Technical Examples
  1. A method and an apparatus for providing digital quality transmission of audio and non-audio information using low cost components and arrangement. The present invention provides for the transmission of the audio and non-audio transmission by first converting the data to conform to the CD standard format and conditioning the converted signal to thereby generate a conditioned EFM signal. The conditioned EFM signal is used to frequency modulate a carrier. By converting the audio and non-audio information to conform to the CD standard format, the present method provides a low cost means of transmitting the data with error detection and correction. Another aspect of the present invention relates to embedding the non-audio information in the SUBCODE block of the data frame according to the CD standard. The non-audio information may be unrelated to the audio information, and the audio and non-audio information may be transmitted to separate devices. Another aspect of the present invention relates to controlling a voltage controlled oscillator in response to the fill level of a file buffer in the decoder.
