摘要： PURPOSE: To inhibit the display of test signals on a screen even when the deflection position of the screen is changed by synchronizing the detection signals of the white level of the test signals to deflection position signals for determining the deflection position and letting them follow up the fluctuation of the deflection position. CONSTITUTION: A multivibrator 7 prepares the test signals 6 of a TTL level and white and black level detection pulses 19 and 18 with the deflection position signals (pulses) 17 as reference. A test signal superimposing circuit 2 superimposes the test signals 6 synchronized with the deflection position pulses on input video signals. The test signals 6 are provided with the white level detection pulses 19 within the pulse width of the test signals and the black level detection pulses 18 follow immediate after the test signals 6. Thus, since timewise relation of the deflection position signals 17, the white level detection pulses 19 and the black level detection pulses 18 is fixed at all times, even when the deflection position of the screen is shifted, the test signals 6 are not displayed on the screen.

摘要： PURPOSE:To transmit a key signal compatible with a different format transmission system of a same CATV network by extracting a scramble release key signal from a scrambled signal and adding the key signal to other signal. CONSTITUTION:A scrambled audio signal is detected by a BPF 14 and an AM detector 15, and a 7-bit data pulse (DB) is stored in a register 20 controlled by a timing detection circuit 19 outputting a timing signal synchronously with a vertical period via a gate circuit 17 controlled by a V signal detection circuit 18. A 4-bit DB corresponding to a scramble release key signal in the DB is fed to an address generating circuit 21. Then a ROM 23 is accessed by an output address of the circuit 21 and the scramble release key signal is extracted and the video signal not scrambled and the scramble release key signal are superimposed, then the key signal compatible with a different format transmission system of a same CATV network is sent.

摘要： PURPOSE:To obtain a scramble system and a CATV system with high security by superimposing and inserting burst synchronizing width information and a KEY data representing the scramble mode or the like for the vertical blanking period of a television signal. CONSTITUTION:Burst synchronizing width information and KEY data are inserted and the resulting data is sent for the vertical blanking period of a television signal. Thus, even When picture information is illegally descrambled, a key signal is only the synchronizing width information and the KEY data, and the synchronizing width information is a signal for a video band frequency, then it is not easily and clearly separated from other video picture information. As a result, no pseudo synchronizing signal is generated and the synchronizing signal is not reproduced and illegal descrambling is disabled. Moreover, even when the KEY signal is inserted for the vertical blanking period, the reproduction of the horizontal and vertical synchronizing signal is disabled from the signal only. Thus, the scramble system and CATV system with high security are realized.

摘要： PROBLEM TO BE SOLVED: To obtain a display device in which discharge is stabilized and power is saved and to obtain a driving method therefor. SOLUTION: A setup period is provided prior to first subfields SF1 of respective fields. In the setup period, vertical synchronizing setup pulses VS are simultaneously applied to plural scanning electrodes 12. Discharge is generated between an address electrode 11 and the scanning electrode 12 by the rising of the vertical synchronizing setup pulse VS and positive wall charges are accumulated on the side of the address electrode 11. In an address period, a write pulse Pw and a write pulse Pwa are applied respectively to the scanning electrode 12 and the address electrode 11. Since the positive wall charges are accumulated on the electrode 11, an effective voltage to be applied between the electrode 11 and the electrode 12 becomes higher.
