Content information such as a movie, an audio file or a textual message is supplied to an end-user in a software object that has an encapsulated procedure for end-user access of the content information in a runtime environment. The object can specify time frame for and manner wherein the content information is to be accessed. Since the procedure is encapsulated in the object together with the content data, and since transport of the object over the Internet is done after serializing, an adequate degree of security is provided against unauthorized play-out or copying.
