Audio Video Synchronization Without Embedded Timestamps

The patent extracts and eliminates the need for embedded timestamps and central-clock recovery mechanisms from the synchronization system. By removing these complex components, the system achieves synchronization without relying on them, thereby reducing device complexity while maintaining accuracy through alternative means (packet timing information and processing delays).

The system uses self-service by having the audio and video streams themselves carry the timing information needed for synchronization through their packet structures and processing characteristics. The streams synchronize themselves through their inherent timing properties rather than requiring external clock recovery or embedded timestamp mechanisms.

The patent removes the expensive embedded timestamp infrastructure and central-clock recovery mechanisms from the system. This extraction eliminates the need for costly hardware and complex processing while maintaining synchronization accuracy through simpler packet-based timing methods, thereby reducing manufacturing cost.

The system replaces expensive, complex synchronization hardware with simpler, more economical software-based timing mechanisms that process packet information and calculate delays. This substitution uses computationally lightweight methods instead of costly hardware infrastructure, reducing manufacturing cost while achieving the same synchronization function.

The patent introduces intermediary timing information embedded within the packet structures of audio and video streams themselves. These timing intermediaries (packet timestamps, sequence numbers, and delay calculations) serve as mediators that enable synchronization without requiring external embedded timestamps or complex clock recovery, thus maintaining accuracy while keeping the system simple.

The system replaces mechanical clock recovery mechanisms with computational timing methods that process packet data and calculate synchronization delays through software algorithms. This substitution uses information processing instead of hardware-based clock synchronization, maintaining accuracy while reducing device complexity.
