Methods and apparatus to perform media device asset qualification
Methods, apparatus, systems and articles of manufacture to perform media device asset qualification are disclosed. An example apparatus includes an asset quality evaluator to identify candidate media device assets obtained from a media device that identify media. The example apparatus further includes an asset grader to grade the candidate media device assets based on calculating a valid hash count corresponding to a number of matches between a first one of the candidate media device assets compared to a second one of the candidate media device assets using a hash table, and identify the first one of the candidate media device assets as a reference media device asset, the first one having a higher grade compared to grades of other candidate media device assets. The example apparatus further includes an asset loader to generate a validation report including the identification of the reference media device asset.
