Abstract
Various systems and methods for comparing media signals are disclosed. In some embodiments, media signals are compared by identifying characteristic features in the respective signals and then analyzing the characteristic features to determine if the signals contain corresponding content. In other embodiments, the characteristic features are analyzed to determine the extent to which the signals are synchronized in time.
