Remote Live TV Production via Proxy Signal Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote production of live broadcast events is costly and impractical due to the need for extensive equipment and personnel at the event site, and network bandwidth limitations often prevent the transmission of high-definition video signals, making it difficult to broadcast events remotely.
Innovation Solution
The system captures event video and audio data, converts it into a lower bandwidth proxy signal, and transmits this to a production control facility where it is uncompressed and used to generate a proxy program. Commands are then sent back to the event site to produce a cut program, which is transmitted back to the control facility for finalization and distribution, allowing for remote production using existing network infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high definition video signals are transmitted from remote event site to production control facility, then video quality is improved, but network bandwidth requirements become prohibitively high
Solution Approach 1:
The video signal transmission is segmented into two separate paths: uncompressed high-definition video signals are transmitted locally to the production control facility for high-quality production, while a compressed low-resolution proxy feed is transmitted over the network for remote viewing and control. This segmentation allows each transmission path to be optimized for its specific purpose without compromising the other.
Solution Approach 2:
A proxy feed acts as an intermediary between the remote event site and the production control facility. The proxy feed provides a compressed representation of the event that can be transmitted over limited network bandwidth, enabling remote operators to view and control the production without requiring direct transmission of full-resolution video signals over the network.
2Productivity
If production equipment and personnel are deployed at remote event site, then production capability is improved, but cost and complexity increase significantly
Solution Approach 1:
The system merges the production control functions with the event site operations by enabling remote operators at the production control facility to directly control the switcher and production equipment at the event site. This consolidation allows a single production team to manage multiple event locations simultaneously, reducing the need for separate production crews at each site.
Solution Approach 2:
The remote production system enables self-service operation where the event site equipment automatically transmits video signals and the production control facility automatically receives and processes these signals. The system is designed to operate with minimal human intervention at the event site, reducing the need for on-site technical personnel while maintaining full production capability.
Data Source
AI summary
According to some embodiments, methods, systems, apparatus, 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 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. The resulting program is the broadcast program that can be broadcast and distributed.
