ABSTRACT:
A video projection system for enlarging and projecting the image or picture from a television receiver includes a mounting system including a cradle having a frame for securing to the television receiver and including support members for supporting the television receiver for pivoting about a horizontal axis with the cradle mounted on a base member for pivotal movement about a vertical axis. A projector is mounted on the face of the television receiver and includes a mirror and enlarging lens such that a proper image is projected onto a front viewing screen when the television is turned either face up or face down with the bottom of the receiver toward the screen when face up and the top of the receiver toward the screen when face down for front projection. For rear projection, a mirror is positioned between the enlarging lens and the back projecting screen with the television receiver turned face down and covered by the projection box.
