Camera Selection Interface for Live Event Media Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current live broadcast systems require a coordinated team of camera operators and directors to control and switch between multiple cameras, making it difficult to achieve high-quality broadcasts, especially with inexperienced teams, due to the need for explicit communication and understanding between team members.
Innovation Solution
A user interface system that allows a single user to control and switch between multiple cameras by displaying a context view and correlating camera views within it, enabling the user to adjust and switch camera perspectives using input devices or gestures, thereby generating a media presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coordinated team of camera operators and directors is used to control and switch between multiple cameras, then the quality of live broadcast can be maintained through explicit communication, but the system complexity and operational difficulty increase significantly
Solution Approach 1:
The patent combines the functions of multiple camera operators and directors into a single user interface system. The interface integrates camera selection, orientation control, and broadcast output switching into one unified system that a single user can operate, eliminating the need for coordinated teams while maintaining broadcast quality.
Solution Approach 2:
The user interface acts as an intermediary between the operator and multiple cameras. It provides visual feedback showing context views and camera orientations, and translates user inputs into coordinated camera control commands, simplifying the interaction complexity that would otherwise require multiple personnel.
2Manufacturing precision
If multiple camera operators focus on their viewfinders to capture well-composed shots, then individual shot quality improves, but the overall coordination and context awareness deteriorates due to limited periphery vision
Solution Approach 1:
The interface adds a new dimension of awareness by displaying context views that show the relative orientations and fields of view of multiple cameras simultaneously. This allows the operator to monitor all camera perspectives and contextual information in one view, rather than relying on limited periphery vision from individual viewfinders.
Solution Approach 2:
The system provides visual feedback by displaying context views that show how each camera is oriented relative to the event and other cameras. This feedback loop allows the operator to make informed decisions about camera selection and orientation while maintaining awareness of the overall scene context.
3Manufacturing precision
If a director relies on a bank of live monitors to select camera angles, then the ability to choose best shots improves, but the communication and understanding between director and camera operators becomes more difficult
Solution Approach 1:
The user interface performs multiple functions that were previously distributed between the director and camera operators. It provides camera angle selection, orientation control, and visual feedback in a single system, allowing one user to perform what previously required coordinated efforts of multiple personnel.
Solution Approach 2:
The system enables the operator to independently select and control camera angles without needing continual dialogue with camera operators. The interface self-manages the complexity of coordinating multiple camera views, allowing the operator to directly control the broadcast quality through the unified interface.
Data Source
AI summary
To generate a media presentation of a live event, a user interface is coupled to at least three cameras that share substantially the same vantage point. One of the cameras (e.g., a context camera) provides a context view of the event that is displayed on a screen of the user interface. The views of the other two cameras are superimposed onto the context view to define sub-portions that are visually demarcated within the context view. Based on user interaction, the user interface can switch between the cameras views and control the cameras to capture different portions of the context view. Based the image data captured by the views of the cameras within the context view, the user interface generates a media presentation that may be broadcast to multiple viewers.
