is running, as your changes may be overwritten.
The global syntax is as follows:
<!DOCTYPE tvtime PUBLIC "-//tvtime//DTD tvtime 1.0//EN"
You can find the DTD and other information about the XML configuration
supports a multitude of options. The <option> tag should be contained
within a <tvtime> tag.
The following is a list of options and their default values, along with
a description of what the option does.
- <option name="Verbose" value="0"/>
The verbose setting indicates that we should print full informational
and warning messages to stderr while running
Otherwise, only fatal errors will be printed to the output.
- <option name="V4LDevice" value="/dev/video0"/>
This sets the default capture device to use.
- <option name="V4LInput" value="0"/>
This sets the default capture card input to be opened by
For example, for my WinTV card has the tuner as source
and its composite input as source
Sources can be changed at runtime using the
command, which is key command "i" by default.
- <option name="Norm" value="NTSC"/>
This sets the default TV norm. Valid options are:
- <option name="SaveAndRestorePictureSettings" value="1"/>
This option indicates whether
should enable its own saving and restoring of picture settings,
both on startup and per channel change.
- <option name="AudioMode" value="stereo"/>
This option saves the last used audio mode. This will be used to
remember which audio mode to select when the application is next
started. Valid options here are "mono", "stereo", "lang1", "lang2"
- <option name="AudioBoost" value="-1"/>
This option sets the audio boost. This is a percentage for how
much to set the volume coming out of the capture card. By default,
tvtime does not set the audio at all. However, because the volume
sometimes does not have a sane default, or is reset by other
applications, you can use this value to have it always set to your
favorite volume. Use -1 to have tvtime not touch the volume.
- <option name="ShowCC" value="0"/>
This option saves the state of closed caption decoding. Closed
captions are an NTSC-specific text version of the audio for the
- <option name="ColourInvert" value="0"/>
This value saves the on-off state of the colour invert filter across
- <option name="MirrorInput" value="0"/>
This value saves the on-off state of the mirror filter across sessions.
- <option name="Frequencies" value="US-Cable"/>
This sets the default frequency table to use for any tuners found.
- <option name="NTSCCableMode" value="Standard"/>
There are two special NTSC cable standards in the US: IRC and HRC.
In IRC, channels 5 and 6 are on different frequencies, and HRC mode
shifts all frequencies up by 1.25MHz (and is also weird on channels 5
and 6). Use this option to set the cable mode to
It is very rare that you will see cable systems that use IRC or
- <option name="CheckForSignal" value="1"/>
should check if there is a signal present when changing channels etc.
If your card doesn't suck, you shouldn't need to shut this off.
Disabling this feature will also disable the channel scanner.
- <option name="InputWidth" value="720"/>
This sets how many pixels per scanline to request from the capture card.
A higher setting gives better quality, while a lower setting means we do
less work, and so
will run faster. If you have a slower CPU (like, less than 500Mhz or
so), maybe values of
480 or 400
might suit you best. For best quality, choose a high value like
720 or 768.
Most capture cards cannot sample higher than
pixels per scanline.
- <option name="XMLTVFile" value="none"/>
Set this to a filename to get show listings from an xmltv file.
Set to "none" if you do not wish to use xmltv.
- <option name="XMLTVLanguage" value="none"/>
Set this to a two-letter language code to set the language to use
for entries in the XMLTV file (for example, use "de" for German).
Set to "none" if you wish to use the default language of the file.
- <option name="UseXDS" value="0"/>
Set this to
to enable XDS channel information decoding. This
option is specific to NTSC regions. XDS is used to send information
about the channel including the network name and call letters, and
sometimes information about the current show.
- <option name="VBIDevice" value="/dev/vbi0"/>
This sets which device to use for VBI decoding.
- <option name="MixerDevice" value="/dev/mixer:line"/>
This sets the mixer device and channel to use. The format is device
name:channel name for OSS mixer (e.g., "/dev/mixer:Line") or device/channel
for ALSA (e.g., "hw:0/CD").
Valid OSS channels are:
vol, bass, treble, synth, pcm, speaker,
line, mic, cd, mix, pcm2, rec,
igain, ogain, line1, line2, line3,
dig1, dig2, dig3, phin, phout, video,
- <option name="SquarePixels" value="1"/>
Disabling this option tells tvtime to use the X server DPI to determine
pixel shape. By default, tvtime assumes pixels are square. Set this
to 0 if you have a 4:3 monitor but run it at 1280x1024 and want tvtime
to do the right thing.
- <option name="Widescreen" value="0"/>
This option enables 16:9 aspect ratio mode by default on startup.
- <option name="WindowGeometry" value="0x576"/>
Sets the geometry of the window. A width value of 0 signifies that the
appropriate width for the given height will be used. For 4:3 content
on a square pixel display, this defaults to a
- <option name="Overscan" value="0.0"/>
This sets the percent of the sides to leave to the overscan, that is,
don't show them at all. Safe action area on a television is 10% in
the overscan, but that's a bit restrictive. If you want
to look like a TV, a good value would be about 6-8%. The value is
in percent, so for 8%, use
- <option name="Fullscreen" value="0"/>
Set this to
start in fullscreen mode. This setting is set at runtime so that when
in fullscreen, starting it again will start back in fullscreen mode.
- <option name="AlwaysOnTop" value="0"/>
Set this to
start in always-on-top mode under supporting window managers. This
setting is set at runtime so that when you quit
in always-on-top mode, starting it again will start back in
- <option name="FullscreenPosition" value="Centre"/>
Sets the position of the output when in fullscreen mode:
When set to
in fullscreen will place its output at the top of the screen. Use
if you have a projector to help
fit properly onto your screen.
- <option name="FramerateMode" value="0"/>
This sets the framerate of the output from
Full framerate mode, every field is deinterlaced.
59.94fps for NTSC, 50fps for PAL.
Half framerate mode, deinterlace every top field to a frame (TFF).
29.97fps for NTSC, 25fps for PAL.
Half framerate mode, deinterlace every bottom field to a frame (BFF).
29.97fps for NTSC, 25fps for PAL.
The two half framerate modes are useful for progressive content from
video game consoles. Use weave and select either TFF or BFF, whichever
does not exhibit interlace effects.
- <option name="QuietScreenshots" value="0"/>
When this option is turned on, screenshots will not announce themselves
on the OSD. This is useful if you intend to take a lot of screenshots,
and don't want the text to interrupt your TV watching or appear in other
- <option name="ProcessPriority" value="-10"/>
Sets the default process priority. By default,
tries to set itself at a priority of
which higher than normal applications. Acceptable values are from
-20 to 20,
with lower values meaning higher priority.
- <option name="TimeFormat" value="%X"/>
Sets the time format to be used in the
on-screen display. The format is a string in the same format as
The default is to use the time format of your locale.
- <option name="ScreenShotDir" value="~"/>
This is the default directory in which screenshots are placed.
The default is to save them into the user's home directory.
<option name="ChannelTextFG" value="0xFFFFFF00"/>
<option name="OtherTextFG" value="0xFFF5DEB3"/>
These options set the ARGB colours used for the text in the on-screen
display. The default for the channel name is "yellow"
and the default for the surrounding text is "wheat"
The colour format can be hexadecimal or decimal. If the alpha channel
is not specified the default is "opaque"
255 255 0,
- <option name="UnmuteVolume" value="-1"/>
This setting saves the volume before muting across tvtime sessions.
You should not ever need to set this yourself.
- <option name="Muted" value="0"/>
This setting saves whether or not tvtime was muted when it was last
exited. You should not ever need to set this yourself.
- <option name="MuteOnExit" value="0"/>
This setting controls whether tvtime should mute its mixer device on
exit. Use this to work around noisy capture cards.
- <option name="ShowTaglines" value="1"/>
This setting controls whether tvtime should show the silly taglines
in the window title bar. Set to 0 to shut them off.
- <option name="PrevChannel" value="2"/>
This setting is saved at runtime to remember the previous channel.
- <option name="Channel" value="2"/>
This setting is saved at runtime to remember the current channel.
- <option name="DeinterlaceMethod" value="AdaptiveAdvanced"/>
This setting is saved at runtime to remember the deinterlacer used.
Supported deinterlacers are:
Television: Full Resolution
Television: Half Resolution
Motion Adaptive: Motion Search
Motion Adaptive: Advanced Detection
Motion Adaptive: Simple Detection
Progressive: Top Field First
Progressive: Bottom Field First
