Yes. Licenses to play digital media and PDF files
can specify start time, end time, license duration limits. If customers with an
expired license try to access a digital media file, they are directed back to
the DRM-X license acquisition page or your customize page to acquire license. In DRM-X, both start and expiration dates are supported, which creates great
flexibility. For example, a digital media or PDF file could be distributed with a
license that disables playback until the intended release date.
