+
+### 📋 Additional Representations
+
+---
+
+## ⏱️ Data Synchronization Approach
+
+
+*Each modality (DeckLink cameras, USB cameras, and robotic kinematics) was recorded time-stamped on the same PC. A post-processing synchronization script segmented trials using explicit start/end markers and used the kinematic time series as the reference timeline. For each kinematic timestamp, the temporally nearest image frame from each camera stream was selected. The original stereoendoscope of the system is capable of only ~20FPS, thus the <50ms delay can not always be ensured.*

+
+### 📋 Additional Representations
+
+---
+
+## ⏱️ Data Synchronization Approach
+
+
+*Each modality (DeckLink cameras, USB cameras, and robotic kinematics) was recorded time-stamped on the same PC. A post-processing synchronization script segmented trials using explicit start/end markers and used the kinematic time series as the reference timeline. For each kinematic timestamp, the temporally nearest image frame from each camera stream was selected. The original stereoendoscope of the system is capable of only ~20FPS, thus the <50ms delay can not always be ensured.*
