DESCRIPTION

14       xanalogtv shows a simulation of an old TV set showing test patterns and
15       any other images you have provided. It reproduces a wide  range  of  TV
16       reception bummage: snow, bloom, ghosting, and loss of vertical and hor‐
17       izontal sync. It also simulates  the  TV  warming  up.  It  will  cycle
18       through  12 channels, some with images you give it, and some with color
19       bars or nothing but static.
20
21       The images that it uses will be grabbed from the portion of the  screen
22       underlying the window, or from the system's video input, or from a ran‐
23       dom file on disk, as  indicated  by  the  grabDesktopImages,  grabVide‐
24       oFrames,  and  chooseRandomImages  options in the ~/.xscreensaver file;
25       see xscreensaver-settings(1) for more details. It  looks  best  with  a
26       video input or your digital photo collection.
