Abstract
A method for implementing multiple clock interfaces in a single media player. The method and accompanying device are configured to utilize the preferred secure clock. If the remote host cannot support a secure clock, the method can alternately implement an anti-rollback clock interface. For each download session the clock data is separately maintained for subsequent access during playback of the corresponding content. The method supports secure digital rights management content downloads.
