(57) ABSTRACT
Enforcing rendering advertisements and other predetermined media content in connection with playback of downloaded selected media content. Playback of selected media content is made conditional on acquisition of a playback token that is generated in response to playback of the predetermined content. The playback token may be implemented as a digital rights management (DRM) license acquired in response to playback of the predetermined content. Another aspect involves a content insertion engine for inserting ads or other predetermined content into the playback of downloaded content.
