We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
Tale of the Tape A REVOLUTION of sorts is brew¬ ing up in the television indus¬ try, and, as is frequently the case, that man—Brigadier General David Sarnoff—has his hand in it. The General, head man at Radio Corporation of America, parent com¬ pany of NBC, was feted a few years back for his 45 years of leadership in the radio and television industry. As usual, the General had no time to look back. Instead he asked that his RCA scientists get to work on three pet projects that he had been ponder¬ ing. The three were: a video tape re¬ corder, an inexpensive electronic air conditioner and a true amplifier of light, and they were to be completed for his 50th anniversary in 1956. Already Request Number One is almost nailed down. And that’s what the revolution is about. If you’ve ever played around with one of those magnetic tape sound re¬ corders, then you have some idea of TV tape. It works on much the same principle as sound tape, seems just as simple to the layman, but technically speaking, is far more complicated. The immediate benefits of this de¬ velopment will be as “a practical, low-cost solution to program record¬ ing, immediate playback and rapid distribution.” It should prove far cheaper than kinescoping, because while raw tape is more expensive than film, it has no processing costs between recording and playback. More important, it can be electrically “wiped off” and reused. As for color TV, the cost of putting a color show on tape is estimated at about five percent of that of film. 18
