Synchronized Second Screen Content Trigger Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for synchronized supplemental content that minimizes network bandwidth impact during second screen experiences, as users want seamless integration with primary content while maintaining fast network speeds.
Innovation Solution
The system employs a subset of interfaces to report trigger receipt information, allowing the trigger source to adjust timing, and uses zone grouping to optimize trigger detection and synchronization, with algorithms determining reporting based on statistical data and multipliers to reduce network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all interfaces report trigger receipt information, then synchronization accuracy is improved, but network bandwidth consumption increases
Solution Approach 1:
The system segments the population of interfaces into multiple zones based on geographic location. Each zone independently selects a subset of interfaces to report triggers, rather than having all interfaces report. This segmentation reduces the total number of reports while maintaining synchronization coverage across all areas.
Solution Approach 2:
Instead of requiring all interfaces to report trigger receipt information, the system implements partial action by selecting only a subset of interfaces within each zone to report. This partial reporting is sufficient to achieve the desired synchronization accuracy while significantly reducing network bandwidth consumption.
2Reliability
If subset size is increased, then synchronization reliability is improved, but network traffic increases
Solution Approach 1:
The system dynamically adjusts the subset selection based on statistical information about trigger detection patterns in each zone. The subset size and composition are not fixed but adapt to actual usage patterns, optimizing the balance between reliability and network traffic efficiency.
Solution Approach 2:
The system uses feedback from reported triggers to adjust future subset selections and timing. Statistical information about which interfaces detect triggers most frequently informs the selection process, improving synchronization reliability while minimizing unnecessary network traffic from interfaces that rarely detect triggers.
3Productivity
If zone grouping is implemented, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The system segments interfaces into geographic zones to improve network efficiency. This segmentation organizes the large number of interfaces into manageable groups, making it feasible to implement selective reporting without overwhelming system complexity.
Solution Approach 2:
The system changes the parameter of interface identification from individual interface IDs to zone-based groupings. This parameter change simplifies the management of large numbers of interfaces by aggregating them into zones, reducing the complexity of tracking and managing individual interface states.

AI summary
The disclosure relates generally to providing synchronized supplemental content. In one aspect, second user devices may be used to consume supplemental content associated with primary content presented on a first display. The supplemental content may be synchronized with the primary content. Such synchronization may be performed by detecting and reporting triggers within the primary content and transmitting synchronization signals to appropriate second user devices. Another aspect of the disclosure relates to determining which interfaces or applications will report the triggers, and fine-tuning how many interfaces or applications will report the triggers.
