Abstract

Claims (58)

1. A system for network transmission of media files, the system comprising:

a plurality of media delivery subsystems coupled to a media distribution device via a communications network, the plurality of media delivery subsystems configured to deliver a plurality of media files to end users;

a media distribution device configured to:

determine a current order of distribution, wherein the current order of distribution specifies an order in which the media distribution device currently intends to transmit the plurality of media files to the plurality of media delivery sub systems;

transmit to the plurality of media delivery subsystems a preview message indicating the current order of distribution;

the plurality of media delivery subsystems configured to transmit temporal priority feedback messages to the media distribution device based, at least in part, on the preview message, the temporal priority feedback messages for individual media delivery subsystems indicating a temporal priority of the plurality of media files from a perspective of the individual media delivery subsystems;

the media distribution device further configured to:

determine that the current order of distribution is to be re-evaluated;

determine a revised order of distribution based, at least in part, on the temporal priority feedback messages; and

transmit the plurality of media files to the plurality of media delivery subsystems in the revised order of distribution.

2. The system of claim 1 , wherein the media distribution device is further configured to:

determine that the current order of distribution is to be re-evaluated based on expiration of a fixed time interval.

3. The system of claim 1 , wherein the media distribution device is further configured to:

determine that the current order of distribution is to be re-evaluated based on a variable time interval.

4. The system of claim 3 , wherein the media distribution device is further configured to:

adjust the variable time interval based, at least in part, on the temporal priority feedback messages.

5. The system of claim 4 , wherein the media distribution device is further configured to:

increase the variable time interval in response to determining that the temporal priority feedback messages require fewer than a threshold number of changes to the current order of distribution.

6. The system of claim 5 , wherein changes to the current order of distribution include one or more of removing, adding, or substituting media items indicated by the preview message.

7. The system of claim 4 , wherein the media distribution device is further configured to:

decrease the variable time interval in response to determining that a plurality of temporal priority feedback messages require changes to the current order of distribution.

8. A method for use in network transmission of media files, the method comprising:

determining, at a media distribution device, a current order of distribution for a plurality of media files, wherein the current order of distribution specifies an order in which the media distribution device currently intends to transmit the plurality of media files to a plurality of media delivery subsystems via a communications network;

transmitting, from the media distribution device to the plurality of media delivery subsystems, a preview message indicating the current order of distribution;

receiving, from the plurality of media delivery subsystems, temporal priority feedback messages, each temporal priority feedback message indicating a temporal priority of the plurality of media files from a perspective of an individual media delivery sub systems;

determining, at the media distribution device, that the current order of distribution is to be re-evaluated;

determining, at the media distribution device, a revised order of distribution based, at least in part, on the temporal priority feedback messages; and

transmitting the plurality of media files from the media distribution device to the plurality of media delivery subsystems in the revised order of distribution.

9. The method of claim 8 , further comprising:

determining, at the media distribution device, that the current order of distribution is to be re-evaluated based on expiration of a fixed time interval.

10. The method of claim 8 , further comprising:

determining, at the media distribution device, that the current order of distribution is to be re-evaluated based on a variable time interval.

11. The method of claim 10 , further comprising:

adjusting the variable time interval based, at least in part, on the temporal priority feedback messages.

12. The method of claim 11 , further comprising:

increasing the variable time interval in response to determining that the temporal priority feedback messages require fewer than a threshold number of changes to the current order of distribution.

13. The method of claim 12 , wherein changes to the current order of distribution include one or more of removing, adding, or substituting media items indicated by the preview message.

14. The method of claim 11 , further comprising:

decreasing the variable time interval in response to determining that a plurality of temporal priority feedback messages require changes to the current order of distribution.

15. A media distribution device comprising:

a processor;

memory associated with the processor;

a program of instructions to be stored in the memory and executed by the processor, the program of instructions including:

at least one instruction to determine a current order of distribution for a plurality of media files, wherein the current order of distribution specifies an order in which the media distribution device currently intends to transmit the plurality of media files to a plurality of media delivery subsystems via a communications network;

at least one instruction to transmit, from the media distribution device to the plurality of media delivery subsystems, a preview message indicating the current order of distribution;

at least one instruction to receive, from the plurality of media delivery subsystems, temporal priority feedback messages, each temporal priority feedback message indicating a temporal priority of the plurality of media files from a perspective of an individual media delivery subsystem;

at least one instruction to determine that the current order of distribution is to be re-evaluated;

at least one instruction to determine a revised order of distribution based, at least in part, on the temporal priority feedback messages; and

at least one instruction to transmit the plurality of media files from the media distribution device to the plurality of media delivery subsystems in the revised order of distribution.

16. The media distribution device of claim 15 , further comprising:

at least one instruction to determine that the current order of distribution is to be re-evaluated based on a variable time interval.

17. The media distribution device of claim 16 , further comprising:

at least one instruction to adjust the variable time interval based, at least in part, on the temporal priority feedback messages.

18. The media distribution device of claim 17 , further comprising:

at least one instruction to increase the variable time interval in response to determining that the temporal priority feedback messages require fewer than a threshold number of changes to the current order of distribution.

19. The media distribution device of claim 18 , wherein changes to the current order of distribution include one or more of removing, adding, or substituting media items indicated by the preview message.

20. The media distribution device of claim 17 , further comprising:

at least one instruction to decrease the variable time interval in response to determining that a plurality of temporal priority feedback messages require changes to the current order of distribution.
