I would like to watch television with my TV-Tuner. All I want is someone give me some steps to follow so I can find a driver. I am searching for several months but nothing. Also which application should I use for TV in Linux?
If the upstream Linux master your kernel was built from supports your TV tuner, the driver is already installed. If there is no support in your Linux kernel, but out-of-master support elsewhere, I'd advise you not to bother trying until it gets committed to master. There is a reason it is not in master yet.
If you are in Europe, you need to use software supporting the DVB standard.
DVB apps (in order of decreasing user friendliness):
If you are in North America, you need to use software supporting the ATSC standard.
tvtime or a similar program.
Identifying a PCI card or USB dongle
A lot of products share the same chips for receiving i.e. DVB content. If your chip is supported in Linux, usually any card with that chip will work. Your marketing product identification information is often of no use.
To find out more information about the chip in your computer and what level of support it has, use
lspci if it is a PCI card, use
lsusb if it is a USB dongle.
Usually if you Google the PCI ID with the word "Linux" you'll get relevant results.
I.e. if you have a device with the PCI ID
15a4:9016, Google it, and you will find the relevant chip name and information.
