Duration: 3 months
Evaluate compatibility with the licensee's existing distribution infrastructure and define integration goals and requirements. Conduct a small-scale Proof of Concept (PoC) to verify the basic QoE improvement effects.
Phase 2: System Development & Testing
Duration: 6 months
Develop and integrate the rate control server module into the existing system based on defined requirements. Perform functional verification and performance evaluation in an integrated test environment, making adjustments for stable operation.
Phase 3: Production Deployment & Optimization
Duration: 3 months
Implement a phased rollout to the production environment, monitoring QoE and optimizing parameters based on actual user data. Establish a continuous improvement cycle to maximize the technology's effectiveness.
Technical Feasibility
This technology is designed to integrate into existing video distribution systems as a software-based 'rate control server' functional module. The patent claims describe logical components such as the data information management unit, data reception unit, quality calculation unit, and quality transmission unit. These components can interface with existing distribution infrastructure via APIs and protocols, enabling relatively easy system integration without requiring significant hardware investment or a complete overhaul of the infrastructure.
Success Scenario
Upon adoption, a licensee's video distribution service could consistently provide optimal QoE to all users, regardless of network bandwidth fluctuations. This is estimated to improve user retention rates and increase average viewing times. Consequently, an increase in paying subscribers and maximized advertising revenue could be expected, significantly enhancing service value.
