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_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_LEFT
              In menu mode, this command moves back one level in the menu.

       MENU_RIGHT
              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_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.
