1. Scope (Informative)
The scope of OMA Download is procedures for making the downloading of media objects from the Web easy and reliable,
and possible to charge for. Also in the scope of OMA Download is the ability to preview media objects and to prevent
downloaded content from being forwarded (copied) to other users. Preview and copy protection are part of Digital Rights
Management (DRM). A complete DRM technology is, however, not in scope of OMA Download. These basic DRM features
- preview and copy protection - are included because of the urgency to deploy a standardised solution.
