Abstract

An addressable event display and control system for use with a clock controlled programmable memory employs an array of LED'"'"'s as event designators each of which signifies, when energized, a programmed event in the memory. A bank of seven dual LED'"'"'s, which is coupled to the memory, is selectively energizable to visually indicate a particular day of the week. When a particular day is selected, the array of designators for that day can be interrogated to determine which of the designators have been programmed for the particular day. Thereafter, a desired one of the designators can be selected to afford review of the program content of the event associated with that designator. The selected event designator is identified by a blinking visual signal. The time of day, a channel and a recording duration time are selectable to identify a particular event and that information is programmable into the memory for subsequent retrieval to control a video frequency recorder in accordance with such information.

Claims

1. An addressable event display and control system for use with a clock controlled programmable memory having the capability of storing a multitude of time related program events, which events are utilized, chronologically, for controlling a video frequency recorder, the content of each said event comprising a plurality of pieces of information, said event display and control system comprising:

an array of light-emitting devices coupled to the memory, each of said devices constituting an event designator and signifying, when energized, storage of a programmed event in the memory;

a bank of light-emitting day-of-the-week indicators also coupled to the memory, as well as to said array, and selectively energizable to visually identify a particular day;

means for selecting a particular one of said day indicators;

means responsive to selection of said particular day indicator for interrogating said array of event designators to ascertain which of said designators have been programmed for said particular day;

means for selecting a desired one of said event designators for said particular day to afford review of the program content of said selected event designator;

visual signaling means, responsive to said designator selecting means, for identifying said selected event designator;

programming means, including visual readout means, for selecting and visually displaying the time, channel and recording duration information that identifies an event to be associated with said selected event designator; and

means for entering said program information into the memory for subsequent retrieval upon said selected day to control the recorder.

2. An addressable event display and control system in accordance with claim 1 in which said array of light-emitting devices comprises a plurality of light-emitting diodes (LED'"'"'s) individually constituting one of said event designators.

3. An addressable event display and control system in accordance with claim 2 in which each of said LED'"'"'s comprises a dual section light-emitting diode and which further includes means for illuminating one section of said dual diode to signify storage of am AM program and for illuminating the other section of said dual diode to signify storage of a PM program.

4. An addressable event display and control system in accordance with claim 1 in which said bank of light-emitting day-of-the-week indicators comprises a plurality of light-emitting diodes (LED'"'"'s) individually constituting one of said day indicators.

5. An addressable event display and control system in accordance with claim 1 in which said means for interrogating said array of event designators comprises a READ counter:

scanning means for driving said counter; and

means for applying the output of said READ counter to a predetermined address in said memory.

6. An addressable event display and control system in accordance with claim 5 which further includes a WRITE counter;

a memory address preset circuit responsive to said means for selecting a particular one of said day indicators; and

means for coupling the output of said preset circuit to said WRITE counter and to said READ counter for conditioning said counters to count only within a preset block of addresses.

7. An addressable event display and control system in accordance with claim 1 which further includes a clock timer for controlling said means for selecting a particular one of said day indicators.

8. An addressable event display and control system in accordance with claim 1 which further includes means for causing said array of event designators and said visual readout means to blink at a predetermined rate to signify that the program content of said selected event designator is under review.

9. An addressable event display and control system in accordance with claim 1 which further includes means for selectively establishing said system in AUTOMATIC and PROGRAM modes.
