Single-Buffer Video Stream Synchronization With Temporal Offsets

The patent merges multiple buffers into a single buffer structure that handles both input and output video frames. The display engine integrates warping and scaling operations within this unified buffer framework, eliminating the need for separate hardware buffers for each operation. This combining approach maintains full video processing capability while significantly reducing device complexity and hardware resource requirements.

The single buffer structure is designed to perform multiple functions: it stores input video frames, performs warping operations, executes scaling operations, and manages output display frames all within the same memory structure. This multi-functional buffer replaces what would traditionally require separate dedicated buffers for each operation, reducing overall system complexity while maintaining processing productivity.

The patent combines multiple separate hardware buffers into a single unified buffer structure that serves all video processing operations including warping, scaling, and frame buffering. This merging eliminates redundant hardware resources while maintaining the ability to process video frames through multiple operations sequentially or concurrently within the same buffer memory space.

Instead of allocating separate physical hardware buffers for each video processing stage, the system uses virtual buffer copies within a single physical buffer structure. Different buffer regions or logical buffer instances are created through software management rather than physical duplication, reducing actual hardware resource consumption while preserving processing capability.

The patent implements a synchronization mechanism that continuously monitors the state of the single buffer and adjusts timing parameters accordingly. The system tracks when input frames are written to the buffer and when output frames are read, using this feedback information to maintain proper synchronization between input and output streams. This feedback-based timing control ensures stream synchronization while using the simplified single-buffer structure.

The buffer management system dynamically adjusts timing and access patterns based on real-time conditions. The synchronization mechanism adapts buffer read/write timing, adjusts timing offsets, and modifies access sequences dynamically to maintain synchronization between input and output streams despite varying processing loads or timing variations, all while operating with the simplified single-buffer architecture.
