Abstract
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.
Claims15
An apparatus for recording user selected content comprising:
- a receiver which receives content from a network;
- a processing unit which identifies content to be recorded based on instructions from a user, determines digital rights management (DRM) rights to record content and access recorded content, and selects a recording location for recording the content,
- wherein the processing unit selects to record the content on a local digital video recorder (DVR) or a remotely located network attached server (NAS), and
- wherein the processing unit provides DRM negotiation for accessing content recorded on both the local DRV and the NAS.
A method of playing back recorded content comprising the steps of:
- receiving a request at a DVR capable host device from a client device to access recorded content, the host device and the client device being contained in a local area network (LAN);
- determining a recording location of the recorded content to be at a network attached storage unit (NAS) within the LAN;
- performing a DRM dialog between the client device and the host device to obtain access to the recorded content;
- and
- providing instructions to the client device to enable the content to be provided to the client device from the NAS without performing a DRM dialog between the client device and the NAS.
A non-transitory computer readable medium carrying instructions for a processor to perform a method of playing back recorded content comprising the steps of:
- receiving a request at a DVR capable host device from a client device to access recorded content, the host device and the client device being contained in a local area network (LAN);
- determining a recording location of the recorded content to be at a network attached storage unit (NAS) within the LAN;
- performing a DRM dialog between the client device and the host device to obtain access to the recorded content;
- and
- providing instructions to the client device to enable the content to be provided to the client device from the NAS without performing a DRM dialog between the client device and the NAS.
