摘要: A television system employing the sequential scanning system wherein picture information obtained by sequential scanning at a scanning frequency twice that of the standard system in separated into the first field information consisting of odd-numbered lines and the second field information consisting of even-numbered lines, and the separated field informations are stored in respective memory devices. The first and second field informations stored in the memory devices are transmitted separately by a transmitter. The first and second field informations received by the reception system are stored in separate memory devices. The first and second field informations are read out from the memory devices in the order of the odd-numbered line and then the even-numbered line at a speed twice the writing speed, and the read-out line information is displayed on a display device which scans sequentially the screen at a scanning frequency twice that of the standard system.

摘要: A vertical deflection circuit of the negative feedback type wherein a feedback signal, being generated at a terminal of a deflection current detector resistance connected in series with a vertical deflection yoke, is connected to negative feedback amplifier which guides the output of a sawtooth wave generating circuit through a third order distortion wave generating circuit. The third order distortion wave generating circuit imparts third order distortion of positive polarity to said feedback signals, so that third order distortion of negative polarity is imparted to the current of said deflection yoke, and whereby the third order distortion is compensated and extinguished on the CRT display.
