Description

The invention relates to computing technology n can be used as FsiieiiiHe.rc ycTpcs: tsi; g-ryovy computational / ifti: i: ti for displaying game characters dongy graphic information

A device for displaying symbolic and graphical information containing OR elements, a timing unit for control connected to the reg are known: shear countries, AND elements and sign generators and graphite elements connected to a cathode ray tube, L1 television scanner unit.

The disadvantage is that the known display device contains generators of symbols and graphic elements and allows displaying a limited circle of information symbols and their combinations, since a certain scheme is required for each information symbol. Therefore, an increase in the characters of the displayed information entails a significant increase in hardware costs, an increase in size.

A device for displaying information on the screen of a television receiver, containing a control unit, the first and second outputs of which are connected to the television scanner inputs of the television receiver, is known, the input of the control unit is connected to the first input of the first KONMyTaTopa, the second input of which is connected to the output of the receiving register , the fourth output of the control unit is connected to the first input of the backlight pulse shaping unit, the second input of which is connected to the output of the first comm card, the fifth output of the control unit It is connected to the first input of the second commutator, the second inlet of which is connected to the output of the illumination unit UMiiyjifcsov, the sixth output of the control unit is connected to the first input of the first shift register, the second input of which is connected to the first output / output of the second switch f2j,

The disadvantage is that the said device allows displaying various types of information without significant hardware costs.

information from an external source (not shown) through the receiving register 4, the first switch 3, block 5, the second switch 6 enters; even (odd) bits for the first shift register 7 and odd (even) bits for the second shift register 8. The shift input of the register 7 to the input of one element AND element 9 2I-OR is supplied to the clock pulses from the control unit 2 Through the elements 10 NOT to the shift input of the register 8 and to the third input of the element 9 2I-OR the clock pulses of reverse polarity are supplied. The clock pulses shift the information in registers 7 and 8. If there is an input at the input of element 9 2I-OR pulses, the resulting output is obtained. double frequency signal. When applying to the receiver 1 synchronizing pulses from the control unit 2, the frame and drain scanning is synchronized with the clock pulses, and the pulses from the output of element 9 2I-OR, the points to the receiver 1 are displayed at twice the frequency in accordance with the code information at the input of the receiving register 4. With the same scanning frequency of the electron beam, this allows the beam to be illuminated when it is moved to half the discrete value of its thickness and, consequently, improves the image quality., J

Introducing the second shift register 8, element 9 2I-OR element 10 does NOT improve the image quality on the receiver screen% by increasing the frequency of the video pulses without increasing the frequency of the clock generator.
