SYNOPSIS
tvtime [ OPTION ] ...
DESCRIPTION
tvtime is a high quality television application for use with video capture cards. tvtime processes the input from a capture card and displays it on a computer monitor or projector.
tvtime supports:
-
Deinterlaced output at full interlaced rate of 59.94 frames per second
for NTSC source, or 50 frames per second for PAL sources. This gives
smoothness of motion and high visual quality.
-
Multiple deinterlacing algorithms for finding the optimal mode for the
video content and available processor speed.
-
16:9 aspect ratio mode for the highest available resolution when
processing input from an external DVD player or digital satellite
receiver.
-
A super-slick on-screen-display for the complete television
experience, with a featureful menu system.

Here are some advanced keys. These features are all configurable via the menu, but some of these may be useful if you use the features often:
-
- e
- Toggle audio mode (stereo/mono/SAP)
- v
- Toggle always-on-top with supporting window managers
- F5/F6/F7
- Picture settings
- Space
- Restore default picture settings
- /
- Resize the window to match the content inside it (after applying a matte or switching to 16:9 mode)
- c
- Toggle closed caption decoding (NTSC only)
OPTIONS
- -a, --widescreen
-
This option starts
tvtime
in 16:9 aspect ratio mode.
- -A, --nowidescreen
-
This option starts
tvtime
in 4:3 aspect ratio mode.
- -h, --help
-
Show usage information.
- -k, --slave
-
Disables keyboard input in
tvtime
for slave mode. Slave mode was added
for integration with PVR applications like
freevo
or
mythtv,
so that
freevo
can handle keyboard input while
tvtime
is running. In slave mode, keystrokes are ignored but they are
printed to standard output, and commands are read from standard input in
the same syntax as
tvtime-command.
- -m, --fullscreen
-
Start
tvtime
in fullscreen mode.
- -M, --window
-
Start
tvtime
in windowed mode.
- -s, --showdrops
-
Print frame skip information (for debugging).
- -S, --saveoptions
-
Save command line options to the config file. This will save the V4L
device, VBI device, input number, norm, frequency, startup fullscreen
setting, aspect ratio, verbose mode, and output window height.
- -v, --verbose
-
The verbose setting indicates that we should print full informational
and warning messages to standard error while running
tvtime.
Otherwise,
only critical errors will be printed to the output.
- -F, --configfile=FILE
-
Additional config file to load settings from.
- -g, --geometry=GEOMETRY
-
Sets the geometry of the window, for example, 400x300 for a window 400
pixels wide and 300 pixels tall. 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
768×576
window.
- -I, --inputwidth=SAMPLING
-
V4L input scanline sampling (defaults to
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
tvtime
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.
Many capture cards cannot sample higher than
768
pixels per scanline.
- -d, --device=NAME
-
video4linux device to use (defaults to
/dev/video0).
- -b, --vbidevice=DEVICE
-
VBI device to use (defaults to
/dev/vbi0).
- -i, --input=INPUTNUM
-
video4linux input number (defaults to
0).
Cards commonly have a bunch
of sources, for example, on my WinTV card,
source 0
is my tuner and
source 1
is the composite input.
- -c, --channel=CHANNEL
-
On startup,
tvtime
will tune to the given channel. Otherwise, the
channels from the config file will be used.
- -n, --norm=NORM
-
The mode to set the tuner to (defaults to
NTSC).
Valid modes are:
• NTSC • PAL • SECAM • PAL-NC • PAL-M • PAL-N • NTSC-JP - -f, --frequencies=NAME
-
The channels you are receiving with the tuner (defaults to
us-cable).
Valid values are:
• us-cable • us-broadcast • japan-cable • japan-broadcast • europe • australia • australia-optus • newzealand • france • russia • custom (first run 'tvtime-scanner') - -t, --xmltv=FILE
-
Reads XMLTV listings from the given file to display on the OSD. Channels
are looked up based on their name, and
tvtime
will display the show title, sub-title
and show description on the OSD.
- -l, --xmltvlanguage=LANG
-
Use XMLTV data in given language, if available. Languages are represented
by their two-letter language code (for example, "de" for German). The
default language used in the file will be used if this is unset or
set to "none"
- -X, --display=DISPLAY
-
Uses the given X display to connect to.
- -x, --mixer=DEVICE[:CH]
-
The mixer device and channel for the volume controls. (defaults to
/dev/mixer:line).
Valid 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 • radio • monitor
