Description

There are two kind of models. Both models are external USB 2 DVB-T receivers for terrestrial digital transmissions. They are external USB 2.0 sticks that will not work with 1.0 USB ports.

The newer model has an USB input on the front, an RF connector at the back, and an infrared receiver on the side. It is bus powered and does not come with a remote control.

The old model has at the back, a USB socket and an RF aerial connector, and come with a standard USB connector. In the front, it has an infrared receiver and a led that lights when pressing the remote control keys. It is bus powered and comes with a remote control.

Installation guide

Installation differs for the two kinds of models.

Old models

Get kernel sources above 2.6.12.rc3, I used mm-sources as my usual gentoo-sources doesn't run this close to the cutting edge.

Enable the "Di Bcom USB DVB-T devices" / CONFIG_DVB_DIBUSB kernel module. Make and install your new kernel and modules.

Get a copy of the firmware (on mine "dvb-dibusb-nova-t-1.fw") from either the dvb-kernel cvs (in firmware/, will need renaming from "dvb-usb-nova-t-usb2-01.fw") or here. Place this in either /lib/firmware/, or /usr/lib/hotplug/firmware/ (if you dont know which it is on yours, try one and the step below, if u get a cant find firmware error in dmesg, try the other).

New models

You need the firmware called 'dvb-usb-dib0700-01.fw'

The newest drivers available from the snapshot of 09/12/2006 from www.linuxtv.org[2] are needed, otherwise you will get the errors described here[3].

Having the newest stable kernel (2.6.19) does not alleviate this problem, you still have to compile&install the above mentioned sources. Possibly the 2.6.20 will have these drivers integrated (see mail from linuxtv maintainer to Linus).

Fedora Core 5 with newer models of the Nova

Assuming that dvb-usb-nova-t-usb2-01.fw (as above) doesn't work for you... My symptoms were... Detection and then firmware download seemed ok. On "hot" reboot of box it all locked up, on a "cold" reboot nothing much happened (the frontend wasn't found and the DVB devices not created). If you have similar problems you may need newer firmware. You need to find dvb-usb-nova-t-usb2-02.fw (not "-01"), I got it from http://www.thadathil.net/dvb/fw/ after spotting a posting on a forum. I then put it into /lib/firmware and renamed it to dvb-usb-nova-t-usb2-01.fw (for luck you could also put a symbolic link in /usr/lib/hotplug/firmware/ if you like but I didn't need to). Everything seemed to work ok after that.

Plug in the box. If you're using hotplug and udev, a new adapter should show up in /dev/dvb.

From there, it's just like testing and configuring other DVB cards.

Note: The thadathil.net website no longer exists, but a bunch of firmware (including dvb-usb-nova-t-usb2-02.fw ) is here http://ubuntuforums.org/showpost.php?p=4570186&postcount=6 --Jak 14:01, 23 March 2008 (UTC)

Issues and Problems

The kernel driver for this card suffers from long standing misbehaviours that prevent it to work with MythTV 0.19.

I've heard that there can be problems tuning sometimes, but MythTV from version 0.20 (I think) allows you to add a delay to when tuning to the card. You do this in the offline mythtv-setup program, go to the DVB card, then Recording Options and set a delay (I think the onscreen help even mentions this card). This solution "might"? be related to the above problem?

Associated Software

• tzap : Channel changer program
• scan : Tuner config scanner
• mplayer : good for testing that the tuning is working

The best method to get the tzap and scan programs is to build them from the cvs at linuxtv.org..

• w-scan, available from http://www.edafe.org/vdr/wscan.html, very easy to use

The Nova-t Remote Control

• Handset: This is the newer Hauppauge grey top / black underside unit. It takes a pair of AAA batteries and has 45 buttons.
• Receiver: The receiver for this card is a small round IR diode unit integrated in the case.

Setup

Newer kernels have support for this card as a keyboard. Button pushes received by the dongle are translated into keyboard events. Kernel 2.6.15 understands all the buttons, but only the arrows, OK, numbers and volume keys have functions assigned. One way around is to patch the drivers/media/dvb/dvb-usb/nova-t-usb2.c file to use standard keys instead of multimedia keys.

LIRC

You don't need to patch the kernel to detect which device the tuner has been assigned to.

Add the following to your lircd init script, assuming LIRCD_OPTS is the variable used to pass options to lircd. This greps the IR control activation string out of the kernel device message buffer, and passes the correct device number as an option. This trick works with pretty much any input device assigned a variable device ID at startup, as long as it logs a distinctive message.

DEVNUM=$(dmesg | grep "input: IR-receiver inside an USB DVB receiver" | egrep [0-9]{1}$ -o)
LIRCD_OPTS="-d /dev/input/event${DEVNUM}"

The file with the keycodes is not the same as with the PCI version, but is "/usr/src/linux/drivers/media/dvb/dibusb/dvb-dibusb-remote.c" (Scroll down to "/* Hauppauge NOVA-T USB2 keys */"). I tried adding these as new keybindings with MythWeb, but that did not work either.

To get it working I changed the keys in the above source file to match the (mostly) default mythtv keybindings. You can see my final version here. Not all the keys are doing anything useful at the moment, but at least it works!

Keyboard

Presumably you could leave out the LIRC support from MythTV and just map the keypresses that the remote uses to the features of Myth, but neither X.org nor Qt 3.3 knows about the extended multimedia keys.

An alternative approach

I have this working with FC5 plus SVN Myth...

I have lircd enabled in the compile of Myth. I installed lircd through yum. I'm experimenting with udev to see if I can get it to create a specific device for me for the Nova Remote (as the above rather neat and clever grepping only works for a while after reboot as dmesg is a circular buffer). Also, I had to specify the driver as dev/input for anything to work. In the meantime my /etc/sysconfig/lircd reads (I'm considering options ;) )...

# Options to lircd
#LIRCD_OPTIONS=
DEVNUM=$(dmesg | grep "input: IR-receiver inside an USB DVB receiver" | egrep [0-9]{1}$ -o)
# LIRCD_OPTS="-d /dev/input/event${DEVNUM}" 
LIRCD_OPTIONS="--device=/dev/input/event1 --driver=dev/input"
# LIRCD_OPTIONS="--device=/dev/input/event${DEVNUM} --driver=dev/input"

As the kernel understand "some" of the keys (and I don't want to compile kernels...), there can be problems when you want to use ALL of the keys as you can get a few double triggers (e.g. kernel plus keyboard emulation = two Ups I decided to use slightly less common names to avoid "double triggers" e.g. ArrowUp rather than Up. This seems to work ok, although I can't promise ALL the codes will work. If not, try making your own lircd.conf file with irrecord - but use the same "names" for the keys.

My lircd.conf file is as follows

Once you have this up and running (e.g. add the file and get lircd running ok) use irw to check that all is ok. e.g.

[root@mythtv mythtv_svn]# tail -f /var/log/messages | grep lirc &
[1] 6342
[root@mythtv mythtv_svn]# irw
Oct 17 23:07:51 mythtv lircd-0.8.1-CVS[2266]: accepted new client on /dev/lircd

[root@mythtv mythtv_svn]# fg
tail -f /var/log/messages | grep lirc
 
[root@mythtv mythtv_svn]# 

If lircd falls over (watch in syslog) when you start irw then you probably have the wrong input. I have then a lircrc file like this... (please note this is adapted and all the xine/mplayer stuff I haven't really finished yet... ) This is a work in progress so there may be things that don't work, or don't work the way you want. But it's a start heh? PS I use the Yellow and Blue for commercial skipping, and the top row of buttons for "Jumping" around in MythTV (these are defined towards the end of the MythTV stuff). After that it is mostly untouched from Jarods stuff. I'll update this once I've got xine the way I want it. I probably won't bother too much with mplayer stuff now.
