Abstract

According to some embodiments, methods, systems, apparatus, means and computer program products are provided which allow the remote production of live events by capturing, at a remote event site, event video data in a first time horizon. The event video data is compressed to a proxy of the event video data, and the proxy event video data is transmitted to a remote production facility. A switcher at the production facility is operated to generate commands to produce a proxy program using the proxy event video data. The commands are associated with a second time horizon delayed from the first time horizon. The commands are then transmitted to the remote event site to cause a shadow switcher to produce a cut program in third time horizon delayed from the second time horizon, where the cut program is produced using the event video data. The cut program is transmitted to the production facility, where additional data may be keyed into the cut program in a fourth time horizon, where the fourth time horizon delayed from the first, second and third time horizons. The resulting program is the broadcast program that can be broadcast and distributed.

Claims

1. A method comprising:

capturing, at a remote event site, event video data in a first time horizon;

compressing the event video data to create proxy event video data, and transmitting the proxy event video data to a production facility;

generating, at a switcher at the production facility, commands to produce a proxy program using the proxy event video data, the commands associated with a second time horizon delayed from the first time horizon;

transmitting the commands to the remote event site to cause a shadow switcher to produce a cut program in a third time horizon delayed from the second time horizon, the cut program produced using the event video data; and

transmitting the cut program to the production facility.

2. The method of claim 1, further comprising:

keying additional data into the cut program in a fourth time horizon, the fourth time horizon delayed from the first, second and third time horizons, to generate a broadcast program.

3. The method of claim 2, wherein capturing further includes capturing event audio data and the broadcast program is further generated using the event audio data.

4. The method of claim 2, wherein compressing the event video data to create proxy event video data comprises down-converting the event video data.

5. The method of claim 2, wherein at least one of the first time horizon, the second time horizon, the third time horizon, and the fourth time horizon are associated with one or more monotonic identifiers.

6. The method of claim 4, wherein down-converting the event video data comprises down converting high definition (“

HD”

) event video data to standard definition (“

SD”

) event video data.

7. The method of claim 1, wherein transmitting the proxy event video data to a production facility is performed over a backhaul network comprising at least one of (i) a fiber cable and a (ii) a satellite transmission network.

8. The method of claim 6, wherein the second time horizon is based on a latency associated with the backhaul network.

9. The method of claim 6, further comprising transmitting event audio data to the production facility over the backhaul network.

10. The method of claim 6, wherein the transmitting the cut program to the production facility includes transmitting the cut program over the backhaul network, and where the fourth time horizon further is based on a latency of the backhaul network.

11. The method of claim 1, wherein the transmitting the commands to the remote event site includes transmitting the commands over a fronthaul channel, and the third time horizon further is based on a latency associated with the fronthaul channel.

12. The method of claim 1, wherein the broadcast program is an HD program.

13. A mobile production vehicle system for interacting with a production facility to remotely produce a broadcast event, comprising:

a first subsystem for capturing, at a remote event site associated with the mobile production vehicle, event video data in a first time horizon;

a second subsystem for compressing the event video data into proxy event video data, and transmitting the proxy event video data to the production facility over a backhaul network, the production facility using the proxy event video data to produce a proxy program associated with a second time horizon delayed from the first time horizon;

14. The system of claim 13, wherein the event video data are captured by a plurality of cameras arranged to capture images at the live event.

15. The system of claim 13, wherein compressing the event video data to a proxy of the event video data comprises down-converting the event video data to standard definition (“

SD”

) event video data.

16. The system of claim 13, wherein the backhaul network is at least one of (i) a fiber cable and a (ii) a satellite transmission network.
