摘要 |
FIELD: information transmission systems. SUBSTANCE: in compliance with method of transmission of additional discrete information in composition of full television signal line synchropulses are modulated on sending side in duration by signal of additional discrete information. Line synchropulse of standard duration corresponds in this case to zero signal of additional discrete information and synchropulse having duration half as short as that of standard one corresponds to one. Demodulation and reconstruction of initial additional information take place at receiving side. EFFECT: increased informational capacity of full television signal. 4 cl, 6 dwgi
