Remote Video Production via Wide Area Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Outside Broadcasting (OB) buses face challenges in transportation, cost, environmental impact, and limited capabilities, especially when broadcasting events over large distances, where it is difficult to establish efficient remote video and audio production systems that can communicate effectively between a control room and a remote site using available bandwidth.
Innovation Solution
A system utilizing a wide area network, such as the Internet, to establish two signal paths for communication between the control room and the remote site, with one path providing zero-time-delay primary data for real-time video and audio signals and another path for secondary data with lower quality of service, including camera and audio control, error management, and voice communication, using communication matrices to enable seamless interaction between crew members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional OB Bus is used for remote video production, then real-time video and audio signals can be transmitted, but transportation cost, travel time, and environmental impact increase significantly
Solution Approach 1:
The patent extracts the control room functions from the physical OB Bus and implements them remotely via internet connection. The second part (remote site) maintains camera and audio equipment while the first part (control room) operates from a distant location, eliminating the need to transport the entire OB Bus to the event location while preserving real-time signal transmission capabilities.
Solution Approach 2:
The patent makes the system universally accessible by enabling control room operations from any location with internet connectivity. The dual-path communication system (first path for video/audio, second path for control data) provides multi-functional capability to handle both real-time media transmission and remote control operations through a single remote production architecture.
2Ease of operation
If OB Bus is transported to remote sites, then on-site production capability is improved, but the bus cannot reach hard-to-access locations
Solution Approach 1:
The control room functions are extracted from the physical OB Bus and operated remotely via internet connection. This allows the production capability to be accessed from any location without being constrained by the physical mobility of a large bus, enabling hard-to-reach locations to be accessed while maintaining full production capabilities.
3Device complexity
If all data is transmitted through a single communication path, then system complexity is reduced, but bandwidth optimization and signal prioritization become difficult
Solution Approach 1:
The patent segments the data transmission into two distinct paths: a first path dedicated to real-time video and audio signals requiring high bandwidth and zero time delay, and a second path for control data and metadata with lower bandwidth requirements. This segmentation optimizes bandwidth utilization for each data type while maintaining manageable system complexity through clear separation of functions.
Data Source
AI summary
The present invention relates to a system for remote video and/or audio production, which system comprises a first part related to the control room for the video production and a second part on the site of an event to be recorded, and where the first and second part communicate with each other by means of a data stream. It is proposed that the data stream is adapted to be sent between the first and second part by means of a wide area network.
