Abstract

An embodiment of a method includes receiving a subscription request specifying one or more destination sites to receive a video feed and respective times at which to deliver the video feed to each of the one or more destination sites over a terrestrial network, wherein respective delivery times are within a publication time range in which the video feed will be available, and configuring available resources to deliver the requested video feed to the one or more destination sites at the respective times.

First claim

What is claimed is:

1. A method of managing delivery of a video feed over a terrestrial network, the method comprising:
receiving, by at least one computing device, a publish request to make a video feed available within a publication time range;
receiving, by the at least one computing device, a subscription request specifying one or more destination sites to receive the video feed and respective times at which to deliver the video feed to each of the one or more destination sites;
determining that the respective delivery times are within the publication time range;
identifying, by the at least one computing device, one or more available network resources that are available at the respective delivery times, wherein the step of identifying comprises:
determining whether there is sufficient bandwidth on one or more ports of a video feed delivery device to deliver the requested video feed at each of the respective delivery times;

configuring the one or more available network resources to deliver the requested video feed to the one or more destination sites at the respective delivery times; and
de-allocating the available network resources after delivery of the requested video feed.

2. The method of claim 1 , wherein configuring available resources comprises reserving one or more ports of a replicator to deliver the requested video feed at the respective delivery times.

3. The method of claim 1 , further comprising sending a rejection message if there is insufficient bandwidth available to deliver the requested video feed at a requested delivery time.

4. The method of claim 1 , further comprising sending a reservation confirmation message confirming that resources are available to deliver the requested video feed if sufficient bandwidth is available.

5. The method of claim 1 , wherein configuring available resources comprises determining if resources are available to deliver the requested video feed at each of the one or more delivery times, and if resources are not available to deliver the requested video feed to one of the one or more destination sites, and resources are available to deliver the requested video feed to the other one or more destination sites, configuring only the available resources to deliver the video feed to the other destination sites at the respective delivery times.

6. A system for managing delivery of video feeds over a terrestrial network, the system comprising:
at least one processor;
memory, operatively connected to the at least one processor and containing instructions that, when executed by the at least one processor, cause the at least one processor to:
receive a publish request to make a video feed available within a publication time range;
receive a subscription request specifying a video feed and a plurality of requested delivery times and a respective plurality of destinations;
determine that the respective delivery times are within the publication time range;
determine a subset of the plurality of destinations to which the video feed can be delivered at one or more respective requested delivery times;
select a destination location from among the subset of destination locations to which the video feed can be delivered at the one or more respective requested delivery times;
reserve available network resources at the one or more respective requested delivery times for delivering a video feed to the selected destination location;
configure the available network resources for delivering the video feed to the selected destination location at the one or more respective requested delivery times; and
after the one or more requested delivery times have lapsed, mark the available network resources as no longer allocated to delivering the video feed.

7. The system of claim 6 , wherein the instructions further cause the at least one processor to determine whether sufficient network resources are available at an origination location and each of the plurality of destinations at the plurality of respective delivery times.

8. The system of claim 6 , wherein instructions further cause the at least one processor to select the destination location based on zones of locations.

9. The system of claim 6 , wherein instructions further cause the at least one processor to provide an online interface for subscribing to video feeds to be published.

10. The system of claim 9 , wherein the online interface presents video feeds that will be published and wherein the online interface receives subscriptions to one or more selected video feeds.
