Abstract:
A media storage device includes a media security controller circuit and a memory to store data that relates to a media item to be rendered by a rendering device. The media security controller circuit sends a message to the rendering device that causes the rendering device to obtain a portion of data from memory of the media storage device and provide it to the media security controller circuit. The portion is received and transformed by the media security controller circuit. The media security controller circuit sends the transformed portion to the rendering device.
