Transparent background is not specified in the scene file but in
the command-line options, using the option +ua (ie. "use alpha").
This can be written in the command-line text field in the windows
version or a proper .ini file (or if you are using a command-line
version of POV-Ray, then of course right in the command line).
Note that in order for POV-Ray to be able to save the alpha channel
to the image file, you have to use a format which supports alpha channel,
such as for example PNG.

Yes I'm sorry I have forgotten the subject.
I have read the "output_file_type" it looks like difficult. Where I have to
put this, in the background? "background { ??? }" I only want a transparent
background not configure my graphic target.

Mentioned subchapter is enclosed in chapter about POV-Ray options. Those
options can be located in command line when POV-Ray is launched and/or in
ini-file readed prior parsing/rendering your scene and/or in platform specific
place like command-line in toolbar in Windows port.
Try to browse manual, this is way to wide subject to be explained in simple
post.

I do not know what do you mean as "graphic target", but you cannot have
transparent background if you do not have transparency/aplha support in file
format you are rendering into.

"You may turn this option on with Output_Alpha=on or +UA. The default is off
or -UA."
I don't understand where I have to activate it.
=====================================
background { White }
camera {location <170, -11, -110>look_at <180, -15, -16>}
light_source { <170, -30, -100> color White}
=====================================
I'm sorry.

Not in your .pov file. I assume you're running POV-Ray for Windows, in which
the correct place to put "+UA" is the textbox next to the drop down on the
upper left of the program. This should also be to the left of the "POV-Win"
toolbar button.
