Visit Visit our website “Television Line by Line” (1969) is a color illustrated, informational film based on the German language film Zeile Für Zeile (made in the Federal Republic of Germany) that details and demonstrates the basic principles of how pictures are formed on the TV screen. Distributed in the United States by the International Film Bureau Inc of Chicago, Illinois - the film was originally made by FWU Institut für Film und Bild in Wissenschaft und Unterricht in Grünwald, Germany. Opening credits (0:08). Illustration of retro, late 1960s movie camera and tv set (0:25). Illustration of photoelectric cell, meter, battery demonstrating photo effect, interaction between lights and the resistance of a semiconductor - light changes as the arrow on the meter oscillates (0:47). Illustration of light meter, moves around image on screen to detect rate of bright and dark light (1:43). Light meter records light on sepia-tone image of perhaps 1930s automobile in empty field (2:05). White curve appears under image, records deflection of the pointer the light intensity of the image (2:21). Paint brush follows the line to create abstract recreation of image, camera zooms out to reveal original photo made up of black and white stripes (2:41). Car from original image slowly movies, cloud of exhaust comes out of back pipe as it drives along rural tree-lined road (3:30). Illustrated 1960s television camera, perhaps emulating RCA TK60, interior of camera cube (3:43). Close-up of vidicon tube, interior anode and cathode (4:04). Breakdown of how lens of TV camera projects image, breakdown of screens inside the lens (4:25). Heated cathode at other end of vidicon tube, electrons bounce out of red square and form beam which can be moved according to magnetic field (5:34). Scanning pattern: electron beam moves in lines on screen according to the magnetic field (6:12). Close-up of signal plate with columns of , electron beam scans the column (6:43). Image of the vidicon tube and the electrical current flowing between the cathode condensers and the battery (7:25). Television signal: illustration of recording strip with white curve indicating light and dark areas (7:45). Profile of illustrated RCA TK60, white curve extends out of camera on bottom right corner (8:05). Antenna, white beams representing electromagnetic waves oscillate out of antenna strip (8:09). Waves overlaid receiver antenna (8:19). Cross hatch diagram of television tv picture cube - heated cathode releases electrons, beam formed that projects onto fluorescent screen (8:27). Incoming television signal fed to the control electrode (9:28). Magnetic field from electromagnets moves beam up and down along fluorescent screen (9:54). Front view of illustrated 1960s retro tv set, sepia-tone image of automobile slowly appears on screen (10:08). Illustration of NASA Telstar 1 satellite in space (10:40).
