1. A system comprising:
- a server capable of providing a first digital content unit, C.a(x), wherein content, C, is coded with a first digital format, .a, and use-right protected by a first digital rights management (DRM), x, wherein the first DRM includes usage parameters;
a translator capable of converting the first digital content unit into a second digital content unit, C.b(y), wherein the content is coded with a second digital format, .b, and use-right protected by a second DRM, y;
wherein, in operation, the server provides the first digital content unit, the translator converts the first digital content unit to a second digital content unit, and the content is executed on a player that is compatible with the second digital content unit.
