NAME

       xanalogtv - Simulate reception on an old analog TV set

SYNOPSIS

       xanalogtv  [-display  host:display.screen]  [-window]  [-root] [-install] [-visual visual]
       [-cycle] [-no-cycle] [-fps]

DESCRIPTION

       xanalogtv shows a simulation of an old TV set showing test patterns and any  other  images
       you  have  provided.  It  reproduces  a  wide  range of TV reception bummage: snow, bloom,
       ghosting, and loss of vertical and horizontal sync. It also simulates the TV  warming  up.
       It  will cycle through 12 channels, some with images you give it, and some with color bars
       or nothing but static.

       The images that it uses will be grabbed from the portion  of  the  screen  underlying  the
       window,  or  from the system's video input, or from a random file on disk, as indicated by
       the  grabDesktopImages,   grabVideoFrames,   and   chooseRandomImages   options   in   the
       ~/.xscreensaver  file;  see  xscreensaver-demo(1)  for  more details. It looks best with a
       video input or your digital photo collection.
