Abstract

Claims (13)

1. A system for synchronizing enhanced content with a broadcast signal provided from a broadcast system that has the ability to insert content or triggers into the broadcast signal, and has a playlist with broadcast event and timing information, the system comprising:

a synchronization application receiving timing information from the playlist and using that timing information to generate synchronization triggers, the synchronization application residing in a device other than a first end user device;

a content server configured to receive the synchronization trigger from the synchronization application and push content to the first end user device over a channel separate from the broadcast signal; and

a trigger insertion application configured to receive the synchronization trigger from the synchronization application for causing the broadcast system to insert a content trigger that allows a second end user device to pull the enhanced content from the server using the content trigger.

2. The system of claim 1 , wherein the broadcast system includes a character generator, the content server creating content and providing the content to the character generator in an automated manner for insertion into the broadcast signal.

3. The system of claim 1 , wherein the broadcast system includes an encoder, wherein the trigger insertion application provides the content trigger to the encoder for insertion.

4. The system of claim 1 , further comprising a remote content authority for creating content, the content authority receiving trigger information from the synchronization application and providing trigger information to the trigger insertion application.

5. The system of claim 1 , wherein the synchronization application provides trigger information directly to the trigger insertion application.

6. The system of claim 1 , wherein the device hosting the synchronization application is a coordination system coupled to the content server for coordinating delivery of the enhanced content.

7. A method for synchronizing enhanced content with a broadcast signal provided from a broadcast system, the method comprising:

receiving timing information from a playlist and using the timing information to generate an ITV content trigger;

providing the ITV content trigger to a content server by a device other than a first or second type of end user device; and

using the ITV content trigger to concurrently push and pull enhanced content corresponding to the ITV content trigger, wherein the pushing is conducted by a content server for pushing the enhanced content to the first type of end user device, and the pulling is conducted by the second type of end user device for pulling the enhanced content from the content server.
