Abstract
The invention discloses a method for controlling digital film play-count and a system thereof, wherein a play-count parameter is added into a KDM file where a key delivery message used for controlling film play is embedded, detecting the play-count parameter for a playing film, setting RSA key abstracts of an FDM packager of all authorized contracting film producers, safely importing the KDM and play-count into a security module, detecting the play-count parameter for a playing film. The film is not permitted to play unless existing play-count is less than the authorized play-count in the FDM. The invention fulfills the requirements and demands for controlling the distribution and playback of digital films in the second-tier market using technologies such as the authorized play-count and a method to charge on the basis of play-count.
