Television Raster

Television Raster

 

the set of lines into which a transmitted image is translated as the image is read from the target of a television camera tube, or the set of lines of the reproduced image as it is synthesized on the screen of a kinescope; the raster constitutes the television frame. In broadcasting television, the raster has a rectangular shape. Its format, that is, the ratio of the width to the height, and the format of the frame are usually equal to 4:3. In the absence of a video signal or when the video signal is constant, a television raster on a kinescope screen is seen as a uniformly luminous rectangle.

Rauschenberg in general, in his ample thinking about painting and print, seems to lie in Guyton's history, while a work in which black is broken up by lines of white may recall the Frank Stella of the late 1950s--but also the television raster and the computer monitor.
