NAME
     vout - composite video output control panel

SYNOPSIS
     vout [-x xoff] [-y yoff] [-mode ntsc|pal] [-q] -[f]

DESCRIPTION
     The IRIS RealityEngine provides two video outputs: a RGB video output
     (which is normally connected to the graphics monitor), and a composite
     video output.  vout provides an easy-to-use graphical interface to
     control the composite output. It also controls several parameters of the
     RGB video output.

     The composite output is available at the BNC connector labeled
     `composite', and at the S-Video connector. Both connections show the same
     signal. The video output is always a region of the graphics screen; the
     region that is output is selected by the `Set Output Area' button.

     The composite output is only available when running a standard VOF on the
     graphics output. It is not available when running an interlaced, field
     sequential, or stereo VOF; or when running a VOF that is smaller in area
     than the desired composite output. See the setmon man page for details on
     setting the graphics output VOF.

     vout provides the following controls:

     Format
          Select either NTSC (North American 525-line TV format), or PAL
          (European 625-line TV format) for the composite output.

     Signal
          This selects the type of signal connected to the genlock input:
          either a noisy signal (typically from a VCR), or a clean signal
          (labelled Other).  This should normally be set to Other, unless you
          are having problems genlocking to your signal source.

     Set Output Area
          Allows you to select the area of the screen to be sent to the
          composite output. The selected area coordinates are shown in the
          Lower Left X and Y boxes. Alternately, numbers may be directly
          entered in these boxes.  Note that the hardware requres that the X
          coordinate be a multiple of 5; vout will automatically round it
          appropriately.

     Window Size
          This is the size (in pixels) of the composite output. This is
          automatically changed to 646 x 486 in NTSC mode, and 768 x 576 in
          PAL mode.

     Genlock
          This selects either Stand Alone or Input as the genlock source. Note
          that this genlocks the RGB graphics output, and not the composite


          output.

     Phase
          Two knobs (for coarse and fine) vary the genlock phase.

     vout provides the following menu selections:

     File/Quit
          Exit the vout program. No settings are saved.

     Options/Key Enable
          This enables and disables the key signal.

     Options/Setup
          Enable or disable the setup (sometimes called pedestal) from the
          composite video output.

     Options/Video Pro Panel
          This launches a second window of controls, described below.

     Sync Select
          This allows you to individually enable and disable sync on the Red,
          Green, Blue, and Alpha channels. This affects the RGB output, and
          not the composite output.

     The  vout Encoder Controls window allows you to vary the following:

     Genlock Delay

     Chroma Phase

     Chroma Center

     H phase

OPTIONS
     -x  xoff
          Specify the initial x position of the right hand side of the encoder
          window.

     -y  yoff
          Specify the initial y position of the bottom of the encoder window.
          Note that 0 is the top of the screen; therefore, to place the
          encoder window at the bottom of a 1280 x 1024 screen, you would
          specify -y 1023.

     -mode  ntsc|pal
          Specify whether the encoder is to start up in NTSC or PAL mode. Note
          that the argument must be specified in lower case.


     -q
          Don't enter vout; process and set the -x, -y, and -mode flags, and
          then exit. This is useful for setting the encoder from a program or
          shell script.

     -f
          Use the factory defaults, and not the previously saved user values.
          This flag is for use with the MultiChannel Option only.

HARDWARE
     vout works only on the IRIS RealityEngine, RealityEngine2, and VTX.

NOTES
     The composite output may not be genlocked.

     If a MultiChannel Option board is installed, the operation of vout is
     totally different from that described above.
