1. Introduction

This document was written to assist the reader in setting up and configuring TV tuner cards based on the Bt848 or Bt878 chipsets in the Linux operating system. It outlines how to enable the necessary kernel and/or software support and various television applications and software methods of capture usable with your device. While there is some attempt to catalog individual cards and features in Appendix C, the ultimate best source of information about your card and its capabilities will be found in the printed manual that came with your device or the manufacturer's website.

1.6. Conventions Used in this Document

The following conventions are used in this document and are outlined here for those who may not yet have a complete understanding of how to access and control the underlying operating system in Linux, which is usually via the Bash shell.

First, filenames are referenced in a paragraph like so: /path/file

Commands in Linux are executed (or 'called') at the command prompt, otherwise known as the 'command line.' If you are in the non-graphical (text-based) environment, you will usually be presented with the Bash shell prompt which is a dollar sign:

   $

...or the hash mark:

   #

...if you have logged in as root or have otherwise acquired root, or 'superuser' privileges. You can also access the Bash shell in the X window system, otherwise known as X or X11, with an xterm or similar X-terminal-emulator. Commands to be performed at the Bash prompt, but referenced in a paragraph of this document, usually look like this: do this now

Commands and/or the resulting output of commands may also be outlined with screen output in their own paragraph or heading:

   $ date
   Sun Jul 27 22:37:11 CDT 2003

When a command is written in front of the Bash prompt (e.g., $ date above), it is assumed the [Return] or [Enter] key has been pressed after the command, possibly followed by the output on a new line as shown in the preceding example.
