As digital broadcasting has become widespread and the available bandwidth for Internet access has become wider, more high-quality digital content has been distributed to users, making illegal copying a critical issue in the content business. New technology for identifying illegally distributed content is necessary to deter it. We developed two methods for identifying video content: the extraction of characteristic information from video and the use of phase-only correlation. A system was developed to apply these methods to digital TV programs. Experiments on four weeks of broadcast content gave good results, which suggests that a combination of the two methods would enable us to identify video content distributed illegally over the Internet precisely and quickly.
