Dvb usb

[simulatorhck]

Per chi è piu pratico in programmazione e sistemi...Volendo utilizzare un tuner usb dvb-t quali moduli bisogna compilare?
Ho inserito dvb-core.ko e avvio manualmente con insmod ma poi non so cosa fare...
Esiste un'app che possa effettuare la scansione e visualizzazione dei canali posto che poi non serva un modulo driver o un driver aggiuntivo per il sintonizzatore?
Io ho un device 10fd 1506 e in ufficio una wintv nova...

Dvb-t? Sono i dib0700 ma poi ti serve un programma che si interfacci, su Linux anche mplayer lo fa

Infatti quello è il problema secondario...Ora devo ancora capire se e quale driver mettere su (e come ) per le perifieriche su menzionate...

Io ho una Win nova t stick collegate all'htpc e funziona perfettamente con i dib guarda su linuxtv.org per ulteriori info

Penso proverà anche questi dvbpkg_v0.8b2.zip - archos-gen8-dvb - release v0.8beta2 - DVB support for Archos Gen8 devices - Google Project Hosting

ciao a tutti
c'e' qualche anima pia che potrebbe spiegare un po' piu' dettagliatamente la procedura?
grazie

Allora...iniziando per gradi la prima cosa è capire quali sono le dipendenze da soddisfare...Possiedo una hauppage wintv nova-t stick usb2 e da dmesg mi da come identificativo

Ecco qui...penso che sia la lista dei moduli da utilizzare...
Making it Work (generic for all dib0700)
Firmware

August 21, 2008 - New firmware file fixing the last cause for i2c errors and disconnects and providing a new, more modular i2c request formatting.

You will need the dvb-usb-dib0700-1.20.fw firmware file in /lib/firmware or the relevant place for your distribution.

You may need to change the name of the file to dvb-usb-dib0700-1.10.fw or create a link until the driver code reflects that change.

For archival purposes: dvb-usb-dib0700-1.10.fw firmware file

August 29,2008 - Issues with Firmware 1.20. Some issues have been found with the latest version of the firmware. Users may wish to continue to use 1.10 unless they have patched their v4l-dvb code with dib0700_new_i2c_api.patch.

November 15,2008 - Issues with Firmware 1.20.

The above mentioned dib0700_new_12c_api.patch is not available discretely but is now rolled into the mercurial drivers
dvb-usb-dib0700-1.20.fw firmware file is now stable for reception, but remote control functionality is broken; any key press is repeated until the next key is pressed. The only way to get remote control functionality presently is to roll back to 1.10 firmware and suffer the occasional disconnect.
The mercurial drivers have been changed so they now load 1.20 firmware. To revert to 1.10 firmware you need to rename your firmware file to dvb-usb-dib0700-1.20.fw or provide a link of that name.
To avoid spurious remote control signals with 1.20 firmware, you need to edit /etc/modprobe.d/options or from Ubuntu onwards /etc/modprobe.d/options.confand add:

options dvb_usb disable-rc-polling=1

November 28,2008 - i2c errors. Changes were made to the remote control drivers on November 16,2008 to correct the repeat key problem. The card is generally stable for dual tuner reception and remote control function with Firmware 1.20.

November 10,2009 - mt2060 I2C write failed. Possible regression of a driver bug raised against Ubuntu running 2.6.27-14 and 2.6.31-2.17 causing mt2060 I2C errors in MythTV useage with firmware 1.20. https://bugs.launchpad.net/ubuntu/+s...ux/+bug/397696 Recommend check the kernel extensions listed here for Low Noise Activation and rc_polling are loaded with correct config file name for your distribution, EIT listings information is turned off until a suitable delay (500ms-1000ms)is added to a single card (not both) and the card has correctly been added to the database as two tuners (no additional NULL entries) in the mythtv recordcard table.
Drivers

It requires the dib0700 driver. Just use Mercurial by following the How to Obtain, Build and Install V4L-DVB Device Drivers instructions.
Forcing the activation of LNAs (Low Noise Amplifier)

You may have to force LNA to get this card working:

In /etc/modprobe.d/options add:

options dvb_usb_dib0700 force_lna_activation=1

Disabling the remote control sensor

You may want to disable the remote control sensor if you are using another one and want to avoid error messages in the logs:

In /etc/modprobe.d/options add:

options dvb_usb disable_rc_polling=1

All relevant kernel modules options

In /etc/modprobe.d/options add:

options [module name] [option name]=[setting]

Get the parameters list using

modinfo [name of kernel module]

ciao simulator
dopo il nostro scambio di mag privati sono andato un po' avanti...
ora la mia ignoranza in materia e' un pochino meno colma )
ho scoperto che la mia chiavetta, una terratec cinergy t stick al momento non e' supportata.
pare dalla 2.6.37 in poi...
quando vado a fare insmod del dvd-core.ko mi dice exec format error.
vuol dire che il kernel e' diverso giusto?

cmq ho trovato in rete un po' di guide, ti metto i link, magari ti possono essere utili.

esattamente...Sono compilati per altro kernel. Io posso darti alcuni moduli ma il discorso è che vanno abilitati in un certo ordine..Stasera se riesco cerchero di seguire quanto sopra.. Resta sempre il nodo del software che poi utilizzi il tutto...
