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.

for Video Signals The various parts of the video signals that carry a television picture through a coaxial cable travel at different speeds. When they leave the studio, they accurately represent the scene before the camera. But, like sprinters, some are faster than others and pull ahead in the "race" to the receiving point. Bell System technicians insure a "photo finish" by making intricate adjustments to coaxial cable facilities. Using special equipment, capable of measuring fractions of a millionth of a second, they slow down the faster frequencies so that all arrive at the same time. This is an interesting example of the great care the Bell System takes to insure high-quality transmission of television signals. It's only a small part of the total investment of money, equipment and personnel that is involved in making network television possible. Yet the cost of the service is low. The Telephone Company's total network charges average about 10 cents a mile for a half hour of program time. m BELL TELEPHONE SYSTEM PROVIDING TRANSMISSION CHANNEtS FOR INTERCITY RADIO AND TELEVISION BROADCASTING TODAY AND TOMORROW 11 AUGUST 1952 119
