Install TV Tuner Card in LINUX - Intex, Frontech and etc

Here I am going to explain how to install the TV Tuner Card which you purchased locally in your area i.e either Intex or Frontech TV tuner.

This page is usefull to the all Linux Lovers who want to use the TV Tuner in SUSE Linux, Redhat, Ubuntu and etc.,

I explained about how to identify the drivers for the local TV tuner Cards i.e there you have the cards such as Intex, Frontech, Typhoon, Asus, Avermedia, and Pinnacle etc.,

So almost all of the TV tuners are using the same chip inside them i.e Philips SAA713x chip. Also you can say that this article mainly focuses on SAA7130 TV tuner card Installation How To.

***Before doing all this you need to install two applications either bttv or tvtime then only you can see the output

Understanding the TV Tuner card -

Every TV Tuner Card is having two sections

1. Video Decoder
2. The Tuner

When you directly look at the PCI TV Tuner Card you will see the chip Philips SAA7130 Chip
You can also see sometimes i.e manufacturer puts a Sticker on the tuner, so remove that and see what is there on the chip. or you can go for the Windows Driver CD and check the model number.

To determine use the following Linux commands at prompt using sudo or root login

lspci <- Command

dmesg <- Command

when i enter the command lspci you will see the output such as (may different in your system)

00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 01)

Loadable Kernel Module Saa7134

LKM (Loadable Kernel Modules) for SAA713x chips (SAA7130, SAA7133, SAA7134 etc.,) this module name is saa7134.

Also sometimes we need the dependancy modules like saa7134_alsa, saa7134_dvb, tuner and etc.,

Actually nowadays all of the Latest Linux operating systems have the drivers inside including modules. When you first started the computer with the TV tuner it will load the module into it just you need to verify and configure most of the times.

If you really want to start freshly do the following

rmmod saa7134_alsa saa7134_dvb saa7134

the above command will remove the 3 modules saa7134_alsa, saa7134_dvb, saa7134.

Loading the module is using the following command with the parameters and card, tuner

before using the modprobe command you can also know the information of that module using the command such as

modinfo saa7134

also try -p -d switches

Here i want to concentrate on what to use for the card parameter i.e 3 value is supporting most of the TV Tuner cards.

so you will get good results on using

modprobe saa7134 card=3

In some Linux flavours use the following settings instead of loading the module on every restart of the system

i.e

open the modeprobe.conf file and put the line

modeprobe saa7134

-------------

for the card parameter you can also try the good values i.e percent of getting worked is high is this 3, 10, 21, 42 etc.,

otherwise try the command with all the values and decide where you got the result at last.

for more information what is there in kernel viosit the following link

http://linux.sourcearchive.com/documentation/2.6.27-9.18/saa7134-cards_8c-source.html


new versions of kernels adds more and more cards to this list.


Loading the Tuner

The driver saa7134 is written such a way that each card is associated tuner spec. i.e default tuner for each card no need to override.

You no need to load the tuner once you setup the card correctly.

if at all you need to override the tuner use the following command.

modprobe saa7134 card=3 tuner=37
or
modprobe saa7134 card=3 tuner=55

some times also use the parameter such as gbuffers=4 along with the above command


Once you have done this connect the cable to the tv tuner and scan for channels

by using the command

tvtime-scanner

all the channels will be scanned and stored in the file called stationlist.xml

after this use the command to see the tv

tvtime

you will see the gui windows where you will see the output also you can see the menu to get the scanning channels and settings

Trouble shooting


Many of the times you will not hear the sound from the tvtuner for that check the back side to put the cables at correct position i.e put the tv tuner card audio out to the sound cards line in. the chip saa7130 will not do any audio processing like others.

Also check the sound mixer in the system i.e it is not muted or too low voice .


-------------------------------

In short i will give you small

dmesg
lspci
sudo rmmod saa7134_alsa
sudo rmmod saa7134
sudo modprobe saa7134 card=3

in tvtime i selected the following values

our system- PAL or PAL B/G (Countries like India)

Country - Europe (for compatibility with India as there is no option for this)

to load the tvtime or bttv in Opensuse 11.1 i use the following command

sudo zypper install bttv
sudo zypper install tvtime


Thanks to all and enjoy. Give your valuable suggestion and feedback

Change the Network Settings for Internet or Intranet

Really you want to change the Network settings on your own then here is the solution, follow the below instructions.

Whenever you are configuring the network you have to provide following two things

i.e

the first one is IPADDRESS (192.168.1.2) by which the system will recognize it in a network and the second one is the SUBNETMASK (255.255.255.0) which will give you the information i.e how many network devices can be there in the network

To give your desired IPADDRESS then that will be called as STATIC IP, Otherwise the server or network switch in your network will provide the IPADDRESS of its own configured is called as DYNAMIC and i.e with the DHCP server.

OK to specify the static IP, follow the below mentioed steps

Open the terminal and issue the following commands at prompt

#neat

then you will see network setting window, the select the proper network interface i.e "eth0" Ethernet

and click on edit

check the option Statistically set IP addresses and give the values and save the settings.

and reboot the laptop, enjoy now you are done

E-Courts Login screen showing "User Judge home directory" is not mounting

When the Laptop boots correctly and you get the Login screen and when you are trying to enter into the

judge

username and password it will show you the error that "user judge home directory"

So, what is the reason for this, hey the problem is with the LUKS passphrase i.e entered incorrectly for 3 consecutive times when the system restarts or boots.

Then what to do with this error!

Here is the solution, you know that it happened due to the LUKS passphrase then reset it.

for that http://jailinux.blogspot.com/2009/02/luks-password-asking-three-times-on-e.html

follow the link

or see below
*******************************
(Linux Unified Key Setup or LUKS is a disk encryption specification)

Reset LUKS passphrase by login as "root" and the password is "redhat"

Once you loged into the "root" user open the terminal and issue the following command

i.e chng_passphrase

then the system will prompt you for the new passphrase. enter the passphrase of your choice or use the default one i.e "courts"

(two times it will ask follow the on screen instructions always)

Now after that just reboot the system and it will prompt you for the LUKS passphrase and enter the correct one which you provided in the previous step.

Excellent you have done, and solved your problem
