An MPEG-21 based framework for delivery of protected content

This is an end-to-end framework for search a delivery of protected media content, based on the MPEG-21 concept of "digital item". The digital item concept enables unified machine-readable description of media content - including its structure, location, format, characteristics, usage instructions and licensing terms. In other words, it’s an abstraction of the physical media piece including its "box", plus all the information that is found inside the box.

The other main feature of the framework is its ability to handle end-to-end protection. End to end protection is that situation when a media item is created, and protection measures, such as encryption, are applied to the media at creation time. Once it is created the item can be carried by various means, including physical media and various kinds of network, without exposing its valuable content to non-licensed access. The media is accessible when arriving to its final destination - an authenticated user who has acquired the license to access the media and been given the tools to do so.

The use potential of this framework is enormous. The approach has the potential of moving the entire media market to online distribution channels, while solving two of the main hurdles that are currently impeding this trend: the difficulty to find content that is guaranteed to play on one’s device, and the enforcing of property rights.

The result is innovative in few aspects. One is the success to compile the theoretical MPEG-21 DI specifications into a working framework where items from different vendors and of different characteristics are seamlessly integrated. Most notable is the accomplishment the present to and end user local, remote and broadcast media items in a unified way that lets the user access the item transparently without being aware of its format or location.

The other innovative aspect of this result is the pioneering of the end-to-end protection technology. Currently protection measures exist in platform such as paid channels in digital TV, but in call current cases the protection is done on the delivery channel. It is not possible to record a media item or view it outside its designated receiving channel. If somehow the system is tampered and the received items are recorded, they are consequently available in clear text and the licensing rules are violated. With this result of the project we can protect the content until it arrives to a licensed client more efficiently, while still allow unlicensed clients to distribute the item by any appropriate means.

This result of the project is not exploitable as a stand-alone product but rather enables a wide range of products and services. Optibase intends to enrich its products and develop new ones based on market acceptance of the approach pioneered by this result.
