NAME

       xanalogtv - Simulate reception on an old analog TV set


SYNOPSIS

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


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 hor-
       izontal  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 ran-
       dom  file  on  disk,  as  indicated by the grabDesktopImages, grabVide-
       oFrames, 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.
