Telephone Picture Transmission

The picture transmission system which is now in daily commercial operation over the lines of the Bell System is to be distinguished from earlier efforts toward the same end by two features: First, the pictures as received are completely commercial in their character; that is, they are immediately available for all sorts of technical uses, for which they are in fact practically indistinguishable from original photographs. Second, the system is, unlike earlier experimental systems, so worked out that it utilizes without change the existing telephone channels, whether these be wire or radio. The distance to which pictures may be sent is limited only by the distances over which commercial telphone service is available
