In the case of the Staxaofermaahema or the stereo color television system, the conditions are even more complicated. The systems in the Yeraucha stage use the current color television system to transmit a picture of the atereoakepiechen picture pair, but for the second picture the black-and-white technology. Sa are transmitted animal signals, three of them with a frequency band limited _{to 1 f 5 KHs.} A compatible signal is the luminance signal of one of the images of the steraoacoustic image pair in the high frequency area of this signal with the subcarrier frequency W ' 4.43 HHs, whereby the three signals of the color image (chrominance signals) are transmitted in coded form. For reception, two different picture tubes and stereo glasses with polarization filters are used. These systems have the disadvantage that they are too complicated and too expensive for most television viewers, although they are still forced to wear stereo glasses during reception.

At the exit of the picture tube one receives a sequence of different pulses} corresponding to the different densities of the Color filter ribbons. The peak value of the pulses corresponding to the completely transparent bands 5 is greater than for the other impulses. The pulse train goes through a preamplifier 21 and an intermediate amplifier 23 from where they are fed into a limit amplifier and at the same time to an electron switch controlled by the delay line is directed. The color selection for each element of the interwoven image is carried out by a selection device with pulses

One of the known systems is used for the automatic switching of the colors during the broadcast. So you get at the output of the limit amplifier square-wave pulses only for the transparent bands S of the stereochromatic filter, which are led to the delay line. The width of each ribbon is a quarter of the diameter of the sensing element as shown in FIG. In the time which is a quarter of the sampling time of a Corresponds to the picture element, the control pulse reaches the switch of the red channel E. The impulse opens the tube of the switch for a time that is also a quarter corresponds to the sampling time of an element, so that the red component of the signal enters the channel. The impulse then passes through the delay line after the same period of time, opens the switch of the green channel and in the same way also the third channel. In this

To control the position of the touch light beam or to automatically adjust the linearity, a grid 71 can be used, which consists of a multiple photodiode or a grid with semiconductors, the cells of which are connected in parallel or in series, which are located in the glass plate 66 on the back of the Additional device are attached. The signal bands S have the task of generating larger instantaneous values of the current during the scanning in the acceleration electrode of the picture tube, these pulses being used to determine the position of the scanning beam or to adjust the linearity. In some cases, the alimentation battery 72 and the load resistor 73 may be missing. Under the influence of the light beam that hits it, the currents generated by the photodiode pass through an amplifier 74 ^and oil is directed by the changeover switch 75, which is connected to the changeover switch 63, accelerating electrode of the picture tube

Cannot be used as a stereo color accessory, as shown, or as a simple color accessory ·. In the latter case, the lens grid and the second image of the stereo image pair in the broadcast are dispensed with. From the entire spectrum of picture frequencies that are received by the normal black and white television set, the frequencies of the color signals are taken with the help of selection filters, they are demodulated and then sent through an electronic switch to the control electrode of the picture tube, on whose screen 'the is fixed color filters red and blue green with horizontal bands in the colors _e the electron gun schiokt the signals grouped into lines or fields on the screen. By using the light-amplifying color filter, the correct position of the colors on the screen is achieved regardless of the change in position of the scanning beam, so that the color switch with its elements 7I to 74 must be optionally used by means of index signals.

If on some receivers the attachment of the color ^! filter on the screen of the picture tube causes difficulties because of the glass thickness of the screen, then the circuit can be implemented as an additional device with an independent picture tube, as shown in FIG. Here, the parb or stereo color filter is either permanently attached to the screen or built into it. Since the two picture tubes are used one after the other, the life of the black and white television is doubled.The additional device can be very small, since its dimensions depend on the picture tube used, or on the contrary, the Parb or stereo color filter can be al Large format screen
