Network attached DVR storage

摘要

A host device, which may include a DVR, selects to record content on the host device DVR or in a network attached storage (NAS) unit. The recorded content remains bound to the host device from a DRM perspective when it is recorded on the host DVR and on the remotely located NAS. A client device can obtain access to content recorded on the NAS by negotiating DRM rights with the host device instead of the NAS. When access rights are approved, the host device provides access information to the client device so that the content is streamed directly to the client device from the NAS.
