Abstract

The copy may be rendered non-permanent by streaming it, by encrypting it, and by appending a first instruction to automatically delete it after playing. The first MSmay be given an option of delivery pathways, such as cellular, WLAN, or DVB-H. After playing, an offer is made to the second MSto purchase a permanent copy of the media file.
