virtual nodes, it does not need to register them for real.

Since you're trying to integrate it into e2 I think it might be better to contact us via skype (sundtek) or chat http://chat.sundtek.de

I only care about one issue.
How does the scanning DVB-T2?
There is a value PLP ID?
