Different versions of the media content are produced using the first data. Each of the different versions include one or more portions of the media content. The one or more portions are selected using the first data. Second data is associated with the different versions. The second data identifies respective protection attributes used to encrypt the different versions. The respective protection attributes correspond to respective keys that provide respective levels of access to the media content.
