Server-Based Video Session Shifting via Playlist Generation

The patent introduces a server-based intermediary system that mediates between different client devices and the video streaming content. The server tracks viewing history and session state, then redirects playback to appropriate devices without requiring device-specific protocols or client modifications. This intermediary approach enables universal video session shifting across any device while maintaining compatibility with existing client applications.

Instead of modifying client-side applications to enable session shifting (the conventional approach), the patent inverts the architecture by implementing session shifting logic on the server side. The server actively manages session state, tracks viewing history, and controls playback redirection, thereby eliminating the need for client customization while achieving the same functional goal.

The server acts as an intermediary that maintains session continuity by tracking viewing history and session state independently of client devices. The server stores playback position and session information, then redirects to appropriate devices without requiring client-side customization. This approach ensures reliable session continuity while maintaining adaptability across different device types and protocols, as the server abstracts device-specific details.

The patent inverts the conventional approach by moving session continuity management from the client side to the server side. Instead of each device maintaining its own session state and continuity logic, the server centrally manages session continuity, thereby achieving both reliable session persistence and broad device adaptability without client customization requirements.
