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 have tvtime call system( "xterm &" ).

SAVE_PICTURE_GLOBAL
Saves the current picture settings as the global defaults.

SAVE_PICTURE_CHANNEL
Saves the current picture settings as the defaults for the current channel on the
tuner.

SCREENSHOT
Asks tvtime to take a screenshot. Screenshots are saved to the 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.

SET_FRAMERATE
This command takes a parameter and sets the current framerate. Valid options are
"full", "top" and "bottom".

SET_FREQUENCY_TABLE
This command takes a parameter and sets the current frequency table.

SET_FULLSCREEN_POSITION
This command sets where widescreen output will be aligned when in fullscreen mode,
either top for the top of the screen, center, or bottom.

SET_INPUT
This command takes a parameter and sets the the capture card 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 changes the size of the
output window, and is useful for 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.

SET_STATION
This command takes a station name or number as a parameter and changes the channel
to the station given.

SET_XMLTV_LANGUAGE
Set the preferred language code for XMLTV data. The argument can be either the two-
letter language code according to ISO 639 or a number to select one of the known
languages.

SHOW_DEINTERLACER_INFO
Shows a help screen on the OSD describing the current 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.
