  • Method and system for generating an audio metadata quality score
    Patent number: 9373334
    Abstract: A method including the steps of assessing at least two metadata parameters associated with an audio bitstream (e.g., an encoded Dolby Digital (AC-3), Dolby Digital Plus, or Dolby E bitstream), determining individual metadata parameter quality values, each of the individual metadata parameter quality values indicative of quality (e.g., correctness) of a different one of the at least two metadata parameters, and generating data indicative of a metadata score, where the metadata score is a value determined by a combination (e.g., a linear combination or other weighted combination) of the individual metadata parameter quality values. The metadata score is indicative of overall quality (e.g., correctness) of the at least two metadata parameters. Another aspect is a system (e.g., a test device or measurement device, or another test or measurement product, or a processor) configured (e.g., programmed) to perform any embodiment of the method.
