Secondary Device Authentication for Multi-Perspective Audiovisual Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users watching audiovisual data streams on primary devices often have unsatisfactory experiences due to limited control over selected data and inability to communicate effectively with others, as they cannot easily switch between different perspectives or interact with the content in real-time.
Innovation Solution
A method for authentication and synchronous interaction between secondary devices and primary devices, allowing users to select different perspectives of an audiovisual data stream, annotate content, and wager, while enabling communication and data transfer, based on geospatial proximity, using modules for multi-perspective data stream processing and synchronous interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a technician controls which data is captured by different capture devices during live performance, then the broadcast can be professionally produced, but the user cannot select different perspectives or communicate with other users
Solution Approach 1:
The system segments control authority between the primary device (technician control) and secondary devices (user control). Each secondary device receives authenticated access to control specific aspects of the audiovisual stream, allowing multiple users to independently select perspectives and annotate content without interfering with each other or the primary broadcast control.
Solution Approach 2:
The patent introduces secondary devices as intermediary interfaces between users and the primary broadcast system. These secondary devices authenticate users and translate their selections into control signals that modify the audiovisual stream displayed on both the secondary device and the primary device, enabling user interaction without direct access to capture devices.
2Adaptability or versatility
If users watch audiovisual data stream on primary device, then they can view the broadcast, but they cannot easily switch between different perspectives or interact with content in real-time
Solution Approach 1:
Secondary devices are designed with multi-functionality, serving as both viewing displays and control interfaces. They can display the audiovisual stream, select different camera angles and perspectives, annotate content, and communicate with other users—all through a single authenticated device interface, reducing the need for multiple separate systems.
Solution Approach 2:
The patent adds a new dimension of interaction by allowing annotations to be overlaid on the audiovisual stream. These annotations exist in a separate layer that can be created, viewed, and interacted with independently of the video content, enabling real-time commentary and communication without interfering with the primary broadcast.
3Reliability
If secondary device is authenticated based on geospatial proximity, then security is improved, but the system must handle devices at disparate locations
Solution Approach 1:
The authentication system dynamically adjusts its criteria based on the situation. Geospatial proximity is used as an initial authentication factor for local devices, while network-based authentication mechanisms enable devices at disparate locations to be authenticated. The system adapts its security requirements based on the device's location and the nature of the interaction.
Solution Approach 2:
The patent changes the authentication parameters from strictly geospatial-based to a multi-factor approach that includes geospatial proximity, network credentials, and device identification. This allows the system to maintain security while accommodating devices whether they are physically near the primary device or located remotely, by adjusting which authentication parameters are required based on the connection type.

AI summary
A method of authentication and synchronous interaction between a secondary device and a multi-perspective audiovisual data stream broadcast on a primary device geospatially proximate and/or geospatially disparate to the secondary device is disclosed. In one aspect a method of secondary device includes authenticating the secondary device to a primary device based on a geospatial proximity and/or geospatial disparity of the secondary device and the primary device such that the secondary device is synchronizable with the primary device. The secondary device is synchronized to the primary device such that an audiovisual data stream of the primary device is adjustable through the secondary device. An audiovisual data stream of the primary device may be processed such that the audiovisual data stream is accessible through the secondary device. The audiovisual data stream may be an audiovisual data stream of a live performance of an event.
