Enable Analog TV Card with Remote Control to Watch TV on Ubuntu

linux kernel has saa7134 module built-in. All you need is to load it.

1. create a module setting file for booting use

sudo vi /etc/modprobe.d/saa7134

# This setting is for LifeView FlyTV Prime 3X / FlyVIDEO3000
# you can find correct values from http://gentoo-wiki.com/HARDWARE_saa7134
options saa7134 card=2 tuner=50

2. in order to load saa7134 while booting, add the name of module into /etc/modules

sudo vi /etc/modules

saa7134

3. reboot to enable the above settings

# some useful commands for module
modprobe <name> # load module manually
lsmod # list all modules have been loaded
rmmod <name> # remove module manually

4. install tv software

sudo apt-get install tvtime

5. start tvtime from Application -> Sound & Video -> tvtime

6. control TV with arrow keys
↑ +channel
↓ -ch
→ +volume
← -vol

7. check if IR Receiver has been found

dmesg | grep IR

--
input: saa7134 IR (LifeView FlyVIDEO30 as /devices/pci0000:00/0000:00:1e.0/0000:01:00.0/input/input4

8. figure out what number of event is registered

cat /proc/bus/input/devices

--
I: Bus=0001 Vendor=5168 Product=0138 Version=0001
N: Name="saa7134 IR (LifeView FlyVIDEO30"
P: Phys=pci-0000:01:00.0/ir0
S: Sysfs=/devices/pci0000:00/0000:00:1e.0/0000:01:00.0/input/input4
U: Uniq=
H: Handlers=kbd event4
B: EV=100003
B: KEY=c0304 390000 0 0 0 0 0 0 c0000002 1e0000 0 0 10000ffc

9. install and configure lirc

sudo apt-get install lirc

--
choose Linux input layer (/dev/input/eventX) as remote
choose None as IR transmitter which is able to both send and receive
choose /dev/input/eventX as custom event interface

9. make sure lirc is running

sudo ps -ef | grep lirc

if not, start it

sudo /etc/init.d/lirc start

10. use irw command to check if the device does work

irw

--
# press any button on your remote control
0000000000010175 00 MODE linux-input-layer
0000000000010189 00 VIDEO linux-input-layer
0000000000010188 00 AUDIO linux-input-layer
.
.

11. then begin to record your own definition, follow the instructions on screen

sudo irrecord -H devinput -d /dev/input/event4 /etc/lirc/lircd.conf

commands support by tvtime-command, see http://tvtime.sourceforge.net/usage.html#tvtimecommand

13. irexec should be started before running tvtime, tvtime is signalled from lirc using this helper application. if we need it start after gnome login, go to

System -> Preference -> Sessions
Startup Programs -> Add
Name: irexec
Command: /usr/bin/irexec -d
