The invention relates to automation and computing and can be used in devices designed to display information on the screen of a cathode ray tube (CRT).

The aim of the invention is to improve the speed of the device.

Fig. 1 is a block diagram of a device for outputting information; FIG. 2 shows timing diagrams of device clock pulses.

The device (FIG. 1) contains the first trigger 1, the generator 2 clock pulses, the element NOT 3, the first counter 4, the first element AND 5, the second element OR 6, the fifth element AND 7, the sixth element AND 8, the second element 9 of the comparison, the first Comparison element 10, second counter 11, third element OR 12, fourth element ШШ 13, seventh element И 14, second element И 15, first decoder 16, five counter 17, five element OR 18,

The composition, purpose and position of the links are described in the table.

The generator is a series-connected pulse generator, a pulse counter, and an encoder for a series of sync pulses. 3 Counter 4 contains the addresses of the location of the label on the screen of the video monitoring unit (BKB) 20 and is controlled by the signals arriving on the bus 34 from the editing unit external to this device. Counter 4 is divided into two halves (the line number counter and the address counter of the familiarity inside the line), each of which has its inputs +1 and -1, as well as a reset input. Signals to these inputs are fed through bus 38. Scoring 11 contains the address of the familiarity inside the current line when displaying information on the BKB 20 screen, counter 17 contains the current number. lines. The contents of counters 11 and 17 determine the address of familiarity on the screen of the BCB 20. Counter 21 sets the delay in outputting information on the screen of BCB 20 by the time of the return path of the beam. Counter 25 sets the delay in outputting information to the BKB 20 screen at the frame retraction time over the frame, and during the forward path of the beam per frame it counts the number of output lines of television lines. Trigger 1 blocks the passage of pulses to the input +1 of the counter 11 during the return path of the beam along the line. The trigger 1 is set by the signal on the bus 35 at the moment of the beginning of the forward path of the beam, when the trigger 1 is installed, the pulses start to enter the +1 of the counter 11. Trigger 1 is reset by a signal on bus 36 when decoder 16 interprets the code for the end of the body of the visitor string. The trigger 27 stores the forward run indication on the line and is set by a signal on bus 71 when counter 21 counts to the end of the return stroke on the line, and resets T like trigger 1 by a signal on bus 36. Bus 74 is the forward output of trigger 27, and the bus 41 - inverse output. The trigger 31 stores the sign of the forward course of the frame. Trigger 31 is reset by a signal on bus 76, when decoder 22 interprets the code of the last line in a frame on bus 47 and is set by a signal on bus 66 when decoder 28 advances the code of the end of the reverse stroke on the frame on bus 72. The device operates as follows. 774 Each time a frame sync pulse arrives, counters 17 and 25 are reset. Counter 25 begins counting the frame retraction time. As soon as the decoder 28 interprets the end-of-turn code for the frame, it clears counter 25 by a signal on bus 66 and sets trigger 31. After trigger 31 is set, the pulse strings on the bus 43 are received. When the horizontal sync pulse arrives, bus 63 clears counter 21 and one is added to the counter 25. Counter 21 starts counting the return stroke time on the line. At the end of the return stroke, a trigger setup signal 27 is generated on the line 71. After the latter is installed, the reset signal from the counter 11 is removed via the bus 41. If the trigger 31 is set at the moment the trigger 27 is installed, the trigger 35 is set by the signal 35, the signal passes outputting the mark to the screen of the VKB 20 via bus 64 and passing a signal indicating that the contents of counter 4 are equal to the contents of counters 11 and 17 on bus 79. After the installation of trigger 1, the passage of pulses to the input +1 of counter 11 through bus 51 is allowed. Bus 79 enters into an editing unit, and allows the cycle start editing (editing mode) .. The apparatus performs the following main functions: display information on the screen 20, BCB, acceleration editing start and editing. In the editing mode, the control of the counters 4, 11 and 17 is carried out only by signals from the editing unit. Counter 11 is clocked by a series of clock pulses on bus 40, Counter 17 when outputting information to the screen of BKB 20 is clocked by pulses on bus 43, but when the editing start is accelerated, a series of clock pulses from 40 begins to accelerate editing. 20 is interrupted by a low signal on bus 44 from input -1-1 of counter 17, the signal of bus 43 is turned off as well. a high signal level on bus 45 connects to this input a series of clock pulses of bus 40 (the signal on bus 45 is inverse with respect to the signal on bus 44). The signals from triggers 19 and 29, which are set at the moment the editing start is started, reset the counters 1 through bus 42 and 17 via bus 56. Immediately after the reset of counter 17, the trigger 29 is also reset. This clears the reset signal from counter 17 through bus 56 and the latter starts counting pulses arriving on bus 40. As soon as the contents of counter 17 become equal to the line number of the characters in which the label is located, the low level on the bus 46 of the series of clock bus 40 disconnects from the +1 input of counter 17 and the line count stops. At this moment, the trigger 19 is reset and removes the reset signal.

From counter 11 (via bus 42), then counter 11 starts counting. As soon as the latter counts to the familiar place of the line in which the label is located, the edit start enable signal is sent to the bus 79.

Using acceleration of editing starts up to ten times faster device performance. Higher speed is achieved by introducing new

functions of accelerating the start of editing, which reduces the number of familiarities on the WKB screen that need to be counted by the address counter of the displayed character before it reaches the label address. The mark on the screen moves without flicker visible by the operator, which reduces operator fatigue in the process of entering and outputting information.
