Abstract:
Audio and video systems for checking safety sounds and telltales are provided. The audio system includes a digital signal processor with a plurality of safety sounds and a plurality of signatures corresponding thereto. A head unit controller includes a signature and volume checker to identify an expected signature of the one of the safety sounds. The digital signal processor outputs a mixed audio stream and includes a lower bit inserter to replace lower bits of the mixed audio stream with replacement lower bits based on the signature and output a modified audio stream. A lower bit extractor separates and outputs the replacement lower bits and a remainder of the modified audio stream. An audio amplifier unit receives and outputs the remainder of the modified audio stream. The head unit controller rebuilds the signature, determines whether the signature matches the expected signature, and sends an acknowledgment accordingly.

Claim (Index 5):
The system as set forth in  claim 4 , wherein the head unit controller is further configured to transfer the one of the plurality of safety sounds to a steering wheel buzzer and request to mute the audio amplifier unit in response to at least one of the one of the plurality of signatures not matching the expected signature and the reconstructed volume of the meta data not matching the expected volume.
