Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital video conference systems face challenges in managing multiple participants, handling diverse information formats, ensuring low latency and high quality, and synchronizing video streams across users, particularly in scenarios where participants are both local and remote, and there is a need to identify user participation clearly.
Innovation Solution
A method involving authentication of users, capturing multiple video streams from different angles, applying one-way functions to embed authentication tokens, and using automatic production decisions to create interactive video streams with embedded information, while down-sampling and storing metadata for enhanced video production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple video streams from different participants are captured and processed, then user identification and interaction quality are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system segments video streams by capturing them from multiple different viewpoints (first primary video stream, fourth primary video stream, etc.) and processes each stream independently through one-way functions to extract authentication tokens. This segmentation allows reliable user identification while managing system complexity through modular processing of individual streams rather than attempting to analyze all streams simultaneously as a single complex task.
Solution Approach 2:
One-way functions serve as intermediaries between the captured video streams and the authentication token extraction process. These functions process the video stream data (including authentication video parts) to generate authentication tokens without requiring complex direct analysis of multiple streams, thereby improving user identification reliability while keeping the system architecture manageable through this intermediary processing layer.
2Reliability
If authentication tokens are embedded in video streams through one-way functions, then security and user verification are improved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary action by capturing authentication video parts during the initial video stream capture phase (first primary authentication video part, fourth primary authentication video part). This authentication data is prepared and ready for one-way function processing before the actual authentication verification occurs, reducing the computational burden and time required during the critical authentication moment while maintaining security.
Solution Approach 2:
The patent replaces complex mechanical or manual authentication verification systems with one-way cryptographic functions that process video stream data. This substitution provides robust authentication security through mathematical principles rather than complex procedural systems, improving reliability while actually reducing processing time compared to traditional multi-step authentication mechanisms.
3Measurement precision
If multiple primary video streams are captured and processed through one-way functions, then authentication accuracy is improved, but data processing complexity and resource consumption increase
Solution Approach 1:
The system divides the authentication process into segments by processing different primary video streams (first primary video stream, fourth primary video stream) through separate one-way functions. Each stream contributes independently to the authentication accuracy, allowing the system to achieve high measurement precision through multiple independent verification paths while managing data processing complexity through this segmented approach rather than attempting to process all streams in a single complex operation.
4Productivity
If video streams are down-sampled and metadata is stored, then storage efficiency and transmission speed are improved, but video quality and detail are reduced
Solution Approach 1:
The system extracts only the essential authentication information and metadata from the full video streams through one-way functions, storing this extracted data separately from the complete video content. This extraction approach improves transmission speed and storage efficiency by handling only the critical authentication tokens and metadata, while the full-quality video streams are preserved for when complete video quality is required, thus resolving the contradiction between transmission efficiency and video quality.

AI summary
Methods and systems for producing a video stream. A first user is authenticated. A first primary video stream is captured showing the first user and comprising a first primary authentication video part. A fourth primary video stream is captured, visually showing the first user from a different point of view, comprising a fourth primary authentication video part. One-way functions of the first and fourth primary video streams are calculated, each being calculated using the respective primary authentication video part. The produced video stream is automatically produced based on the first primary video stream. For each of the one-way function outputs, the output is embedded into a least one of the video streams so that the embedding depends on content in a video stream which is not the same as the video stream into which the embedding is made. The output is stored and/or publicly published.
