Live Stream Display Error Detection With Dynamic Pixel Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In amusement parks, managing interactive and live-rendered video streams on rides is challenging due to the difficulty in detecting unexpected display issues, which can lead to inefficient operations and poor guest experiences.
Innovation Solution
A video stream management system that embeds a dynamic pixel pattern in the video stream to monitor for errors and automatically switch to an alternative stream when discrepancies are detected, ensuring seamless viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If b-roll content is overlaid on live stream footage to fill dead air, then viewer engagement and content richness are improved, but the risk of displaying incorrect or outdated information increases
Solution Approach 1:
The system pre-loads multiple versions of b-roll content (e.g., different product images, pricing information, or promotional materials) into the overlay buffer before the live stream occurs. This preliminary preparation allows the system to quickly switch between pre-vetted content options without real-time processing delays, ensuring both flexibility in content selection and reliability in information accuracy.
Solution Approach 2:
The system continuously monitors the live stream for anomalies such as price changes, product updates, or stream interruptions, and automatically adjusts which pre-loaded b-roll content is displayed. This feedback mechanism ensures that the overlay content remains accurate and relevant throughout the stream, resolving the contradiction between content flexibility and information reliability.
2Speed
If real-time overlay content is generated during live stream, then responsiveness to current events is improved, but processing delays and system complexity increase
Solution Approach 1:
The system generates and prepares multiple b-roll content versions in advance during off-peak times or before the live stream begins. By pre-generating content based on predicted stream scenarios and storing them in a buffered overlay system, the patent eliminates real-time processing complexity while maintaining fast response capability through instant switching between pre-prepared content options.
3Adaptability or versatility
If multiple video streams are managed simultaneously, then viewer options and content variety are improved, but stream management complexity and errors increase
Solution Approach 1:
The system segments the video stream management into distinct independent components: a primary live stream pipeline, multiple pre-generated b-roll content pipelines, and an overlay composition pipeline. Each pipeline operates independently with its own error handling and switching mechanisms, allowing the system to manage multiple streams simultaneously while reducing overall complexity through modular architecture.

AI summary
A video stream controller configured to generate a primary video stream and receive a dynamic pixel pattern from a memory of the video stream controller. The dynamic pixel pattern comprises a changed pixel pattern for each frame of the primary video stream. The video stream controller is configured to embed the dynamic pixel pattern in the primary video stream to obtain an embedded dynamic pixel stream, and send the embedded dynamic pixel stream for display on a display. The video stream controller is configured to monitor one or more images on the display to identify an error based on a mismatch between the dynamic pixel pattern and an image of the one or more images on the display, and switch to sending an alternative video stream to the display in response to the error being identified.
