Multi-Camera Live Stream Control With Low-Bandwidth Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not allow for real-time control and editing of live streams from multiple camera applications on client devices, requiring manual control of each device individually and lacking centralized management.
Innovation Solution
A director application on a controller device can remotely control and edit live streams from multiple camera applications on client devices, allowing for centralized management, real-time adjustments, and synchronized editing across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of each camera application is used, then individual device operation is maintained, but centralized management and coordination are lost
Solution Approach 1:
The patent introduces a director device as an intermediary between multiple camera applications. The director application on the controller device receives control inputs and distributes them to appropriate camera applications, enabling centralized management without requiring direct complex interconnections between all camera devices. This mediator architecture resolves the contradiction by providing centralized control while maintaining manageable system complexity through a hierarchical structure.
2Loss of information
If real-time live stream transmission is implemented, then centralized monitoring is enabled, but network bandwidth and data transmission requirements increase
Solution Approach 1:
The patent implements local quality by allowing each camera application to capture and process video at full quality locally, then transmit only essential control data and selected video feeds to the director device. The director application can request specific video streams or metadata rather than all camera feeds simultaneously. This approach enables effective centralized monitoring while reducing network bandwidth consumption by transmitting only necessary data at appropriate quality levels.
3Productivity
If multiple camera applications are coordinated through a single interface, then operational efficiency improves, but control flexibility for individual devices decreases
Solution Approach 1:
The patent segments the control system into hierarchical levels: the director application provides high-level coordinated control for production efficiency, while each camera application maintains its own local control interface for individual device flexibility. The segmentation allows control to be distributed appropriately - routine coordinated operations are managed centrally for productivity, while individual device adjustments can still be made locally when needed, preserving adaptability without sacrificing coordination efficiency.

AI summary
A director application executing on a controller device can be paired with multiple camera applications operating on respective client devices. The cameras on the respective client devices can be (a) controlled remotely by the director application in communication with the camera applications or (b) directly through a GUI of the camera applications. The client device can be controlled individually or as a group. Each client device transmits a first version of a live stream to the controller device and stores a second version of the live stream locally. The first version may be a lower quality version or otherwise different than the second version. Edits to attributes of the live stream can be made to the first, lower quality version of the live stream provided to the director device and subsequently applied to a second, higher quality version of the live stream.
