摘要:
Systems and methods for securely executing digital rights management software comprising content code are described. One method comprises receiving encrypted multimedia content and content code from a storage medium by a host processor, wherein the content code provides restricted content distribution by examining an environment in which a player application resides. Based on functions defined within the content code, the host processor partitions the content code into portions. Based on whether the functions corresponding to the portions are related to computations involving confidential data, commands and parameters related to the portions of the content code are generated and forwarded to a secure processor for decrypting the encrypted multimedia content.

The present invention disclosed a multiple display method. A media data is received and a first program corresponding to the media data is displayed on a first frame of a display device. The media data is analyzed to generate a second program according to a predetermined event. The second program is displayed on a second frame of the display device while displaying the first program on the first frame on a real time basis.

A method for activating video-audio data in an optical disc includes determining whether a first activation signal is received or not, a program in the optical disc allowing access to partially-featured contents of the video-audio data when the first activation signal is not received, and the program in the optical disc allowing access to fully-featured contents of the video-audio data when the first activation signal is received.
