Communicating media content from a DVR to a portable device |
摘要 |
In a method for communicating media content stored on a digital video recorder (DVR) protected by a first DRM system to a portable multimedia device (PMD) using a second DRM system, in which the first DRM system differs from the second DRM system, a request for communication of a media content item stored on the DVR to the PMD is received. In addition, a portable content key is employed to encrypt the media content item to a PMD format suitable content version and the encrypted PMD format suitable content version is communicated to the PMD along with a portable content identifier (ID).
