- The IRIS RealityEngine provides two video outputs: a RGB video output
- (which is normally connected to the graphics monitor), and a composite
- video output. _v_o_u_t 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 _s_e_t_m_o_n man page for details on
- setting the graphics output VOF.
-
- _v_o_u_t provides the following controls:
-
- FFFFoooorrrrmmmmaaaatttt
- Select either NTSC (North American 525-line TV format), or PAL
- (European 625-line TV format) for the composite output.
-
- SSSSiiiiggggnnnnaaaallll
- 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.
-
- SSSSeeeetttt OOOOuuuuttttppppuuuutttt AAAArrrreeeeaaaa
- 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.
-
- WWWWiiiinnnnddddoooowwww SSSSiiiizzzzeeee
- 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.
-
- GGGGeeeennnnlllloooocccckkkk
- This selects either Stand Alone or Input as the genlock source. Note
- that this genlocks the RGB graphics output, and not the composite

- output.
-
- PPPPhhhhaaaasssseeee
- Two knobs (for coarse and fine) vary the genlock phase.
-
- _v_o_u_t provides the following menu selections:
-
- FFFFiiiilllleeee////QQQQuuuuiiiitttt
- Exit the vout program. No settings are saved.
-
- OOOOppppttttiiiioooonnnnssss////KKKKeeeeyyyy EEEEnnnnaaaabbbblllleeee
- This enables and disables the key signal.
-
- OOOOppppttttiiiioooonnnnssss////SSSSeeeettttuuuupppp
- Enable or disable the setup (sometimes called pedestal) from the
- composite video output.
-
- OOOOppppttttiiiioooonnnnssss////VVVViiiiddddeeeeoooo PPPPrrrroooo PPPPaaaannnneeeellll
- This launches a second window of controls, described below.
-
- SSSSyyyynnnncccc SSSSeeeelllleeeecccctttt
- 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 _v_o_u_t Encoder Controls window allows you to vary the following:
-
- GGGGeeeennnnlllloooocccckkkk DDDDeeeellllaaaayyyy

-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- ----xxxx xxxxooooffffffff
- Specify the initial x position of the right hand side of the encoder
- window.
-
- ----yyyy yyyyooooffffffff
- 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.
-
- ----mmmmooooddddeeee nnnnttttsssscccc||||ppppaaaallll
- Specify whether the encoder is to start up in NTSC or PAL mode. Note
- that the argument must be specified in lower case.

-
-
-
- ----qqqq
- 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.
-
- ----ffff
- Use the factory defaults, and not the previously saved user values.
- This flag is for use with the MultiChannel Option only.
-
- HHHHAAAARRRRDDDDWWWWAAAARRRREEEE
- _v_o_u_t works only on the IRIS RealityEngine, RealityEngine2, and VTX.

- setmon(1g)
-
- NNNNOOOOTTTTEEEESSSS
- The composite output may not be genlocked.
-
- If a MultiChannel Option board is installed, the operation of _v_o_u_t is
- totally different from that described above.
