Playback Control System for Flexible Virtual Resource Adaptation

The patent segments the playback control system into multiple independent modules: a playback scene identification module, a virtual resource change condition determination module, and a virtual resource change module. Each module handles a specific function, allowing the system to manage different playback scenes and their corresponding virtual resource changes independently, thereby improving flexibility without overwhelming complexity.

The patent applies local quality by assigning different virtual resource change conditions to different playback scenes. Instead of using a uniform change condition for all playback scenarios, the system tailors specific conditions (such as playback duration thresholds or user interaction requirements) to each individual playback scene, enabling flexible and context-aware virtual resource changes.

The patent implements preliminary action by pre-defining and storing virtual resource change conditions for different playback scenes in advance. The system maintains a database or configuration file that contains the appropriate change conditions for each playback scene type, so that when a playback scene is identified, the corresponding pre-configured conditions are automatically retrieved and applied without requiring real-time complex calculations or decisions.

The patent employs feedback mechanisms where the system continuously monitors playback parameters (such as duration, user interactions, or completion status) and compares them against the predefined change conditions for the current playback scene. When the conditions are satisfied, the system provides feedback by triggering the virtual resource change, creating a closed-loop control system that enhances user experience while maintaining manageable complexity through automated condition evaluation.
