Question:

What about at the DRM content where the license had been lost?

Answer:

There is not problem if the license is lost for a content in the AXMEDIS based DRM. The license is in the hands/device of the final user if the license is stored into the local secure cache to allow using the content without an on-line connection. If the license stored locally is lost a new instance of the same license is obtained at the next connection. In fact, the DRM license is hosted in the AXMEDIS PMS (a licensing server). The licensing servers can be connected each other to create fault tolerant, high performance servers. In any case the license can be reissued identically to the initial license from the distributor according to its data.
