In the earlier development of television technology, there were limitations the stability of the time base due to the use of o.ynchronisier ^ .eneratoren of the type mentioned are not considered more serious Considered disadvantage. In the further development of the Television technology, especially with the advent of color television broadcasting and which has television tape recorders (TTR) the poor quality due to time base errors caused by known synchronizing generators increasing attention found, especially because of the use of low frequency clock oscillators to output waveforms with time base errors leads. The nature of these lateral fundamental errors and their reduction using the inventive concept will be discussed in detail in the following description. First of all, it is sufficient to say that in today's television technology, especially in color television technology and, in the color television recording, an extremely accurate timing relationship between all of the sync generator outputs is necessary to ensure a high quality of color reproduction. .

The punk jump effect causes a Displacement of the black points of a certain sub-grid within the white areas of the image field of the previous one Rasters, so that the unwanted effect of a sonet occurring Interference in image reproduction is reduced.

The point jump effect is particularly important when reproducing black-and-white images on the basis of signals that include color information. 3 black and white sm? R ^r n: _- er k. ^: As is well known, they can reproduce the periodic interpole frequency transition between black-and-white functional representations of the 3.58 short-wave carrier signal, since there is no band-pass filtering that normally occurs in a color television receiver. Even a slight momentary fluctuation in the signal frequency necessarily results in a time base error, which results in a harmful interruption of the point jump pattern mentioned and a change in the repetition frequency of the horizontal synchronizing signal. This clearly shows the need for a very precise mutual temporal relationship.

As with synchronization generators, television tape recorders the two main causes of the time base errors. Today's technology for recording TV picture clips used on magnetic tapes for later playback one high-speed recording magnetic head in connection with the oxide layer of the magnetic tape, which in the longitudinal direction with comparatively slow feed rate continues. Usually the magnetic head comes with one on top of the magnetic layer applied to the high-frequency signal to be stored, which is generated by a composite television signal (composite Synchronization signal, mixed blanking signal and image information) is frequency modulated. To reproduce an undisturbed television picture, a high level of mechanical accuracy is essential and electromechanical control required within the device,

Because of a falling edge of the waveform 76 in FIG. 3 (the clock input waveform of 2, C475 MHz for the JK flip-flop 126), the states of the output terminals 140 and 142 are reversed. The output signal 142 of the lip stage 126 emits the waveform 78 (FIG. 3), which is connected to an input of the following circuit stage 128, which emits the output wave phone 8G.

This input waveform consists of a continuous 31.5 kHz signal corresponding to waveform 200 in FIG On the falling edge of waveform 200, the state in output terminal 264 of flip-flop 240 changes in accordance with waveform 202 in FIG. 5. When a falling edge occurs in waveform 202, the state of output terminals 266 and 268 of flip-flop 242 is reversed. This reversal of the state of flip-flop 242 delivers the waveform 204 * "The edges of the 'waveform 204 are differentiated in the resistance-capacitance circuit 262, whereupon the positive edges cause a presetting of the flip-flop 240 at the preset input 300 Four story: is modified into a three story in the same way as with the 1/65 divider 18 described above.

The 1/7 divider 22 and the 1/25 divider 24 according to FIGS 4 work in a similar way to the 1/65 divider 18 and the 1/3 divider 20. The flip-flops 244, 246 and 248 of the 1/7 divider 22 provide waveforms 206, 208 and 210 at output terminals 270, 274 and 278.

Appearance of a positive potential or an I ;; ⁵ .pul33s at one or more input connections 310 and 312, the output potential changes to a low value.

According to FIG. 9, two coder circuits 304 and 306 can be connected together to form a setting memory circuit. This circuit 320 has two input connections 316 and 318 as well as two output connections 322 and 324. Under normal operating conditions, as in the case of a 1 i? P stage described above, one of the two output connections 322 or 324 remains at a high potential and the other at a low potential. When one of the several input pulses is applied to the input connection 316, the output connection 322 is set to a low potential state and the output connection 324 is set to a high potential state. Conversely, when one or more positive pulses appear on input terminal 318, output terminal 324 places you low. That is to say, a low output state of the output connection 322 indicates that the last singing pulse or pulses arrived at the input connection 316. If you reverse the output states accordingly and the output terminal 324 _{V is} low, this shows

Each line form P08 and polarity reversal of waveform 206 are all input signals via terminals 274 and 272 in
the "or" circuit 458 is input, so that an i / ellenform 224 is obtained at the output terminal 546. At time 604 a positive edge occurs in the waveform 224 for the purpose of resetting the memory circuit 480 at terminal 546, so that the vertical synchronizing signal as a result of the high entry condition
cannot pass through the Ilichtoder circuit 454. The pulse generated by this transmission in a high voltage condition is coupled via the connection 544 to the high-voltage capacitance circuit 548, differentiated there and passed on to the memory circuit 482 as an input signal. As soon as the same is held, an input of the high-or-low circuit 452 is set to a positive voltage via the terminal 550, so that the output of the high-or-low circuit
452 comes into a low voltage state, which in turn acts on the no-OR circuit 450 via the connection 536 in such a way that the adjustment pulses can pass from the input 408 to the output connection 538.

Jieser Hachteil due in part to restrictions due to (ex use a low clock frequency, which is usually twice the Horizontalal & enkfrequenz. Partial has also contributed to this Kachteil that direct changeover in the selection of the clock pulses alternately During synchronization, it is normal to switch from the clock output to the output of a voltage-controlled generator that has essentially the same frequency as the clock generator, but with the additional possibility of a change

the output frequency. corresponding to a change in the input voltage.

The momentary shift at different points in time can therefore deliver pulse signals for the subsequent counter stages, which are alternately derived from the clock source and the voltage-controlled (oscillator) and are thus phase-shifted from one another by up to half the clock period.

The present invention utilizes a high frequency clock oscillator together with a high-frequency phase comparator eliminates these technical parts of the technology referred to With the entrainment and especially the release of the phase position in comparison to a distant oouelle.

An island description of the requirements of the /! for the invention and the prior art takes place with reference to FIGS. 11, 12 and 15. First, the mode of operation a known synchronizing drive circuit is explained with the aid of the block diagram of Jigur 12. This circuit j 26a generates the clock pulses in a clock generator in normal operation 28a. the same reach one via the connection 30a electronic switch 442, which corresponds to the position of the holder 444 is in .üurcb leave state. These clock pulses further reach a counter chain 16a via the connection 34a. A phase comparator 438 in FIG. 12 receives remote pulses at the input connection 440 so / ie at the input connection 418 local horizontal. impulses and supplies a control voltage that passes through a low-pass filter 434 applied to a voltage-controlled oscillator 436.

Yes, the switch position 446 at the output of the voltage-controlled Oscillator 436 is open at this point, owns the frequency of the voltage-controlled oscillator .436 only an imprecise phase relationship with the frequency of the local horizontal. pulses entering phase comparator 438 at input 418. In the release position, the pulse train that is in the Phase comparator 438 occurs at input 440, likewise none Phase oddr frequency coincidence with the signal waveform & öi Input 418, so that a control voltage via the low-pass filter 434 for frequency correction of the voltage controlled oscillator 436

receives. In this case, the oscillator 436 is corrected at this point false borrowed to an incorrect frequency value above or below the clock generator 28a, the size of the correction being limited only by the control range of the oscillator 436. Jenn then a synchronization is initiated by switching the switch 442 from the position 444 to the position 446, this wrong frequency via oscillator 436 is initially at the input of the S ^ .hlerkette 16a before the oscillator 436 is set to the correct * · orre.:turfrequenz This is why the duration is undesirable for a frequency!: orr.ektur; large _t so that a comparatively long period of raster interference results compared to the phase comparator 438 with the external raktimoulsen at the input 440, so that the control voltage of the CBRillator 436 corrects will be. As a result, the frequency of the input signal at connection 34a of sensor chain 16a is reordered in a period of time that depends on the time constant of filter 434 until a phase coincidence between the two input signals at inputs 440 and 418 of comparator 438 is reached. At the end of this period, the sympathy with synchronization is over. This termination of the kitting interval is completed by switching the switch 442 back to the position 444, so that the pulses from the oscillator 28a reach the selector chain 16a again.

Under these circumstances, there are various aspects for the Synchronisiermitnahmeschal device 26a in connection with low-frequency clock circuits when modified by the invention using a cooking frequency clock oscillator take place in the comparator 438, so that a compensation of a maximum phase shift of 31.8 m see is required when switching on the Kitnahmesohal- "ttiag 3.6a High-frequency clock signals aach er Brf.ln5lltief thus lead to the same amount "the
