TELEVISION SYSTEM HAVING ADDITIONAL INFORMATION TRANSMISSION BELONGING TO TELEVISION FRAME SCANNING DIRECTION, GENERATOR AND INFORMATION RECEIVER SUITABLE FOR TELEVISION SYSTEM

摘要

IN THE INFORMATION GENERATOR 1, A VIDEO SIGNAL SOURCE 6 IS DIRECTLY COUPLED AND THROUGH A LINE DELAY DEVICE FROM THE SOURCE 9 TO A SUBTRACTION CIRCUIT 12 FOLLOWED OF A CARRIER WAVE MODULATOR AUXILIARY 19. AN ADDITIONER CIRCUIT 32 IS COUPLED AT THE OUTPUT OF THE MODULATOR 19 AND THE SOURCE 6, POSSIBLY THROUGH THE DELAY DEVICE 9. THE DIFFERENCE INFORMATION OBTAINED IS FREQUENTLY TRANSMITTED FREQUENTLY WITH THE VIDEO INFORMATION INFORMATION RECEIVER 5. THIS HAS A FILTERING CIRCUIT 54 FOR INFORMATION SEPARATION. The MODULATED AUXILIARY CARRIER WAVE GOES THROUGH A DEMODULATOR 58 TO A SUPERPOSITION CIRCUIT 66 WHICH IS ALSO PROVIDED WITH THE VIDEO INFORMATION, ALSO HAS A SWITCHING CIRCUIT 73 WHICH IS ALSO CONNECTED WITH THE OVERLAY CIRCUIT 66 BY THE INTERMEDIARY OF A SOURCE LINE DELAY DEVICE 70. ALTERNATIVELY, DURING A SOURCE LINE PERIOD, THE MERGED INFORMATION IS TRANSMITTED. / P P APPLICATION: ENHANCING THE DEFINITION DURING REPRODUCTION IN FRAME SCAN DIRECTION.
