摘要：Media and entertainment content is increasingly used on mobile devices. While consumers
want interoperable services that are easy to use and can be shared with others, content
providers and mobile operators are looking to protect their investment in high value content.

content. Within only 18 months, OMA DRM has become the most widely available mobile DRM
standard implemented on currently over 80 handsets from all major phone manufacturers.
