||TV pictures from a record!: New!
A new system, called "Phonovid" plays still TV pictures as well as sound
from a phonograph record. Up to 400 pictures and 40 minutes of sound can
be recorded on both sides of a 12 inch long playing record. Heart of the
system is a slow to fast scan converter which takes the signals from the
phono pickup and converts them into a TV display. An electronic storage
tube stores the picture line by line and, when the picture is complete,
reads it out to the receiver. Two such storage tubes are used. One is repeatedly
reading out a picture while the other tube is constructing the next one
from the video information in the grooves of the recording. The storage
tubes alternately read out a picture every six seconds. Both the turntable
and the television set are entirely standard. The equipment, in a laboratory
prototype form, was demonstrated recently by Westinghouse. The company
foresees the system for classroom instruction, industrial and military
training, vocational education and sales presentations. Text and photo:
