Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconferencing systems face challenges in achieving high resolution and quality for multiple videostreams simultaneously, limiting their scalability and user experience.
Innovation Solution
The conference device employs multiple image sensors and processors to generate primary and secondary videostreams, with an intermediate processor combining these streams to provide a field-of-view and region-of-interest videostream, allowing for flexible and high-quality viewing options while reducing processing burdens by leveraging the original image data without loss of quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple videostreams are generated simultaneously from single image data, then video quality and resolution are maintained, but processing complexity and computational burden increase
Solution Approach 1:
The patent divides the video processing into multiple independent streams (first videostream, second videostream, third videostream) that are generated simultaneously from the same image data. Each stream is processed independently through separate image processors, allowing parallel computation that maintains video quality while distributing the processing burden across multiple specialized units rather than overwhelming a single processor.
Solution Approach 2:
The system performs preliminary processing of the image data to create multiple videostreams before transmission or further processing. By pre-generating these streams with appropriate resolutions and formats, the system reduces the computational burden on downstream devices, as the heavy lifting of multi-stream generation is already completed by the conference device's image processors.
2Measurement precision
If high resolution videostreams are provided for multiple views, then user experience is improved, but bandwidth requirements and system costs increase
Solution Approach 1:
The patent assigns different resolutions to different videostreams based on their specific purposes. The first videostream is generated at a first resolution, the second videostream at a second resolution, and the third videostream at a third resolution. This local quality approach ensures that each stream has the appropriate resolution for its intended use, optimizing bandwidth utilization while maintaining high quality where needed rather than uniformly applying high resolution across all streams.
3Adaptability or versatility
If multiple image processors are used to generate multiple videostreams, then multi-view capability is achieved, but device complexity and cost increase
Solution Approach 1:
The patent designs the image processors to be multi-functional units that can generate multiple types of videostreams (first, second, and third streams) with different resolutions and formats. This universality allows the system to achieve multi-view capability without requiring a separate dedicated processor for each stream type, thereby reducing overall device complexity while maintaining versatility.
