Data inserter: AUDIO TAG

The analog or AES signal goes through the AUDIO TAG equipment which is located in the studio or in the post-production department of a radio or TV station. This equipment places the inaudible code into the audio. The user can define the code to be inserted (based on 24 usable bits). Special software allows tthe user to check the quality and number of inserted codes. The tag does not affect the audio quality and it supports wave format, MPEG2, MPEG3 and two consecutive compressions.

Data reader and RF monitoring

The Multiband receiver system allows the reading of inserted codes and basic RF parameters such as RF carrier and audio modulation (alarm thresholds can be defined by the user) In real time, it reads the hidden data in the audio signal and stores the inaudible messages in specific files. This product is modular: up to 4 receivers can be installed and operated at the same time. Three different types of modules can be used: FM, AM and TV. The managing server can load and classify in a database all information relative to the watermarking: codes and audio files. Audio connectors can be installed on a specialized panel (1U).
