NAME
tvtime - a high quality television application
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.
USAGE
Here are the core set of key bindings you want to learn for using tvtime:
Escape or q Quit
F1 or tab Show menu
up/down Change channels
0-9 and Enter Change channels
Backspace Jump to previous channel
i Change input
m Mute
+/- or left/right Volume control
f Fullscreen
s Take a screenshot
Enter Display info
d Display debug statistics
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
