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 8):
The method as set forth in  claim 7 , further including the steps of: determining a plurality of signatures for a plurality of safety sounds;\n storing the plurality of safety sounds and the plurality of signatures in a safety sound memory unit of a digital signal processor of a system on a chip; and storing the plurality of signatures in a head unit memory unit of a head unit controller in communication with a vehicle communication bus and coupled to the system on a chip.
