.SH NAME
tvtime \- a high quality television application

.SH SYNOPSIS

.B tvtime
[
.IR OPTION
] ...

.SH DESCRIPTION

.B tvtime
is a high quality television application for use with video capture
cards.
.B tvtime
processes the input from a capture card and displays it on a computer
monitor or projector.

.B tvtime
supports:

.IP \(bu 4
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.

.IP \(bu
Multiple deinterlacing algorithms for finding the optimal mode for the
video content and available processor speed.

.IP \(bu
16:9 aspect ratio mode for the highest available resolution when
processing input from an external DVD player or digital satellite
receiver.

.IP \(bu
A super\-slick on\-screen\-display for the complete television
experience, with a featureful menu system.

.RE

.SH OPTIONS

.TP
.B \-a, \-\-widescreen
This option starts
.B tvtime
in 16:9 aspect ratio mode.

.TP
.B \-A, \-\-nowidescreen
This option starts
.B tvtime
in 4:3 aspect ratio mode.

.TP
.B \-h, \-\-help
Show usage information.

.TP
.B \-k, \-\-slave
Disables keyboard input in
.B tvtime
for slave mode.  Slave mode was added
for integration with PVR applications like
.B freevo
or
.BR mythtv ,
so that
.B freevo
can handle keyboard input while
.B 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
.BR tvtime\-command .

.TP
.B \-m, \-\-fullscreen
Start
.B tvtime
in fullscreen mode.

.TP
.B \-M, \-\-window
Start
.B tvtime
in windowed mode.

.TP
.B \-s, \-\-showdrops
Print frame skip information (for debugging).

.TP
.B \-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.

.TP
.B \-v, \-\-verbose
The verbose setting indicates that we should print full informational
and warning messages to standard error while running
.BR tvtime .
Otherwise,
only critical errors will be printed to the output.

.TP
.B \-F, \-\-configfile=FILE
Additional config file to load settings from.

.TP
.B \-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 
.RI 768\[mu] 576
window.

.TP
.B -I, \-\-inputwidth=SAMPLING
V4L input scanline sampling (defaults to
.IR 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
.B tvtime
will run faster.  If you have a slower CPU
(like, less than 500Mhz or so), maybe values of
.IR 480 \ or\  400
might suit you best.  For best quality, choose a high value like
.IR 720 \ or\  768 .
Many capture cards cannot sample higher than
.I 768
pixels per scanline.

.TP
.B \-d, \-\-device=NAME
video4linux device to use (defaults to
.IR /dev/video0 ).

.TP
.B \-b, \-\-vbidevice=DEVICE
VBI device to use (defaults to
.IR /dev/vbi0 ).

.TP
.B \-i, \-\-input=INPUTNUM
video4linux input number (defaults to
.IR 0 ).
Cards commonly have a bunch
of sources, for example, on my WinTV card,
.I source 0
is my tuner and
.I source 1
is the composite input.

.TP
.B \-c, \-\-channel=CHANNEL
On startup,
.B tvtime
will tune to the given channel.  Otherwise, the
channels from the config file will be used.

.TP
.B \-n, \-\-norm=NORM
The mode to set the tuner to (defaults to
.IR NTSC ).
Valid modes are:
.TS
nokeep tab (@);
l l.
\(bu@NTSC
\(bu@PAL
\(bu@SECAM
\(bu@PAL\-NC
\(bu@PAL\-M
\(bu@PAL\-N
\(bu@NTSC\-JP
.TE

.TP
.B \-f, \-\-frequencies=NAME
The channels you are receiving with the tuner (defaults to
.IR us\-cable ).
Valid values are:
.TS
nokeep tab (@);
l l.
\(bu@us\-cable
\(bu@us\-broadcast

\(bu@france
\(bu@russia
\(bu@custom (first run 'tvtime-scanner')
.TE

.TP
.B \-t, \-\-xmltv=FILE
Reads XMLTV listings from the given file to display on the OSD.  Channels
are looked up based on their name, and
.B tvtime
will display the show title, sub-title
and show description on the OSD.

.TP
.B \-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"


.TP
.B \-X, \-\-display=DISPLAY
Uses the given X display to connect to.

.TP
.B \-x, \-\-mixer=DEVICE[:CH]
The mixer device and channel for the volume controls. (defaults to
.IR /dev/mixer:line ).
Valid channels are:
.TS
nokeep tab (@);
