Viewpoint-Adaptive Advertisement Space in Free Viewpoint Video

The patent applies local quality by setting different advertisement spaces according to specific viewpoint conditions. Each viewpoint position, viewing direction, and view angle has its own designated advertisement space, ensuring that advertisement information is consistently delivered to users regardless of their viewing position. This resolves the contradiction by making advertisement delivery reliable (consistent across viewpoints) while maintaining high effectiveness (targeted to specific viewing conditions).

The patent implements dynamics by dynamically allocating advertisement spaces based on real-time viewpoint conditions. The advertisement space setting unit determines appropriate advertisement spaces according to the user's viewpoint position, viewing direction, and view angle, allowing the system to adapt advertisement delivery to changing viewing conditions. This dynamic approach ensures both consistency in delivery and effectiveness in distribution.

The patent applies segmentation by dividing the advertisement space into multiple regions corresponding to different viewpoint conditions. Each viewpoint position, viewing direction, and view angle has its own segmented advertisement space. This segmentation allows the system to effectively target advertisements to specific viewing conditions without requiring a completely complex system architecture, as each segment can be independently managed.

The patent implements universality through the advertisement space setting unit, which serves multiple functions: determining viewpoint conditions, selecting appropriate advertisement spaces, and managing multiple advertisement deliveries. This multi-functional unit reduces overall system complexity by consolidating what would otherwise require separate components for each function.
