Multipoint Control Unit Code Stream Policy Adaptation

The patent segments the display policy into site-type-specific policies stored in a policy file. Instead of creating separate policies for each site, the system divides sites into types (e.g., single-screen site, multi-screen site) and assigns corresponding policies to each type. This segmentation allows the system to adapt to different site configurations automatically without requiring users to manually formulate policies for each site.

The patent creates a universal code stream processing policy file that can be applied to multiple site types. The policy file contains generic policies that work across different site configurations, making the system universally applicable. When a site joins the conference, the MCU automatically matches the site to its type and applies the corresponding universal policy, eliminating the need for site-specific policy customization.

The system implements self-service through automatic policy matching. When a site joins or its screen configuration changes, the MCU automatically determines the site type based on the number of screens and retrieves the corresponding policy from the policy file without user intervention. This self-service mechanism eliminates manual policy reformulation and reduces the time loss associated with configuration changes.

The patent prepares code stream processing policies in advance for different site types and stores them in a policy file before the conference starts. This preliminary action ensures that when sites join with different screen configurations, the appropriate policies are already available and can be immediately applied, avoiding the need for real-time policy creation or modification during the conference.
