Automatic remote control system for the output time of television frame synchronizing pulses

Conclusions

• 1. The use of a telephone line connecting the transmitting television center with the control point of the State Time and Frequency Service as a control channel makes it possible to match the output time of one of the frame synchronizing pulses (the edge of the first notch or the second pulse transmitted in the composite television signal) with the output time of the second pulses from a state standard clock to an error of ± 0.2μsec.

• 2. The proposed design of a system to control the output time of frame synchronizing pulses makes it possible for users located in the reception area of the Moscow television transmitting center as well as users who receive the All-Union television broadcasting program over intercity and international cable and radio relay links to tie in local clocks without a reciprocal exchange of information with the central control point regarding the measured results.
