Architectural Layers & Regulatory Standards

• Operating Room Video Capture & Normalization (12G-SDI / HDMI 2.1 / SMPTE ST 2110 IP Video): Ingesting uncompressed 4K 60 FPS video feeds from surgical robots (da Vinci), laparoscopes, and room cameras.
• Sub-Frame Video Compression & Encoding (Ultra-Low Latency HEVC / JPEG XS Hardware Encoders): Compressing surgical video with glass-to-glass latency under 50 milliseconds across fiber and dedicated 5G slices.
• Bidirectional Interactive Telestration (Sub-Millimeter Touch/Stylus Drawing Engine): Allowing the remote mentoring surgeon to draw anatomical incision planes directly onto the live operative video stream.
• Legal, CME & Hospital Compliance (Automated Surgical Video De-Identification & Archival): Recording surgical interventions for quality review, proctoring credentials, and continuous surgical training.

Key Metrics: < 50 ms (Glass-to-Glass Intraoperative Latency) | 4K 60 FPS (Uncompromised Surgical Video Resolution) | < 10 ms (Telestration Drawing Synchronization) | SMPTE 2110 (Broadcast Medical Video Standard)
