Centralized content access management

1. A media content management server comprising:

a network interface;

control circuitry configured to:

receive, from a first remote server, first metadata associated with a first set of content items, the first metadata representing a first parameter for each of the first set of content items in a first data format;

receive, from a second remote server, second metadata associated with a second set of content items, the second metadata representing a second parameter for each of the second set of content items in a second data format different than the first data format; and

generate reformatted metadata at least in part by:

reformatting the first parameter of the first metadata from the first data format to a third data format using first adapter circuitry; and

reformatting the second parameter of the second metadata from the second data format to the third data format using second adapter circuitry; and

rules engine circuitry configured to generate a data transfer package for a vehicle at least in part by:

comparing the reformatted first parameter of the reformatted metadata to content access rule data to determine a subset of the first set of content items that is authorized for the vehicle;

comparing the reformatted second parameter of the reformatted metadata to the content access rule data to determine a subset of the second set of content items that is authorized for the vehicle; and

combining at least a portion of the subset of the first set of content items and at least a portion of the subset of the second set of content items to generate the data transfer package.

2. The server of claim 1 , wherein the control circuitry is further configured to transfer, using the network interface, the data transfer package to a remote server associated with the vehicle.

3. The server of claim 2 , wherein:

the control circuitry is further configured to receive, from the vehicle, an indication of a status change associated with the vehicle; and

said transferring the data transfer package is performed in response to the status change.

4. The server of claim 1 , wherein the data transfer package includes at least a portion of the content access rule data.

5. The server of claim 1 , wherein the first parameter and the second parameter are of a same type.

6. The server of claim 1 , wherein the control circuitry is further configured to receive, from a third remote server, at least a portion of the content access rule data.

7. The server of claim 1 , wherein the data transfer package is an update package.

8. The server of claim 1 , wherein the control circuitry is further configured to compare the subset of the first set of content items and the subset of the second set of content items with a list of content items already stored on the vehicle.

9. The server of claim 1 , further comprising:

non-volatile data storage media storing:

a media content library comprising the first and second sets of content items;

service offering content items; and

the content access rule data;

wherein the data transfer package includes at least some of the service offering content items.

10. The server of claim 1 , wherein the data transfer package includes content items for a plurality of different content types.

11. The server of claim 1 , wherein each of the first set of content items and the second set of content items comprises one or more of the following:

on-demand video content;

broadcast television content; and

advertisement content.

12. The server of claim 1 , wherein the control circuitry is further configured to:

receive, using the network interface, the first set of content items from the first remote server; and

receive, using the network interface, the second set of content items from the second remote server.

13. The server of claim 1 , wherein the content access rule data indicates a plurality of rules attributes associated with content access authorization, the plurality of rules attributes being associated with the first parameter and the second parameter.

14. The server of claim 13 , wherein the plurality of rules attributes indicate content access authorization based on two or more of:

a content item authorization start time;

a content item authorization end time;

a content item identifier;

a vehicle identifier;

a trip origin identifier;

a trip destination identifier;

a vehicle fleet identifier; and

a rule priority.

15. The server of claim 1 , wherein the first metadata comprises a set of key-value pairs associated with each of a plurality of the first set of content items.

16. The server of claim 1 , wherein:

the control circuitry is further configured to generate portal graphical interface data based on a vehicle identifier associated with the vehicle and the content access rule data; and

the data transfer package comprises the portal graphical interface data.

17. The server of claim 1 , wherein:

the first metadata includes first rule data related to the first set of content items;

the first rule data comprises one or more of authorization start time, authorization end time, and authorization geography data; and

the content access rule data includes the first rule data.
