In cable-television systems distributing separate programmes, the individual channels can be allocated from the system centre by means of controllable television transposers installed in intermediate stations close to the subscribers, which transpose the desired programme, selected by frequency, into particular output channels extended to the subscriber. Because such controllable transposers are not available on the market, conversion attachments intended for domestic use and obtainable in the United States have been examined for their suitability for the above-mentioned purpose. In order to make remote control possible, a digital electronic-control device has been developed for the transposers which are themselves only manually adjustable.
