tvtime - a high quality television application
tvtime [ OPTION ] ...
tvtime is a high quality television application for use with video cap-
ture cards. tvtime processes the input from a capture card and dis-
plays it on a computer monitor or projector.
· 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
· A super-slick on-screen-display for the complete television experi-
ence, with a featureful menu system.
Here are the core set of key bindings you want to learn for using
Escape or q Quit
F1 or tab Show menu

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
e Toggle audio mode (stereo/mono/SAP)
v Toggle always-on-top with supporting window managers
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)
This option starts tvtime in 16:9 aspect ratio mode.
This option starts tvtime in 4:3 aspect ratio mode.
Show usage information.
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.
Start tvtime in fullscreen mode.
Start tvtime in windowed mode.
Print frame skip information (for debugging).
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 out-
put window height.
The verbose setting indicates that we should print full informa-
tional and warning messages to standard error while running
tvtime. Otherwise, only critical errors will be printed to the
Additional config file to load settings from.
Sets the geometry of the window, for example, 400x300 for a win-
dow 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.
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.
video4linux device to use (defaults to /dev/video0).
VBI device to use (defaults to /dev/vbi0).
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.
On startup, tvtime will tune to the given channel. Otherwise,
the channels from the config file will be used.
The mode to set the tuner to (defaults to NTSC). Valid modes
The channels you are receiving with the tuner (defaults to
us-cable). Valid values are:
· custom (first run ’tvtime-scanner’)
Reads XMLTV listings from the given file to display on the OSD.
Channels are looked up based on their name, and tvtime will dis-
play the show title, sub-title and show description on the OSD.
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"
Uses the given X display to connect to.
The mixer device and channel for the volume controls. (defaults
to /dev/mixer:line). Valid channels are:
Billy Biggs, Doug Bell, Alexander S. Belov, Achim Schneider, David I.
Lehn, Paul Jara, Robert Högberg, Craig Dooley, Bart Dorsey, Nicolas
Boos, Simon Law, Mark Trolley, Joachim Koenig, Stewart Allen, Justin A,
Brian Goines, Krister Lagerstrom.
