YouTube’s Content ID system and approach to Fair Use (txt) 
YouTube describes its "mini takedown" process which allows rights holders to send a notice to an uploader to alert them that their video has been flagged by YouTube's content identification software (based on threshold parameters the owner inputs). This gives the opportunity for the user to informally raise a fair use defense, and helps rights owners to avoid "accidental" erroneous take downs. All this happens before the formal DMCA notice and takedown rigmarole which has problems because an automated ID system often leads to rights holders sending out too many take downs, which then cause all that content to be automatically taken down. This system lets the parties do a bit of pre-filtering before resorting to legal processes.
