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

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).

NTSC |
• |
PAL |
• |
SECAM |
• |
PAL-NC |

- -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.
