Broadcasting system transmitting information as masked audio signal, divides spectrum of primary signal into bands and sub-bands for transmission of secondary signal |
摘要 |
The audio transmission spectrum for the primary signal, is divided into n bands. Within each band a sub-band of adequate bandwidth is allocated for the secondary signal. The secondary signal is added to the primary signal, exploiting the principles of acoustic masking. Both signals are transmitted together. |
