Hybrid operating rooms are an important development in the medical ecosystem. They allow integrating, in the same procedure, the advantages of radiological imaging and surgical tools. However, one of the challenges faced by clinical engineers is to support the connectivity and interoperability of medical-electrical point-of-care devices. A system that could enable plug-and-play connectivity and interoperability for medical devices would improve patient safety, save hospitals time and money, and provide data for electronic medical records. In this paper, we propose a hardware platform dedicated to collect and synchronize multiple videos captured from medical equipment in real-time. The final objective is to integrate augmented reality technology into an operation room (OR) in order to assist the surgeon during a minimally invasive operation. To the best of our knowledge, there is no prior work dealing with hardware based video synchronization for augmented reality applications on OR. Whilst hardware synchronization methods can embed temporal value, so called timestamp, into each sequence on-the-y and require no post-processing, they require specialized hardware. However the design of our hardware is simple and generic. This approach was adopted and implemented in this work and its performance is evaluated by comparison to the start-of-the-art methods.
