1. A method for restricting access to digital video content based on recognition of a TV station logo embedded within the video content that varies according to the video usage rights, the method comprising:
extracting the TV station logo from the video content by combining several frames of video content; identifying the TV station logo by comparing the TV station logo to known TV station logos that most closely matches said TV station logo extracted from the video content, where the known TV station logos are associated with user profiles of copyright rights holders, and wherein at least some of the known TV station logos are supplied by rights holders for content analysis to identify their owned content; estimating a first match probability of the likely copyright rights holder based on the identified TV station logo; identifying a second media object within at least one frame of the video content different from the TV station logo; extracting at least a second semantic property from the second specified media object within at least one frame of the video content; matching said at least second semantic property of the second specified media object against the known semantic properties of known media objects associated with user profiles of copyright rights holders; comparing matches between said at least second semantic property and the known semantic properties to a second threshold value; estimating a second match probability of the likely copyright rights holder based on the second compared matches; combining the first match probability and the second match probability into a combined match probability; identifying a copyright rights holder based on at least the combined match probability; retrieving rules governing distribution rights of the content based at least on identification of the copyright rights holder; and restricting access to the digital video content in accordance with the retrieved rules.
