Video Distribution Facilities for Television Transmission

This paper describes the Bell System's plans for furnishing network and local video facilities. The Telephone Company is now using broad-band coaxial cable and microwave radio systems to provide regular message telephone service on a number of principal intercity routes throughout the nation. These facilities can be used to provide television transmission channels when properly equipped. Video service between Washington, D. C., New York, and Boston over these two types of facilities has been demonstrated. New facilities are rapidly being extended. Local video channels for pickup and metropolitan-area networks are provided by ordinary paper-insulated cable pairs, special shielded polyethylene-insulated pairs, by microwave radio systems, or by combinations of these systems. Amplifier and equalizing arrangements for providing wide-band transmission over these facilities are described. Present Bell System views of the availability of microwave and coaxial cable facilities on the principal routes, types of circuits, bandwidths, bridging and terminating arrangements, and general information concerning the provision of television circuits are covered.
