Abstract

Embodiments provide efficient delivery of multiple media channels to in-transport terminals, for example, to reduce channel zapping delay in a bandwidth efficient manner. For example, an in-transport media (ITM) server can distribute multiple channel offerings to ITM clients in a transport craft. Meanwhile, the ITM server can monitor which channel offerings are presently being consumed via the ITM clients, and can transmit feedback to a remote media server, accordingly. Based on the feedback, the ITM server can receive the channel offerings from the remote media server, in such a way that one or more of the channel offerings is received as a low-fidelity instance when not presently being consumed via any of the ITM clients, and one or more of the channel offerings is received as a high-fidelity instance when presently being consumed via at least one of the ITM clients.

Claims

1. An in-transport media (ITM) delivery system comprising:

an ITM distribution server disposed in a transport craft, the ITM distribution server comprising;

a channel distribution controller to distribute a plurality of media channel offerings to a plurality of ITM clients disposed in the transport craft;

a request controller to monitor the ITM clients to determine which of the channel offerings are presently being consumed via the ITM clients; and

a communications controller to communicate, to a remote media server via a communications network, feedback indicating which of the channel offerings are presently being consumed according to the monitoring,

wherein the channel distribution controller further operates to receive the channel offerings, from the remote media server via the communications network, such that one or more of the channel offerings is received as a low-fidelity instance when not presently being consumed via any of the ITM clients according to the feedback, and one or more of the channel offerings is received as a high-fidelity instance when presently being consumed via at least one of the ITM clients according to the feedback.

2. The ITM delivery system of claim 1, wherein the transport craft is an airplane.

3. The ITM delivery system of claim 1, wherein each low-fidelity instance is generated by capturing a sequence of snapshot images from linear programming associated with the respective channel offering.

4. The ITM delivery system of claim 1, wherein each low-fidelity instance is generated by applying a compression scheme to linear programming associated with the respective channel offering.

5. The ITM delivery system of claim 1, wherein the request controller determines that one of the channel offerings is presently being consumed via at least one of the ITM clients by detecting that at least one of the ITM clients has been tuned to the channel offering for at least a predetermined threshold dwell duration.

6. The ITM delivery system of claim 1, wherein the request controller determines that one the channel offerings is presently not being consumed via at least one of the ITM clients by detecting that none of the ITM clients has been tuned to the channel offering for at least a predetermined threshold release duration.

7. The ITM delivery system of claim 1, wherein the ITM distribution server further comprises local media storage, and a subset of the channel offerings is generated locally by the ITM distribution server to include content from the local media storage.

8. The ITM delivery system of claim 1, wherein each channel offering comprises linear programming.

9. The ITM delivery system of claim 1, wherein at least one of the plurality of ITM clients is a seatback entertainment system installed in the transport craft.

10. The ITM delivery system of claim 1, wherein at least one of the plurality of ITM clients is a personal electronic device of a passenger on the transport craft.

11. The ITM delivery system of claim 1, wherein the channel distribution controller further operates to receive the channel offerings, from the remote media server via the communications network, such that each of the channel offerings is received as both a low-fidelity instance and as a high-fidelity instance when presently being watched via at least one of the ITM clients according to the feedback.

12. The ITM delivery system of claim 1, wherein the communications network is a satellite communications network.

13. The ITM delivery system of claim 1, further comprising:

the plurality of ITM clients, each communicatively coupled with the ITM distribution server.

14. The ITM delivery system of claim 1, further comprising:

the remote media server communicatively coupled with the ITM distribution server via the communications network.

15. A method for distribution of media channel offerings in an in-transport communications system, the method comprising:

monitoring, by an in-transport media (ITM) server, while distributing a plurality of channel offerings to a plurality of ITM clients in the transport craft, which of the channel offerings are presently being consumed via the ITM clients;

transmitting, by the ITM server to a remote media server, feedback indicating which of the channel offerings are presently being consumed according to the monitoring;

receiving, by the ITM server from the remote media server, the channel offerings, such that one or more of the plurality of channel offerings is received as a low-fidelity instance when not presently being consumed via any of the ITM clients according to the feedback, and one or more of the plurality of channel offerings is received as a high-fidelity instance when presently being consumed via at least one of the ITM clients according to the feedback.

16. The method of claim 15, further comprising:

generating at least one of the low-fidelity instances by capturing a sequence of snapshot images from linear programming associated with its respective channel offering.

17. The method of claim 15, further comprising:

generating at least one of the low-fidelity instances by applying compression to linear programming associated with its respective channel offering.

18. The method of claim 15, wherein the monitoring comprises detecting, for each of the channel offerings, whether at least one of the ITM clients has been tuned to the channel offering for at least a predetermined threshold dwell duration.

19. The method of claim 15, wherein the monitoring comprises detecting, for each of the channel offerings, whether none of the ITM clients has been tuned to the channel offering for at least a predetermined threshold release duration.

20. The method of claim 15, wherein each of the channel offerings is received as both a low-fidelity instance and as a high-fidelity instance when presently being watched via at least one of the ITM clients according to the feedback.
