Proximity-Based Content Filtering With Manifest Version Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When users with different content viewing preferences, such as adults and children, watch video content on their own devices in close proximity, there is a risk that children may inadvertently be exposed to unfiltered content intended for adults due to the proximity of the devices.
Innovation Solution
A user device detects the presence of users in proximity and switches between unfiltered and filtered content versions by accessing different manifests based on the identified users, ensuring that children are only shown filtered content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users with different content preferences watch video content on their own devices in close proximity, then each user can view content according to their preferences, but children may be exposed to unfiltered content intended for adults
Solution Approach 1:
The system segments content into multiple versions (filtered and unfiltered) and uses separate manifest files to deliver appropriate versions to different users. The user device receives and compares multiple manifests to determine which content version to output based on the detected audience composition.
Solution Approach 2:
The patent introduces an intermediary manifest file that acts as a mediator between the content delivery system and the user device. The manifest contains metadata about available content versions and delivery instructions, enabling the device to automatically select and switch between filtered and unfiltered content based on detected users without requiring direct user intervention.
2Ease of operation
If a single display device is used by multiple users, then content can be shared, but the presence of children forces censorship of content that adults want to view
Solution Approach 1:
The system dynamically switches between different content versions based on real-time detection of users in proximity to the device. The user device continuously monitors the audience composition and automatically transitions between filtered and unfiltered content versions without requiring manual reconfiguration or user intervention.
Solution Approach 2:
The system implements feedback through user detection mechanisms that monitor the presence and identity of users near the device. This feedback information is used to automatically adjust content delivery, switching between filtered and unfiltered versions based on whether children or only adults are detected in the vicinity.
3Reliability
If users watch content on separate devices, then content preferences can be maintained, but close proximity allows children to see unfiltered content on adult devices
Solution Approach 1:
The patent makes the content filtering system universal by enabling any user device to function as both a content consumer and a content monitor. The device not only receives content but also detects users in proximity and automatically adjusts its content output accordingly, making the filtering capability applicable to all devices in the vicinity regardless of which device is actively playing content.

AI summary
Methods, apparatuses, and systems are described for applying a content filter to a content item output via a user device. A user device may request a content item and receive a first manifest associated with the content item and a second manifest associated with the content item. The first manifest may be configured to deliver a first version of the content item and the second manifest may be configured to deliver a second version of the content item. Based on the user detected within proximity of the user device, the user device may access one of the manifests to output one of the versions of the content item.
