Server-Side Trick Mode Restrictions for VOD ABR Streaming

The patent transforms static VOD playlists into dynamic playlists that can be updated in real-time during playback. The server dynamically generates playlists by inserting interstitial content at designated positions and controlling playback position, enabling the system to adapt to real-time requirements while maintaining the underlying VOD stream structure.

The patent segments the VOD stream into multiple segments or chunks that can be independently managed. By dividing the continuous stream into discrete segments, the system can insert interstitial content between segments and enforce trick mode restrictions on specific segments without affecting the entire stream, thus achieving real-time adaptability.

The patent implements a feedback mechanism where the server monitors playback position and user behavior in real-time. When a user attempts to skip sections or access content outside the authorized playback range, the system detects this through feedback signals and responds by adjusting the playlist or blocking the skip attempt, thus enforcing trick mode restrictions while maintaining monetization capabilities.

The patent applies preliminary anti-action by pre-configuring the playlist with interstitial content at specific positions and pre-establishing trick mode restrictions before playback begins. The system proactively prevents skipping by controlling the playback position through playlist management, ensuring that users cannot access content before authorized points or skip designated interstitial sections.
