If a vector exceeds the size of a segment, it will be pre-divided in a computer into microvectors, each of which corresponds to a specific segment,. From computer information on micro vectors. is written to memory block 5. With the proposed device it is possible to display, in each segment, only one microvector connecting any two points in a segment. If two or more vectors pass through a segment, then the appropriate number of devices must be used to display it. One device allows displaying on the screen the number of microvectors corresponding to the number of segments of the television raster. During a macro string corresponding to one horizontal row of segments, the position counter by coordinate Y 1 counts the pulses corresponding to the frequency of the television lines and coming from the clock generator 16. When switching to a new clock, the pulse count starts first, from the output of the clock generator 16 during each sweep television. the rows at the position counter along the X-13 coordinate receive pulses (CIs) with a frequency corresponding to the positions along the X-coordinate, Counter 13 is turned on at the beginning of each segment and reset to the zero state at the end of each segment. The number of hyvzdis on the X coordinate corresponding to the segment is decrypted using the decoder 24.

rewrites from memory block 7 for oc-control block 9 and closes the output of the sparse segment with the following vector data; 1. The code of the coordinate Y of the initial point of the vector. U0, which is recorded in the counter 20 positions along the coordinate Y, corresponding to the vector. . 2. Coordinate code At the end point of the vector Y, which is written to the coordinate register of the code At the end point of the vector 4. The starting point of any vector is the point with the smaller coordinate Y, since the sweep of the television lines goes from the top and any vector is reproduced from top to bottom. 3.

The code of the X coordinate of the initial current of the vector XQ that is written adder 7 and register 8. The code from the output of the position counter along the Y coordinate 1 (VCTP) is fed to comparison blocks 2, 3, 17 and 18. On BTOpbie the inputs of the comparison blocks 2 and 17 are fed a code from the counter output 20 positions along the Y coordinate corresponding to vector (initially this code is equal to Y - the coordinate code Y of the initial m vector glasses). The second inputs of Comparative Units 3 and 18 are fed with a code Y at the end point of the vector. Comparison units form one of the three signal variants greater, equal or less. These signals arrive at block 19. At the beginning of the segment, when an alternate television line is unfolded, all the output signals of comparison blocks 2 and 17 are interrogated by the signal b in block 19. Herewith: Ul-r1 Wo. Avgr- three situations are possible: or. In: whether, then from the output of the logical / tore block 19 the signal will go to the control pen-9 block and stop the flow of signals b. Thus, until the scan of the TV lines reaches the beginning of the vector, the device melts. If V (;-( p Vo, then the output of block 19 is a signal which, for signals b, At the end of the sweep of this segment, the signal of the beginning of the segment from the output of the block, delay 25, rewrites the code (XQ ± X) from adder 7 c. register 22 and code x from register 8 to register 21 to display these values., the rank when scanning the line in the next segment. The same signal records the next data from the block (memory 5 to the input blocks. white line intersects the vector, i.e., VC-IP 0, then the signal b in block 19 interrogates the outputs of the blocks of comparison 3 and 18. EcliVc p Vv, then block 19 produces signal, which is fed to the input of the counter - the positions on the Y coordinate corresponding to the vector 2% and adds one to the code U. i.e., the device USTR Uo +1 ... forms at the same time as the second output of the block As the signal 19 rewrites the code from register 6 into the adder 7. In this case, a code () is generated in the adder 7. In this case, no signal is generated at the third output of the block. 19, which blocks the flow of signals. This signal comes from the second output block, control 9 on synchronous inputs of the register of codes at the coordinate X 8 and rewrites into it od of starschih bit adder rows 7. In this code in an adder 7 is not changed. The signal b from the first output of the control unit 9 skov comes to the block 19 for interrogation of the steps of the comparison blocks Now the codes of the device and the PP + 1 are compared. US-TP PP + i then the signals on the second and third outputs of the block are formed. 19, an increment of + AX is added to the code (XQ + X) in the adder 7 and the device stops working. If US-T UO + 1, signals are generated on the first and second outputs of block 19, another one is added to the counter 20 the unit, and the code in the adder 7 is once again added to the increment of 1+, and so on, as long as V -g | and the operation of the device stops. If U. p Y, then the device does not work, since the expandable line passes below the end of the vector, and in this case, no mapping is required. The transition to the next current segment on the screen displays those values that were calculated in the previous segment. The codes from the adder 7 and the register .8 are rewritten into registers 21 and 22, and the trigger 23 remembers the increment sign l, X. The code in register 21 is different from the code in register 22. By the increment value of the coordinate X (± AX). When the lines are scanned in a block: the existing segment code from the outputs of the bits of the position counter along the X 13 coordinate goes to comparison blocks 10 and 11, the second inputs of which receive codes from the outputs of the bits of registers 21 and 22. When the codes of the comparison blocks are equal, the signals that are sent to the illumination signal shaping unit 12. In f BHCHMOcf and from the increment sign of the X coordinate, the illuminator 12 illuminates the strobe either from the X-, -XX coordinate to X, or from X (TO X, + LH. Shaper 12 output goes through video gain The telescope 14 is displayed on the television receiver 14, where it is displayed in the form of a line portion illumination.
