5. A method for restricting access to a media object based on automatic recognition of human recognizable semantic properties evident during playback of the media object, the method comprising: extracting at least one semantic property from a first specified media object within at least one frame of video content; matching said at least one semantic property of the first specified media object against known semantic properties of known media objects associated with user profiles of rights holders, wherein at least some of the known semantic properties are generated from material supplied by rights holders for content analysis to identify their owned content; comparing matches between said at least one semantic property and known semantic properties to a threshold value; estimating a first match probability of the likely copyright rights holder based on the compared matches; identifying a second media object within at least one frame of the video content different from the first media object; 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 video content based at least on identification of the copyright rights holder; and determining allowed actions that can be performed with respect to the media objects based upon the retrieved rules; restricting access to playback of video content containing the media objects in accordance with the allowed actions.

The method of claim 5 , further comprising: identifying a second media object within the video content different from the first media object; extracting at least a second semantic property from the second specified media object within 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; and identifying a copyright rights holder based on at least the combined match probability.
