Bidirectional Remote Filming Control via Closed-Loop Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for remote location filming do not allow real-time control by the viewer, resulting in a one-way information flow from the filmer to the viewer, limiting the viewer's ability to experience the location as desired.
Innovation Solution
A bi-directional communication system that enables a client to send real-time control instructions to an operator, allowing the viewer to control the filming parameters such as pan-tilt-zoom and the operator's behavior, using a communication channel like the Internet, creating a closed-loop feedback system for dynamic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-recorded films are used to view a remote location, then the viewer can see the place without traveling, but the viewer cannot control the filming parameters or experience the location as desired
Solution Approach 1:
The patent implements a feedback mechanism where the viewer's control inputs (pan, tilt, zoom commands) are transmitted to the remote operator, who adjusts the camera accordingly. The viewer receives real-time video feedback showing the result of their control actions, creating a closed-loop control system that enables precise control of filming parameters from a remote location.
Solution Approach 2:
The patent introduces a communication system as an intermediary between the viewer and the remote camera operator. This intermediary transmits control commands from the viewer's device to the operator's device and relays video footage back to the viewer, enabling remote control without requiring the viewer to be physically present at the location.
2Loss of information
If a remote operator films a location, then the viewer can see the place, but information flows only one way from the shooter to the viewer without viewer control
Solution Approach 1:
The system establishes bidirectional information flow through feedback mechanisms. Control commands sent by the viewer are transmitted to the remote operator, and the operator's video responses are fed back to the viewer in real-time. This creates a two-way communication channel that eliminates the one-way information flow limitation of traditional remote filming.
3Adaptability or versatility
If the viewer wants to experience a location as desired, then physical travel is required, but this is not possible due to age, physical impairments, or other objective reasons
Solution Approach 1:
The system enables self-service remote exploration where the viewer independently controls the camera parameters (pan, tilt, zoom) to capture and view locations of their own choosing. The viewer serves themselves by making all control decisions without requiring a guide or predetermined filming plan, adapting the system to their specific viewing preferences and needs.

AI summary
A method and program product includes establishing a bi-directional communication channel with an operator's filming system. At least one command is communicated to the operator's filming system. The command at least includes instructions for conducting a filming, wherein the instructions are displayable on the operator's filming system. At least a real time stream of the filming is received. At least additional commands are communicated to the operator's filming system during the receiving, wherein the communicating, the receiving and the communicating during the receiving comprise a negative feedback loop during the filming.
