In real-time video applications, accurate end-to-end delay measurement is crucial for improving transmission efficiency and user experience. This study proposes PD-Timestamp, a novel timestamp representation method that combines pointers and digits: pointers denote millisecond-level time units, while numerical values represent second-level time units. This method effectively addresses the issue of overlapped timestamps resulting from multiple exposures during video capture. Additionally, it is applied to Capture-to-Display Delay (CDD) measurement in real-time video, enabling non-intrusive and accurate CDD evaluation. Experimental results demonstrate that PD-Timestamp achieves a timestamp recognition accuracy of 98.82%, underscoring its effectiveness in end-to-end delay measurement for real-time video transmission.

摘要

In real-time video applications, accurate end-to-end delay measurement is crucial for improving transmission efficiency and user experience. This study proposes PD-Timestamp, a novel timestamp representation method that combines pointers and digits: pointers denote millisecond-level time units, while numerical values represent second-level time units. This method effectively addresses the issue of overlapped timestamps resulting from multiple exposures during video capture. Additionally, it is applied to Capture-to-Display Delay (CDD) measurement in real-time video, enabling non-intrusive and accurate CDD evaluation. Experimental results demonstrate that PD-Timestamp achieves a timestamp recognition accuracy of 98.82%, underscoring its effectiveness in end-to-end delay measurement for real-time video transmission.
