Force DVB-T instead of DVB-C who is by default on a DD Cine CT2 V7

Added by mk mkm about 10 years ago

Hi,

I'm trying to setup a card from Digital Devices DD Cine CT2 V7 - Twin Tuner Card DVB-C/T/T2 (PCI Express Card)

http://shop.digital-devices.de/epages/62357162.sf/en_GB/?ViewObjectPath=%2FShops%2F62357162%2FCategories%2FDownloadsNew1%2FLinux_Unterstuetzung_fuer_Digital_Devices_Produkte

Everything ok for the card who is now adapter 1 and 2. (adapter0 is a DVB-S card who work great)
drwxr-xr-x 2 root root 120 août 16 13:04 adapter0/
drwxr-xr-x 2 root root 120 août 16 13:04 adapter1/
drwxr-xr-x 2 root root 120 août 16 13:04 adapter2/

I've installed tvheadend but the card is recognised as a DVB-C, how can i make tvheadend change to be recognise at DVB-T ?

Below is the config file in tvheadend:

Best regards

RE: Force DVB-T instead of DVB-C who is by default on a DD Cine CT2 V7 - Added by mk mkm about 10 years ago

Hi Again

I've managed to make my card recognised in tvheadend as a DVB-T card and not as a DVB-C card by using the following command:

sudo w_scan -ft -c FR >> /home/mk/channels.conf

Unlike tvheadend, w_scan force a scan on the card using the DVB-T mode and the cart is set on the DVB-T mode until the computer restart.

But my problem now is any time my system restart, i need to run a scan on the both tuner of this card to make it usable with tvheadend.

Does anyone has an idea / solution ?

Best regards

You can try to set the mode using dvb-fe-tool. I put following into my tvheadend init script to force DVB-C:

/usr/bin/dvb-fe-tool --adapter=0 --frontend=0 --set-delsys=DVBC/ANNEX_A

Howeve in the current releases of tvheadend I can explicitly configure the DVB-C receive.

I have the same problem with my Terratec H5 tuner card. I want to use the DVB-T tuner, but tvheadend only uses the DVB-C. I can do a w_scan and it finds all the muxes it should. But when i start tvheadend it recognizes the adapter, but only as DVB-C tuner. When i change the config of the adapter in tvheadend/input/linuxdvb/adapters from DVB-C to DVB-T, i can add a dvb-t network to the adapter, but it still wont find any muxes. If i add them manually, tvheadend starts scanning and shows fail. Even if i do a restart, scan with w_scan, then start tvheadend it doesnt recognize my usb-adapter as dvb-t tuner. Seems to be dvb-c only in tvheadend.
I hope someone is able to help me.
Edit: I am using tvheadend version 4.1.289, but for the last 3 weeks i tried older ones, too. Without success...

My config is:

Thanks for your help!

I suggest you try dvb-fe-tool as Sebastian suggests. I use it as well to run my tv stick in DVB-C mode, with this command: dvb-fe-tool -d dvb-c, just add it to your rc.local script and it'll switch to the correct mode on start up.

RE: Force DVB-T instead of DVB-C who is by default on a DD Cine CT2 V7 - Added by Sebastian Brings over 9 years ago

dvb-fe-tool is an option. But I think that for quite a while now the receivers which support DVB-C and DVB-T alternatively are recognized and appear with two configurable inputs in tvheadend. At least this is true for my PCTV-520 and the Technisat Cablestart Combo HD CI I use with v. 3.9.2376 of tvheadend.
