Abstract
One aspect of the present invention is a method of playing multi-media content through a personal computer. The personal computer includes a processor and memory, with the memory having software instructions stored therein. The processor executes the instructions to carry-out the method. The method includes: receiving data representing multi-media content at the personal computer; receiving at the personal computer an initial set of data representing a base set of usage rights that is associated with the multi-media content, wherein the initial set of data defines a first set of rights that is permissible without upgrading or renewing the base set of usage rights; and upon receiving a request to perform an action involving the multi-media content, checking the initial set of data representing the base set of usage rights to determine whether the action is permissible, and providing an option to a user through the personal computer to contact a remote computer to negotiate for an upgraded set of usage rights. The transmission of the multi-media content is among those actions that are not permissible.
