Abstract
Several mitigation circuits are disclosed. An audio mitigation circuit includes an audio mitigation control module configured to read a unique tone identification embedded in a digital audio signal to identify a digital audio tone. A video mitigation circuit confirms video to be displayed by a user interface. Another audio mitigation circuit is configured to process super-audible tones in an audio signal to confirm an audio asset. The disclosure also describes various methods associated with the mitigation circuits.

An audio circuit, comprising:
- a processor configured to generate a digital audio signal, wherein the audio signal comprises audio data bits inserted on a rising edge of a clock signal and additional data bits inserted on a falling edge of the clock signal, wherein the audio data bits on the rising edge represent a digital audio tone and the additional data bits inserted on the falling edge represent a unique tone identification of the audio data bits on the rising edge;
- a digital-to-analog converter configured to:
- receive the digital audio signal;
- convert the audio data bits inserted on the rising edge;
- and
- ignore the additional data bits on the falling edge;
- an audio mitigation control module configured to:
- receive the digital audio signal;
- read the additional data bits on the falling edge;
- and
- confirm that the audio data bits inserted on the rising edge represent a correct digital audio tone based on the unique tone identification.
