Abstract:
A system for inserting auxiliary data into an audio channel that carries an audio signal includes a modulator configured to convert an auxiliary data signal into a modulated auxiliary data signal that has a passband within the audio channel's passband. The system for inserting auxiliary data into an audio channel that carries an audio signal further includes summing means configured to combine the modulated auxiliary data signal and the audio signal into a combination signal to be carried in the audio channel.
