How to use a TV (video) card in Linux (1)

Many people haveTV cardAlthough the manufacturer of your TV card may not provideLinux.

However, Linux provides support for common bt8x8 chips in video cards.

If conditions are met, start the operation.

In Linux, video card support is implemented by Video4Linux, which is generally referred to as V4L.

Now the Linux kernel of a higher version includes V4L, and the default startup kernel has

V4L has been compiled in build-in or module mode. So in general, the Linux

After installation, you can directly use V4L .. If you compile

Pay attention to the following configurations. First, select and compile Mulitmedia devies --> Video for Linux,

Go to Mulitmedia devies --> Video for Linux --> according to the type of your TV card

Line configuration. If you are not sure, select all the items (compile according to the module)

For TV cards that support the FM radio function, configure Mulitmedia devies as shown above -->

Radio Adapters, you may also need to select Character devies --> I2C support -->

I2C Support, I2C device interface, I2C bit-banging interface in and below it

You also need to select Sound --> TV Card (bt848) mixer support.

In order to achieve better support, do you think the exception is complicated? Fortunately, the default installation method has been completed for us.

All we have to do is directly configure the video card parameters.

If your E file is good enough, you 'd better check

The description in video4linux/bttv. Due to the differences between different TV cards, I am not arrogant, so I have

Follow my TV card (zoltrix TV-MAX use bt848chip & Philips Pal D/K Tuner)

You need to configure the/etc/modules. conf file:

For example, the value of modueles. conf is

1 alias parport_lowlevel parport_pc

2 alias eth0 tulip

3 alias sound-slot-0 ymfpci

4 post-install sound-slot-0/bin/aumix-minimal-f/etc/. aumixrc-L>/dev/null 2> & 1 |:

5 pre-remove sound-slot-0/bin/aumix-minimal-f/etc/. aumixrc-S>/dev/null 2> & 1 |:

6 alias char-major-81 bttv

7 alias usb-controller usb-uhci

Add

A pre-install bttv modprobe-k tuner

B options bttv radio = 1 card = 15

C options tuner type = 23

Radio = 1 in line B indicates that the video card supports sound. card = 15 indicates the TV card manufacturer ID,

15 stands for Zoltrix TV-MAX, c behavior TV card tuner number, 23 stands for Philips PAL D/K

You can view the list of video4linux/bttv/CARDLIST files in the current kernel documentation

Configure your TV card.

After the configuration is complete, restart and install the program.

I like xawtv because I have many Program Programs in Linux. The installation of xawtv is similar to that of other software,

The download is generally the source code, so under the root user, xawtv -???. Decompress gz.tar and enter

The unzipped sub-directories are as follows:./configure; make install and other steps,

If no error occurs, run xawtv (preferably as root). Select Frequency table.

For china-bcast, the keyboard is set up or down, and the left and right are fine-tuned. If you can see the screen and hear

Congratulations, otherwise, adjust the parameters of modules. conf. If you have any questions

Let's take a look at the descriptions on the TV card in the Linux Howto file. I just benefited a lot from it.

I wish you success.
