NAME
tvtime-command - control a running tvtime process
SYNOPSIS
tvtime-command [COMMAND] ...
DESCRIPTION
tvtime-command allows a user to control a running tvtime process by sending it commands. It communicates with tvtime through a FIFO, otherwise known as a named pipe. Commands are case-insensitive, and are executed in order.
COMMANDS
AUTO_ADJUST_PICT
Restores the picture settings (brightness, contrast, hue,
colour) to their default values.
AUTO_ADJUST_WINDOW
Automatically resize the window to match the content inside it.
This is for when you resize tvtime into, say, a long rectangle,
and want it to jump back to being a perfect 4:3 box around the
content.
BRIGHTNESS_DOWN
Lowers the brightness setting on the input.
BRIGHTNESS_UP
Increases the brightness setting on the input.
CHANNEL_[0-9]
Simulates a keypad number press.
CHANNEL_ACTIVATE_ALL
Re-activates all channels in the list. Use this to re-
initialize the channel list before running the scanner if you
believe some channels are missing, or if new channels have
become available.
CHANNEL_DEC / CHANNEL_DOWN
Move one channel down in the channel list.
CHANNEL_INC / CHANNEL_UP
Move one channel up in the channel list.
CHANNEL_JUMP / CHANNEL_PREV
Changes to the last channel you were at. Useful for jumping
back and forth between two programs on distant channels.
CHANNEL_LIST
This command is used to bring up channel list.
CHANNEL_RENUMBER
Renumbers the current channel. This will swap the current
channel with the number you type in. Use this to configure your
station list to suit preference or locality.
CHANNEL_SAVE_TUNING
Saves the current fine tuning settings as a custom channel in
the station list.
CHANNEL_SCAN
Walks from the current position through the channel list,
disabling any channels for which no signal is detected. This
command is only available if signal checking is enabled.
CHANNEL_SKIP
Toggles the current channel as being active or disabled in the
station list. You can use this to manually scan your channels
and enable those with signal or disable duplicate stations.
COLOUR_DOWN / COLOR_DOWN
Decreases the input colour picture setting. This will make the
image less colourful until it is black-and-white.
COLOUR_UP / COLOR_UP
Increases the input colour picture setting. This will give the
image more colour.
CONTRAST_DOWN
Decreases the contrast setting of the input.
CONTRAST_UP
Increases the contrast setting of the input.
DISPLAY_INFO
This will re-display the OSD for the current channel, showing
the channel information, current deinterlacer and framerate, the
time, and input settings.
DISPLAY_MESSAGE
This will display a message along the bottom of the OSD. Useful
for cron jobs or other scripts to send notifications to a user
running tvtime.
DOWN This command provides the dual functionality of channel down or
menu arrow down, depending on whether the menu is currently
active. This command is to be used together with the LEFT,
RIGHT and UP commands.
ENTER Sends a virtual enter command. Use this when changing the
channel:
tvtime-command channel_1 channel_5 enter
will change to channel 15.
FINETUNE_DOWN
Decreases the fine tuning setting for the current channel.
FINETUNE_UP
Increases the fine tuning for the current channel.
HUE_DOWN
Decreases the hue setting of the input.
HUE_UP Increases the hue setting of the input.
KEY_EVENT
Sends a fake keystroke event to tvtime. This is useful for
doing complex operations via a remote control, as you can
indirect events to tvtime's internal key binding system.
LEFT This command provides the dual functionality of mixer volume
down or menu back command, depending on whether the menu is
currently active. This command is to be used together with the
RIGHT, UP and DOWN commands.
MENU_DOWN
In menu mode, this command moves the cursor down one entry in
the menu.
MENU_ENTER
In menu mode, this command selects the current entry or moves
forward one level in the menu.
MENU_EXIT
In menu mode, this command shuts off the menu.
MENU_BACK
In menu mode, this command moves back one level in the menu.
MENU_ENTER
In menu mode, this command selects the current entry or moves
forward one level in the menu.
MENU_UP
In menu mode, this command moves the cursor up one entry in the
menu.
MIXER_DOWN
Decreases the volume setting for the Line In device from
/dev/mixer. An optional parameter specifies the percentage to
decrease by.
MIXER_TOGGLE_MUTE
Toggles the mute status with the mixer, and not with the capture
card like TOGGLE_MUTE does.
MIXER_UP
Increases the volume setting for the Line In device from
/dev/mixer. An optional parameter specifies the percentage to
increase by.
NOOP The command to do nothing. Useful for when you want to blank
out one of the default key bindings in tvtime.
OVERSCAN_DOWN
Decreases the overscan compensation amount. This will show more
of the captured input.
OVERSCAN_UP
Increases the overscan compensation amount. This will show less
of the captured input.
PICTURE
Selects which picture setting (brightness/contrast/colour/hue)
to change using the PICTURE_UP and PICTURE_DOWN commands.
PICTURE_UP
Increases the current picture setting value
(brightness/contrast/colour/hue).
PICTURE_DOWN
Decreases the current picture setting value
(brightness/contrast/colour/hue).
RESTART
Asks tvtime to restart itself. This is used in the menu when we
have changed a value that we can't yet change at runtime.
RIGHT This command provides the dual functionality of mixer volume up
or menu enter command, depending on whether the menu is
currently active. This command is to be used together with the
LEFT, UP and DOWN commands.
RUN_COMMAND
Instructs tvtime to spawn a command. This can be used to start
a program using a key in tvtime or lirc, such as to spawn
mythepg or alevt. Using tvtime-command run_command "xterm" will

directory listed as the screenshot directory in the tvtime.xml
configuration file. The default is the running user's home
directory.
SET_AUDIO_MODE
This command takes a parameter and sets the current audio mode.
Valid options are "mono", "stereo", "sap", "lang1" or "lang2".
SET_DEINTERLACER
This command takes a parameter and sets the current
deinterlacer. Valid options are the short name of any of the
deinterlacers available in tvtime.

input (0-n). Among the Inputs are: the tuner, composite, or S-
Video connectors on the capture card.
SET_INPUT_WIDTH
This command takes a parameter and sets the current input width
in pixels. It will be used in tvtime after a restart.
SET_MATTE
This command sets the matte to apply to the output. This

watching a 2.35:1 movie in a long, thin window, or for watching
it at the top of the screen using the fullscreen position
option. Valid options here are 16:9, 1.85:1, 2.35:1 or 4:3.
SET_NORM
This command takes a parameter and sets the current television
standard. It will be used in tvtime after a restart.

deinterlacer setting.
SHOW_EPG
Shows TV Guide using the TV listings from XMLTV.
SHOW_MENU
This command is used to bring up the tvtime setup menu.
SHOW_STATS
Shows a debug screen showing statistics about the running
instance of tvtime.
SLEEP This command sets the sleep timer to tell tvtime to shut itself
off after a certain amount of time. Sending this command will
first activate the feature, and sending it again will increase
the timer up until a maximum value at which point it is shut
off.
TOGGLE_ALWAYSONTOP
If supported by your window manager, this command will ask to
have the window be put into an "always on top" state, where no
other window can be stacked above it.
TOGGLE_ASPECT
Toggles the display between 4:3 and 16:9 mode. Use 16:9 mode if
you have configured an external DVD player or satellite receiver
to output anamorphic 16:9 content.
TOGGLE_AUDIO_MODE
Toggles between the available audio modes on this channel. It
can take some time before the driver discovers that modes are
available.
TOGGLE_BARS
Asks tvtime to display colourbars. The colourbars are generated
by tvtime and are not related to the capture card, but simply to
help configure your video card and display device. Once your
settings are correct with these colourbars, try colourbars from
an input source like an external DVD player and make sure they
match up.
TOGGLE_CC
Enables closed caption information to be displayed in the tvtime
window. Closed captioning is only available if you have enabled
VBI reading in your tvtime.xml configuration file.
TOGGLE_CHANNEL_PAL_DK
For PAL users, toggles the audio mode of the current channel
between the PAL-BG and PAL-DK audio norms.
TOGGLE_CHROMA_KILL
Enables or disables the chroma killer filter, which makes the
input black and white. Useful when watching a black-and-white
movie to avoid chrominance artifacts.
TOGGLE_COLOR_INVERT / TOGGLE_COLOUR_INVERT
Turns on or off the colour invert filter. This is (apparently)
useful for users of the Australian cable company Optus who want
to avoid using the decryption boxes and tune using their capture
card directly.
TOGGLE_DEINTERLACER
This toggles between the available deinterlacing methods.
TOGGLE_FULLSCREEN
This toggles between fullscreen and windowed mode.
TOGGLE_FRAMERATE
Toggles the framerate at which tvtime will output. Options are
full frame rate (every field deinterlaced to a frame), half
frame rate TFF (every top field deinterlaced to a frame) and
half frame rate BFF (every bottom field deinterlaced to a
frame).
TOGGLE_INPUT
Switches the capture card input used. Among the Inputs are: the
tuner, composite, or S-Video connectors on the capture card.
TOGGLE_MATTE
Switches between the available mattes. This cuts off the top
and bottom of the input picture to help fit the window to the
image content.
TOGGLE_MIRROR
Turns on or off the mirror filter, which flips the input. This
is useful for using tvtime with mirroring projectors, although I
don't think it will actually work as intended yet since we don't
mirror the OSD output. :) Comments appreciated.
TOGGLE_MUTE
Toggles the mute state in the capture card (and not in your
soundcard).
TOGGLE_NTSC_CABLE_MODE
Toggles the NTSC cable mode settings: Standard, IRC, and HRC are
available.
TOGGLE_PAL_DK_AUDIO
For PAL users, toggles the default audio mode of all channels
between the PAL-BG and PAL-DK audio norms.
TOGGLE_PAL_SECAM
Toggles between PAL and SECAM on the current channel. This
feature is useful for regions which receive both PAL and SECAM
channels, such that tvtime can be configured on a per-channel
basis for the correct norm.
TOGGLE_PAUSE
Enters pause mode. Pause mode is a debugging feature used to
test deinterlacer filters by allowing to see the output of a
single set of frames with various deinterlacers.
TOGGLE_PULLDOWN_DETECTION
Enables or disables the 2--3 pulldown detection feature for NTSC
input.
TOGGLE_QUIET_SCREENSHOTS
When this option is turned on, screenshots will not announce
themselves on the OSD. This is useful if you intend to take a
lot of screenshots, and don't want the text to interrupt your TV
watching or appear in other screenshots.
TOGGLE_SIGNAL_DETECTION
Toggles on and off tvtime's signal detection code. Signal
detection enables features like channel scanning and increases
responsiveness on channels with poor reception, but may make it
impossible to watch stations where the reception is too bad for
the card to detect it reliably.
TOGGLE_XDS
Toggles on and off tvtime's XDS decoding code. XDS is used to
send information about the channel including the network name
and call letters, and sometimes information about the current
show. This information is then shown on the OSD and saved to
the stationlist.xml file.
TOGGLE_XMLTV_LANGUAGE
Toggles which language to show by default from the XMLTV file
from the ones available in the file.
UP This command provides the dual functionality of channel up or
menu arrow up, depending on whether the menu is currently
active. This command is to be used together with the LEFT,
RIGHT and DOWN commands.
QUIT Asks the running tvtime process to exit.
