Abstract

An intelligent asset management system is disclosed which includes a schedule manager for evaluation of predetermined events particular to each asset and predetermined requirements for distribution, updating, and deletion of the asset in view of real time current conditions and constraints; a resource manager for optimizing the utilization of hard disk storage devices on the system as well as optimizing the use of other types of storage devices available; a configuration manager that tracks and provided updated asset Metadata, application information, storage disk topology, bandwidth topology, weighting factors, and timing information for each asset; and a reporting and polling manager which tracks actual activity on the system such as user input and demands, and provides periodic reporting capabilities for the operators of the system.

Claims

1. A media asset management system for scheduling utilization, distribution and storage of a media asset being provided to viewers over a media asset distribution network comprising:

a resource means for managing media asset traffic in the distribution network by managing the storage of a media asset, said media asset including metadata, and generating registry information for the media asset, said registry information indicating actual usage of the media asset;

schedule means responsive to said resource means for copying or deleting a media asset and the registry information associated with the media asset;

a usage means responsive to the registry information for generating asset availability information for a media asset based on said media asset metadata, a number of copies of the media asset, and actual usage of the media asset;

said resource means querying said usage means for asset availability information of a media asset and generating a copy instruction or a delete instruction for a media asset depending on the asset availability information;

said schedule means responsive to the copy instruction for copying the media asset and registry information associated with that media asset; and

said schedule means responsive to the delete instruction for deleting a copy of the media asset and registry information associated with that copy of the media asset.

2. The system in accordance with claim 1 wherein a plurality of registers store the registry information indicating bandwidth topology, weighting factors and timing information for network components and media assets.

3. The system according to claim 2 wherein said resource means further comprises:

a bandwidth means for monitoring bandwidth topology and determining available unused bandwidth for transmission of an asset over the distribution network to a viewer.

4. The system according to claim 2 wherein said resource means further comprises:

weighting means for prioritizing media assets for copying and deleting in accordance with weighting factors in the registry information for the media assets.

5. The system according to claim 2 wherein said resource means further comprises:

timing means responsive to the timing information for prioritizing assets for copying and deleting in accordance with timing information from said registers.

6. In a media asset distribution system, a method for managing storage of a media asset at an operation center and distribution of the media asset over a distribution network from the operation center to end users, said media asset including asset specific metadata, said method comprising the steps of:

storing a copy of a media asset and said asset specific metadata, and generating registry information for each stored copy of the media asset, said registry information including actual usage of the media asset;

determining excess copies or not enough copies of a media asset based on a number of stored copies of the media asset, said asset specific metadata, and actual usage of the media asset;

in response to not enough copies of a media asset, determining from said asset specific metadata whether an additional copy of said media asset may be made and, if so, making and storing an additional copy of the media asset and the registry information for the additional copy of the media asset; and

in response to excess copies of a media asset, deleting a copy of the media asset and registry information associated with that copy of the media asset.

7. The method of claim 6 wherein the registry information further comprises bandwidth topology, and said method further comprises the steps of:

comparing bandwidth topology choices for distribution of the media asset to end users;

computing net available bandwidth for distribution of the media asset to the end users; and

said determining step responsive to said net available bandwidth in determining excess copies and not enough copies.

8. The method of claim 7 wherein the registry information further comprises asset type and timing information, and said method further comprises the step of:

prioritizing the copy order and deletion order of media assets in accordance with the timing information and the asset type.

9. The method of claim 8 wherein the registry information further comprises asset type and weighting factors for each asset type, and said method further comprises the step of:

prioritizing the copy order or deletion order of media assets based on the asset type of the media asset and the weighting factor for each asset type.

10. The method of claim 6 wherein the registry information further comprises asset type and timing information, and said method further comprises the step of:

prioritizing the copy order and deletion order of media assets in accordance with the timing information and the asset type.

11. The method of claim 6 wherein the registry information further comprises asset type and weighting factors for each asset type, and said method further comprises the step of:

prioritizing the copy order or deletion order of media assets based on the asset type of the media asset and the weighting factor for each asset type.

12. A media asset management system for scheduling utilization, distribution and storage of a media asset being provided to viewers over a media asset distribution network comprising:

a resource means for managing media asset traffic in the distribution network by managing the storage of a media asset, said media asset including metadata providing at least a permissible number of copies available on predetermined dates, and generating registry information for the media asset, said registry information indicating actual usage of the media asset;

schedule means responsive to said resource means for copying or deleting a media asset and the registry information associated with the media asset according to said predetermined dates;

a usage means responsive to the registry information for generating asset availability information for a media asset based on said media asset metadata, a number of copies of the media asset, and usage of the media asset;

said resource means querying said usage means for asset availability information of a media asset and generating an add copy instruction or delete copy instruction for a media asset depending on the asset availability information;

said schedule means responsive to the add copy instruction for copying the media asset and registry information associated with that copy of the media asset; and

said schedule means responsive to the delete copy instruction for deleting a copy of the media asset and registry information associated with that copy of the media asset.

13. In a media asset distribution system, a method for managing storage of a media asset at an operation center and distribution of the media asset over a distribution network from the operation center to end users, said method comprising the steps of:

storing a copy of a media asset including asset specific metadata providing number of permissible copy information, and generating registry information for each stored copy of the media asset, wherein said registry information includes actual usage of the media asset;

determining excess copies or not enough copies of a media asset based on a number of stored copies of the media asset, said asset specific metadata, and actual usage of the media asset on said network;

determining from said asset specific metadata, in response to not enough copies of a media asset, whether an additional copy of said media asset may be made and, if so, making and storing an additional copy of the media asset and the registry information for the additional copy of the media asset; and

in response to excess copies of a media asset, deleting a copy of the media asset and updating the registry information associated with that copy of the media asset.
