Once
you are getting video output from that device (typically available from /dev/video0), you can try
out a couple of applications to begin using it.
This section explores the tvtime program for watching television and the Ekiga program for video
conferencing.
Watching TV with tvtime
The tvtime program (tvtime command) enables you to display video output??”television channels,
in particular??”on your desktop. You can change the channels, adjust the volume, and fine-tune
your picture. In addition, tvtime sports a slick onscreen display and support for a widescreen display.
The following sections describe how to choose a TV capture card and use tvtime to watch television
on your desktop.
Getting a Supported TV Card
Video4Linux (V4l/V4l2) is the video interface available for Linux. It supports a variety of TV capture
cards and cameras, and is included in some distributions. If your distribution does not include V4l
or V4L2, you can install it on your own, although it is not the easiest task to accomplish. For more
information about obtaining and installing V4l and the appropriate driver, visit http://linux
.bytesex.org/v4l2/index.html.
To see a list of supported TV cards that you can use with tvtime, refer to the CARDLIST and
Cards files of your V4l installation.
