Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing real-time event broadcasting systems limit the amount of information conveyed to consumers by treating camera streams as fundamental data units rather than composite data from multiple sensors, restricting efficient information presentation and bandwidth utilization.
Innovation Solution
A multi-sensor solution that captures and transmits composite image and data streams from various sensors, including CCD, CMOS, and non-image-based sensors, with prioritization algorithms and interpolation processes to enhance user experience and optimize bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If camera streams are treated as fundamental data units, then the system is simple to implement, but the amount of information that can be conveyed is limited
Solution Approach 1:
The patent segments the camera stream into multiple independent sensor data streams (image data, depth data, motion data, audio data) that can be processed and transmitted separately. This allows selective transmission of only the necessary sensor data types, increasing information conveyance efficiency while managing bandwidth resources.
Solution Approach 2:
The patent transitions from treating camera output as a single 2D image stream to a multi-dimensional data structure incorporating depth information, motion vectors, and audio spatial positioning. This dimensional expansion enables richer scene representation and more effective information conveyance to the display device.
2Loss of information
If all sensor data is transmitted, then comprehensive information is provided, but bandwidth consumption increases
Solution Approach 1:
The patent extracts and identifies the most critical sensor data types needed for the specific application scenario. Based on the extracted data, the system selectively transmits only those sensor streams that are most important for the current viewing context, thereby reducing unnecessary bandwidth consumption while preserving essential information.
Solution Approach 2:
The patent applies different quality levels and transmission priorities to different sensor data types based on their local importance. Critical data such as image data and motion vectors receive higher priority and better quality transmission, while less critical data like certain depth or audio streams may be transmitted at lower quality or selectively omitted, optimizing the bandwidth-quality tradeoff.
3Ease of operation
If multi-sensor data is processed in real-time, then user experience is enhanced, but processing time and complexity increase
Solution Approach 1:
The patent performs preliminary processing and prioritization of sensor data at the source devices (cameras and sensors) before transmission. Each device pre-processes its output to identify and tag the most important data elements, reducing the processing burden on the central server and enabling faster real-time assembly of the final composite stream.
Solution Approach 2:
The patent establishes continuous, optimized data flow paths where sensor data is continuously processed and prioritized as it is generated. This continuous prioritization mechanism ensures that the most important data is always ready for immediate transmission and display, maintaining real-time responsiveness without requiring intensive batch processing that would introduce delays.
