Abstract

Entertainment systems for aircraft and other vehicles are described having a plurality of media players. The media players collectively store a full content set, with each media player storing only a fraction of the full content set. Each of the media players can be configured to index the full content set, such that media players can obtain missing content from other media players.

Claims

1. A vehicular entertainment system, comprising:

a first plurality of media players disposed within a vehicle that collectively store multiple copies of a first full content set spread across the first plurality of media players, each of the media players storing only a fraction of the first full content set;

and a second plurality of media players disposed within the vehicle that collectively store multiple copies of a second full content set spread across the plurality of second media players, each of the second media players storing only a fraction of the second full content set;

and wherein each of the media players in the first plurality of media players and the second plurality of media players is configured to;

index the first full content set collectively stored by the first plurality of media players according to a first scheduled period, to allow each of the media players to obtain content from the first full content set during the first scheduled period;

and index the second full content set collectively stored by the second plurality of media players according to a second scheduled period, to allow each of the media players to obtain content from the second full content set during the second scheduled period, wherein the first scheduled period comprises a first month long period and the second scheduled period comprises a second month-long period and wherein the first scheduled period and the second scheduled period are mutually exclusive.

2. The system of claim 1, wherein the first plurality of media players are disposed within at least one of seatbacks, seat arms, and bulkheads of the vehicle.

3. The system of claim 2, wherein the first full content set is striped across media players in a seat group.

4. The system of claim 3, wherein the seat group comprises a set of media players in a seat row.

5. The system of claim 2, wherein the first plurality of media players are each configured to provide their fraction of the first full content set to other media players lacking the content based on seat-row addressing.

6. The system of claim 2, wherein the first plurality of media players are each configured to provide their fraction of the first full content set to other media players lacking the content based on seat-column addressing.

7. The system of claim 6, wherein fractions of the first full content set are mirrored across media players in seat columns.

8. The system of claim 6, wherein the media players of a seat column are coupled via a wireless connection.

9. The system of claim 1, wherein at least two of the media players collectively comprise the first full content set.

10. The system of claim 1, wherein the first full content set is collectively stored across X media players in a RAID array, where X is at least three.

11. The system of claim 10, wherein the first full content set comprises first and second subsets, and wherein Y media players are required to form the first subset and Z media players are required to form the second subset, and wherein Y is less than Z, which is less than X.

12. The system of claim 10, wherein the X media players each comprise overlapping fractions of the first full content set.

13. The system of claim 10, wherein Y media players are required to form the first full content set, and wherein Y is less than X.

14. The system of claim 13, wherein the ratio of Y/X is no greater than ⅓

.

15. The system of claim 13, further comprising:

a second plurality of media players disposed within a second plurality of seatbacks of the vehicle that collectively store a second full content set, each of the second plurality of media players storing only a fraction of the second full content set, and wherein each of the second plurality of media players is configured to index the full content set;

wherein the X media players are disposed in a first set of seatbacks of the vehicle having a different size and dimension than the second set of seatbacks; and

wherein the second full content set is collectively stored in a RAID array across W media players of the second plurality of media players, where W is at least three, and wherein Z media players are required to form the second full content set, where Z is less than Y.

16. The system of claim 1, further comprising an in-vehicular wireless network communicatively coupling the first plurality of the media players to each other.

17. The system of claim 1, wherein the storage device of each player is field replaceable.

18. A vehicular entertainment system, comprising:

a plurality of media players disposed within a vehicle that collectively store multiple copies of a full content set spread across the plurality of media players, wherein the plurality of media players comprises first and second subsets of media players;

wherein the first subset of media players collectively stores a first copy of the full content set with each media player of the first subset stores only a fraction of the first copy of the full content set;

wherein the second subset of media players collectively stores a second copy of the full content set with each media player of the second subset stores only a fraction of the second copy of the full content set;

and wherein each of the media players of the first and second subsets is configured to index the first and second copies of the full content set collectively stored by the media players of the first and second subsets according to a first scheduled period and a second scheduled period, respectively, wherein the first scheduled period comprises a first month-long period and the second scheduled period comprises a second month-long period and wherein the first scheduled period and the second scheduled period are mutually exclusive.
