Abstract: 1510917 Priority circuit CINCINNATI MILACRON Inc 27 Oct 1976 [28 Oct 1975] 44680/76 Heading G4A Priority circuit has a flip-flop 40, 42 for each of several interrupt signals INTI-N of different priority, an encoder 58 generating a code E1-E4 indicative of the highest priority active interrupt signal, and a last-in-first-out memory 60, the code E1-E4 being stored in the memory only when it is of the same or higher priority than the current output M1-M4 of the memory, i.e. the code last stored. Whenever the last stored interrupt, identified by the code M1-M4 supplied by the memory 60, has been serviced by processor 10 a reset signal 86 actuates up/down counter 62 to access the next stored code. Comparator 68 compares this code M1-M4 with the code E1-E4 supplied by encoder 58 and actuates counter 62 to store the code E1-E4, and therefore present it to the processor for servicing, only if it is of the same or higher priority than code M1-M4, the flip-flop 40, 42 corresponding to the newly stored code being reset by reset circuit 48 in response to an acknowledgement signal 76 supplied by the processor. Where the code E1-E4 has lower priority than that M1-M4 presented by the memory the processor continues to process the interrupt corresponding to the code M1-M4, the new interrupt E1-E4 being held in the flip-flops until it has the highest priority.

In a pay television and audience survey system, a control station transmits a sequence of interrogation signals to subscribers, each interrogation signal being unique to a particular subscriber and comprising for example a combination of three frequencies selected from a larger number of frequencies, and each subscriber's receiver includes means responsive to its particular interrogation signal for returning a signal indicative of the acknowledgement of a prescribed programme charge by the viewer and of the programme corresponding thereto. The receiver is disabled from receiving the television signals until the charge has been acknowledged, e.g. by the insertion of the correct money in a coin box or by the operation of a credit switch. The viewers are informed of the programme charges by means of an audio signal transmitted from the control station and also by an indicator controlled by a train of coded pulses transmitted from the control station. The receiver response to interrogation may be in the form of one of a number of discrete frequencies corresponding to the programmes available. The control station includes means for distinguishing between the various response signals and for counting the different responses for audience survey purposes. Each response signal also gates the corresponding coded subscriber identity to a magnetic or punched, tape recorder, the date, time and programme charges also being recorded on the tape once in each interrogation cycle.
