A method, system, mobile device, apparatus and computer program product are provided for accurately determining whether one or more rights objects associated with a mobile device are valid. In particular, a secure time source (e.g., DRM clock or time) may be maintained by the mobile device and used to check the validity of the one or more rights objects. In order to ensure that the secure time source or clock remains accurate, the mobile device may update the secure time source by regularly requesting and receiving the DVB-H network time from a DVB-H network entity. Because the DVB-H network time is secure, accurate and readily accessible, it provides an ideal tool for correcting possible drift in the mobile device's secure time source.
A method of determining whether one or more rights objects associated with a mobile device are valid, said method comprising:
A system for determining whether one or more rights objects associated with a mobile device are valid, said system comprising:
A mobile device configured to determine whether one or more rights objects associated with the mobile device are valid, said mobile device comprising:
An apparatus capable of determining whether one or more rights objects associated with a mobile device are valid, said mobile device comprising:
A computer program product for determining whether one or more rights objects associated with a mobile device are valid, wherein the computer program product comprises at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
