Abstract

870,064. Distributing music &c. RANK ORGANISATION Ltd. Jan. 5, 1960 [Jan. 6, 1959], No. 482/59. Drawings to Specification. Class 40 (4). In a wired distribution system for sound and television programmes which is located within the service area of a broadcast television transmitter which radiates vision signals amplitude modulated on a carrier to occupy a frequency band within the bandwidth of the transmission channels of the system, the signals from the local television transmitter are converted to occupy in the system a frequency band other than that in which they are radiated, and at least one additional carrier having a centre frequency within the frequency band of the radiated vision signals is transmitted over the system, each such additional carrier being modulated in frequency by a signal other than the radiated vision signals. As described, three such additional carriers are transmitted, modulated by respective sound programmes, and the spaces between them are used to transmit signals for the control of coin-freed switching devices at subscriber stations in respect of prepayment programme items.
