1,066,931. Voting apparatus. BRITISH TELEMETER HOME VIEWING Ltd. March 26, 1964 [March 29, 1963; July 2, 1963], Nos. 12526/63 and 26246/63. Heading G4T. A television system incorporates voting apparatus including controls at each of a number of remote receivers which controls can be set in response to visual or aural interrogation signals received on the receiver, to indicate and record the opinion of the viewer. The control can consist of a single button which is pressed at an appropriate time or can consist of a row of buttons representing "yes," " no " and " don't know." The votes are recorded in the receiver e.g. on a magnetic tape which may be similar to that described in Specification 764,076 which is coin operated. The button is in a controlled circuit so that it cannot have effect unless the price has been paid, and the tape drive motor rotates a cam to close a holding circuit once a vote has been made. The question and answer are recorded in binary coded form on the tape. In a subscription system the votes are also recorded in a central recorder. If three voting buttons are used at each receiver each button produces a different modulation of. a carrier frequency. The button or buttons may prepare an answer which is transmitted when the receiver is next scanned.
