ROI Calculation Logic

Assuming an average 5% user churn rate due to video quality degradation in online video streaming services, and a reduction to 1% with this technology. For a service with 1 million monthly active users and an average monthly subscription of ~$6.70 (AI est.), annual revenue opportunity loss could be reduced by ~$3.2M (AI est.). This technology is estimated to contribute ~30% of that, resulting in an economic impact of ~$1.0M per year (AI est.).

Speed to Market
6× faster than in-house development
This technology features established algorithms for packet priority determination and discard control, primarily relying on software implementation. This results in low barriers to integration with existing network infrastructure. While developing similar technology from scratch could take approximately 3 years for conceptual design, verification, and optimization, licensing this patent could reduce that timeline to about 6 months, significantly accelerating time-to-market. This allows adopting companies to quickly capture first-mover advantages.
