    From the Paris expo,
  • 0:48 - 0:50
    Piero Angela tells us
    about a technical novelty...
  • 0:50 - 0:53
    ...that will be extraordinarily
    important for television.
  • 0:56 - 0:57
    A revolutionary procedure...
  • 0:57 - 1:01
    ...in the field of
    image reproduction is displayed...
  • 1:01 - 1:03
    ...at the American pavilion
    at the Paris expo.
  • 1:03 - 1:06
    For the first time
    since photography exists.
  • 1:06 - 1:07
    since cinema exists,
  • 1:07 - 1:10
    it won't be necessary
    to use film tape...
  • 1:10 - 1:11
    ...to reproduce an image,
  • 1:11 - 1:14
    but a magnetic tape will suffice:
  • 1:14 - 1:17
    the videotape,
    the television recorder.
  • 1:17 - 1:18
    Here's how it works.
  • 1:18 - 1:21
    Here is a normal camera,
  • 1:21 - 1:25
    which sends the picture
    to the van outside,
  • 1:26 - 1:29
    van normally equipped
    for television filming.
  • 1:29 - 1:33
    And down here is the magnetic recorder.
  • 1:34 - 1:36
    Look at the spinning reels:
  • 1:36 - 1:40
    the working principle is exactly
    the same as a voice recorder.
  • 1:41 - 1:43
    The speed is the same,
    15 inches per second.
  • 1:44 - 1:45
    The maneuvers are the same too:
  • 1:45 - 1:48
    a series of buttons to stop the tape,
  • 1:48 - 1:52
    rewind it, inserting or removing
    the recording at will.
  • 1:52 - 1:55
    The tape is simply taller,
    it's 5 centimeters tall.
  • 1:56 - 1:58
    The upper part records sound,
  • 1:58 - 1:59
    the lower part the image.
  • 2:00 - 2:02
    How does it record the picture?
  • 2:02 - 2:04
    Exactly as with the sound.
  • 2:04 - 2:07
    Lights and shadows are translated
    into electric impulses,
  • 2:07 - 2:08
    and a magnetic head,
  • 2:09 - 2:10
    above the recorder,
  • 2:10 - 2:11
    imprints on the tape.
  • 2:12 - 2:15
  • 2:16 - 2:18
  • 2:18 - 2:23
  • 2:23 - 2:25
  • 2:26 - 2:27
