1. A system, comprising:
- a fragment server configured to receive a request from a user to access a piece of media content at a first service level, the fragment server including a processor, the fragment server configured to fragment MPEG-4 files without out of band signaling, wherein a box structure is provided to include synchronization information and end of file information, wherein synchronization information is used to synchronize audio and video when playback entails starting in the middle of a stream and end of file information signals when the current program or file is over;
a storage device configured to maintain a service level authorized for the user;
wherein the fragment server is configured to access the storage device to determine whether the user is authorized to receive media content at a first service level at a first device and whether the user is authorized to receive media content at a second service level at a second device, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.

Abstract
Media rights are managed to include not just device authentication, but to include elements of user, device, and service authorization. A user can play media on a mobile device, continue playing the media on a desktop computer, and subsequently move to a large screen television and media rights are automatically identified to provide the most appropriate authorized content. This allows an authorized user to seamlessly access different forms of the same content on a variety of authenticated devices using the same digital rights management mechanisms.

11. A method, comprising:
-
identifying a user; authorizing the user to access a piece of media content at a particular service level by using a fragment server configured to fragment MPEG-4 files; receiving a first request from a first device to receive the media content, the request associated with a first service level, wherein the first request is received at the fragment server, the fragment server configured to fragment MPEG-4 files without out of band signaling, wherein a box structure is provided to include synchronization information and end of file information, wherein synchronization information is used to synchronize audio and video when playback entails starting in the middle of a stream and end of file information signals when the current program or file is over; determining that the user is authorized to receive the media content at the first service level by accessing stored service level authorized for the first device; transmitting the media content to the first device; receiving a second request from a second device to receive the media content, the request associated with a second service level; determining whether the user is authorized to receive the media content at the second service level by accessing stored service level authorized for the second device, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An apparatus, comprising:
-
means for identifying a user; means for authorizing the user to access a piece of media content at a particular service level; means for receiving a first request from a first device to receive the media content, the request associated with a first service level, wherein the first request is received at a fragment server, the fragment server configured to fragment MPEG-4 files without out of band signaling, wherein a box structure is provided to include synchronization information and end of file information, wherein synchronization information is used to synchronize audio and video when playback entails starting in the middle of a stream and end of file information signals when the current program or file is over; means for determining that the user is authorized to receive the media content at the first service level by accessing stored service level authorized for the first device; means for transmitting the media content to the first device; means for receiving a second request from a second device to receive the media content, the request associated with a second service level; means for determining whether the user is authorized to receive the media content at the second service level by accessing stored service level authorized for the second device, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.
