ROI Calculation Logic

Implementing this technology could reduce retransmission requests by an average of 20%, easing data center traffic load. This may lead to annual power cost reductions of ~$50K (AI est.), server resource cost savings of ~$50K (AI est.), and a ~$50K (AI est.) reduction in retransmission-related incident response labor. Total estimated annual cost savings could reach ~$150K (AI est.), with improved broadcast quality also contributing to lower customer churn.

Speed to Market
6× faster than in-house development
This technology features a well-defined retransmission algorithm for error correction coded data and an established logic for variable encoding rate control based on IP network packet loss. This could significantly reduce the R&D period from over 3.0 years (for in-house development) to as little as 0.5 years through licensing. With the core technology already proven, licensees can focus on integration into existing systems, dramatically shortening time-to-market and accelerating revenue generation.
