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 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, wherein the respective delivery times are within a publication time range in which the video feed will be available; identifying 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 , further comprising receiving a publication request specifying the publication time range.

3 . 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.

4 . 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.

5 . 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.

6 . 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.

7 . A system for managing delivery of video feeds over a terrestrial network, the system comprising:
a resource scheduler operable to:
receive a subscription request specifying one or more requested delivery times and respective one or more destinations;
select a destination location from among the one or more destination locations to which the video feed can be delivered;
reserve available network resources at the one or more requested times for delivering a video feed to the selected destination location;
release the available network resources after the one or more requested delivery times have lapsed; and
a configuration module operable to configure the available network resources for delivering the video feed to the selected destination location at the respective times at which resources are available.

8 . The system of claim 7 , wherein the resource scheduler is further operable to receive a publication request specifying a publication time window in which the video feed will be available for delivery.

9 . The system of claim 8 , wherein the resource scheduler is further operable to determine whether each of the one or more requested delivery times are within the publication time window.

10 . The system of claim 7 , wherein the resource scheduler is operable to determine whether sufficient network resources are available at an origination location and each of the one or more destinations at the respective delivery times.

11 . The system of claim 7 , wherein the resource scheduler selects the destination location based on zones of locations.

12 . The system of claim 7 , wherein the resource scheduler provides an online interface for subscribing to video feeds to be published.

13 . The system of claim 12 , 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.
