A method and system for transmitting and receiving an audio signal over a video signal in a single cable. The method and system including receiving an analog video signal, the analog video signal comprising one or more rows of video data, an audio header, and one or more quantized audio data. The method includes detecting, the audio header in a blank interval of the analog video and determining a reference level of the audio header. The method and system include extracting, in response to detecting the audio header, the one or more quantized audio data and converting the one or more quantized audio data to an original value of audio data based on the reference level of the audio header. The method and system are configured for storing the one or more quantized audio data in the original value in a First-in-First-Out (FIFO) buffer, and reconstructing, utilizing the FIFO buffer, a continuous audio signal from the one or more quantized audio data in the original value.
