Livestream Supplemental Content Timing for Fair Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livestream systems fail to account for client devices joining or leaving at different times, leading to unequal distribution of supplemental content and network resource spikes, resulting in some users missing content or experiencing delayed delivery.
Innovation Solution
Implementing non-concurrent supplemental content item loading by using timestamped markers and elapsed time thresholds to determine when client devices present content, distributing the load over time to reduce demand spikes and ensure equitable distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supplemental content items are presented at fixed times synchronized across all client devices, then the content distribution follows a traditional broadcast model, but client devices that join or leave at different times receive unequal amounts of supplemental content
Solution Approach 1:
The system transitions from static fixed-time supplemental content presentation to dynamic timing based on client device elapsed time. Each client device determines when to present supplemental content based on its own elapsed time metric, which accounts for when the device joined the livestream. This dynamic approach ensures that clients joining at different times receive appropriate supplemental content while maintaining equitable distribution across all users.
2Device complexity
If supplemental content items are presented at fixed synchronized times, then the broadcast model is simple to implement, but the content server experiences excessive demand spikes at those fixed times
Solution Approach 1:
The system implements periodic supplemental content presentation at multiple different times across the client population. Instead of all clients requesting supplemental content simultaneously at fixed intervals, each client device periodically checks its elapsed time and requests supplemental content at different moments. This distributes the periodic demand across time, eliminating demand spikes while maintaining the periodic nature of supplemental content delivery.
3Reliability
If all client devices request supplemental content simultaneously at fixed times, then the content delivery is synchronized, but network and processing resources are excessively utilized
Solution Approach 1:
The system segments the synchronized supplemental content request process into individual client device decisions based on elapsed time. Rather than all devices simultaneously requesting content at fixed times, each device independently determines its request timing based on its own elapsed time metric. This segmentation distributes the resource-intensive simultaneous requests across different time points, reducing overall network and processing resource utilization while maintaining reliable content delivery.

AI summary
The systems and methods disclosed herein relate to providing or presenting supplemental content non-concurrently during a livestream. In one embodiment, a method for providing supplemental content includes receiving from a client device a request for a supplemental content item; determining whether an elapsed time between the request for the supplemental content item and an earlier event exceeds a supplemental content interval; and responsive to determining that the elapsed time exceeds the supplemental content interval, causing the supplemental content item to be transmitted to the client device.
